does it stink of fuel out the back? sounds like it could be a stuck float.

Default Re: k2 curvy running problem

right have spent the last few hours looking over the bike and think i might have got it.

when i have the bike running holding the revs at around 2.5k to stop it from stalling there is a sound that comes from the front carb on the front head that sounds like blowing air (is there only way i can explain it)

so i am ever losing compression at the spark plug or leaking around the head .... but then again mabey not as there is no oil ec.

the nosie also sounds like it is coming from the front carb so i have had them off the bike and looking over them i found this.





this is were the choke goes into the front carb as you can see the mount is broken do you think this has anything to do with the problem i am having? as the choke could always be on meaning its throwing to much fuel in ?

also as you can see i F****D the screws to try and undo them i still have not got them undone

You need to learn how to undo stubborn screws.

chokes are a possibility. While you have carb off take float bowls off and check for crap.

could be stuck float giving too much fuel, are the plugs wet?

or it could be a blocked jet giving not enough. Just generally look over the carbs, is there loads of carbon deposit on the backs of the butterflys?

So many curvy running issues are down to dodgy choke plungers.You need to get that mullered screw out and check the innards.And the other cylinder.
