For everyone who wanted to know, here is a list of all the parts in the GYTR 84 kit. I cross referenced some of the numbers and found out that the cylinder IS a stock 90 cylinder, every thing else seems to be original. The rotor housing and rotor assy (I think thats the oil pump) numbers dont apear to be right but maybe they are just not in the system yet.
Just to let everyone know. I just checked on the yamaha dealer site and the oil pump # xlu-13303-00-00 has been discontinued. they still have a few in the california warehouse.
I ordered everything for the top end and when I checked the piston it came with the rings and pin, circlips. So if any of you want to replace the top end, order the piston and the gaskets and you are good to go!
Hey!!! have anyone replace there piston and ring, from the 88cc Kitaco kit yet, and, if so where do you get it!!! I just got the kit on my sons bike, and it haul a#$
