trex banshee Posted January 20, 2009 Report Posted January 20, 2009 Hey guys I got a question, ive been meaning to ask it for a while now but I just completely forgot and now its winter and I havent been riding my bike, but anyways on my trex bike, the pipes will blow off of the exhaust flanges probably between 1/2 inch to 5/8 of an inch when reving it way up. Is this just a sign of weak exhaust springs or is this a sign that big bore pipes are needed? At the time I had one fmf spring and one oem yamaha spring on each pipe, its all i had at the moment. Ive got all four of the genuine yamaha springs now that ill try this next season. I know that bb pipes are meant for 535 or bigger or some stuff like that but i also know that many others run them on smaller cc's. Mine is 427cc. When I was looking to buy pipes last year I done research and talked to Matt and he said that I could be boarder line but he told me to go with the sb. Any info appriciated. Thanks :beer: Quote

Thanks :beer: yea mine did that just need new springs, I got some so tight I could hardly get em on but prob solved. I have rockets over rz exaust flanges, so I dont think its a perfect fit, but ithey stay on now. Quote
J-Madd Posted January 20, 2009 Report Posted January 20, 2009 My 14 mil does that with BB/BF pipes. The springs I have suck. I'm thinking about just using wire to pull them tight. Quote
trex banshee Posted January 20, 2009 Author Report Posted January 20, 2009 ok, ill just put all four of the strong springs i got on it and see what happens. Thanks again. Quote
locogato11283 Posted January 20, 2009 Report Posted January 20, 2009 i think you just need new spring homie. after time the stock ones will wear out, just like any other.. the ones i have are so fuckin stiff i can barely get them on.. even busted my fingers open a few times doing it. Quote

Dont be a pu$$y, ya fluffer. :laugh: Yeah the stock ones work best! Quote

mignumspeed Posted January 21, 2009 Report Posted January 21, 2009 Ill put all four yamaha ones on it next year...those damn things are expensive! you can make yourself a tool to put those springs on with take an old srewdriver and saw a notch in it so the spring hook will fit in it saw the notch at a 45degree angle toward the tip but leave enough meat to hold the load and you can pull on the handle and load the spring right into the holder Quote
NYUK Posted January 21, 2009 Report Posted January 21, 2009 on my drag bikes i would double up the springs. 4 on each pipe. Quote
