Diagnose this please doctor..

Hi guys. I was wondering if you can help me with an intermittent problem i have with my storm. When its raining it seems to just start cutting out, seems like its only running on one cylinder but both seemed to be firing. It misfires like a mother and generally misbehaves.

The only thing is last time it happened it cut out, locked up and highsided me down a dual carriageway. Which was nice. So i cant really begin testing it too much. Iv started rebuilding it so i just need somewhere to start looking. Many thanks in advance.

Water getting into the front coil/spark plug cap

[AndyEames]

Yeah seemed to be to me aswell. Was going to change both coils leads and plugs aswell just to try and get rid of that possibility. Just gathering ideas just in case its something i hadnt thought of.

Front plug drain hole could be blocked!

[AndyEames]

Which drain plug? On the front cylinder?

It's not a drain plug, it a drainage hole on the front cylinder for the spark plug, see link:-

Ah right i see. I shall clear that out aswell. Thanks guys, this is why this forum is awesome! Could there be any fuelling or air issue in the wet?

[tony.mon]

No, these are both closed systems and so water can't get n.
It's just sparks that can be affected.

Good stuff thanks guys. Ill do that and let you know the outcome. Whilst im here have you guys got any tips for taking the swinging arm out as the crash broke my rearset (brake lever side) so not really sure how to secure the bike whilst i take it out. Got nothing to hang it from in my garage.

If you have a spare axle or swingarm bolt. They are both the same diameter but one is shorter than the other very slightly (cant remember which, Swingarm bolt a tad longer I think), knock that through pushing the bolt out and keeping the swingarm in place and do what you have to do. Then knock the bolt back through the other way pushing the bolt back in and other one back out. Don't forget to put the right hand side rearset through the bolt before knocking it back through You can do all this while on the sidestand if you wish.

Thats a great idea. Never thought of that! Every day is a lesson. Appreciate that dude!
