What a pain in the rear to get to the exhaust valves. When I finally got everything stripped down, they did need some attention. Both exhaust were a very tight .013. I had to really force them to take a .013 feeler gauge. I loosened them up a tad. The right intake was a little loose at .009 which is supposed to .006. The left intake was very tight. I could not force a .006 under it. I didn't have anything smaller to actually check what the clearance was. Reset both intakes to .006. Haven't ridden it but don't expect any noticeable difference. But I am glad I checked them and caught the tight intake one. At least now I know they are set to specs.

Please let me know if your adjustments made a difference in anything, because I am really thinking about getting my valves checked. How many miles did you have when you checked the valvles? Is 200 miles to early?

 

[dickmadison]

Jason, I think the book calls for them to be inspected at 100 and 600 miles. I have 293 on mine and 38 hrs. I am glad I checked them and found the one that was too tight. I just want to keep things up in hopes of keeping my extended warranty in effect. If you need anything else, please let me know.

I've been checking my valves roughly every third oil change. And since I have about 15 hours on the current oil, I will probably check 'em again at the next change in another 15 hours.

I currently have about 1200 miles on the machine, but I'm not sure about hours.

Sorry this is kinda off-topic...
Rob, you still having that top end problem?

 

[RobG]

Yep, no change. Haven't been modivated to try to get the dealer to do anything with it. I will either do a webcam and hotshot box (when it comes out), or sell it... but neither is likely to happen before Summer anyway.

How do you tell intake vs outake?

 

[bvstone]

I just adjusted mine at 600 miles. Intakes were loose (could fit .20mm in there) and exhaust was spot on.

I noticed a small improvement in power after adjustment. It's a little tight to get the feelers in, but other than that the adjustments are a piece of cake.

Saltybeagle, the intake valves are towards the back of the bike. The exhaust valves are towards the front.

 

[Saltybeagle]

Guess it only makes sense since the air intake is in the back and the exhaust is in the front, DOH!!! Thanks Yellow.

 

[bvstone]

What I did was before even removing the valve covers I put an "X" on the exhuaust cover with permanent marker. (didn't see any other markings). Just to make sure.

Guys, I got my vavles adjusted by the dealer this weekend. I was hopeing that this would resolve my non-wheelie ability and the slow top end problem I am having.

The dealer said that the valves were tight on the intake and loose on the outtake. He adjusted them and I am here to tell you that it really made no difference that I can tell. There might be a slight bit more power, but not enough to get the front tires off the ground by just hammering the throttle...I am going to do a jet kit after I get some more miles on it. I only have 200+ miles right now and I want to make sure that everything is settled into place and broke in completely before I put a jet kit on.

Does anyone have any suggestions on how many miles would be good to wait before doing something like this?

 

[parkgt]

I put mine on at about 275 miles. Can't detect any problems from it; now have 420 mile on the odometer.

Thanks Greg, maybe I wont have to wait to long then (assuming the wife will let me use the money LOL)

 

[RobG]

Just for the record, the exhaust valves are INTAKE and EXHAUST.

You may be having the same problem that my Rincon has... mine won't wheelie no matter what and has sucky top speed. I'd be curious to know what yours will do for top speed when you're ready to try it.

[hondaman]

What?

 

[marine]

Try what Rob? I am thinking the only way to try and get where everyone else seems to be stock is by using a jet kit. I think I am going to break down and purchase a jet kit and pray that 03rincon will help me install it when he gets a chance (being as he has done this on his). If I still cant get the performance I want I will put a pipe on it. If it STILL wont do what I want I might give the rincon to my wife and go get a 450R!
