Well I think I am going to take the plunge and buy a HMF exhaust for my P650 any complaints from those who have them on their bike. I don't want something extremely loud just throaty and deep. Also going with the snorkel, jetting, filter, and red and black spring. Any feedback from those who have these mods would be greatly helpful. I am kind of questioning myself on the red spring would like some feedback on that as well. OHH and I almost forgot the CDI when it comes out

 

All are good mods, EXCEPT, for the red(drive)clutch spring. I ride the same type of terrain that you do, IMO you will not like the red one. I recommend ONLY the black (driven) spring.

 

Hey thanks for the tip I have decided against the red spring

 

couga21-- You are welcome. Check out nyroc's 650 website in here. LOT'S of good stuff. He knows a ton about the P-650.

 

Couga21,

Regarding the HMF slip-on: It is DEFINATELY throaty and deep, but it is also DEFINATELY loud.....and I LOVE it! (Actually, I didn't realize how loud it really was until a buddy installed one on his P-650 and I had a chance to ride behind him.) But then again, I guess "loud" is a subjective thing, and what's "loud" to me might not be "loud" to you. To bring some objectivity into the discussion, check with HMF on the actual decible reading for their pipe. I inquired before I purchased mine but forget exactly what they told me. (It was either 9.5 or maybe 19.5, or something like that.) All I remember for sure was that they reassured me that it was only marginally louder than stock, but I think they stretched things a bit when they said that!

Good Luck, and you won't believe the difference in performance after installing these items on your Prairie. HOLD ON TIGHT!

 

I like the red spring. I suites my style of riding but it isnt for the faint of heart. It just takes some getting used to thats all. Most people say they dont like it but really havent even tried it. NO, Im not refering to you trx450 [img]i/expressions/face-icon-small-smile.gif[/img].

 

So what exactly does the red spring do? I was under the impression it raised the engagement point of the clutch.

 

K.O.D.--- I was told by nyroc, that the red spring would not suit my riding style and terrain, as I get into some tight, technical,steep woods sections(about 70% of my time is spent there). The rest would be fast fireroads, or fast ridgeback trails. You are right in that: I did not try it for myself. No offense taken. Guess I decided to "throw" the money at something else for the bike!

 

Yes it does raise the rpm engagement.

Thats true trx450. If you need to move in inches the red spring is not for you. I dont ride rocks so Im not worried about that. I ride tight technical woods and the red spring can be manipulated for that. Rock crawling is the only place I can see the where the red spring doesnt belong.

The red spring is like riding a manual clutch and popping the clutch. It really takes off. BUT, with practice and knowing the sound of the rpms you can tell when it is going to move. One thing about the red spring is its only $19.95 and is ten times easier to install than the black one. With the converter cover off I can have the primary "RED" spring changed in 5 min.

 

KOD--- I may TRY IT. But still am skeptical, as to whether it'll fit my style, terrain. Sounds like it might be compared to "coming up on the pipe" with a 2-stroke. That won't work for me. I should keep an open mind, though. Anyone got a used RED SPRING for SALE??????
