I RECENTLY HAD MY 250R PORTED. I AM VERY PICKY ABOUT WHO WORKS ON MY STUFF. I WAS ASSURED THIS GUY WAS GOOD AT IT. WELL WENT AND PICKED IT UP AND LATER I WAS PUTTING MY MOTOR TOGETHER AND LOOKED UP IN THE INTAKE AND THERE WAS A MISS GRIND. IT WAS A CRACK THAT ONE END WENT TO THE SLEEVE. I WAS NOT TO HAPPY. THEN LATER I WAS PUTTING POWER VALVE BACK IN AND LOOKED MY CYLINDER HAS BEEN DROPED. RIGHT WHERE THE POWER VALVE COVER GOES IN. IT HAS MASHED THE SCREW HOLE FOR THE COVER WHERE IT WONT THREAD UP ALSO THE COVER WONT FIT IN THERE. I WAS SICK BECAUSE I FOUND THIS MINT CONDITION QUAD AND THERE WAS LITTLE TIME ON MOTOR. I CALLLED THE SUZUKI DEALER THAT DONE IT. THE OWNER IS A SUPPER COOL GUY. HE TOLD ME TO BRING IT BACK AND WE WILL GO FROM THERE. IN THE FUTURE WHERE DOES EVERYONE ELSE GET PORTING DONE?
