[firecat99]

i was draging racing this weekend with my stock nytro and keeped with all the xp's and very happy got first in 600stock 2nd in 700stock and 3rd in 800 stock, but ill get to the point i did my last drag against my buddy and broke my rear tentioning bolts replaced it that day then broke them again, anyone else having this problem? because well for all you guys i have been running the new(well old i should say lol) ones from a 1993 exciter shaft and everything all works the same so it shows that yamaha hasnt changed in years but anyways can you let me know if anyone has been having problems with this thanks all.
