Just a quick question does any one know how many links in the cam chain and the size.Just one more thing i just bought another 88 sc21 that has been down the road and is missing the side panels.I think mine wont fit because the dip stick in longerhas anyone seen this before.

 

150 pins in the camchain. Check earlier posts on camchains to confirm, and get part numbers.
There are secondhand panels on e-Bay UK at the moment for an 88, as well as lots of other goodies.

 

Here ya go weekendrider, diagram, number of links (shadow1 is right at 150), part number, and pricing from honda. Is the chain in the new acquisition bad or just doing a preventative replacement ?

Nice job, Idodirt.....problem with a Honda camchain is that it's a chain with no masterlink, which requires the motor to be taken out and the casing split. I just used a DID camchain with a masterlink, which we carefully peened over, and the whole job took a little over 4 hours, start to finish. I have pics if you need them, but Noe (thanks) did a very good writeup with pics when he replaced his camchain.......DID part no is SCA412 150 links.Motor is now really quiet, no rattles......at last !
Can't help with your query on the dipstick, but one of them seems to be wrong....!
The DID chain retails here for around 65-70 USD. If you need one, let me know.

 

Thanks for the heads up Shadow1, I didn't realize that the Honda one was endless. What a pain that would be. Clearly a chain with a riveted master link is the way to go here. When you replaced your chain, how did you break the old one ? Grind the rivet head off and press it out, or just press it out with a chain braking tool ? Did you consider other manufacturers for the chain (nothing bad on your choice, DID makes excellent products) ? Just curious how you made your decision.

 

I put a soft covering over the motor to keep the shavings out, and ground off two of the link pin heads with an angle grinder...A Dremel would be great too, but I don't have one...
I contacted local bike shops to check availability of camchains, and the one which was available "same day" was the DID. Takasago and Honda chains would have to have been imported, and cost double the price of a DID .....so, easy choice !
Peening the heads of the pins over on replacement was easy. Dad and Noe(thanks) have put up some excellent articles on camchain replacement.Check them out, they describe the process better than I could....

 

The bike runs good but when you Rev it to 10000 and let it drop to idle it rattles for 10 seconds then goes quited. I removed the top cover and the chain is riding high on the gears.(Chain must be stretched )Iam just going to use this bike for track days and i don't want it to lock up on me.

 

G'Day - Rev to 10000 and drop to idle ?- I hope you don't mean just revving it in neutral with no load ? Disastrous for most engines, if you want them to last - I'd change that camchain PRONTO if I were you - not too difficult, plenty of pics and good advice on the Forum. The motor won't just "lock up" either - you'll destroy the engine.......
