If replacing cams do you need to pull cam chain tensioner? I have my supposed GSXR 1100 cams to put in my 750 kat, and I am wondering if I need to remove the cam chain tensioner when pulling the cams off. I think, I have too pull the tensioner out, but If anyone has done anything like this I would like to know.

Check the chain for service limits. Take the tensioner out. Clean it. Replace the spring if it's over 6 years old, if you suspect it's weak, or if you've found substancial play into the chain. Then start working on the chain and cams. Reinstall the tensioner at the end. If you replace the chain, replace the tensioner spring while you're at it (to be on the safe side). And by all means, get your hands on the factory manual if you're doing the cams! I've seen it in CD format on eBay for $25 or under, although I prefer my paper version.

I have a Haynes, which I bought about 1 week ago. I have the cams out now and have to find some non-destructive way to remove cam sprockets, off cams. This should be strait forward.
The other thing is that I am installing an Ivans jet kit, but the screws on the back side are stripped and I need to find a way to get them off the carbs. I have tried penetrating oil and vise grips. Next i will look at my Dad's tapping set.???Is Effingham a swear word?

They have lock tight on them, when I pull them out. And some of the screws were deformed, stripped, when they put them in. Im calmer now, but I was angry about some one being dumb enough to strip screws going into the carbs at OEM level. I will try the brake cleaner method, maybe the quick evaporation will shrink the screw enough. Otherwise, I am going to go the dremel path for the 5 messed up screws left. I tried putting them in hot water to get the assembly to expand and that helped on some. Now I have the carbs pulled apart drying over night. The spot is too tight to turn the vise grips more than 70 degrees. Its just a pita. Thanks for your help.Is Effingham a swear word?

Update,
I took my carbs to Lee auto parts. They have a machinest on site and for 25 dollars he got the 5 stripped screws out. The orginal question of taking the cam tensioner out, I took it out since I pulled cams out. hehe some time whens its warm up again ill pull off the head and put new cams in, and finally adjust them.Is Effingham a swear word?

Umm what do you mean by degreeing ? You could alway use an ingintion advancer. But if that is not what you want, get adjustable cam shaft sprockets. That way you leave the cam in and you "just" adjust the cam shaft sprocket and rotate the cam. There is a difference in the cam chain and cam sprockets from the early GSXR and the 98 + Kats. So, if you can only find an early adjustable sprocket. You might have to change out the cam shaft sprocket on the engine crank. If that can be done. If you can take the cam sprocket off the crank shaft, you will need to split the cases. To get a chain and sprocket set of an older GSXR on the kat. But your bike might be an early kat and cam sprockets and cam chain might be the same as an early GSXR. I know I have seen adjustable cam chain sprockets for early GSXRs.Is Effingham a swear word?

Yeah, I may do some tuning of the Kat engine with some different cams next year, since at school we've got some software that will determine optimal cam shapes for the given application and engine, and I've got access to an engine dyno to test them on. But for now, we're trying to take some new cams we ordered from http://www.webcamshafts.com/ and get them in an R6 engine. The cams have adjustable sprockets, and no markings, so we need to degree them in the overlap and timing we want. For all of us on that project this is our first time putting in cams, so I'm just looking for some pointers.
Once again, sorry to hijack!
