How much hp does a head shim rob from the engine? 5% 10% 20% 30%???? I've read numerous posts of guys saying no way on the shim. Is it really that noticeable? I have one and honestly I can't really tell the difference. So really, what is the drawback? I guess if I was racing and wanted an...

For those of you that have the ZBroz front end installed, be sure to check the nuts that secure the spindle to the a arm. Twice now I have had that nut come loose and fall off while riding. both times at high speeds! The nut was torqued down tightly and secured with RED Loctite both times and...

I recently changed my BOV spring. Before I changed the spring I used to hear a Swooshing sound when I would let off the throttle. After changing the spring I now hear a fluttering sound, kinda like the sound you hear when you act like a machine gun. Does this mean the spring is too tight...

My AF numbers seem to be pretty good at idle when I initially start the sled up but if I run the sled and start producing boost, after I come to a stop my, my AF at idle jumps to 16-17 and even goes past that and shows a blank reading. If I leave it the sled usually stalls but if I blip the...

I just got my supercharger back after last years meltdown and was able to get it out on the trails this week; riding in the UP Michigan. The pulley combo(27T/28B) I am using is supposed to be producing 8lbs of boost but I am only seeing 5-6. I have an Ulmer clutch kit installed which was set...

So what is it? I've read a bit a bout it and the general consensus is it a great skid. Why? They no longer sell them and parts for them seem to be difficult to find. Are the worth pursuing? An 08 Nytro with a ZX2 or a new Viper? I'm actually really happy with the Nytro with the Star...

Are these the correct part #'s for the skid bearings? Rear axle #6004-2rs, idler wheels #6005-2rs, and upper idler wheels #6204-2rs.

I'v been looking for a replacement wheel to the marginal snow wheel kit and until recently have had no success finding one. I've asked on the forum here and nobody seemed to know or didn't want to offer up the information. Well I finally found a replacement wheel in the PartsUnlimited catalog...

I'm looking for the size of the coolant hose so I can add a hose adapter with temp sensor. I found a nice inexpensive setup on Amazon from Koso. Sensor adaptor plus thermometer is only $66...

I have not had any issues with a lithium battery(Shorai) in cold weather. For those of you that have used a similar battery, what are your experiences with cold weather starting?

I really dont' want to pull the front end off of this sled. Can this be installed while it is on?

Does anyone make an aftermarket oil tank for the Nytro? If I can't get mine repaired I'll be looking for a replacement.

I need to install tie rods but need help with it. How far does the tie rod screw into the inner joint? How much of the outer joint should the tie rod screw into? Do the nuts on the inside but up to the tie rod? Any help installing and adjusting would be great. Also, I read somewhere that...

New. Never used. Free + shipping.

Earlier in the day I left the key on and liked the battery. Jumped the sled and ride about 25 miles. Pulled over to get something from bag and shut down. Started up and got about 1/4 mile down ride and sled stopped. Tried to start but no luck. Sled turns over slowly, tries to start but does...

After installing an MPI supercharger I have fouled two sets of plugs already. I'm running the CR10 plugs instead of the stock plugs. Anyone else have issues fouling these plugs on a boosted sled?

Instead of purchasing a 4th wheel kit for $50, can I simply use the existing collar and cut a small piece out of it and use a spare wheel for the 4th wheel. Looks like I could get away with cutting an inch out and use the two remaining pieces for the new collars.
