Splitting the case

I just put my case back together after spitting it and I am wondering if the bolt's need to be torqued on the bottom of the case & if so what is the torque spec /sequence for an 89 Exciter 570

wow... sorry I cant help right now... I just ordered the manual and
it may be a few days before I get it...

do you have a thread on your rebuild? what did you need to do
crank bearings... rods/rod bearings???

Im sure you will get the specs before my manual arrives but if not
I will certainly pass them along.

I may be right behind you in this monkey business...

sunday was a really bad day....

ouch.... i was reading this potential issue...

would you say it was a tough job.... ??
how much time was it for you to do...
doesnt seem to be that bad but im new to snowmobiles
Ive had and done mx bikes... but mine were all air cooled...
so pushing around wires and hoses under a cowl is a little bit of a pain..

why did you bore?

If not... then Im still in the game...

Until you pull the jug's, you wont know you might just have stuck Ring's so a hone job and a new set of ring's might do it. As far as which pistons to get, that falls back to you get what you pay for, or at least I always believe in that

i guess im looking at Wiseco .... they were always a good manufacturer back in the day...
but I dont wanna date myself...
and they seem to offer a complete top end 2 cyl kit w/ gaskets etc etc....
Im not looking to save $50 on two pistons just to get the skirts falling down...

open it up first, make sure of what you need before ordering anything.
