About 8 months ago, was the last time I rode my 103 and I had set it aside after it seemed to lose compression and over heat. It did not seize, but it was popping and sputtering and such and managed to limp home. The upper plastic part of my stock gurtner carb had a crack in it and it may have sucked air causing it to run lean. Anyhow, I have the engine out and plan to tear into it. However, i am unsure what to look for and what to buy. My motor may be an odball, its from a fixed rear suspension 103 which was sold in a lesser common version and for some reason (maybe price point) it is non variated. i don't believe it is a 102 engine, just a non variated 103 variant. So with that said, I am unsure if standard 103 parts will work. I am on the fence with finding a variated 103 engine and swapping it out or rebuilding what I have. To make the variated swap, I know I need to do a few frame mods.
If anyone has a stock engine lying around from an upgrade build, I would be interested. Also there is a 103 lower end on her for sale, but it has a 5 coil stator and mine is 2 and I am unsure if the wiring is compatible. Anyone know?
Any help would be appreciated,
