I have restored an old Honda cg125 that has not been used for about 3 years. Everything on it has been cleaned, powder coated and replaced where necessary and it looks a treat. I have got it running but it is very load, way loader than normal and it almost sounds dry or tinny. Engine has not been apart as it was running ok when it was parked up.I have checked oil pressure and it’s all good with fresh oil. It also misfires a bit and I’m wondering if it’s the replacement exhaust I have fitted. It...

Hello all

Hello!

I picked up a CB250N Honda Super-dream at the start of the year, with the intention of making it into a summer commuter bike. Here is my progress so far;

Bike details;
I bought the bike of eBay, unseen. It ran okay (ish) but was difficult to start and had been basically sat since 1984. The bike has all the original paperwork which indicates it was bought new from Honda, riden for 10,000 miles, then stored/sold/stored/sold until 2019.

After cleaning and dismantling, I found a few...

Afternoon all,

Having read quite a few project reports on this forum I would like to add my own.
Will be posting the refurb on VJMC Kawasaki technical forum too.

Now that's out of the way here is a potted history of the bike.

Out of the crate and rode home on trade plates by me.

hello

i have recently bought my first bike (very new to all this) and all was running well until today when upon shifting from first to second the engine cut out and will no longer start. it will also not bump start, but is turning over. the kick starter has also gone quite slack. bike is 1988 suzuki dr125, any suggestions please.

Hi,
total newbie here, so please be gentle.

My uncle was an enthusiast of old motorbikes. He passed around 4 years ago.
His bikes have been in my very elderly aunts garage since.
I have NOT seen these (tho I knew they existed) but have no idea of condition, or if he had taken some apart to tinker with and they were never reassembled.

She says they are all running, but as I say, I suspect that is unlikely.

The list she gave me (he had written down what he had) is:
rudge 250 special 1937...

I found this on YouTube today . Absolutely inspirational . Start the vid at the beginning .

Morning,

I'm going to see a ZXR750 L1 this weekend. Is there anything bar the usual bike stuff I need to look out for on these bikes? I used to have a J about 25 years ago but it was back when I didn't know what I was doing with bike maintenance, couldn't even ride the thing properly.

Thanks,

Mark

Just bought an Xj900s, low mileage, great condition, 1998, was running ok but rich on 1,2 and 4 carbs.
Took carbs off and found needle assemblies in bits in 1,2 and 4. Reassembled them, clearly need new o rings, but didn’t have any. Put carbs back on bike and now can’t get any fuel through to them. Electric fuel pump isn’t running when cranking engine. Took fuel pump off, rigged up temporary supply and pump runs.
Why am I not getting 12v at the fuel pump? What have I missed? Thanks

Has anyone in the Coventry / Birmingham or West Midlands area got a project bike for me to restore over the winter ? Absolutely anything considered except scooters and Chinese bikes .

the cn/ch 250 honda is a generic part. its wiring is obvious. yellow means stator. each yellow wire is a phase. stator phases get added through the rectifier. red means positive. green must be ground, what elese could it be? what about black. so why does honda use green. it has to do with the golden age of motorcycles.

once upon a time the rec and the reg used to be two different units. the ignition wire to the regulator was black. this is no longer true on any magnito bike except mine. I do...

Hi,

I am new to the forum and joined hoping to get some advice on what sort of 125cc bike would make a good restoration project and learner bike. I have been restoring / building peddle bikes for years and have rebuilt a mini and a Triumph spitfire. I am however entirely new to working on motorbikes.

Any advice on where to start looking and what to look for would be greatly appreciated.

Thanks

Got my new winter project sorted . I might invest in a new wire brush before I make a start.

So I’ve finally started looking at this today for an hour or so.

Initial faults identified:

1) steering lock doesn’t actually lock
2) no electrics at all
3) chain and sprockets knackered
4) front brake might need a strip and rebuild.

1 was resolved by tightening the bolts on the underside of the yoke, which needed the front fairing completely off for my hands to get to them.

2 is resolved in that I found some soldering work done on the ignition switch and the main fuse had blown. Swap the...

I'll be racing my GSX1170 again , from about 1000 until 1800ish. Would be nice to see some of you there.

Not had a lot of time this summer to work on the Z as been out riding and doing other summery things but have got some things sorted out.

Among the things I would like to do for myself is media blasting parts. Have recently been given a small not working compressor which I fixed so looking to make good use of it.

Have read a lot about Soda blasting and like the idea for engine internals as the media is soluble in water. I have always had a fear that not all the other blast media will be...

