Default CR125 bogging


My 1994 Honda CR125R has a weird problem. before i put it away for the winter it started to make a weird bogging noise in every gear when i try to hit powerband. it starts to break up and bog right down. But when it idles u can rev it up and it wont break up. Help me out!

Default ???

How old is the top end?
Have you done a compression check?
Is your gas /fuel mixture fresh?
How old is the spark plug?
What does the spark plug look like?

anytime you want to ask a question on why your bikes engine is performing, always include the answer to Paw's 5th question. the pj carburetor that comes on those is problematic, especially as it ages. yours ir probably running rich, and if it is a progressive thing as it sounds it can be the float. all it may need to run better is the float to be adjusted.

there is a great post in the knowledge base here on atm by faded with a great pictorial that applies well to your carburetor. setting one is "free", and where I would start. you may be able to get some hours of riding before you start spending money on some of the rest of the items on that list!!
