Dead Curvy
 

Ok Ok so I sold the twin and have gone back to an in line 4 but I am after some help.

A mate asked me to check out his SV that wasnt running correctly (i was an auto electrician in a previous life). It seems that I may have dropped myself in at the deepend as he has heavily modified the bike and nothing seems standard!

Anyway, the main problem is that the bike fails to start 9 out of 10 times and when it does run, back fires badly with no revs or power .

The carbs have been checked and cleaned, all ignition circuits checked inc coils. I did find some "cut wires" where the owner said the ignition retarder was and that it had been disconnected.

The other issues that I discovered was that there is electrical current running through the frame of the bike. Looking for ashort circuit I discovered a very small amount of current going through the "meter" fuse with the bike switched off and key out of the ignition. Although a fault I fail to see if this could affect the running of the bike. I am inclined to think that the actual ignition switch is the main culprit but have yet to check it out.

Any other suggestions more than welcome!!

Cheers

Check the wiring loom on the rear subframe they have a tendancy to wear through there!

Thanks Billy, will have a look

The meter fuse runs the clocks to keep the trip meter memory so a small current (how small are we talking?) doesn't really suprise.

When it's running badly, just gob on the downpipes to check they're both running. Run it for a bit, then take a look at the plugs.

Yeah check plugs. Is there any chance the HT leads are on the wrong way around?

No. Rear one won't reach the front plug.
