optimum temp to adjust valves By tvnacman (Read 789 times)

Good morning
So this is my question ,I have had my bike at work and it is heated about 70 degrees the bike started soso . yesterday it was mid 30's out side and the b ike was outside and I tried to start it, did not start (I didn't want to fight with it )

so should I adjust the valves in 30 degrees cold , or would it be better to adjust the bike cold in 70 degrees ?

Being that I have the choice of temp I'm just looking to do what would be best .

If I adjust in the cold and it starts up well I reap the fruits of my labor .
I have a feeling it might be the carb causing the problem , however the scooter has 2200 clicks on it and I have not adjusted the valves .

Hey John, if you've never adjusted the valves it needs to be done. They can cause a host of problems. We've got a valve tutorial in the engine tech section. I've always adjusted mine in the basement, about 70 degrees I guess, I wouldn't freeze your nards off outside adjusting them, I don't think it would help. Do one thing at a time or you don't know what fixes what. So adjust the valves and if that doesn't cut it get back with us. Rich

Yes, outside temp wise doesn't matter as long as the engine is cold. When engine is hot after running it the metal expands and you will not get a true valve gap mesurement. So by all means bring it into where it is not freezing so you don't get frost bite on your fingers and hands.

70 or 30 degrees makes no difference as long as engine is cold. Save fingers do it inside.

Cold engine overnight or at least 6 hours after it has been run...
