OHC owners beware!
I checked my valve clearances today (15k miles), I found they'd closed up to near zero. Last checked and adjusted at 7.5k miles.

Hot, or cold?
Hot.....they are supposed to be near 0. Cold.....I can't imagine it running worth crap hot. |

If you are new to these valve adjustments It is hard to tell if they are tight or not. It is not easy to get that flimsy feeler in there!

On the pushrod engines the valve lash increases as the engine heats up, thus the very tight clearance adjustment. Is it possible that the OHC engines do the same? Would be interesting to compare the hot vs. cold clearances.

No offense taken, But my comments are still accurate and many of us here need all the help we can get. We are glad to have someone who has been at it for 29 years.

I might just be imagining things but she seems happier at higher speed, I also changed the DR8EA for a cooler running DR9EA as she has to work hard in my hands!

I find this a lot on Chinese engines. I've maintained a lot of bikes and the valve clearances have always got bigger, not smaller with time and mileage.
I feel the Chinese alloy casting maybe softer and there's a certain amount of valve seat settlement or "recession". This closes up valve clearances and is the source of lots of trouble on these engines. Just check out other forums...:) http://www.telecable.es/personales/a...trecession.png |
