I recently bought a new motor for my crf50 , she's an 88 mod - kitaco SE ultra head on a 88cc taky barrel.
The carb I currently have on is a mikuni VM22 22mm carb , which looks too be almost of a 2 stroke , looking at it.
Anyhow I've been having a few issue's with getting it running correctly. Basically she starts first kick cold or warm , so no starting issues but seems to only run half decent with the choke on. Throttle cracks quite good , not too much hesitation but seems to lack a little in power? But before you jump in and say its running too lean , As soon as I wack the choke of the bike begins to build revs and continue to rev its tits off. Even when the throttle is cracked it returns to reving past the moon.
I've pulled down my carb , soaked it in turps. Ran wire through the jets and cleaned the whole thing out. Still nothing , just revs to the moon once that choke is off. I tried riding it like so and it just cuts out or hesitates. I've checked the throttle cable , its fine. The pipe on the old bike was 32mm and I run a 28mm ID pipe if it makes a difference and a uni pod filter
Would anyone be able to please point me in the right direction as to what may be the issue?
I've checked for leaks , resealed bowl with silicon .....
No exhaust leaks
Its not a 'reversed choke either'. It doesnt start cold without it being on the choke
Cheers
