I guess I got lucky. Mrs. 2LZ brings me another beer at 9:30 pm and hands me wrenches. ;-)

At 9:30 my wife starts to hit me with wrenches if I am still in the garage

.07 mm isn't much but nil is even less and nil is what my valves measured after 500 miles. I would be surprised if nil isn't good enough. It ran just fine at nil and I only checked the valve clearance because the manual said to check them not because of any ride-ability problems.

.07MM isn't much, but it's enough. With no gap, there's no oil on the mated surfaces like cam-to-pushrod. Could cause scorching issues.

Does anyone know the thickness of the TT250 handlebars? Are they 7/8th?

yes, or 22mm

Has anyone tried an OEM exhaust from a CRF230 or something else from Japan? I'm aware of the Chinese "CRF230" aftermarket from Ebay but has anyone actually tried OEM headers designed for the Japanese bikes?

Yes, 2LZ, you are right. And even worse is the rocker arm valve interface. Especially on the exhaust side. The exhaust valve stem runs very hot, and needs oil to carry away some of the heat and prevent galling of the rocker arm pad and/or the valve top.

Yes I've installed a Pro-circuit t-4 on my Hawk,the same one for the 2007 crf230L,it sounds amazing.Had to do the same light modifications as everyone that used the ebay one.

Congratulations to both of you on the 22 years of marriage. Not all that common, these days.

This is a known problem. My prototype clusters read fast as well. The MFG says this is common practice in China for "safety" I actually had to make them calibrate it properly and now we are 1mph + -
