Help Tuning, no idle
Kfan:
Years ago I had a smaller bike with the same problem. It ended up being the needle jet, which is the brass insert that the needle runs in. It came as a kit with a new needle. The guy at the bike shop told me that fouled plugs and poor low speed idle when cold were almost always corrected with this repair. I hope this helps...

Tried cleaning up the seat but it made no difference. Ordered a used carb body to try and see if things are any different. Trying to keep it cheap till I figure out what exactly I need. At the point where im thinking carb but could be ignition. If ignition I will get the PVL that can run lights. If carb, im thinking 38 air striker..

Problem has been fixed. The other carb body did the tick. Still a little stumped on what the issue is but am just glad its done. I plan on taking a test ride tomorrow night, I expect everything should be good. Next project is making it street legal. :mrgreen:

good to hear.
I would lean towards the needle seat being worn...but without actually being able to look at it, I really can't say.

Test ride went pretty good, no motor problems. Felt a tad flat on top, gonna go up a main. Hate my tires, and the 110 rear is way to skinny for this kind of power. Forks felt a little harsh over rocks and such, much better on bigger hits. Need to find a better clutch lever. The MSR AOF still gets hard to pull. The big stuff is done, just needs some fine tuning.
