Title: Diagnostic Question
Post by: DocFree on April 22, 2007, 11:09:54 AM
Bike starts fine and runs strong.. until you give it gas form a stop.  While holding the throttle in, the rpms will go up, then suddenly drop to almost stalling, and then kinda catch again and rpms go back up.  Is this a carburator problem?  Does this even with cluth completly pulled in and never engaged, just by reving engine.  Its like it is flooding/bogging down?

Thanks all.

could be a couple of things.  Somewhere along the way have you cleaned the carbs??  If not do so and be very careful there are a few very small o-rings that will drastically reduce performance if not replaced :thumb:  If so, check to make sure that the o-rings under the vacuum cap attached to the slide cap are there. :thumb:

Or you could be running ultra mega super lean :o

I've never cleaned the carbs.  I guess this is the problem so I'll start there.  THanks for the info!

Could be igniton too. Replace the sperk plugs when you clean the carbs. It could also be wires or coils but those are more expensive, so start with a carb clean and new plugs
