I've modified a 85 200x with an air cooled xr500 motor. all is coming together smoothly but I need more clearance between the exhaust headers and front tire. I was thinking a slightly smaller tire, and longer forks. then I read some posts on leading and trailing axles, a leading axle might buy me some distance, but what will it do to the handling at high speeds, turning, and hard landings. any and all advice welcome
