cr500 engine upgrade questions

Post by rynwilliams »

I have a 1986 CR500 that i am currently rebuilding.

I have managed to get a new 2001 clutch casing to upgrade that so changing the clutch will be easier.

The crank need sorting as there is a lot of play but i am having a hard time sourcing a conrod for the 1986 engine as it is shorter.
My question is if i were to buy the later cyclinder could i fit the later conrod and piston to my crank?

Also is it possible now i have the later clutch cover to upgrade my clutch to the wider type in the later engines?

Any other recommendation would be welcome.

I have just placed an order with service honda.

Can anyone confirm if the later wider clutch will fit as a replacement for the standard 1986 clutch. I have replaced the clutch side casing with a brand new one from a 2001 engine.

Thanks

Yes i have that pdf document which is a great help.

I am wanting to get a complete new clutch for the engine, if i buy the parts (basket and clutch kit etc) for the later clutch 1990-2001 will i have any problem fitting it in my 1986 engine. I do have the 2001 clutch case.

Thanks
