    XL250s 1979 more power

    This is the problem with my 540 Curtis. Tracks over here are fairly tight and slippery. I am going to drop the motor in to a 76 Husky frame, if I go ahead with it. we have a pre78 class over here and the 250 motor is class legal

    I have taken the balancers out of the 500, also have the smaller flywheel. I remember your posts on this before Looks like I will try the 338cc set up probably

    What is the weak part of the gearboxes? I know you can weld steel rings on to the earlier motorsport XL's Are gearbox parts interchangeable with the 500s?

    XL250s 1979 more power

    Before I start I may as well mention I have an XR500 I use in MX. I also have an XL250 motor kicking around. I occasionally find the XR a bit of a handful, so was wondering what can be done to the lowly XL motor, for MX racing. I have seen they can be taken out to 305cc, but can find no info on how to do this? Can a jug and piston from a later XR350 be fitted, as I think 350-400cc would be ideal? Any advice and thoughts greatly appreciated

    CRF230 pipe on an early XR200

    CRF 230 performance pipe. What do you guys rekon. With a bit of fiddling, will it fit?
  8. Do you guys rekon that this would fit on to the humble XL185? It's saying it 250cc but i'm not so sure? http://www.ebay.co.uk/itm/Piston-65-5mm-Rings-250cc-Big-Bore-Cylinder-Kit-for-Honda-ATC-200-XL200-223CM3/262525645447?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649

    76-78 rm250

    The forks should still be 38mm I think, no no problem there. I have a RM400 alloy swing arm on my 77 RM370 and it fits just fine Hope this helps
  14. Motocross I was thinking. Not the cycle parts, just the engine really
  15. As in the title really. Are they not capable of being made competative?
