if its going to be a race bike wouldn't you just want a frame and wheels and use yz250/400 triples/forks and put a klx or pe swinger in with some decent shocks as stock suspension wont cut it,not then and surely not now.the klx swinger has the bottom shock mounts in the same place as the 500 one just slightly longer,even the chain guard nearly lines up with slight spacing with washers only needed and the same with the rear wheel.ive made wheel in adapters to suit the different swingarm bolt diameters that are for sale.pm me for moe information
Thanks for the (only) rreply Matt
That's sort of what I've got now but it has evo forks and square alloy PE rear swing arm and wheel setup in a HL tribute bike (I won't use the word replica as it uses the TT frame). Without destroying that bike as I like riding it, I wanted to use the motor to build a bike strictly pre 78 legal .... I have PE front forks but I don't think they aren't pre 78 legal and I would be happy to use a stock swingarm with upgraded shocks (to a maximum of 9 inches). I would of thought the KLX alloy swingarm would not be pre 78 legal?
Anyway, I can look for a YZ D front end and run that and then just run a set of marzocci's on the stock XT/TT frame I guess. Not too concerned about being a race winning bike because it doesn;t matter how good it is, I'll be slowing it down
Happy to hear more of your thoughts if you have the time.
Cheers
