Wallrat Posted November 15, 2005 Report Share Posted November 15, 2005 I plan on asking my builder as well but was curious if anybody had any insight into this one. I've got a +4 stroker with a mild dune port - far from extreme porting. Along with that I'm running T5's, v force 2's, and clamp on k&n's. Although I haven't gotten my jetting dialed in perfectly yet I'm only on 155 mains at sea level and about 80 degrees. Do you guys think I've got enough room to run a single carb setup? The PWK's go up to 230 on the mains and 80 on the pilots. Basically I wanna hear from anybody with a similar setup, or a stock stroke with some extensive porting done, since I would guess it'd be around the same. Anybody think this would be a problem? I'm just wondering if it'd be impossible to jet due to the larger differences in air flow between lower and higher rpms. Crud I dunno.

Indubitably Posted November 15, 2005 Report Share Posted November 15, 2005 Yea U can do it, I've seen one of Richards ATV's drag 4mil bikes run a single carb on meth. He was only running a 38 or 39 can't remember exactly but u got it no problem. Quote Link to comment Share on other sites More sharing options...
FASTOYS Posted November 15, 2005 Report Share Posted November 15, 2005 Might talk to Jeepman380 as he has been that route! Quote Link to comment Share on other sites More sharing options...
brock_fuzzy_69 Posted November 15, 2005 Report Share Posted November 15, 2005 if you want to try such a setup matt i have a graydon style single intake and a 38 mm pwk i knew a guy who ran a 38 on a trinity intake with his 370 and it ran fine Quote Link to comment Share on other sites More sharing options...
PUSH THE THROTTLE Posted November 15, 2005 Report Share Posted November 15, 2005 I was thinking I saw a 235 in Dennis Kirk but I could be wrong. I'll double check tonight as I can't find it on the website. the mains are $1.99 a piece which is the cheapest I've been able to find for the PWK. I'm interested to see how this turns out for you.

fabricated Posted November 15, 2005 Report Share Posted November 15, 2005 you can try but good luck getting it jetted right. Quote Link to comment Share on other sites More sharing options...
rocketboy Posted November 15, 2005 Report Share Posted November 15, 2005 yo u might still make decent power... but itll never be at its peak potential ,your really restricting the CFM flow alot by running only a 2-1 on a ported stroker IMO Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted November 15, 2005 Report Share Posted November 15, 2005 (edited) too bad your not going thanksgiving, my friend has a trinity custom 5 mil from back when they were good, he runs a I believe 38 pwk with some sorta fuel injection system (injected into the carb not the motor) that is calibrated on a dyno. it increases fuel in the higher RPM range to make it flow similar to a dual carb, then again he runs NOS anyways so he might as well have that setup... So it can definately be done. I think he said he drills out his own jets too. Edited November 15, 2005 by Justintoxicated Quote Link to comment Share on other sites More sharing options...
FIRST BANSHEE Posted November 15, 2005 Report Share Posted November 15, 2005 I have a mild port stock stroke, trinity 2-1 with a 38mm. running a 220 main when it was 55-65 degrees here. worked great every where, except sixth gear in the sand, I need to get more fuel to the carb. good luck Quote Link to comment Share on other sites More sharing options...

I think I'm running a 195 with my gorr port stock stroke usiing a 35mm? Are you sure you're not bogging out in sixth gear cause of too much fuel?

jeepman380 Posted November 15, 2005 Report Share Posted November 15, 2005 I have the single carb setup with a 4 mil stroker and porting and it hauls ass. Can't really compare it to dual 35s cause i've never had that setup but it pulls from bottom to top really hard. I ride alot of trails too with no problem and I hardly ever bog. Extremely easy to jet too. I'm running a 210 main with a 56 or 58 pilot with my mods in my sig. I don't notice any bog in the sand in 6th. I've got 15/41 gearing also. I was thinking about switching to a 38 PWK to see how much of an improvement it makes over the 35 PWK. Quote Link to comment Share on other sites More sharing options...
PUSH THE THROTTLE Posted November 16, 2005 Report Share Posted November 16, 2005 Here's where you can get the 235, last three digits are the size. http://www.denniskirk.com/jsp/product_cata...afCatId=&mmyId= Quote Link to comment Share on other sites More sharing options...

I won't be in the sand again until the dunes open back up in the spring. Quote Link to comment Share on other sites More sharing options...
DUNEDEMON Posted November 18, 2005 Report Share Posted November 18, 2005 Kevin will probably try to talk you out of it, but see what he has to say. When did you get T5's? Quote Link to comment Share on other sites More sharing options...
