Sure it's not just vibration from the motor when you rev?

We will.

that should be a good place to start. You might need to go up or down some depending on your elevation, air box lid on or off, and other small factors. Jetting is easy. Set your needle in the 3rd position (just as a starting point, 'cause I recommend the 4th) and then set your main jet. Do a Wide Open Throttle test, kill it with the throttle pegged in 4th or 5th gear. Coast to a stop and check the plugs, should be a dark brown, any darker and it's rich, any lighter and it's BOOM, too lean. Once the main is set, adjust your pilot for good throttle response, and idling. When that's set, play with your needle, move it to the 4th position and see how it runs, starts and all. You should be good to go after that. Start with the suggestions above and see how it goes. One thing, you get richer as it gets hotter, because the air temps go up and the air is less dense. You get leaner in the winter, because the air gets cooler and more dense. Remember with Jetting, keep it simple and don't overwhelm yourself with the big picture, take it one step at a time.

If your butt starts to hurt, don't bother asking questions.

Forgot to mention that. Great tool, yahjew has one too...but screw yahjew... Hmmm, I didn't know that. Something to look into.

they're all right about Vforce's recommendations. However, I would make sure to check the plugs afterwards. Even if it's running good, you may be able to squeeze another main jet size afterwards, heck maybe two. Remember, fuel makes you go. If you put on the reeds and are able to squeeze another main jet size, then you should technically have a little more power. The added power is definitely worth the time it takes to check. Take pipes for instance, pipes help on power a lot, but some of that is due to the increase in jet sizes. Later.

The left cylinder, with stock carbs especially, can have a tendency to run a little richer on the left cylinder. Has something to do with the choke on the carbs. There could be a small air leak on the right side causing it to lean out some. If you've checked it all out and can't find anything then don't worry. The one tan/brown plug should be a darker brown color, if that's the case and it's running good, then just leave it, if it's too light, then maybe jet that carb a tad richer. It's not unheard of to have one carb jetted a tad different. Just make sure that's the problem, and it's not masking something else. Here's a good article on reading plugs. Reading Spark Plugs

that's about as much as anyone can say. On your 21st birthday, you can do no wrong. Get drunk Get laid Get more drunk Get laid again Party some and, hell, why not, get laid again.

Now where do you think he's going, bet it starts with a B also. Bye Bye

First things first. Don't let it overwhelm you. Get your main set first. Period. Once your full throttle performance is good and the plug is nice and dark, then begin dialing in the pilot jet and needle for your low and mid throttle response. Remember one thing, one clip on the needle is equal to a half size on the main. So you might set your needle in the 4th clip and set your main, if it turns out the needle is too rich, then you know what to do. Also remember, one step at a time, don't bother with the whole picture, the main is, well, the main, do it first and the rest will fall into place. Scott

and they're pretty pricey; close to 6 bills.

pretty much sums it up.

Yeah, I haven't had one for over a year. I check the rad, whenever I can, but shee does just fine.

All the internals of the 33 and the 35 are absolutely the same part. The jets included. If you want to get technical, there's a nut and a brass idle adjuster that the 33 doesn't have, but everything else is the same. And other than 4 or 5 parts the 33m to the 39mm are the same. If you were to order parts, it wouldn't make a difference which is 33 and which is 35, the only difference is the bore size.

well, it cost you your time, don't sell yourself short. i imagine one of these days, i'll give you one to play with, but I'm just too content at the moment.

They're good carbs.

nope, not gonna do it.

Probably just the outside conditions. Humidity and air temp can play a big factor on carb'ed engines. One day it's great, then a front moves through and the humidity goes up and it drops 5 or 10 degrees and that can cause you to maybe need to kick it a few extra times due to the slight richening of the mixture. Don't worry if it's running good.

Measure the inside with a gauge to know for sure. They are very similar carbs with all the same parts, it's hard to tell without measuring. Jeepmans got you set on a good starting point.

Led, glad to see you made it through. I went out Fri. till 4 am. Got so drunk I must have kissed Mrs. Porcelain at least 4 times. The next morning was so freaking awful. Made a couple more visits to Mrs. Porcelain. I had an hour and a half drive, and was not looking forward to it. I actually had to stop halfway to puke in some truckstop shitter. That was wonderful. My bud was getting some fries and a coke and it just hit me, only place to go was that god awful shitter. Fun times man. Although, I can't hang like I used to.

Hmm, what a predicament. Does he have your money?? CEJ has a good idea, although, I'd be happy to send you a call tag.

I wouldn't play with your plugs. That carbon and soot is jetting not plug heat. Your mods won't have the need for a change in plug heat. If it's running good, leaving it alone might be the best thing.

I agree. Get rid of the toomey needle and go back to the stocker, 4th clip might work good depending on your airbox mods and where your at. Just remember your playing with Toomeys and your low end will only be sooo much.

At the very least, I'd replace the stock impeller just for the fact that it's a plastic hunk of waste that can break at any given moment. If your worried about losing hp, however little it may be, you can cut a fin or two off of the PD impeller. Also, for overheating, run Engine Ice coolant, it will let your motor run quite a bit cooler than with standard antifreeze. You can get it at RockyMountainATV.com, just type it in the search. As far as your pipes getting red, that sounds like a jetting condition, your pipes shouldn't be glowing like that. Get your jetting squared away, replace the impeller and replace with Engine Ice, and your overheating worries are gone.
