125-200cc 04 WRE/WR125. Slowly getting there.Jetting for a TM38?

I purchased a WRE125 last year for absolute peanuts. However itd had a hard life, itd been blown up and left to stand for two years. The top end was goosed and the bottom end seized solid. So after many months trawling ebay i finally found an engine (2004 WR125) I installed it. I have a dep pipe that im trying to repair, its in shit condition though (various hairline cracks and such) and ive just bought a mikuni TM38 from a WR360. Im presuming it will be jetted completely wrong, any advise on whatll give an ok setup? Close to stock or whatever, its been a while since ive been on a bike, let alone a 2t. Also, with regards to electrics, are there any schematics available for both bikes? Just i have a lot of redundant wiring and the engine harness doesnt look too compatible with the loom.
