Bike took longer to warm up. Only ran smooth with choke one quarter out. it's running fine,then just quits. start it but won't take throttle. finally starts,but sounds like itis only hitting on one cylinder. PLUGS?

Answer
Hi Larry,

It's difficult to accurately diagnose the problem with the information provided, respectfully.

The spark plug(s) are likely fouling. The reason for fouling needs to be investigated.

If the engine starts and runs with choke, but stalls or runs poorly without choke after a reasonable warm-up period; indicates the carbs pilot circuits are obstructed and the carbs needs thoroughly cleaned.

I return tech information files by email. There was no email address with your question as requested and explained in my instructions.

Respectfully,
