cam tensionors and guide noise

Hey Cbrfrenzie how do i PM you?
Took the exhaust cam out, taking measurements we'll see which is which now. I have a lot of F2 stuff if your interested. Have a set of alum rear sets u might be interested in.
Later

Weird, I can't PM you either... I've recieved PM's from other users here, maybe there is something in your control pannel you need to enable?

Yes I am interested in some parts... My email address is cdeardurff@dynojet.com, you can send me an email and I'll respond from there about the rear sets, cuz YES I am interested!

And sweet, with the cams out of the bike we are sure to figure this out! hahahah... oh and from your other post, I have made a degree wheel for my bike, its suppppper easy if you have a CAD program to draw in. I simply drew a circle 8" in diameter, then drew a line from the center to the edge (major mark). Then i drew a small line from the outside edge in about an inch (minor mark), with the angle between the two lines at 1 degree. I then arrayed these two lines for 180 occurances, over a 360 degree range, and BOOM your done

I can upload the .dxf file if that would be easier for you.

Print out the drawing and glue to a piece of aluminum. Finally cut out the circle with some sort of saw, and drill a hole in the center

Well, ordered the manual cct, and gaskets, should be able to get the bike back together this week. Called the stealership about a price on adjustable cam sprockets, so I could degree the cams, they responded that there was no such thing, didn't know what I was talking about. Hmm, you would think they would have heard about this before? How tight is this manual tensioner suppose to be? Is there a certain position the crank should be in when tightening it down? Can't wait to see what the bike will do on a dyno. Does anyone know what the effect is on changing front/rear sprokets when on a dyno? Will this give me bogus results if I run other than stock gearing?
Thanks,
Ron

You can order the adjustable CAM sprokets from that APE site I listed earlier. Its actually on the same page as the manual CAM chain tensioner is listed, right here second product down : CBR ZONE . When I installed my manual cam chain tensioner i first primed my factory one and installed it. made note of the cam chain, then installed the manual one and tightened it up a 1/4 turn more. If anyone else has a better way to set this please let me know! This has worked great for me for 20k+ miles of redline riding though!
Gearing is calculated out in the dyno, you should get very similar results for power and torque, however your dyno charts vs wheel speed will be shifted left or right. If you graph vs engine speed they should be very close. I've dyno'd with -2 +3, -1 +3, stock +3 sproket configurations all with very similar HP and TQ results.

Hey,
Do you run adjustable sprockets? I'm sure the dealer thought I was asking for a adjustable chain. Ha, all they would have to do is google adjustable sprokets and it would come up. Do you run diff. sprokets? Have to send me that wheel pdf u have. Looking forward to hearing it run. When checking over the carbs, I noticed two jetts that were clogged. One pilot and another one. Cleaned the needles, slides, and rubber gaskets. It's been awile since taking the carbs off, but ran the bike every year since storage.
Wow, the F2 carbs are smaller than the F3's.

Well, recieved the manual tensioner today, looks pretty good. Fired up the bike, and it sounds very smooth!, had one issue with a 6mm bolt that I'll have to tap for the engine cover. There was a slick ticking noise that I traced to the starter area. It would only click when the bike tilts to the left. I took it for a rip down the driveway. Letting it warm up, and the noise dissapeared. I'll see how it goes tomorrow, really excited to see what it'll do on the dyno.
