Thanks a lot for the speedy reply! I traded my 450 for both of these quads last night, so the information I have is from stairing at for an hour last night.

 

Now for the fun stuff:

 

"Also, I take it neither bike has porting?"

 

In all honesty, I have no idea. But to take a guess... No.

 

 

"What size single carb."

 

Again, I have no idea. Do you recomend putting this carb on both of the quads? It seems like it could be a good idea.

 

Thanks for the help! All info is good info!

Welcome to the HQ!! Your gonna love working on 2-strokes after having that YFZ. Jetting principles are the same on 2 strokes. If its hard to start the pilots are too lean or the airscrews need to be turned in to richen it up a bit. What jets are in them now?

That is a controversial topic, honestly. I loved it on my quad, no carb syncing, no one side running bad, no jetting dual carbs and it's nice and clean. My quad ran very hard and beat most and hung with the rest of similarly modded banshees with dual carbs, tuning is the key. Most will tell you that you'll lose top end and that's not true. A lot will tell you dual carbs are better, but that's dependant upon how you look at it. Most that speak negatively about the single carb setup have never tried it. Compared to the stock carbs, you'll gain A LOT more bottom end, more midrand and still more top end. Compared to larger 30mm carbs, you won't have that much top end but you'll have a lot more midrange and lowend then them. Most hardcore duners want 30mm carbs minimum, more like 33's or 35's and your talking about no bottom end. If it was my bike, I'd have a single carb on it, absolutely no question. If you plan on going stroker, then you may end up needing a set of duals but for a stock bore/stroke banshee, you can make it run AWESOME with a single carb setup, good porting and good compression.

I sure hope so!

 

I'm not to sure what the jetting is now... I was trying to get some ideas before I crack them open... I got so used to my 450... It did this, so it means that an so on.... The YFZcentral was a great place to learn and meet a lot of cool people. It sounds like that around here. In fact, a guy from there told me about this site!

 

Thanks for the info!

I was planning on making my 97 a duner. Kind of like my 450. Low stance, really reliable, and fast for a stock boar/stroke motor. The single carb might be the hot ticket. I figure, I have it, and it will be easier to dial in. The 89 I'll start building after the 97 is done. Maybe a Cub motor, or something to that nature. I figure by the time I figure out how to work on the 97 and have that thing dialed in, I'll somewhat be comfortable enough to tackle a hillshooter.

 

Again, thanks for the info, and keep it coming!

Yeah, I'm on YFZ Central too. This site seams to be friendlier. All ya get there is "search search search." Here iIve seen post after post on the same topic, and they always get answered in detail even if its been answered a thousand times.

I've noticed that... I figured I'd get flamed for being a first time poster, but the vibe is great here. I think the Central is a little bit more user friendly, but the people here are a lot cooler!

Welcome to the dark side!

 

sredish has you hooked up with about the best jetting advice your going to get. Maybe bump up the main size a couple sizes over his reccomended sizes if you find the cylinders are ported. If you pull the carb and the reed cage and look into the neck of the cylinder you'll be able to tell if it is ported. Hard to start sounds like lean pilots as my first guess.

The Dark Side... I love it!

 

It is definitely a lot different then the YFZ450. The jetting seems to be a lot more temperamental then the ever forgiving four strokes! I

Welcome to the addiction of owning multiple Banshees. You found the best site on the net for virtually anything. Hell, I've seen guys in here walk others through fixing their washing machines, dryers, pond installations, you name it. As far as the Shees, rip them carbs off, clean them real good, get a Clymer manual and write down everything in there when your bikes start running strong, i.e. needle clip postion, mains, pilots. As for dual carbs, once you get them dialed in and synced they're a snap to keep running good. If all your'e going to run is the dunes then get some porting, a few members here do outstanding work, F.A.S.T. and Passion racing come to mind. After the port go to 33-35 carbs with pod filters. After that skys the limit. Get a second job or work some overtime, Shees love you to dump money into them. Good luck.

Welcome to the real dune quad site...

I'm not going to comment on the jetting...it's hard to beat sred's advice on that.

 

however...I'll throw my hat into the carb question ring.

 

If you just plan on duning around and drag racing occasionally....yep, 1 into 2 carbs is great. Less maintenance, easier to work on, etc.

 

But, if you're going to be doing more drag racing than duning, you will be missing out by going to a single carb setup.

 

My man, you have got it made. With two shees, I'd have one for both. One for drag, one for dunes.... it doesn't get much better than that!!

Well, I've stared messing with these things. The 97 will be my duner, and the 89 will be... well soon enough! I ripped the 97 down to the frame and and motor. I have T5's, large K&N with airbox lid off, Boysen reeds, and a brand new set of STU Paddla Brats on the rear and STU Razors on the front. I've started the cleaning process and will be putting the quad back together tonight. I'm going to start my jetting at 280 and work from there. I decided against the pods for now (the K&N was in the quad, and I plan on putting the pods and Boysen Rad valves on the 89).

 

I'll keep you guys posted!

The second job sounds like a good idea! I've been spending money like I won the damn Lotto! I've heard some good things about Pasion, so I'll look into them!

 

Thanks for the info!

I really like that 2 into 1 carb. It reminds me of my old YFZ450. I think I might put that thing on my 97 and work from there. Haven't really decided yet. I have a trip to Dumont on Oct. 5, 6, 7, and 8, so I'm just trying to get this thing up to speed. I still can't start the 89, but I really just want to get the 97 running strong. I guess all it takes is MONEY!

 

Thanks fod the info! Keep it coming!

Well, I went another way. I tore the 97 down, got the cylinders honed, and got a clean up port. Put new pistons, rings, wrist pins, and bearings in along with the UNI pods, TORS removal, T5
