Have you carefully compared the total stack height ?

About 0.5mm difference, i put this down to the plates wearing down. Thanks Bob!

Are you staying with the 3 long and 3 short springs or going for 6 long?
The bag came with 3 of each as the original one, is there any gain with going with 6 long?

The 6 long should give you a cleaner gear change ,less chance of clutch slip, downside is a stiffer lever, but you can always swap them back if you dont like the action

stiffer lever ay? I'm all ears :wink:

Joking aside, that sounds much better. It was the weaker lever that made me think there was an issue in the first place. Thank you :lol:

Since it's your bike and your money only you can choose whether to sell it, restore it, or modify it.

If it was mine I would try to keep it as original as possible, while replacing or restoring anything that's looking tired. I wouldn't recommend going down the streetfighter of cafe routes as crashed bikes often go that way - puts me off buying one.

Whatever you decide, good luck with it.
Might be worth keeping a diary/photo record of everything you do, for a future owner, and I'm sure the guys here would be interested in seeing the project as it progresses

I have a very tatty TDM same age as yours which I'll try to restore over the next year
I echo your sentiment, it is well put. :thumb:

The T'cat has been left as the last post on it with the new pressure plates soaking in oil for around 2 months. :lol: :lol: They should be more than ready to go on now!

I have been trying to find/borrow a torque wrench that went low enough to reach the 8nm needed to torque the clutch bolts in but @Stu recommended on another thread to chin the torque wrench off and just nip them which is exactly what I did. Thanks very much for that @Stu! Hopefully will be on the road a little sooner now.

A worry I had about not torquing the bolts in was them shaking loose but @Ian Frog suggested to locktite the screws to stop this happening. Thanks again Ian!

Luckily the bolts just came to a natural stop so i gave it another 8th of a turn in an opposing pattern so as to not stress the plate unevenly and put the cover plate on! The gasket was still good so I cleaned it up and put it back on with some military grade insta-gasket. Bodge job I know, but if that stuff stops Tornado's leaking, it should be fine on the bike.

The next cease of play is a leak i have discovered on my fork seals. I had the seals done the tail end of summer and although the bike has done 1.4 miles since then (literally the journey home), it seems they are leaking again. Doh! :scratch: :scratch:

Thats all for tonight, I did want to get it up and running, fairing back on and so on but I cant be bothered tonight. Kind of dis-heartened buy the leak which has p***ed all over my break pads meaning they need replacing and ready for a shower and bed.

Tbh with torque settings that low might aswell just do them till they seat with a normal ratchet and tweak it just a smidge it won't do them any harm
Its better when its loaded

Well it's ok for bolts that require torque settings between them figures, think the person who said that was having you on

I agree with #skyrider in general with torque wrenches the narrower the range the more accurate they are.
A sweeping generalisation I know but it applies to quite a few gauges and tools.
Cheers
Ian

It's been a while but here goes:

I put everything clutch and body-wise back together, was so focused I didn't get any photo's but never mind, you all are fully aware what a motorbikes looks like :lol: :lol:

One of the things I hate about the T'cat is the huge rear light sticking out like a spare dick at a wedding and although i had found evidence of some guides on a tail tuck on an inferior forum, it was from so long ago it had been removed. I decided it couldn't be that hard so I took the tail light off and there was what seemed to be an after thought put on by Yamaha. The light was mounted on some sort of cradle adaptor which isn't too clear in the pics but was held in by 6 spot welds. I had a go at drilling these out but due to not having a pillar drill or sufficient vice, them being at a funny angle, me being a bellend and a whole host of other factors this didn't work well and I managed to break 2 brand new drill bits so i hack sawed it off instead. I removed the rubber grommets and screwed the light fittings and grommets into what seemed like the original holes from before. This had the effect of bringing the light more into the body of the bike. I have checked and the white number-plate light still illuminates the number plate so I can only presume the reason Yamaha did it was for night visibility from the side. I don't really do much night riding so this wasn't something that bothered me.

On final assembly of the fuel tank, i noticed a cold wet hand and a strong smell of petrol. Sure enough the small U-bend pipe that goes rear-wards from the fuel tap switch thing, forwards onto the fuel filter had split. Quick trip to euro part then!

I fitted that and thats all I can really do for now! The suspected brake pipe split on the right of the front wheel looks to be a fork seal which is a pain in the ass as these were only changed in June around 50 miles ago :shock: :shock:

Ive got the guy who done them coming to look as there looks to be some very light pitting on the stantion so i may be having to buy two of these as well as another set of forkseals, then its MOT time and back out on the road FINALLY!!!!!
