Okay, How would I go about widening it, and improving the shocks, I dont have an extremly small budget, But i dont have a ton of money, Just anything better than stock? What would you recommend. And what does replacing the jetting exactly mean? And what does an Anti-Vibe stem do? I would really appreciate if you could help me out with those questions, Thank you.
You can use aftermarket a-arms and an aftermarket axle to widen it. Or you can use spacers. QM actually runs a kit that moves your mounting point out instead of replacing the arms (I believe?) that's pretty cool.

Improving the shocks on a 660 basically means replacing them. Aftermarket shocks are great, but YFZ450 shocks are a good budget shock setup ($175+/-) that require minimal modifications to the stock arms. There are many threads, including a sticky on this.

I run a g-force extended/adjustable axle i got from Tech Quad Shop for about $200. I've been very happy with it.

'Jetting' is referring to your carbs. You'll want to make sure the proper size jets (main jets and pilot jets) for your modifications/etc. Along with changing out jets, there are some other things to be done to setup your carbs properly. Check the 'Carbs 101' thread that's stickied :thumbsup:

i run +2 arms with yfz shocks...and a durablue eliminator rear axle. It was pretty the much the first thing i did. IMO the BEST upgrade i have done yet. I think it'll make you quicker because you are more stable when turning, and the shocks are a must if you plan on doing much jumping. With my +2 arms, my old pogos would bottom out when i came down from a hard one. I'd get the front to scrape in the gravel. Dont do a slip on exhaust, go for a full. Also get rid of the junk air filter and get a clamp on adapter. This is not only for power but reliability as well. They can let dirt in. Dont forget about tires either...they will make a difference.

For performance you should change the exhaust, change the air filter, and re-jet the carb. For handling I would get wheel spacers all around and flip the rear link. Oh yeah and get some dfferent tires.:D

Can I take it to an Official dealership, Theres a power Yamaha by where I live, to get the Carb re-jetted? Do you know how much that would cost? I will probably go with a G-Force axle also, Heard only good things about it. Really want to look into Elka shocks to? What do you think about them?

Learn to jet your carbs yourself and get familiar with them. This is invaluable to a 660 owner :lol:

I don't know what they charge, I assume at least $60/hr shop time. This is relatively simple, and something you will end up doing many times over the life of your bike more than likely.

Along with being able to jet your carbs correctly for your mods, being familiar with them will help you solve many possible issues that you may come across in the future. This will save you time, money $$$ and frustration, I promise...

And remember, come here with any questions you might have. Nothing too small or simple, there's a lot of awesome knowledge accumulated here on the 660. :thumbsup:

you want a flux capacitor, then a yellow power band, maybe a muffler bearring and then go with the titanium piston return spring.....but make sure you wash the piston return spring in a bucket of steam before installation.......[/QUOTE Whare do you get a BUCKET OF STEAM in January Ontario?:rolleyes::rolleyes:

Have you seen this? is there more than one occacion?

Anyone else seen this.
I'm about to install my spacers.
I just bent my stock rear axle about a month ago with +2 spacers. I was cruising in second (with the 14T on) in some tight woods. I got on it for a second and ended up flipping because it was on snow and the quad decided to fish tail a little to much. I wasn't going that fast and the quad only rolled on to its side. But I felt like I was riding a horse home because the axle was bent at like a 45 degree angle. I had to drive through three creeks up to my shins to get back to my buddy house! Now i got my g force axle and all is good:cool:

And to answer your question yes elkas are awsome shocks... But not really necessary unless you are going to be racing or something like that. You will probably be better off getting some yfz shocks and having them revalved for your weight and riding style.

I did it on my old Honda. Yeah it hurt a little, it almost ripped the whole top of my foot off. You could see bones and everything.

thats sick LOL, the one and only time i did it i wasnt going real fast but the jump was uneven and it threw me off balance so my foot fell off the peg when i landed and i ran over my whole leg and it stalled out near my groin, which was lucky with the mudlites on the back LOL, but i thought i broke my ankle.
