    Ugh still coolant issues!

    You need to lap the head and jug. The orings only seal when the bike is cold. The metal to metal seals after the bike is warm. If there not perfectly flat then u loose your seal once warm.

    seat foam

    I have a 99 yz250 and the seat is killing my ass. Iv had several other bikes and never had this problem. I stand and sit while riding about 50 50. I havent seen any after market seats for this bike except sdg and all the reviews say there just as bad. Anyone got any suggestions.

    Its a Cornwell tools checker so its a good one. Not saying it can't be bad. I have been looking to borrow one from someone else but can't seem to find anyone with one. I did also clean the carb trying to fix the prob with the surge

    also getting some surging at 0 to 1/8 throttle since the rebuild but only after the bike is very warm. Doesnt matter if in gear or not

    So I have rebuilt the top end with a wisco piston kit and still only getting 150 psi. I took some carb cleaner and sprayed everywhere looking for an air leak and can not find anything. any ideals btw old piston looked brand new and jug was absolutely perfect

    Well i just read ur supposed to warm the bike up which i did not. Im putting the tester in the spark plug hole and kicking the crap out it about 10-15 times with wot until the gauge doesnt move anymore

    ok I went and checked it again and it only has 150. I plan on doing a top end but it just blows my mind that this thing runs as well as it does. Has great throttle response and has great power when I wont it. Doesnt make any engine noise i can hear.
