you loose top end. Great for trail or woods ridding though.

Maybe you did, but the fellas I ride with wish I would have. I gained a lot on the bottom and mid, serious amounts, but I also gained on the top, just not as drastic. People think you lose on the top, but you don't. Its just that the mid hits so hard that the top doesn't seem as strong as it was.

 

I am a huge believer in the single setup. If you get into some heavy porting and such, you may need some more air, but for stock internals, you can't beat it. IMO. Plus, jetting is a 30 second ordeal and it is so clean in the engine area.

 

But, to each is his own, or whatever the f*ck.

Agreed... for a stock engine, thats a good mod. When you start porting and doing other crazy things that demand high airflow, the dual is the way to go.

 

Jetting on the Mikunis is about a 2 minute ordeal :) I wish they'd have made one of the nice access holes in the bottom like a lot of the Keihin ones have. Oh well.. just 4 screws.

I didnt even like it on the motor without porting. I have never seen a fast bike with a single carb set up. I have talked to so many engine builders and NONE except trinity recomends the single carb set up. Look at patriot racing, a&s, K&t, rudy kurts, ted boyko from mission yamaha and they all say throw that piece of shit away and get some duals. They all dont agree on the size of duals though which is hard desiding on which to buy.

Like I said, "If you get into some heavy porting and such, you may need some more air, but for stock internals, you can't beat it." Most builders port, polish, stroke and yank. If you get into that, this isn't the setup for you, but for stock internals, it will really help.

 

Also, it is very important to get your jetting dialed in, I don't mean close, I mean dialed the fu*k in. If you haven't been around a fast single carb, it's 100% because they don't have their sh*t dialed in, or their setup is totally wrong. If you don't believe that, I'll prove it to you.

I ride in the sand capital of the world. I am sure that one of those guys have had their stuff dailed in right. You will gain more bottom end but in the dunes you dont even use bottom end that much. Most people have their gears ratio so close that when they shift they dont drop enough to rpms to use that stump pulling power. I can see it if you are putting around all day but the group I go with ride hard and fast the whole time and we dont drop our rmps below 5000 rpms. Even someone here dynoed their single and it lost 5 hp on top.

Well, I don't putt putt around all day, that's for damn sure, and if your talking straight sand all the time, I sure as hell wouldn't have fatties either. If your gonna build a bike for the dunes, theres a lot of shit I'd do differently, but thats not how I want my bike setup. I may lose 5hp from some other setup, but I sure as hell didn't lose 5hp from the stock carbs. On the other hand, I feel my bike does just fine in the sand, and it setup just the way I want it.

 

Like I said before, to each is his own, and thats what makes this so great, is anything is obtainable. There is something there for everyone, and not everyone rides sand 100% of the time.

Fattys are great for the dunes, and my friend has a single carb, when the tops stops pulling he just hits the NOS...swears by it...But I'll keep my dual carbs :)

For trails it absolutely kicks ass. My buddy's 400Ex used to be able to keep me in site in the tight trails but with the 2 into 1 I have to pull over and wait up to make sure he hadn't crashed. This has caused him to put a down payment on the 450r (wants the interchangeable parts w/ 400EX) so he can keep up with me. I've gone to a stroker now so we'll have to see what happens.

 

My setup is going on ebay in a few weeks because I need to go to dualies with my porting and stroker.

If I was going to sand 100%, I'd probably go to the ever popular T5s or maybe T6s.  Now NOS, I could handle that. :D

There is not a huge difference between T5's and Fattys, except that after porting the Fattys offer a couple more HP...Stock they hit before the toomys but lose 1-2 HP on top...Both are great for sand.
