How much did your rev-box mods cost and how long did it take?
I need to have it done, but dont want to be w/out a ride for weeks! I think I might buy a new one and send it off so I can still ride.
Thanks

 

hey 300ex-treme when you put the pipe on do you have to do anthing else to motor?and if that was the only thing i did does it realy make a diffrence

 

The pipe will make a difference but depending on which one you get how much is variable. When I bought mine it had a DG pipe and muffler and I bought an FMF (cause it looked neat) and it blew me away the amount of power it had over the DG. However, I rode a friends 250x stock then put my old DG on it and was blown away how much it did. So basically, the DG added power, then the FMF added more, a lot more.
You might have to re-jet depending on your pipe. A friend put an FMF identical to mine on his 98 300Ex and didnt have any problems with it, but I have to re-jet mine. All depends on the bike I think.

 

If you send your black box in, it will take 2 or 3 weeks before you get it back. It costs $90.

I just bought a whole new black box for $190, and keep my stock one. It comes in 5 days and it's always handy to have the stock box around.
I put the stock black box back in the machine when my girlfriend takes it for a ride. It makes the power curve alittle more rideable and then see can't blow the engine by holding it wide open in second.

When I put the pipe on, I also installed a K&N filter and a Moto-Force 'open-style' airbox lid. With these parts added, I had to change the main jet in the carb to a #128. This compensated for the increased airflow in and out of the motor. What difference did it make??? In stock form I could only hit the rev-limiter (about 7000 rpm's) in first and second gear. With the mods mentioned, I can now hit it in all five gears. And the noise is still as quiet as stock. Unless I go full-out on the motor soon (doubtful) I will probably not change the muffler at all.

 

after exhaust and a K&N, I'd play with the front/rear sprockets. I've got a 00 Warrior with a supertrapp IDS2 pipe, K&N, 38mm carb. wiseco 10.4:1 pwr piston, WB hotcam. I tell you I didn't gain any speed at all, until I got a 14 and 15 tooth front sprocket. As it turns out, my motor was rapping as quick to the rev limiter as it could, the HP didn't make it faster at all. Isn't lacking horse power in the woods/open field, but at the dunes, that's why I modded mine. My buddy with a stock 99 warrior jumped up w/ no prob to a 14th instead of the stock 13 and it gave him 6mph top end a lot friendlier gear range. 15tooth was bogging down pretty bad in 6th on the stock warrior. I really think other than a pipe and K&N, is a waste of money.

I can beat a stock banshee pretty bad, about 4 bike lengths by the time I click into 6th. but in 1/3-1/2 mile he'll catch up. The high end is too fast with a banshee.

Good luck, and don't jet your carb, other than main and secondary jets. 4 strokes, don't need much done to the carb, unlike a 2-stroke to get good results.
