I don't have an extra clutch and pushrod assembly but I do have some opinions about LT250's. The designs vary wildly throughout their short model run and some of them are truly strange. The 85 and 86 uses a single sided reed petal which ultimately limited the top end power and bottom end longevity.
The 87 model used a dual side reed petal BUT the engine was a mid year change situation and didn't match the 85-86 OR the 88 and up. It was a bastard model.
The 88 and up used a dual pedal reed and more modern porting for more power.
The rear suspension is a cantilever style which is a little strange and limits the ability to change it out for anything else. The good news is, it's a fully adjustable shock absorber so unless you mess something up you shouldn't need to change it out.
