45cc guys, check your head bolts...

Pulled the head on my 45cc and the head bolts were not tight at all. Very easy to remove. Going to put a single ring piston in it.

Not an expert by any stretch but think they should have been tighter then they were.

It's a rovan bro. Don't expect good quality control. I had a buddy with the 45. It didn't last 8 or 9 tanks before the case let something out.

Both my 45s have been good so far, knock on wood. Even with the bolts not very tight she was running good. Checked my other 45 and they are good to go so far.

Time will tell.
