The later model Sherco swingarms are still essentially the same shape. Try a later model guide...it mounts the same way, I think there's a good chance it will fit.
Don't bother re-kitting evo rear brake mcyl. high rate of failure... If you enjoy spending hours and hours of your time bleeding, testing, and scratching your head when it's still not right, by all means re-kit it
some of the older Sherco engines do have a tendency to kick back...I never investigated it but I think it's a lot to do with the kick start gearing which is quite fast and the short length start lever plus the lever is set higher from the ground, so when it does kick back you really feel it..I could be dreaming though
clean the middle and header pipes then report back. Use a heat gun to get them self combusting, compressed air to help it along, middle section needs constant dousing with water (soaked rags) to control the aluminium temp. Don't heat the middle section carbon deposits to bright red as that's about the melting point of the fine steel wool inside. Cherry red is enough. Two people makes this job easier to control the temp..
And you might p*** the locals off with all the stenchy smoke in the process so keep what you're doing out of sight and do it at a mates place ?
No wiring diagrams as such for these. If you're reasonably savvy with bikes and wiring in general, I found this gg schematic is pretty close as far as the parts used and the colors etc.

the frames are different, the plastic molding is different and not interchangeable, the decals are different, the tyres are different, the suspension front and rear is different, the wiring is different, the power/torque curves are different, out of the box the set up is quite different, they steer handle and react quite different
