congrats on the shorty pants mod! mine was more of a "
longy pants mod".
at this stage i've just put the rear tire from a DR650 on the front wheel (bridgestone trailwing) as that's what i had lying around and i have almost no money to throw into my conversion. like gordo, no wobbles at all at any speed, but then like his mod i do have dirt bike forks on which has lifted the front end and given it more in line stability.
