Brings back fond memories, though I never ran geared one's, 100cc fixed for me. Nowhere near as mental on the straight bits (think top speed on the tracks I ran never got above around 75ish), but still fun having an engine doing @21000rpm, burn't like hell too if you let your arm drop onto the engine!
Still got mine in storage, may have to get to wigan or something for a play!
If someone finds a link, I've seen video's before of a 250cc Isle of Man kart street race, absolute bonkers!!
