Hi mt bandit,

I've not touched the engines but sounds like you're on the case. The CanAm engines are remarkably lighter than the MT engines to lift in an out!

Also check that you have a Mk2 clutch cover. The Mk2 has a few ball bearings on them which makes the clutch easier to operate (once the extra plates are taken out of course). The Mk1 can be fitted with ball bearings as well I believe to make it like a Mk2, Yeti (Peter) has done that with some of his clutch covers I think. But worthwhile doing while its on the workbench.


Good luck and all the best.

Jack
Good tip thanks , I've sent Laurence some pics he will put them up this evening

Thanks mate ,,
So the top pic is part of the original engine ,
The bottom pic is part of the doner engine, so this was the chosen cases to start the rebuild,,, the crankshaft that fits these cases has the holes in it ,,, hopefully itll go better coz its lighter ,
So crank cleaned and ladeled with semi synthetic 2 stroke oil ,
Bagged and in the freezer ,,
I'm going to oil all the gearbox and bearings in gear oil ,refit,
Then hopefully drop the frozen crank in and put the other half on ,
But there is a small o ring stopping me from reconnecting the cases at the mo , so crank might be in the freezer for a few days

I've got the clutch arm upgrade bits in the shop as the can am early style clutch arm was used on the pre 84 four stroke engines. I've fitted the kit to both types of engines and as mentioned it make for a lot better clutch action and it's easier to adjust!

I'll be assembling another can am motor soon! Looking forward to doing something a bit different!

Ah yes thanks Laurence,
Although these are opposite cases they are from 2 separate engines , So the rebuild has come to a bit of a temporary stop,
However I may have been rescued , my mate is going to have a go at welding them , hes seriously good and if anyone can ,he can .
Magnesium being very tricky to weld as well ,
So they've been through the dishwasher, and I'm getting ready to post them ,,
As far as I can tell this disc valve damage is their Achilles heel,, anything wrong in the high revving 2 stroke top end ,,and it gets in that valve , damages the casing , and basically throw it in the bin ,
