Works great

I've had this for about two years now and I've had no problems with it. It does make a difference in power and top speed.

Not so happy....

the big gun rev box I got and installed in my quad did not work for some reason it made my quad run like grud, so I called motosport to see what they can do for me and some guy named Isaac said "it's a electronic device so we can't take it back call the manufacture see what they say".... sweet thanks

Waste of money

i have a 2009 TRX 450er , i plugged this box in and it literally did nothing for me. i felt absolutely no increase in power and my top speed was clocked actually a little bit slower, from 80 to 76. maybe i just got a bad box, but i am not pleased.

Bad luck

pulged it in & it worked great for about a month. then my fan stoped wotking & my indicator lights didnt work. i put the old one back on & everything worked again... MOTOSPORT is a great company to deal with. they got it warrantied by big gun & being the only differance was the higher rev limiter i took the credit towards some other parts.. it cant hurt to try it. mabey you will have better luck than me....

Best thing to get

i got a 05 400ex and when i bought this i plug it right up and like other people say the first ride you dont really feel a difference but once you ride it bout 2 or 3 times you feel the difference it did pick up on the top end but it really picked up mainly in 2nd and 3rd.... my 2nd guy wheelies i use to have to pull back some to pull it un but now it comes right up with no problem and with this box i took out to a friends far with a bunch of open land opened it up to 5th and it was still pretty easy to stand it up in 5th. great buy if u plan on racing buy it, it will help out a lot...........

Works great

An ignition box was the next step in the evolution of my raptor, and it worked great. Plug n play, and the quad even starts easier.

Great Buy

I installed this in my 06 raptor 350, within 5 mins. Super easy to install, and what a huge difference you see. Huge power increase! Takes a bit for it adjust to your system, but def worth the extra cash rather than buying a cheap model. Can always trust Big Gun.

i putthis rev box on a 2001 400ex it was very simple to do it did give me a good top end increase and a higher rev limit but the first ride will not reveal anything... your motor has to learn the new cdi first other wise it will run the same the you will feel the difference
