Hey i just bought a used 2005 raptor 350 im wondering what the top speed is and how to make it faster? i already took the baffel out and im wondering if that changes its speed/acceleration?

 

55-60 top speed.Lots of raptor 350/warrior experts on here to give you the low down on modding.from my experience baffle does not make a real difference imo.Gearing can make a difference but it will take a while to get to a high top speed.

 

i think the top speed on those is about 60 or a little bit under, you can always change your front sprocket, +1 tooth will give u better top speed -1 tooth will give you lower top speed but will be quicker, taking the baffle out usually lets it run better unless it ends up running too lean without it, you can always pull the airbox lid off and go to a yamaha shop and buy like 2 or 3 jets of the next size and go up 1 size at a time until it runs good with the lid off and youll notice a little power gain. other than that if your really interested in making it faster its time to do the big 3, Pipe,filter,jetkit

 

alright if i were to do the pipe,filter,and jet kid what would you recomend and how much would this be costing me? i like real loud pipes im kinda new to this so im not sure whats good and whats not =\

 

Most everybody uses hmf for the pipe,k@n or uni for the filter and when you do that you gotta jet it.

 

oh iight i was lookin at the pro ciruit T-4 is that any good? and how much are sprokets do you know of any good websites i can order stuff from?

 

Pro circuit makes good pipes, but maybe not for your machine. There are a lot of exhaust mfr's out there and it's been my experience that there is no one brand for everyone. For example, HMF gives my preddy more power than others. While it may not work as well for a suzuki as say a yoshimura. Do some research, ask around here on the forum and find out what is working best for everyone else with with a raptor 350. You may also find that there may not be many available for your atv. That will help narrow down your choices! LOL! Scrambler400 is right on the money, though, do the big three. HMF does make a good pipe and is relatively inexpensive. I only paid $400 for my full exhaust. So, if they make one for you and it is comparable in power increase, then it would be a smart buy.

 

so what would you reccomend for a raptor 350? and do you know of any good sites to order from?

 

I'm also a fan of the HMF for the Raptor 350 slip-on. It's probably the loudest exhaust that you can buy for the 350 and still sound good. You don't need a full exhaust for the 350, just the slip-on will do. With the pipe, filter, and jet kit you can go up to a 14 tooth front sprocket and gain about 2-3 mph on the top speed.

I bought mine from gopartsdirect.com for $220

 

I really don't know much about the 350 raptor. I had a 660 in 2002. But, I hear the Yoshimura is great for top end power gains, while HMF makes better low or mid power gains. A full exhaust for either would be under $500. I had a yoshi on my 05 preddy and on my z400 and it was nice. Very loud and often shot flames! LOL! But I am very happy with my HMF performance I have now. It is also very loud. I like loud pipes, too!
