What size carb should I get?

[Blaster8821]

This weekend I went to Silver Lake with my blaster and was a lot more powerful than it was before after having work done by Ken; however, my buddy has a banshee and a YFZ and let me take then for a spin. the YFZ was cool but I'm a 2 stroke guy, took the banshee out and fell in love! I have so much into this baster that I cant just sell it so I guess next is a bigger carb!

I have a high compression head, bored 1 size over, ported, fmf fatty and turbine core II, v force 4 reeds, K and N air filer and an open air box.

I need recommendations on what brand and size carb I should get? I'm mostly a dune rider but sometimes switch it up and trail ride. I am not trying to turn this thing into a drag bike, I just want it to be a fast, well handling/running sports quad.

34mm carb I would think would be to big but I could be wrong. Looks like I can get one on ebay for about $180.

The FMF pipe will work no better with a larger carby.

It is a low/mid pipe which favours a small carby!

First of all what pipe should I get if I get a bigger carb? I had Ken do my engine work like I said and I was having jetting issues but felt I got it right this Friday. my plug chop looked good and my plug that I ran all weekend looked good! fires right up and idles good etc. When I was at the drag strip at silver lake my friend with another blaster and I raced down it about a half dozen times and he won half of them with a bone stock blaster. My dad says I should be blowing him away. I've been riding for years and I don't miss shifts very often so I know somethings just not right. Leak tested 3 times in the past month and its good. did it last week too. this is my plug chop and plug I ran all weekend.

What pipe should you get...

Anything right bend or a toomey will work great with a bigger carb. but good luck finding a right bend!

to be honest i have no idea. the stock photo (every one on ebay) shows a right bend

i dont know that anyone on the forum has one?

Don't know where you are in the Murder Mitten here's one in Nasty Hatchett : http://saginaw.craigslist.org/snw/4962420423.html

X2 on the SST, I know it's not used much on Banshee either. And at least on Banshee has it's own silencer, as I think it does with the Blaster, i.e. won't mate up with any other silencer.

Fat Bastard would be another, though just as hard to find.
Might look into a Shearer : http://www.farmandsandtoys.com/partdetail.asp?partid=350 might find it for little less elsewhere.

I've been happy with the fmf system and don't really understand why the Toomy system still being a left bend would be better than the fmf by that much. almost looks the same shape as the fmf too.
I do understand that the position of the expansion chamber does make a power difference but the fmf wont allow a bigger carb to do anything?! I just don't want to spend another $500 on a different pipe that wont do anything much more. Pulse I have to try and sell the fmf that's not even a year old.

i run a 34mm pj with my fmf fatty and it works just fine. it gave me alittle more topend and a noticable power everywhere else. i feel the fmf fatty is more of a mid range then a low/mid pipe. here is what duncan racing says about a 34 pj for a blaster

I'm happy with a blasters top speed. I just want power when i'm in the sand. What mods do you have on your blaster and jet size with elevation? I need to get a close guess so I don't blow it up lol

 

[MURPH]

Vitos 240 big bore , fmf fatty ,34mm pj carb 48 pilot cel needle on bottom slot, main is 172 now but im going down soon because its getting warmer at 18ft above sea level

 

[Blaster8821]

Thanks! I think I'm going to be way different than you being a stock size but ported and being in Michigan at 850 feet.

 

[MURPH]

U will probably need the cel needle, 48 pilot will be close main I would start at a 162 and work my way down but that will probably be really rich for u but better safe then sorry

I called Duncan and I gave them a lot of information to get my jetting close on a new 34mm PJ. The other quick question is should I buy the $300 air box from Duncan or get the CFM one on ebay? I was reading that the CFM one is great quality but doesn't mount good?

 

[Blaster8821]

I wish there was a way so that I wouldn't have to cut my rear fender because its in such good shape and original to the bike.

 

[MURPH]

Dont get that one from duncan all it is a trx250r airbox I got one on ebay for $30 .. I would go that route or the cfm

I have a white rear fender already cut for the cfm airbox. It's not in the best shape. But if you wanted to retain the original I could part with it. It has a few cracks.
