Am I correct? and stupid

Recommended Posts

Hey

I am calculating which new shims to use. Can someone tell me if I am right.

Desired clearance = .006 +/- .001

Left intake : .002 / .051mm

Shim : 2.22mm

new shim : pn. 14937-MBB-00.... .0827in / 2.1mm

Right intake: .003 / .076mm

Shim : 2.2mm

new shim : pn. 14937-MBB-00.... .0827in / 2.1mm

Desired clearance = .011 +/- .001

Left exhaust: .014 / .356mm

Shim : 2.13mm

new shim : pn. 14941-MBB-00.... .0866in / 2.2mm

Desired clearance = .011 +/- .001

right exhaust: .013 / .330mm

Shim : 2.14mm

new shim : pn. 14941-MBB-00.... .0866in / 2.2mm

The bike is an 03 crf450 and I put the ss KW valves in before last season. I am a little disappointed that they have lost some clearance but maybe they have seated now. It looks like the exhaust valves shrank.

Any help and susgestoins would be great.

Aslo I learned a valuable leason. When changing the Cam chain make sure you hold onto it tight when removing the fly wheel. I cracked the case cause it got jammed against the thing that holds the chain slider beside the crank. $380 or a weld job and some new bearings/seals later and I feel like an idiot. :cry:

Should I make the intakes a little more loose. I heard something about tighter is better. But I am not sure that applies

I think the case is to be welded today. I feel like an A$$. Try explaining to your wife you need to spend more money on your reliable four stroke. I used that angle to convince her to let me buy the bike but now I look like a lier. I smell more foot rubs. :cry::cry::cry:

thanks Fred but it was sold.

I am suprised my kw ss valves went lost clearance? Is it normal?

From what I've read it's normal to lose a few thousandths as they seat in.