Hello
I’m wondering if
Anyone can offer me any advice on classic bikes. I would like a classic looking bike up to 500cc. I have seen many online but concerned Re : repairs and parts should it require maintenance. Is it best to stick with a classic
English bike (triumph) are they easier to maintain and obtain replacement parts ?

thanks I’m advance

Hi,

I'm a new Harley convert, starting getting hip trouble so moved to a Fat Bob with forward controls, much more comfortable for me, but new riding style to get used to.

I wanted the new model Fat Bob but there were 15,000 reasons why not, so I have a 2016 model, which i'm in love with... was wondering though, would the new style rectangular led headlight be compatible with the 2016 model and does anyone know a supplier?

Not sure why I'm doing it now, other than it's something to do, and my set of carbs is missing a trumpet which saddens me.
Original carbs on the right from the 90-93 era and on the left the 94-97 era carbs to go on.

(Note the missing trumpet on the older set, which wiggled its way loose and snapped its locating tabs off somewhere on a trip to the bottom of Spain)

The later carbs are flat slide, and have a smaller gob (34mm vs 36mm) which is sad as bigger is better. Nevermind. Might make...

when do you need a battery. do you need one? the answer is simple yes. so when can I run with out one? anther simple answer. you get rid of the batterey by installing a battery eliminator.

what bikes run without a battery. duh, if you have a kickstart obviously. if your bike has an alternator you can not run without a battery. everything else is fair game. thats an awful lot of bikes. thats anything with points and a spinning magnet or any bike with cdi and a seperate lighting circuit and a...

almost any bike on planet earth can be wired to todays specs for gel batteries and led's. there are only two generic regulator rectifiers needed to do this job. one or the other will do any bike. both cost less than 15 quid.

I'll let xmacina, bender, and fastbob finish the post.

Hello there, I've been working on my bike (Honda Xl125 1983) and after it not running properly I decided to study the spark plug, its carbon fouled, and I read that it was a sign of the bike running too rich. Since then, I've installed a new air filter and checked for air leaks, which there doesn't seem to be any. I then inspected the carb to make sure the float wasn't sticking and was at the correct height, which it was and even looked to make sure the needle was positioned on the correct...

Hi guys, just been fettling around with my old bike and the time has come where I'm officially out of my depth, and think its time someone knowledgeable looked at it. I started looking for a garage around my area and there's rather slim pickings, the one I decided to go to was a bit out the way and not only did not fix my issue, but were utterly hopeless! they lost the bolts for my side panels, ripped out some of the electrics and charged me a fortune! So the question I'm asking is, does anyone...

Hi,
I am new to the forum having just picked up a barn find (genuine as been in the barn on a farm for 15 years).
It’s a real basket case as so much rust it’s going to be a real challenge to do anything.

After advice before wasting time on a pointless restoration project;
To restore it will have to be more of a rebuild as the rust and pitting is so bad there is no way it will restore to original so many parts will have to repainted to hid the mess.

With this in mind is it going to be a...

Hi, I have a 1996 CBR F3, it started coughing at 6 1/2k revs. I have replaced the ignition coils, spark plugs, fitted a new in line fuel filter and new fuel pump, I've cleaned the in tank filter, balanced the carbs and redex treated the fuel.... On the way home today it started cutting out completely. The RAC chap thought it was fuel starvation which seems right, as soon as the carbs are empty it dies. Can anyone throw some light on this please as I am now completely lost. When it's running...

Why You Need This: The original cam chain tensioner is the Achilles Heel of the Honda CL / CJ / CB360 engine; broken cam chain tensioners (sometimes called cam chain slippers) have destroyed many engines over the years. Replacement cam chain tensioners along with its matching cam chain guide from Honda are long gone. Because of this the best one could do was to find a clean used tensioner hoping that it has some life left in it. One could easily say this the single most valuable part in the...

So I have acquired a new free side project in the shape of a mini moto, completely unsure of what bike it is and what age it is but I'll be posting some pics of it on Tuesday afternoon as it's my next day off work but iv decided that it is now going to be a birthday present for my niece as she will be 3 in November and she has been asking about getting a bike for a while so it gives me some time to fully strip the bike and give it some much needed TLC thought she wants it painting bright...

About to venture into my first project;

A little 125cc bobber build.

I’m looking for a little advice on which bike I should start off with, extremely exciting times and I want to learn more.

