I am looking at fabricating my own "franken-bike". Have a low hour 2002 cr250 engine on my bench with all wiring included. I realize I will have to fab a mount for my electronic powervalve.
a little research on bikepics.com and oem
schematics after starting this thread.
85 & 86 chassis/body appears to be the same
87 body appears very similiar to 85 & 86 with the addition of rear disc brakes.
88 & 89 have different body, prob same frame as 87, but also has a one piece rear shock body/reservoir.
89 has inverted forks.
Now what I am thinking is 88 or 89 rolling chassis with 85 & 86 plastics. This will give me the look I want, disk brakes front and rear, & one piece shock body/reservoir. The forks dont matter much as I intend to find inverted forks and triples off a current model and adapt them to fit. To get the gold rims, I would likely use the 87 to 89 hubs and relace with gold rims.
