And all of the intake valves had a clearance of 0.006. Each measurement was recorded when the feeler would go in with a little effort and I could feel it grab on the way back out. The next size feeler (0.011 and o.007) could not be inserted. All measurements were within spec. For anyone attempting to do this themselves it wans't too difficult. The biggest problem was removing enough to easilly get at the cams! I removed both front side panels the left side panel the tank, the airbox, and the bracket at the very front of the compartment that routes the throttle cables and holds some electical doohickies.... I also disconnected the throttle cables to make room to remove the front valve cover. Only one bolt was difficult to get to, the front left one on the front cylinder. I was able to loosen it from the front of the bike (through the gap between the radiator and the frame) and then remove it from the top like all the others. I was able to get the cams in the correct position by putting the bike in top gear and rotating the rear wheel (thanks Ian). Everything buttoned up pretty easilly, except the airboox. I first connected all the hoses and then tried to get it in the right place; no go... I then pulled the hoses back off and loosened the front bracket and got her into place with only minor effort. We went for a ride and all is well. I'm definitely glad I did it. I feel so much closer to her now....,I had 9700 on the clock. Almost all of my miles are commuting, but I've got a good mix of backroads and superslab... As far as riding style, I'm a gentle rider. I mostly shift around 5k rpm and only rarely bring it up to redline. I'm always amazed at how much I can enjoy riding without really pushing it! With that said, last night I had a minor accident on the way home.... The results of that I'll post in another thread.,,,

How adjust valve clearance


guys mainly the valve gets heated and gets expand so the valve clearance is adjusted . according to my studied knowledge the inlet valve clearance should be perfectly 0.5 mm and the exhaust port must be 0.6 to 0.7 mm. this the perfect tuning for the 2 wheelers . [ remember guys before you set valve clearance make sure that engine is fully cooled condition.....

Exhaust blows and sucks when turned over on trx300 Honda Fourtrax atv. What's likely the problem? I suspect something to do with the valves, perhaps a top end rebuild or just new top end gasket and o-ring...


Hi and welcome to FixYa. I am Kelly
The exhaust valve is remaining open. This can be caused by carbon stuck under the valve tapered head area, a cracked valve seat or..... a broken valve spring. NOT head gasket. Before you take the head off.. open the valve cover and check for a spring problem. If there does not appear the be a spring problem watch the valve travel and then make sure with the piston at the top of cylinder that the rocker arm has 0.003 - 0.005 clearance between the tappet and the end of the valve.
If there is no clearance adjust the tappet clearance.
After you have the proper valve clearance check for the previous symptom. If you still have that symptom then your going to hae to remove the head and inspect the valve tapered area and valve seat for carbon, cracks and abnormal wear.

Thanks for choosing FixYa.

I have a 06 yfz 450 that is very hard to start how do you adjust the valves


You need to remove the valve cover and rotate the crank shaft to TDC then with a feeler gauge you check the clearance between the cam lobe and lifter bucket. There are 3 on intake cam and 2 on the exhaust. The clearance will most likely tighten as the valve seats and valve wear in. If the valve clearance gets too tight they will hang open and not seal for proper combustion. Valve clearance for my 2002 YZ426 are intake=0.10-0.15 mm (0.0039-0.0059 in) exhaust=0.20-0.25 mm (0.0079-0.0098 in) the 450 should be the same or very close

Apparently the valves on a 83 1100 wing need adjustment every 10,000 kms, how do i do this? thank you


The correct valve tappet clearance is .004" on both the intake and exhaust valves (cold engine).

Remove both valve covers. Remove the round timing inspection cover from the top left hand side of the crankcase. On the rear of the engine, on the left side, is another round cover to remove - this gives you access to the head of a bolt on the end of the generator shaft (use a 17mm wrench to remove the cover).

Using a 12mm box end wrench, turn the generator bolt clockwise until the "T-1" mark on the flywheel is aligned with the notch in the timing hole. Now, check the valves for the #1 cylinder (the left front cyl.) - both should be closed and their cam lobes facing in, away from the rocker arms. If not, rotate the engine another 360 degrees. Check both valves for the #1 cylinder with the .004" feeler gauge. The correct adjustment is when you feel a slight drag on the gauge. Use the lock nut and adjusting screw to set the proper clearance. At this time, you may also adjust the #4 cyl. intake valve and the #3 cyl. exhaust valve.

Next, rotate the engine another 360 degrees, aligning the "T-1" mark again. Now you can check / adjust both valves for the #2 cyl. and the #3 intake, and #4 exhaust. Then, you're done.
