    AWESOME! :clap

    As a T250/T500 owner, I have often enjoyed your earlier racing photos and I'm overjoyed to see that you are still podiuming!

    Is 540cc as big as you can go? I was at an ice race or a short track around '80 and there was a TT500 with tons of hp and a stock frame swapping all over the track. Some guy standing next to me said it was built up around 700cc. Was he full of it I guess?

    I know Powroll used to make 605cc kits for them. A friend had one in a street plated '77 TT500 in the early '80s. I never rode it but heard it was pretty bad a$$.
    Never heard of a 700cc kit. I think that would be pushing the available space inside the engine.

    I have a 540 street-tracker...and it's plenty. Even with super-tall gearing, I can wheelie it through 3rd gear. I've seen some 570 motors, but they tend to be like time-bombs. You can do the 540 kits without going too crazy.

    Well... The TT race today was not as successful as the shorttrack yesterday.
    The infield of the TT track had banked corners, much like you see at the Supercross races. Clay at the bottom and much looser dirt up high and this led up to the jump. My buddy Dennis and I were in heat 6. I started raining pretty good when we rolled up to the starting line. I give my shield one last wipe and the starter waves the flag as the rain intensifies. Clay and moisture SUCK!!! We ran 6 laps. I crashed about 50 times without hitting the ground!! getting really sideways before the jump was not good!
    The races were called right after we got off the track.
    My 65 year old body just can't take this kind of abuse.
    Margarita time...:freaky

    Again. good job! Wet clay sucks on a dirt bike with knobbies, let alone dirt track tires. You have guts for finishing that race in mud conditions and vision blurring rain on your shield. :thumb

    Thank you for the kind words!!
    I feel like I was the punching bag at a boxing camp!!
    Sore all over. Glad there's 3 weeks before the next race.

    This explains why I felt so bad, physically after the two day race weekend. It wasn't so bad after the shorrtrack on Saturday, but landing off the TT jump on Sunday with a little over, well.... You can see for yourself.
    I never touch the forks during the build and paid the price!
    Not ashamed to admit... I really hurt, for about a week and a half. Just getting to where I feel I can work on it to get ready for the race on May 15th.

    Today, I put the forks back together with fresh oil.
    I was able to compress them about 2 1/2"!!!
    About double the travel they had at the last race.
    Not really sure what the heck was wrong with them...
    The gearing was just a bit too low in 3rd gear (end of the straight).
    Engines revs were a little higher than I would like, so
    I went to a 52t rear sprocket instead of the 54 I started out with.
    Next race Wednesday May 15

    Did you roll or otherwise check your tubes for straight? Could also be bent triple clamps.
    I usually clamp the tubes only in the triples and check the tubes for parallel and on the same plane with a 12'' caliper and a piece of plate glass.
    Sometimes even rotating the tubes in the clamps can free things up.
    We're getting to old for hard landings!

    Yeah!! It was like riding a rigid!! Not fun... and who the hell are you callin old? :evil
    Didn't get real crazy with measuring. Cleaned them up and assembled with fresh fluid... The move and will soak up some of the bumps. That's all I need. If I was fast, I'd be more thorough. :lol3

    Got some photos from the April 20-21 2013 race weekend.

    Start of the Vintage Amateur Shorttrack Main on Saturday. I think my TT hooks up pretty good, it's lifting the front wheel.

    Going into the first corner, the 540cc bikes are showing their stuff. The 16 bike is a Panther framed FAST MOFO. The guy can't ride it though... He crashed.

    Cruisin to a third place finish on Saturday April 20, 2013

    Sunday April 21, 2013 I thought I'd race the "Over 50" class. The TT's that I raced against yesterday were heavily modified and I had my hands full with my stock motor. I made a big mistake!! All the "Over 50" guys were riding CRF450 Hondas or YZF450 Yamahas! It rained in our heat race and they called the races for the day. Thank God!! My front forks were beating me to death!

    [​IMG]

    It rained so hard during our heat!!! You can see it in the photo. The infield was clay and got real slippery with the rain!!
