RS250/ RGV250 performance rebuilds

Discussion in 'Modifications and Projects' started by T_terror, Feb 25, 2006.

  1. Hey all.

    Im still a few thousand kays off my first rebuild with the RS250.

    Just curious as to what options there are into performance rebuilds.

    Higher compression ratio, race style exhaust, big-bore kit?

    Ive heard of a few things, keen to hear some more.

    Please do tell :)
  2. Depends what your into....Road or Track
    If you want reliabillity and a long lasting motor just rebuild it with stock parts.
    Not really a good idea to run a highly strung 2 stroke the road, it will need to be rebuilt very often!
    Check out that site if you haven't already, there's some good information.

    These guys come very highly recommended by me they will supply formula 3 spec barrels and heads which will give you a 600 super bike eater go the wail mate
  4. Unless your racing on the track, and willing to wear extremely short engine lifespan forget any of the overbore kits...

    Have a search for the Colin Skillcorn mod - which involves some headwork (an oring installation), with a aftermarket exhaust this seems to produce some very reliable and streetable power.


  5. Yeah i remember reading soemthing about a "Colin mod" on the UK forums, but didnt know wat the hell it was
