Bike starts on choke revs up

Post by Steven_G22 » Tue Sep 20, 2016 4:51 pm

Hi hope someone can give me an idea where to start with the problem I'm having!

So the bike starts up on the choke but then revs right up to about 4000rpm then when I turn the choke of the bike will cut out!
I'm not quite sure where to start just checking if anyone else has experienced anything like this

I'm having this issue as well. I cleaned the carbs, reset to factory setting and , the most useful part, imo, I balanced them.

It didn't fix all my issues but it made the bike useable so I could start trying to fix it.

Also check for air leaks around the inlet rubbers. I replaced them and the o-rings as a matter of course.
