XxMeltIcexX Posted October 3, 2007 Report Share Posted October 3, 2007 I run 35pwks on my stock stroke ported motor, are you calling me a yehoo? If you had a stock ported motor then id see it being too big. I wouldnt go any bigger than a 35, but I like the piece of mind knowing that when I go to a cub, I wont have to upgrade my carbs. Throw those carbs on there man, jet it, and rip. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted October 3, 2007 Report Share Posted October 3, 2007 (edited) Apparently you got the carbs waiting to upgrade the cylinders then. I have seen those 34's and 35mm keihins on alot of ported 350 stuff. LRD, JSD, JD, K&T, Patriot Racing, ILR, Hoffman, Duncan, Jet city, Jaws, Redline, Packard, Trinity, RDZ. The only bikes that ran exceptionally well and fast from what I saw were the Redline, K&T, and The packard motors. Those bikes were full on hill shooters though. Two of them ran side pipes even. It seems like a lot of guys bolt them on just cause they think they can. When I modify or build a motor, or setup a bike. I try to get the person to spend the money in the areas where it will make the improvements he wants. I dont really recommend doing stuff cause it is cheap or it will get him by. My cousin does that shit and it always comes back to bite him down the road. You guys own banshees, just buying them is an agreement to open up your pocketbook just for general repairs when you ride. If you decide to do upgrades, it cost money to do it right. Run the 35's if you want, I dont know what to tell ya. You wont try smaller duals or a single, so you wont ever know how it would have run. From my experience, no ported 350 shy of a drag bike needs a set of duals that big. Edited October 3, 2007 by Snopczynski Quote Link to comment Share on other sites More sharing options...
shanYE west Posted October 3, 2007 Report Share Posted October 3, 2007 I thought Jaws only built custom pipes? Maybe I'm thinking of a different Jaws performance. Quote Link to comment Share on other sites More sharing options...

I dont even think they have a shop anymore. Quote Link to comment Share on other sites More sharing options...
Justintoxicated Posted October 4, 2007 Report Share Posted October 4, 2007 (edited) Putting together a motor and already have a pair of 35pwk air strykers laying around. It would be cheaper to buy intakes than a different carb setup. Mods to include: +4 timing shaved head lightened flywheel Pro circuit pipes afternarket reeds dune port Too big or will it work decent enough for duning? want to trade for 33's pwks + cash? My carbs are too small and yours are too big. Just upgraded to 4mil cub. I think you will be ok with 35's but you will have a bit less snappy response. The 33's were awesome on my Passion 12-port dune stock stroke. I woudl not have gone any smaller although 30-33 is probably the sweet spot.

JET 99 Posted October 4, 2007 Report Share Posted October 4, 2007 i have 33 pwks per builder recomendation... .020 bore stock stroke motor. 20 cc domes. +4 timing and his all over power port (thats what he called it) it has plenty of bottom end compared to stock even with t-5's so i question them being way to big.

Hilarious Posted October 4, 2007 Report Share Posted October 4, 2007 I gotta add my 2 cents to this thread. I have 35 pwks on my 4mill dune port and I have shearers and the mother fucker runs damn good and plenty of bottom, mid and top end. I dont see what the fuss is all about. Put the 35's on there and see how it does. :thumbsup: Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted October 4, 2007 Report Share Posted October 4, 2007 although i dont normally agree with snop, im with him on this one... i think those 35's are too much for s 350. i dont remember if he said what pipes he is using either... but like always if your intake, porting, and pipes are not working together your loosing power. just becasue your bike "runs good" with them dosent mean your getting your maximum power delivery from the motor across the powerband. i say ditch them and get some 30's unless you ever plan to go to a bigger motor then keep them.

I assure you that I do not have some mix matched parts (components) on my banshee. My engine was set up and ported for the 35's on it and I'm pretty sure everything is working in harmony. And yes, it runs good. IMHO it should have come this way straight from the yamaha show room floor. :laugh: Quote Link to comment Share on other sites More sharing options...

JET 99 Posted October 4, 2007 Report Share Posted October 4, 2007 4mill is not a 350cc motor. mine still is!!!!!!!!!!!!! v3's, boss intake, NOT A DUNE PORT and runs pretty damn good for a +.020 clean up bore... on 33's pwk (so without throwing names) im gonna go with someone who puts his name on the reputation of what he does for a living... he know what he is talking about or he wouldnt be so popular Quote Link to comment Share on other sites More sharing options...
wesw Posted October 4, 2007 Report Share Posted October 4, 2007 Now a dune port 350 will show no loss of power with a 2 into 1 intake. Only time you would see a significant loss is on a top end or drag ported motor. And obviously a motor with bigger bore or aftermarket cylinders. So, watch what you tell people I say, cause thats not what I said. Lots of people dont like the 2 into 1 for two reasons. About 75-80% of the 2 into 1 intakes with pwk's I come across on bikes have the wrong jetting and needles in them, and change the power delivery alot once we play with them a bit. the same can be about any bike, jetting can cause a bike to run like shit. i personnaly think 2-1 choke a motor down, why have one input when you could have 2. just my opinion yeah they work but so do duals. again to the original poster i would try them carbs out, i hate air strikers but best of luck with them. if you can work the jetting down it should run good.

Hilarious Posted October 4, 2007 Report Share Posted October 4, 2007 4mill is not a 350cc motor. I thought we were talking about 35mm carbs on a dune ported stock cylinder setup. :shrug: My bad, as I have a 64.5mm bore with and extra 4mm of stroke. What is that, like 370 somthing? Technically, I doubt there are any true 350cc dune ports here. Dont most builders bore the next size or at least do a hone? They may have a stock stroke but not a true 64mm bore.

Snopczynski Posted October 4, 2007 Report Share Posted October 4, 2007 We are talking stock cylinder ported motors, yes! Not stock cylinder strokers. A stock cylinder motor standard bore or overbore with a stock sleeve is considered a 350 in my book. You put in a 4 mill stroker crank though, it becomes another animal. I think most people in here were thinking the same way, cause almost no one is on the stock standard bore. So now that we are done nit picking the details. I think a 64.5mm on a 4 mill is like a 376cc motor. Quote Link to comment Share on other sites More sharing options...
sredish Posted October 4, 2007 Report Share Posted October 4, 2007 since you already have the carbs, try them, it costs nothing. try them and if you like them, great, your set! if you don't, then you know. Quote Link to comment Share on other sites More sharing options...
