BigHeavy1095 Posted April 12, 2018 Share Posted April 12, 2018 are you running the standard airbox and filter or an open filter? it may be that water is getting into the air filter? that or its getting under the spark plug cap. that's what Im thinking anyway. Im sure somebody more knowledgable will be along soon. Quote Link to comment Share on other sites More sharing options...
Deano1345 Posted April 12, 2018 Author Share Posted April 12, 2018 Yes it's standard airbox and filter I went out In the rain and it died wouldn't start again i had to take spark plug out get petrol in a syringe and put it in the head the bike started and like I said it runs perfectly in the dry but bogs in the wet Quote Link to comment Share on other sites More sharing options...
Six30 Posted April 12, 2018 Share Posted April 12, 2018 Spark plug cap , water getting in . Quote Link to comment Share on other sites More sharing options...
Deano1345 Posted April 12, 2018 Author Share Posted April 12, 2018 How would I sort it to see if it is that as the spark plug is in nicely Quote Link to comment Share on other sites More sharing options...
Fozzie Posted April 12, 2018 Share Posted April 12, 2018 Fender extender to stop it throwing up water all over the engine.Also, with the HT lead on, apply a layer of silicone grease around the top of the sparkplug/cap/HT wire. Stops water penetrating in. My SV650 used to frequently become an SV325 when the front cylinder dropped out. The method above stopped it ever happening again.
