January 26, 201115 yr Hi! First of all, i am German and my english isn`t verry good.... sorry for that. I run into a "Bett-you-can`t-fix-it" thing with a 2000 TXT50 Boy that starts badly and runs sometimes reverse. I read in other Threads that this can be fixed with wider holes in the Ignition-statorplate. Anyway, there is another problem, some stupid Car-mechanic had dismounted the Cylinder ( for what reason ever... ) and now i don`t know if it is necessary to adjust the distance between the top of the Piston (at OT ) and the upper Cylinder sealing surface with different lower Cylinder Gaskets. (I have to do this at every KTM-2-stroke Engine in my Bikes ) Every kind of help would be great.. Greets, Klaus
January 27, 201115 yr Everything about these little bikes is a mystery. I suggest the way to figure out the answer to your question is this: get a hold of a parts diagram and see if different thickness base gaskets are available. Additionally, you can measure actual squish clearance of your engine. You can find rule-of-thumb clearance numbers on the web.
