My friends dad was selling a old 200 xr for 180 $ so i took it, he said the piston was changed by his "mechanic" and it ran two years ago, and probibly just needed new gas,
Im not sure what year it is, early 80's i think, the Vin ends in 85, but i dont think its that new,
anyways, I drained the tank and bowl, cleaned the main jet, filled it with new gas, and kicked it over, not sure if choke is up or down, theres an arrow up, id have to look.
i got a few back fires, theres good spark, one time it backfired so hard allmost wrecked my foot, and then the kick start stayed down, i pulled it back up, and wouldnt turn over the motor, so i put it in gear and while on the kick i can get it to turn back over, and same everyonce and a while, im guessing it chiped the gear or something, should I open up the trans and look?
im getting gas in the cylinder, plug is wet, the timing must be off since it mostly backfires out the carb, or the valves arent setup right, but theres loads of compression, i havent put a compression gauge on it yet, I might tomorrow.
how do i check tdc at the crank and top end ?
also there's a slight oil leak at the lower bolt in the mag side case, thats supposed to be dry right ? the crank seal is blown then, i havent opened the case yet, i will to find tdc correct ?
also the air box, theres missing more of the filter right ? not just the cover ?
heres some photos
thanks for any info
