[QUOTE="jimt_yz400, post: 1253938, member: 21081"] Hello Dirtrider friends! :) I haven't posted for a very long time but I thought I would toss a problem out to you all. I have replaced valves many times in the many CRF450's that I've owned but I thought that I would give the Kibble Whites a go this last time around. The guides were in great shape and I had the seats cut for the new valves. I assembled the head myself. Everything went together fine and I adjusted the valve clearance, we had to use larger shims for all valves (for example 210 to 235 on one of the exhaust valves, I didn't think this was a big deal). It's very hard to kick over; it runs like a raped ape though! I checked the compression release clearance and if I read the manual, while at TDC, valve clearance + .014 = compression release clearance: ie: .012+.014 = .026 so the compression release should be .026 in. That is what the clearance is, .026. I checked the alignment of the cam and it is right where it should be ( I have had the cam in one tooth retarted and it was difficult to kick over, but had lots of low end! ). With these valves is the kick over to start the same as it would be with the stock valves? Is the stiffer valve springs causing this? Am I not measuring the compression release correctly? Thx in advance! Cheers! [/QUOTE]
