'06 MC65 bogged acceleration from low RPMs

[cajones007]

All,

I recently bought an MC65 for my son and he is having an extrememly difficult time accelerating from low end RPMs - the bike bogs and he has to lighten up on the throttle.

In my discussions with a few 2-stroke bike owners, it was suggested that I move the needle up in order to dump more fuel on the low end. Unfortuntely, this didn't help. I thought I might need to adjust the air fuel mixture, but can't find any settings (specs) for the carb.

The bike startes easily, the plug appears to burning clean and haven't had an issue with fouling plugs. I pulled the carb, cleaned it thoroughly, but still have the same throttle issue. I have become very frustrated in troubleshooting this issue and thought it would be useful to see if anyone else might have some insight to share. I look forward to hearing your feedback and sugestions.

Chris
