Hiya,

I'm racing in the annual race at Mondello Park next month. The bike (2000 Honda C90 non electric start) is bog standard and even though it will be dragging my 16 stone bum around I would like to keep it standardish for the Standard Class. But for me the rear brake pedal has ground clearance issues. Can anyone recommend a set of pegs/brake pedal/gearchange setup that I can pick up at a breakers cheapish and remove the original setup.

Also any known cheapish modifications to make it run as quick as possible receommened?. I might drop a tooth on the standard rear gearing but reckon anything more than that it would struggle to pull to top revs with me onboard.

Thanks

Buy a mountain bike brake lever, and rig it up the the rear brake, then remove the brake pedal altogether. I just welded on a few nut to the rear brake arm for the other end of the cable. Worked a treat, and cost me about £3 to do.

Retractable pegs are a must to avoid digging in.
My bike has these......

Plenty left-hand brake levers on Ebay. You can get away with using the original rear brake rod, turning drum arm the other way up, and connected to a handlebar mounted lever and cable.
You might want to go down one tooth on the front for Mondello as straights aren't that long.

Look forward to see you there!! :) There's eight Plop teams competing this year, two of which are defending class champions! :D

Hi Guys,

What size Bridgestone BT39SS were you running? was it the same front and rear?

Thanks!

Matt
