I recently purchased a running '04 Honda CR125 at the right price. The bike can easily bump start, almost too easily but it's a bear to get it to kick start. I'm getting 30 PSI on compression test and understand that's extremely low. Where do I need to start looking as I bought the bike with the top and bottom "recently rebuilt." But we all know recent is relative. Could the powervalve be the issue? No smoke and it's spitting a little, just need to dial the carb in. Also, anyone done the Keihin PWK Airstriker carb conversion for this bike? The gears aren't shifting as smoothly as I would like and the clutch isn't smooth either. Where do I need to start looking for a hopeful easy fix? I recently graduated from college and got back into bikes from when I was a kid, seems I almost enjoy working on them as much as riding. Thanks to @adnohguy's advice I ordered a service manual for the bike. That is a huge help but sometimes TT can't be beat. Thanks for any advice offered.
