thanks for the info, good to know.. i have one of tecriders spacers incase i ever need to do this on my 85'

Nobody knows if this is possible??

sdnative, yes my previous comments are meant for the exhaust brigde.. .

just make sure you relieve the exhaust ports before you assemble the top end.. Even though you're using a cast piston you could still drill the oiling holes on the exhaust side..
Once you get it up and running, don't go overboard with jetting.. keep it on the rich side.

I don' know why some still think cast pistons are better than forged.. bottom line is cast pistons are not as durable .. good luck with your build though, im sure the bike is going to be nice. Cause... ahh.... I've used my brain to decide they are. Old school cast pistons sucked, I would agree ther...

Dumb question time . . . . Brand new stock jug 89.0 bore, brand new stock cast piston, brand new standard rings . . . . wash the Honda honey off the bore, slip the rings in with the slug so they sit square, end gaps measure 19 and 20 thou. . . . . is this about right ? I know there was a formula th...

Hey guys, sorry i don't have a buildup thread, i just have videos of it.. it's all in stock form except for the DG pipe.. it has new everything including a brand new cylinder/ piston/ bearings/ clutch , chain , swing arm bearings etc etc the bike gets run every weekend , mostly on tracks.. i've trai...

supergreg is right, my 85 had a crushed ball also..

the only thing to do is inspect it.. seriously it's easy.. you have to make sure the pushrod is engaging on the arm properly.. take off the clutch cover and outter clutch hub.. you need to see the pushrod move while you are working the clutch lever.. i'm sure once you pull it apart the problem will ...

I didn't want to try this because I'm cheap LOL I was going riding on that weekend and wanted to fit one on for the time being.. I"m not cheap by any means..

well I would pull the clutch cover off, relieve the tension on the clutch basket then start at the clutch lever and work your way to the clutch lifter that sits in the clutch basket assembly.. this should be an easy problem to diagnose..make sure the clutch lifter arm behind the stator cover is not ...

EXACTLY

wisecos always get blamed but 99.9% of the time it's the guy assembling or machining the cylinder.. how much piston to wall clearance did it have and what was the ring gap??? Wiseco pistons have been used for YEARS by millions of people and pros with success.. we used them in drag racing for years t...

well its not that hard to pull the cover and have a look.. remove the flywheel cover also and look at the clutch arm. did you have it apart recently?

thank you sir

Thanks Jay, the cometic gasket comes in every Cometic and Wiseco head set for 1989-01 motors. C7020 and W5223 are their part numbers. The material is aluminum with a sticky coating on both sides. The reed gasket and the base gasket are made of the same material and are .012" thick. thanks for ...

the base gasket was a moose racing gasket. I read in another thread roostius recommended the cometic metal gasket.. i was going to order one today if I knew the exact one to get.

IS there a part number for the cometic base gasket with metal?? Is it an actualy metal shim or is the gasket still paper with metal in it?

had part of the base gasket blow out yesterday on my 85' CR500.. all the cylinder nuts were tight but it still blew a small section out of the left side.. the lower cases and cylinder is already dimpled to hold the gasket in place.. this happen to alot of these bikes? im thinking of maybe using an a...

thanks for taking the time to reply.. I knew it had to be close, i was just being over cautious before I mount this one.. it's a spare saver off another bike I have... it will work no problem, i just had to decide how close to mount it.. So basically i'll mount it so the chain doesn't have a chance ...

anybody??? is 1/4" too far??

hi guys, thanks for your reply.. Well what I'm doing is making one from another bike fit.. I just need to know how close to make the clearance between the saver and the chain..

I know this might be asking a lot but I was wondering if I can get the measurements between the inside edge of the case saver and the chain.. I'm in the process of making a Case Saver for my 1985 Cr500,, I want to make sure I get the proper amount of clearance between the guard and chain.. Too much ...
