The first time it blow up it was making 65bhp not very stressed crusing at about 80mph....
2nd blow up, on the way home from Andys 90mph... ohh its sezied again
3rd blow up going to work, in a 40 zone, oh thats a suprise its seized again!
4th blow up, The very next day, now running 230 main jets (to be safe) .. you guessed it... 70mph it sezies
5th blow up, Me and Andy after a nice day out of plug chopping and good fun, came out of a roundabout, and by george its seized again
6th time, Im starting to get pissed off now, now making 71 bhp but still running 210 mains it detonates and sezies... manged almost 500 miles this time though!
7th blow up, ok 75 power jet annnnd 210 mains.... er yeah, that one seized too.
Now I've raced CR500's since the year dot, my 250 has never, not once, seized and I can do the hour trip from my house to Andy's near flat out, and I mean flat out 13,000+ all the way, and it wont die. Yes I wanna hammer 'em, I want to rev the living crap outta them, but that is how you ride one! The 300 so far, on the 8th attempt, is hanging togther... but the 250's faster!
