I already have piped, jetted and air boxed my 03 Wolvie. What is the next step that i can do to give it more oomphhhhhhh!!!!

Thanks,
Danny

 

Bump

 

Next you will need to go into the motor, if you are looking for just a little more power, just bumping up the compression will help, but might as well bore it a little while you are at it. Port the intake and exhaust while the head is off. A Web 88 grind cam is a good all around cam,it will work well with mild mods, and keep the power in the low to mid range where you need it, a race cam will let you rev more, but cost you bottom end grunt. A bore and stroke kit is available in several sizes, you can go as high as 500 cc, but most stay around the 435 - 465 cc range, much more reliable than a full race built motor. Most depends on the time and / or money you want to spend.

 

Warn 424 Select is your next move.

 

Thanks for the input BTW here is what is already on the quad

White Brothers E- Series Exhaust
Warn 4-2-4 Disconnect
DG Nerf Bars
Jetted Carb
CFM Performance Aluminum Air Box
UNI Filter
SOON TO BE INSTALLED>>>> ---- DIAL A JET

 

how much difference did u tell with the CFM airbox? and the white bros exhaust? how do u like ur nerfs?

 

it has a bit more punch but not as noticeable as a worked engine. but all in all its the worth it

 

95wolv,

I just got a set of works at steelers, dual rate no reservoir for the front of my wolverine. I ordered the ones for 150 to 190lbs rider. I weigh 170. I talked to works about setting the preload adjustment. They say 1/4 of wheel travel. Yamaha specs say front wheel travel is 7.1 inch. With the preload adj. on the first notch all I can get is about 1 1/8 or so of sag. 1/4 of 7.1 inch wheel travel is 1 3/4 inch. What have you found to work for you?

 

whitedogracer,
I am still in the process of fine tuning mine, instead of going for the recommended preload travel, I have just been riding, noting response in ruts and jumps,and making small adjustments to get the ride and rebound that I prefer. With the front, I have found keeping it a little more stiff works great, soaks up a jump just right without bottoming or pogo sticking up too quick. I am still playing with the back,haven't rode much this spring,too darn muddy, the back still needs a little turning down, a fast run through hard whoops will still make the back jump around a bit, needs less rebound, but I know I'm really close to what works for me. Everyone likes a different ride, some like sporty and firm, others want comfy, best thing is to ride and note how the front and back react, and set it to your likes. Works are a real nice step up from stock, haven't bottomed them out yet !!

 

I just went to my ATV dealer and he trired to talk me out of hopping up my 03 Wolvie. He prolly wanted me to buy a new quad from him lol. So my question to you is do you think i should go ahead and bore out my cylinder and if so to what. I plan on still using my quad in the snow for plowing so i have to keep that in mind. I dont want a rev monster!!! here is what i was getting from them without the bore


Piston 10.5:1 (no boring required)
Cam 440 Intake 390 exhaust
Spring kit.
Carb 36mm


What else ?...if there if i am forgetting something its prolly cause i dont remember.

I realize this is only upping my compression. but what i'd like to know is since i am having them do this stuff now to it...should i go ahead and go for an oversized piston for displacement?
