Ok i finally went and did it. Took a pair of x8 uppers and used some x15/x18 lowers. I ended up with longer forks for my x15 project racebike. Infact the stock fork's length is 22 1/2in from bottom to top. Now the forks i modded are 24 1/2in yep 2in longer. So now i can afford to raise or lower the bike if and when needed.
Right now my x15 project racebike looks more like a chopper! Lol

Thanks fellas....
@Cam no special mods, just unbolt and switch the lowers. I left the x8 fork springs in because they are longer plus they're progressive rate springs. IMO is better than the other springs because they also will cut down on coil binding in the forks.
Oh almost forgot, i get 2in of travel body weight compression test.lol I suspect that under heavy loads it will be a bit more.
I also think the x12's forks might be about the same as the x8's. Longer uppers with shorter lowers but don't quote me on this cuase i don't know the dia of the x12 uppers.

Looking good!!! Any new on the big bore kits?
I didn't tear into that engine yet, i was planning on leaving it as a 131cc till the bike was finished. Then swap in the my 180cc 4v motor.
Also when doing this swap,use the x15/x18 lower forkleg bolt. It is longer than the x8's and i think it will be more safer.lol

It looks more do-able now.lol but my main focus is to get it setup for the 10inchers first. Then bump up to the 12inchers.
