1984 ATC300R Fooler build

[RIDE-RED 250r]

Well, IMHO, the carb is just one component of many that contributes to the power curve characteristics of your engine. Maybe a 35-36 would be better suited to your build being that you are going for a trail port. I don't think its going to be an extreme night and day difference though.

You could always get a 36 and if you don't like it, get it bored to 38.....

That stock waterpumper I was running my 38 on was stock ported too. Only mods on that engine were the bolt-ons: FMF Fatty pipe and Powercore silencer, reedblock, CR head gasket mod. It had terrific mid-range but ran out of legs when getting to top. Probably due to the high compression setup with the thinner head gasket.

Oh, and I believe you can get a quad vent, non-AS PWK too. Been a little while since I looked at carbs lately... My next carb will be a 40.5 PWK for the big bore, and the 38 thats on the big bore now will go on my sleeper 250

I guess another thing to consider is that he could start with a 38 AS and if he didn't like it it would be easy enough to sell.

This is true.

Yes the liquid R's vforce fit perfect on the 81-84 250r, that is what I use on mine. Getting an intake to fit a 38mm carb isn't easy to find either.

look at pages 220 thru 223. universal intakes are on 223m might be something there.

true, i thought about grabbing one of these also. BUT would the tilt from this intake for the liquid R's effect the ability to install the induction tubing to my intake box.?.... that was a major concern for me as i really want to run this with a box since it will be in the trails / water possibility's.... last thing i want to do is suck in some water and deal with that...

That I am not sure of. I have one on my waterpumper and it works just like OEM to connect to the airbox. I am not sure if the Foolers had a different angle or not.

thats a potential good situation you found right there barnett, i am wondering if this would work out from page 223
FL250 Odyssey 77-84 Rubber Flange M-VM-36-200K 36, 38 each 002-054
too bad they didnt have a darn picture of it, i no the fl350 intakes are direct swap for the fooler's but i dont no about the fl250's
also on the next page there are the UPP intakes available on page 224, but they are for the liquid R's and again the question of the tilt in the manifold comes into question?....
ATC250R 85-86 PWK 38 - 39mm each 005-831

I actually sent an E mail to UPP directly, according to there website they can make custom pieces. i wanted to see if they could make me a custom intake for the 81-84 for a 35-38MM a couple days back but i have not heard back from them as of today. if i dont here from them by Monday i am going to call them directly and see if they can make me one. they say they can make custom pieces soooo..... i even said in my e mail that if needed i could send them the stock intake that i have so they have it as a refferance while building the larger one for the 35-38.... but of course i have yet to here from them..

the foolers are straight out from the engine, NO angle what so ever. so that has the potential to be a serious problem! lol.....

That being the case I agree and would not use the intake I posted the link to

[bigdaddyvw185]

we are thinking alike, that would have been a sweet solution tho ill tell ya! lol. i needa get in touch with UPP industries directly and see if they can make me a custom one for the fooler's.

here is the link for there custom area, not alot to see but hey...

Here is mossenbergs number. Someome from s.com gave this too me. They supposedly still make a intake, I ended up finding a old old school one for my 38mm carb so I never gave the number a shot.

(856)435-1977 they are out of new jersey

Let us know if it works

[bigdaddyvw185]

thanks!, i will give them a call on monday. that would be sweet if i could get an intake and a reed kit, hopefully it works out.
