Recently got a new stator and regulator. It starts and runs, but...

When it is running it won't idle. The rpm's just drop and it stalls. I have to choke it to get it to refire. It seems to run well in the 4000K + rpm range, but anything less and it bogs when given gas. Is it a carb issue?[/align]

 

checked the gas lines and everything seems good. took it for a spin and it almost sounds like it is a twin until you hit the gas... 2-4 second delay... then bang. it sounds right and has the power. is it out of sync? need a carb tune?

 

Has the bike been sitting for a while? If the bike doesnt idle well, but works good after 4k, then id assume is the pilot circuit of the carbs. it would be a good idea to open up the float bowls, unscrew the pilot jets as well as the mixture screws and give that circuit a good cleaning. I had the same problem till last night and this is what i did to fix it. You should be able to see right through the pilot screws.
Have you tried simply adjusting the idle to see if that will help? Also, a carb sync wouldnt hurt.

 

It is running better today. I'll try to force a little air throught the top side sometime. The last person to clean the carbs didn't put back the idle adjustment screw (damn!), so until I take them off again I don't have that control. It is definitely idling too low (700 RPM, should be 1000-1500). Friend/mechanic rode it today and said it seem to be in sync, so it must be the jetting, etc. I'll let you know if I find anything else, but thanks for the suggestions.

 

any news yet? sounds like mine.

 

just needed to run some good gas through the system. It runs much better now. Probably will have some tweaking done to the carbs next spring.
