Can anyone with autoelectrical knowledge tell me why the HT leads on a VTR1000 would have a braided earth wire "appearing " from half way along the lead (from under a sheath for the want of a better word , but like an extra length of outer heatshrink ) and then running to an earth on the frame ?
Is this some sort of electrical suppressor ?
The whole idea of a possible earth strap connected to the HT lead has me wondering why they exist at all....the idea is to get all the charge to the plug...
Surely this could be a potential point for a misfire problem I have - the bike runs fine to 5k, and then acts like it has hit the rev limiter...
It is NOT carbs - been right trhough them 3 times .....in fact have it jetted so well from start to 5k..

hi there im new to the forum but i have had a similar problem recently, like yourself i checked everything and eventualy found it was the fuel tap dyaphram split. take the tank off then empty the fuel out, take off the fuel tap and undo the 4 screws on the vacum tap,beware of the spring inside, check the rubber to see if u have any splits in it.
what happens is it will not draw enough fuel when the revs are high,that could beyour problem.
hope this helps.
