mikuni carb settings?

Tombstone · 04-26-2013, 12:55 AM

Hey guys,

I found out my bro screwed all the screws back in tight when he cleaned his carb and that's probably part of why it wouldn't start worth a crap. Does anyone know the factory settings on the air and idle screws for mikuni carbs?

thanks!

I would turn them out 1.5 to 2 turns each and start from there. It should run with those settings.

Weld will be able to help more.

That's where I would start.

After it's running, reset the idle to a sane RPM, and then quickly open the throttle, noting if there is a bog or flat spot. If there is, adjust the pilot mixture screw 1/4 turn at a time, ideally not backing it out more than 2 turns.

If there is no bog, enjoy.

hey guys im going to order a new makuni carb for my bike but im not sure which one to get, its the lifan 200cc motor in mine (if you remember an old thread on my bike being less powerfull than my bros), can you provide a link to the right carb on ebay or give some advice on how to figure out which one to get? They seem to have a few in slightly different sizes. thanks!
