I have a problem with my turbo (garrett T25/28) on my gixxer 750, and wondering if you guys could help me out with it.
The bike was running very well, with no problem at all. After a couple of 2nd and 3rd gear runs to about 8psi i rode for around 15 mins. Did a u-turn and a quarter throttle accelleration up to the speed limit when POOF - no boost, or only half to one psi. I rode home around 100 km and pulled the tupperware off and could not find any boost leaks etc.
Pulled the dump pipe off and found one blade on the drive side of the turbo had a large chip. (see pic of 1 blade broke)
i would have thought this would not be the problem, so i put all back together and took for a 15 minute ride to see if i could feel or hear any problems. only 1 to 2 psi of boost and then nothing - would not boost at all.
Pulled apart again, and all the blades on the drive side have been torn off. There are no blades left to drive the turbo. (see pic all blades broke)
My question is - could something have come from the motor to cause this to the first chip?
Could the first chip have caused the rest of them to dissintergrate?
The turbo was used, but recently serviced. Any help appreciated, wso it doesnt happen to the next turbo i get also.
