i bought a little lem mx'er upside down forks looked to be in good shape lots of compression, she trys to run kicking but will only idle for a few sec. no problem with that. but when i looked closer and i noticed it was piston port [no reeds] the engine# is 10707 the model is a 00890. i don't know if it is worth putting in a bike frame? dyno streach cruzer. any info would go a long way as i cant find anything about this motor. thanks dennis
