    you can’t tell if fork tubes are bent prior to rebuilding them LOL. You can’t see 2mm from bird shit. Leave this poor man alone. for your pods- silicone the outside at cap, fill each little seam up. I silicone the inlet and outlet at the seams to the cap/outlet rubber, if you wish to...

    The xs400 is a points ignition engine. Tons to google on that. There is nothing to learn on this forum except for how to properly enhance your ability to troll. Www.google.com for info Www.ebay.com I’ve just made this forum irrelevant.

    This forum sucks like most do because a few butt hurt dudes don’t know much and they try to scare people away from learning. I don’t have to tell you guys anything you can learn on your own time and dime. The more I learn about engines and atmospheric pressure, the more I realize the guys on...

    Tell me where the basic sounding questions are other than the valve lash? When you say old machine, it works the same as any engine. They all work the same. 30% past STOCK redline taking in stock assumed air and stock assumed fuel. Mine is a little hot rodded out... also, it was cold (46...

    It’s hard to think that you would know. Its also hard to think that you’ve got the experience racing and or getting a motor race ready. If the people on this forum did, they wouldn’t ask me simple questions and have trolling remarks. My motor ran flawlessly, NEXT!!

    I check everything, every nut, jet, and bolt. From timing to a 4 minute valve check. It’s a simple motor and when it blows up, I’ll rebuild it or use my spare.

    My tach isn’t off, there is a reason to “over rev” on a cushion half mile. I didn’t use the brake. There is a very good reason...

    Had my first race. Took 4th place. Revved her up to 11.5k/12k in 3rd gear in the straights. Corners down to 6 lowest and back up to 8k and then back to 11.5/12k. Motor wouldn’t blow? Motor was great, faster I went—better she handled. Was a 1/2 mile cushion track in Wisconsin. Raced in the...

    I have to run period correct forks, a brace would be ideal but I don’t have one! I like having the weight up front, helps her stay in it lock to lock but right now I have too much preload in the rear and I’ll get that sorted out. My camera died after I put it on the tripod, may go back out...

    Tire Question

    We only turn left. For TT races we have 1 right hand turn and one jump. Because we slide into turns and drift the bike, we eat up the tire one side only. So we have quick change hubs that allow us to put the rotor and sprocket in either side, no issue. I haven’t met many nice mechanics, we...

    Tire Question

    Do you read? We CAN put it on both sides. Means the disc can be on either side too. One side of the tire wears, we flip to the other side (tires are expensive and only can be bought at track) It’s called quick change hub

    Tire Question

    Something as small as going from a 110 to a 120 is a massive change in handling and essentially how easy it is to push the bike down and drag a peg. If I wasn’t racing my xs400s, I’d get the factory sizes. Now I have 4” rear and 3.5” front and it’s not fun unless I’m in the dirt and sideways
