Hello all! Awesome forum. I just bought a 450 (have owned a stock 400 for 2 years) So as the story goes I was pretty happy w/ the power but wanted some more lower end (by the way I'm 250) So I installed a Dobeck programmer, a pro design intake kit and a slip on two brothers M-7. Well needless to say I was not so stoked when I go to the dunes for the 1st time w/ the mods and was getting beat pretty good by other stock bikes (2 different stock honda 450's and a Suzuki) The first thing I noticed when doing the adjustments is that at the full throttle it seems to get there quick and sputters. I ASSume this just might be the rev limiter? Didn't really notice that prior to mods (didn't really F.throttle my bike like that either) Wanting to make sure it was not just the way I was making the adjustments I reconnected the stock wiring. No real noticeable difference. I did swap bikes w/ my buddy honda 450 and he raced mine and at take off I cleared 2-3 feet of air in the front where mine stays down so I know weight is not the whole issue and I can beat him. I'm looking at the intake and wondering if that may be my issue? I have no leaks at the boot but wonder, it has a sock that goes over it (pre- filter) and the directions call for the stock air lid to go back on? Is that right. I seen some of the mods w/ the LTZ intake boot and wonder if that and the air lid off may make a difference. I also have been thinking about a sproket change but still think the motor should be pushing a bit more. Thanks for your time and any advise in advance. Oh and one other thing, I ride 1/2 mud and trails and the other 1/2 in the sand.
