I just encountered the first real problem on the 640E, at 22000 miles the exhaust valve/valves are sticking open. This causes a loss of compression and poor performance. Is there any way to fix this without pulling the head?

Check your valve clearances. Could be varnish build up from bad gas. Depends on what they're getting hung up on. Could be time for new valves... Just a few guesses.

Is there a bike made of late, say the last 3 years that is like the 640e but better? 690 looks sweet but I sure read about a lot of horror stories with them? IMO my 640e is the best all around bike ever made. FOR ME.

Looking too :-))...
But so far all the 690 stories I ear and see on the 6x 690 I ride with are more maintenance items ... New items for efi bike.. Have you tried adjusting the carb on a 640 if you didn't know what you were doing or had other to help?

Weather or not you can fix it without removing the head really shouldn't be the question. At 22k miles you really should freshen up the top end on the LC4. Just because you love it that much. There are a few documented cam and cam follower bearing failures in the index and they seem to happen right around this mileage. When they go, it's not pretty. It really is time for a top end fluff n buff. How about the water pump seals and impellar? It's time. What year is your bike? Does it have the suspect clutch side main bearing? If it does and it hasen't been changed, it's time. Take care of the ole boy.

Yes I have my bike tuned really well. I think I got lucky. Followed all the great advice on hear and my bike flat out rips. Last bike I owned was a 87 kx 500. So I was afraid the 640e wouldnt have enough balls. I was very wrong. I would just like something newer so chit dont start fallin apart while I have it still. All old machines start breaking down at some point and I hate dealing with old bikes that keep fallin apart. So far mine dosn't.

It is MRA Roadshield. It works great. Adjusts from the saddle, blocks the wind blast, doesn't effect handling, and comes off by loosening two bolts.
