I just got the bike for a really good price but really don't know much about it if someone has any past experience tips they could share I'd really appreciate it! Also I can't seem to get it to completely fire. It has spark, the carb is full of gas, the reeds look good, but I'm not getting fuel to the spark plug. I'm our of ideas besides maybe top end, but I don't want to spend 100-?? On it if there's things I should check first. I know it doesn't seem to have as much compression as a 400 should. But again I'm new to these bikes. Thanks in advance!
