Not if you’re retired and skint!! Oh that’s me!
As long as you’re satisfied with the value for money, that’s all that counts mate.
Mine goes on the Dyno this Friday as I’ve fitted a Dave Platt exhaust and a K+N filter on the induction trunking. Just to smooth out the throttle, loose the Cat, Lamba sensor and the restriction on the gears. That going to cost around £450 (@$700US), so cheap compared to the work you’ve had done.
So what tyres are you guys running with these big power engines?
