So I have this THracing cam chain tensioner gizmo.. I plan on putting it in between now and summit..talking to Scott on the 12 HOUR ride home we came to the conclusion that while I have it apart I might want to do the rings and that I will need a new cam chain since the one I have stock does not break anywhere. Joe C., Tex and anyone else that has opened these things up... what do suggest and where do I get it ? I was going to call westernhills and order some OEM stuff but wanted to know if you had a better idea...

Thanks from FoamHenge.

It's a standard RH thread.....cause when you try to use it to spin the engine it always comes flying out and hits you in the nuts.

I hope you have found a better way of spinning your engine!
Hard on the berries! Inless your into that kind of thing?
Ive heard Harley owners pay someone else to get hit in the nuts(kinda like a whipping boy).
You cafe guys are tough!

Sweet can only be completely appreciated if you have experienced sour.

Why do you want to split the cam chain? I'm not sure of the particular cam chain tensioner you have but I don't think you have to split the chain to put on any of them that I have seen up to now. How old's the engine, ie how long has it been run since it was last apart? I would also check the compression before I changed the rings. If its still good then I wouldn't bother with it. If its not then I would change more than just the rings. It would probably be worth boring to an over size piston also. Just some thoughts.

tsubaki cb750 chain is what you want. any place can get it. riverside, or weymouth honda. definitely replace the chain if youre going in. if you need rings, let me know. i have an extra set of 1mm over honda rings for stock pistons ill trade you for beer money at summit or something. you might need to open up that cam chain tunnel a bit to get the slipper to fit. youll have to split the cases to get the chain off cuz youll have to pull the crank to do it. so youll be tearing down the entire motor pretty much. its a pretty big job and since you dont know what youre doing, id suggest pulling apart a junker first, ask questions, then do the real thing. id wait til next year since the bike seeems to run good. id sort that carb gas problem. you definitely have a fucked up float or float valve. i dont know why itd be fucked up from lying on its side for 10 hours....but theres definitely something wrong there. that will probably be enough to keep you busy til summit.

You know you can split any timing chain with a chain breaker...use a rivet link and some lock wire to attach the new chain to the old one...pull it through the system...connect the ends of the new chain with the rivet link. Gotta have the new chain exactly the right number of links of course...including the rivet link.

It's worth it to find a chain that takes a rivet link, that matches the OEM size (number), doesn't matter if it's longer you can remove the extra links. I keep a couple of spare chains and a ten pack of rivet links.

the endless tsubaki is about 30 bucks. and its the right length and you wont have to worry about getting it together right. just install it. someone here did list the size pitch etc of that chain though. like mike said, nows not the time to be pulling apart your motor. install the pvl, fix yer gas issue, and go. installing the pvl will be enough of a challange, especially if youre using the block off plate at the crank end. (unless you have it already) that thing is a real pain to machine if your having one made. not that you need it. id say your doing fine, its running good, wait and learn a little more before you totally dig in. you dont want to be runing around at the last minute before summit becasue you just decided to "fix" something.

jnotthat,

my advice: install the pvl! then figure out where your fuel delivery issue is coming from. i don't know how it would be a float if it ran like it did in the races. i think you are having some sort of problem with the petcock, or some sort of vapor lock.

don't f with the cam chain unless you are sure you can get it back together in time.

The right float was stuck open. It pissed gas all night and into the van. It wouldn't make a diff when he was running the piss outta it. Gotta agree with JC, if you tear into the engine, there's a good chance you might miss summit. Try to get the PVl on, ditch the petcock and get those quick disconnects, (or a real tank) and call it good. And get rid of the alternator.

JD,

Actually what you should do is what Joe and others are suggesting for Summit and then tear into the engine. I would probably do an oversize bore, new cam chain and tensioner. Also a new clutch. like maybe some heavy springs and fancy friction plates. Then maybe look at redoing the brakes with new vintage brake compound. I wouldn't forget about some good springs for the front (progressives or something like that) and think about some emulation valves too. Next I think you really need to rework the frame bracing. The way you ride you've probably flexed it enough to introduce some fatigue so why worry about it, redo it and add bracing. Maybe you might consider some cosmetic enhancements too. I think a good paint job and surely a new seat will make you feel much better about you riding. I think if you start right after Summit you might get it all done by September and the rest of us can have a fun summer without seeing your ass disappearing around turn 8.

have fun

Mike O.
