    scratch building 85 250r.

    I have an 85 250r Iv had since 85 it was couple months old with a tank or 2 of gas threw it. I rode it raced it in 85 and some years to follow off and on . I would like to race Unadilla this next year and I don't want to alter my current 250r because Iv had it so long its like a member of the family. I was given a decent frame and some other parts a couple years ago so that's were this thread comes in. Im going to build a liquid r for racing and keep my 85 for riding and occasional drag racing. I have a lot of parts stashed for the build Iv been buying what I need as I find. 3ww and trx250r have been awesome for buying good part at reasonable prices aswell as Craigslist. Only part from Ebay is the motor. Im going to turn this thread into a build thread when build starts. Click image for larger version.

    I'll be following this one for sure!

    I did a frame-up rebuild on one of my R's about 3 years ago now. It was the trike I had back when I was in high school that I sold a year or two after I graduated. It went around to about 4 other people before I got it back in a completely flogged state. I really enjoyed doing that build and the members here on 3WW were a huge help in getting the parts I needed often times for half the price one would pay on Ebay.

    Post up a WTB in the classifieds and I'm sure some of the same folks who hooked me up with good parts for great prices will pop in with offers.

    Enjoy the build!
    Trikes:
    '85 ATC 350R
    '85 ATC 250R
    '86 ATC 350X
    '85 ATC 350X
    '84 ATC 200ES Big Red
    '84 ATC 125M
    '85 ATC 110
    '85 ATC 70/110

    I raced my 83 200r there on the 2nd practice. Nice track great for begginers.I met Greg Huntly and his wife and 1 of their friends. We practiced with the quads.Im planning to rebuild my aircooled 82 250r quad so I can do some more racing. Id like to try TT on quad and there are some crosscountry racing at the ski resorts near Syracuse.Rich Daly has them aswell as hill climbs.

    In case you haven't thought about it . If you want to get the most power out of the engine, you need to get the compression up to over 185 and this means you would need race gas . Also, one area many people don't consider when building a high perf engine is ignition timing . This often needs to be changed to get the optimum perf and it is not adjustable on that model, however, you can buy an adjustable kit for it . This is definitely something I would do if you don't install a CR ignition etc.
