Im not going to screw up my quad, am I?

[hondardr4life]

This winter, my grandpa and I are going to put in a wiseco 11.1 piston (stock bore), stage 1 webcam, barnett clutch kit, did timing chain, and an fst oil cooler. If I do this right and then break it in right, how often will my quad break down? I dont want to jepordize my motor's dependibility, just get a little more power out of it. Also, do I need hardened rocker arms, and HD valve springs with the stage 1 cam? I have heard that I dont, but what does everyone think?

Should be very dependable and last all season with mods mentioned. Hotcam doesn't need springs and hardened rockers, making it more dependable.

[devildriver422]

with that setup, you should have to rebuild itabout every month or so...





nah you should be fine, with the webcams i think you need the HD springs and hardened rockers...just be careful with the clutch and oil cooler you gotta tapyour head which can be very bad

[hondardr4life]

You only have to cut an oil line and tighten a few bolts for the oil cooler. As for the web cam they reccomend hardened rocker arms with every cam, but I doubt that I need them because everyone says that I should be fine with with stock arms and springs.

What do you mean by last "all season" I am hoping that it will last for 3 or 4 years with that stuff.

[Destructo]

their talking about racing, racing a motor destroys them, running wide open all the time.

If your just riding it like I do you will be fine, it will last a long time.

I wouldn't do any mods to make my quad less dependable, I like it stock just the way it is.

[hondardr4life]

So would you not reccomend the mods I am planning on doing? You also haveto remember that I ride with a lot of big bore quads so I just want a little more juice so that I can keep up a little easier.

[redrider311]

i reccomend them.. your gonna need to run atleast premium gas.. i dont reccomend anything lower.. and youll be fine for a good 3-4 years

[hondardr4life]

I never run anything less than 93 octane. With these mods I am going to start running sunoco 94 octane ( not much of a difference but it doesnt cost much more at all)

[drifterx]

I was thinking of putting the 11:1 stock size piston in mine too. I ride mine fairly hard, would i have to rebuild it very often with an 11:1 piston?

[honduh440]

i run nothing but motocross and sometimes sand dunes i got just under 2 years out of my piston

[hondardr4life]

But you also have a 440 big bore, that will take down the life a good bit.

This is driving me insane, all the old people in my family who used to mass with snowmobiles all the time are saying that I will be lucky to get 1 year out of my engine with the stuff I want to do. So I am thinking that they are wrong beacause thay messed with a lot of 2 strokes. I am pretty sure that I am going to do these mods. How much of a difference compared to stock will I feel?

[250exen]

you should be fine fo atleast 3 years if not more if well taken care of. most of the snowmobiles are 2 stroke and need to be rebuilt more often then 4 strokes....

[hondardr4life]

Ya, thats what I figured. I know that 2 strokes blow up a lot more often, but i didnt know anything about snowmobiles.

[LazeR]

Im pretty sure with those mods it will last you at least 2 years, your not boring, just adding more compression, most ppl bore it and add more compression, and theres still last 2+ years, so i would say as long as you take care of it, change the oil and what not it should last you a long time!

[1fast400ex]

i would recommend staying away from barnett clutches go back with stock honda much more reliable.

[hondardr4life]

Really? I have heard good things about barnett.I have had a bunch of people reccomend them to me because I am going to a higher compression that I should have more of a heavy duty clutch.

[1fast400ex]

i went through two sets in 2 weeks drag racing third set went back to stock honda and have had no problems. ran the original clutch 2 years. i heard barnetts were good to. thats why i tried them.

[hondardr4life]

wow, thanks for the advice. I will look into stock clutches.
