Okay confused. .. So I adjusted the exhaust at .008 and the intake at .004 and now the valves are clicking quite a bit. The exhaust was loose previously and the intake was tight. Have 9500 miles on the bike. Just want to be sure they are supposed to click or knock. Just dosent seem right...

Also if there's anyone in Vegas that knows what they are doing and wants to give me a hand or just make sure they are right, please let me know.

Thank you in advance!

Unless you are using an angled feeler gauge I suspect that the gaps are slightly larger than you intended. The straight feeler gauges tend to give you larger gaps than the actual width of the gauge. You can try re-gaping the exhaust closer to the upper limit and the inlet valves towards the lower limit. You can try bending the end of the straight feeler gauge for easier use, caution, it may break. If you are sure that the gaps are within limits then a light tapping sound is acceptable. However if there is no tapping then the valves may be too tight. Better to have a light tapping than none at all. Getting an experienced owner in the Vegas area is a good idea if still unsure.

The feelers are indeed angeled. They are from P.C. I made sure the valves were in the correct position beforehand and lightly tightened them against the feeler,then snugged the lock nut. After which both fit just right. It just seems the knocking is a little excessive considering there was no noise beforehand. I would hate to run the bike and burn out a valve due to improperly adjusted valves. Especially with what life this beauty still has. ...

Thanks for the input!

If you are sure that you set the clearances correctly then just accept that the tapping noise is normal. I would only be worried if the tapping noise was absent. You can still get someone close to you to check the clearances and also compare his engine noise with yours. Maybe the previous clearances were too tight..!!

Great thread. I just checked the valves at 700 miles. ProCycle angled feelers are easy to use. No adjustment necessary.

I checked valves at 750 miles, first time, and did not need to adjust. I just checked them again with 3350 miles and they are still in the middle or upper end of range. One side of intake the .005 feeler goes in with a little resistance and the other side, the .006 gauge goes in with the same resistance. Both the exhaust take the .008 gauge with little resistance, I think one side would take a .009 gauge with some resistance. I'm using the PC bent feeler gauges. Is this normal, to basically have no valve clearance change in 3350 miles? I will check again at 5000 miles.

Normal.

OTTOMH, mine have only been adjusted maybe twice in almost 70,000 kms

You will only burn out a valve if the clearances are too close. Set the clearances to the middle of their tolerances and you're good to go without a worry.
