jetting?

it has 3" rear wheel spacers right now...

Just my $0.02, but I wouldn't spend a dime on anything for your new quad until you eliminate the wheel spacers. They are dangerous for you and for others around you.

they are very easily eliminated, remove them and get regular wheel studs again. almost free if you dont include the price of wheel studs. I dont even remember if they are the full bolt type, I know the ones they had on their 300 was one bolt that went through the hub, through the spacer, and through the wheel, then a nut.

and considering you use a grade 5 or even 8 bolt? what exactly is the danger? I can see that having the wheel 3 inches farther out, on an original axle can put more leverage on the axle during a hard landing and possibly break an axle easier, but Ive seen people break almost every kind of aftermarket axle at one time or another.


but I dont see the wheel spacer itself being more prone to falling off than just a wheel falling off? and it seems way to thick to be prone to just cracking or failing somehow like that. but I just really dont know the exact reason people dont like them?

front wheel spacers, yeah, i can see all the problems/danger from those right away.

A bolt is designed for clamping strength, NOT a side load or bending load. Extending the width of your axle with 3" longer bolts (wheel spacers) puts too much bending stress on your longer studs, regardless of the grade bolt used. You WILL either bend and brake the longer studs, brake the ears off your hub, or brake your stock axle. It will happen, the problem is when.

Sorry to tell you the bad news. I know you want to spend your money on other things for your new quad, but even though it might not have the *bling*bling* or performance factor as other items, spending some money on ditching those wheel spacers ASAP is the first thing I would do. Safety isn't something to ignore....especially when you are going from a 300ex to a YFZ450.

its not really that big of a deal, as it isnt going to really cost anything to get rid of the wheel spacers, so I can still get my intake and whatever else.

I do see what you mean about the shearing of the bolts. too bad there was nothing machined/cast into the hub where the spacer had to match and fit sort of like a puzzle to keep it locked in and the bolts did only have to worry about clamping and not have any forces against them to shear off.

and about the 300ex to a YFZ450, not sure if you mean in general since ones faster and now can be more dangerous wrecking, or just me stepping up in bikes, because the only reason I have this 300 is I moved, and the 460ex I was riding up there was my girlfriends dads, and now I had nothing to ride. even when I had my R1 it didnt take long for me to want to go faster and get there faster. if you ever known anyone who is never satisfied with the power their machine has, thats me.