HONDA REBEL 125
YAMAHA VIRAGO 125
HONDA SHADOW 125
AJS 125
SUZUKI GZ 125
GILERA COUGAR 125
SUZUKI MARAUDER 125
SUZUKI VL 125 INTRUDER

What would you recommend?
Easiest hardtail etc?

I don’t have the craziest amount to spend but long terms projects are worth it. Thank you in advance everyone.

How does the scoot rec/reg work. how can it be hooked up so it does not explode. I'm going to explain the how and why and when. the internal workings is a trade secret. so how do you get secret circuit diagram. do like trump and get help from the russsians.

got this diagram from the net. I will explain. the kbpc3510 two phase rectifier costs one quid. it turns ac to dc. as long as you hook it up to a dc stator you can run this way with the minus terminal as ground. a dc stator is not...

Hello
I have a 1973 Suzuki B120 which was a barn find and I have the bike running quite sweet but I cannot seem to get the main lights to work. I have cleaned all the connections and have replaced some with new. I have checked the battery and all the bulbs which are working and put in a new rectifier.
If I put the ignition to the 1st click daytime riding the indicator's work and the brake light works and so does the neutral light and indicator light. But when I put the ignition to the 2nd...

I fear not :shock:

Hello All,

I am really struggling for information. I realise that there are an awful lot of modified motorbikes around and that most of them are probably on their original reg numbers. Has anyone had any experience of using a hardtail frame and having it tested? (IVA/MSVA). I presume if a new frame then if done by the book it is likely to go on a Q plate? I presume if a hardtail is welded on to an existing frame, then there is still an issue of modification? Has anyone any experience, it seems...

I've bought a Honda VT 500 1988 and the engine is completely shot I'm struggling to find a replacement is there an alternative engine I can use or does anyone have good one for sale
Thanks Kevin

root canal and tatoos, two things better when left to pro's. I'm giving you a pass on this.

Hi Mates
I am hoping someone very knowledgeable on old Suzuki gxers can help me with trying to identify my bikes DNA.
I have owned bike since 2004. Imported to NZ from Japan in 1992.
Curious clues :
1) On ownership docs first, registered in Japan in 1987 as G model, but frame number is 101143 which makes it a 1985 F
2) Livery is Red and Black with white wheels ( signs of original blue on inside of Fairing)
3) Yoshimura 4 into 1 has numbered bracket factory fitted like limited edition but no dry...

Hi, I changed the splined kick start shaft and I can't fathom how to replace the spring. I have tried various seemingly correct positions without success.
Any help (especially a diagram or photo greatly appreciated please.
The bike's been been unused fot a few years and the clutch is not engaging such that I can't turn over the engine by pushing the bike.
Any idea why?
Thanks

there is a 2004 cg 125 advertised on fleabay It looks ok but the owner says there is a knocking noise coming from the clutch side any ideas on this one :?: could it be expensive

Hi guys, I'm new here and desperate for help.
I bought a part finished gt550 trike. It's a 1993 modul.
We can not get a spark from number 2 and 3, we have tested both coils and are both working. I have replaced the cdi unit, the pick ups, and checked the 6 pin diode with a multi meter. I have also checked all earths I can find and checked the stand switch that is no longer there so wired connected. Any other ideas??? Been at this 3 days now and travelled 400 miles picking up parts that I was...

Bought as a bare frame and lots of boxes
Engines complete at least and was running
As I didnt take it apart its a struggle to make sure each bolt is the correct one

Hoping someone on here has one and some decent pictures of it or has one stripped down a little ,fairings off etc

Cheers

Hey everyone,

I'm new here and happy to join what seems to be a lively and friendly community.
I currently have a Honda CG ES model 2008 which I have ridden for a few years now. I wanted initially to turn it into a Cafe racer style motorbike, but I realised that my model has the square frame which rises high at the back, rather than the tubular kind that seem to lend themselves to the cafe racer look.
I'm still pretty keen on the idea of making my bike more my own, changing a few things on it...

I am looking where to purchase a new lock for an original 2004 pan european top box......any help?

Hi!

My RD125LC gave up a while back. Finally got time to look into it.

Big end bearing has gone, broke up and damaged the piston too in the process.

So going to restore the engine now. But before we start buying parts, wondered if anybody had any advice on the best place to buy them. I’d rather get original or even higher quality replacement parts.

Pattern parts might be alright sometimes, but for the heart of this engine, I’d rather focus on quality.

Thanks!

Hi after some help l. I've got a ts125x with a knackered bottom end, I can get hold of a rg125 gamma bottom end and was wondering if barrel off the ts125x would fit the rg125 bottom end?
