    I also successfully powdercoated the gauge holder. I can see myself doing alot of powdercoating! Its the same as paint regarding the prep, but it sure is a heck of alot tougher!

    Take a length of steel rod of of the right diameter, bend it to match the contour, weld it on, then grind and blend the welds smooth.

    Good ole 2 stroke Harleys:D

    Back in the early and mid 80's I had an SX175 (black with red/whire/blue stripes) that I chopped all the lights and stuff off to make a dirt bike -it was a great runner (I wish i knew where it was these days). I also had one of the orange 250's that was a street bike when I was in high school (but I always thought the 175 was a better runner - the 250 just was not as smooth)
    I would love to find one of these old bikes and relive the glory days of yesteryear.

    Finding an SX- or SS-175 or 250 isn't too hard...yet. Check Craigslist and Ebay often. You should be able to get a good RUNNING example for around $800 to $1200. You can find deals on them as low as $100, but those are usually parts bikes. The SS- versions are rarer and I would leave those mostly stock. They made thousands more SX's, you'll find a lot of those as dead parts bikes.

    f you prefer the smoothness, get the 175. It IS smoother because of the smaller piston. There is no rubber mounting of any engines, so a stock 250 is rougher. They are not Freeway bikes or tourers, they are mostly for fun. You COULD tour on one, but it gets tiring over 100 miles or so, especially with the buzzing in the handlebars. I had my stock 250 crank rebalanced to smooth it out a little more. The ST-250 gets strangely smoother the higher you rev it, due to its wide-open expansion chamber exhaust.

    Mods, can we move this to the old school two-smokers section? Thanks

    Sweeeeeet looking scoot. I like the fender, but it looks pretty bad-ass without it too.

    Are you running premix or using the stock oiling system?

    I am running 50-1 Premix. I could put a stock streetbike oil pump on it, but this is really just a playbike anyway, it only has a 60 mile range ( about 30MPG with 2 gal tank) It also lightens the bike up without the extra fluids/pump/lines
