Hi Guys,
Getting near to the end of stripping the current project.
Electrics are shot so I haven’t been able to start the motor, however I have managed to get the starter motor to turn the engine over. Compression test are low ~60psi across all cylinders. The pressure goes up to ~125psi when oil is added to the cylinder.
Low values could be due to motor still idle for years, cold test and cheap compression tester.
Also the cam chain tensioner set bolt is broken. I have no history about the bike so I’m assuming the worst engine wise.
Next step:
1. Fix cam chain tension set bolt - do nothing else and get the engine running
2. Do a top end rebuild, possibly with a 466 kit and install new cam chain
3. Do a complete engine rebuild
I’m taking the approach of test, research and repeat before splitting the engine for my first rebuild. I welcome your thoughts on what would be next step that is sensible.
The rolling stock is solid but rough. But the front end has been changed to a cb250n. I have sourced hubs and forks from the USA and will return to stock wheels.
So while deciding on the engine component I have much to do on the rolling stock.
Thank you in advance
David
