Abe Posted June 7, 2012 Report Share Posted June 7, 2012 . My bike has stock stroke, t5 pipes, really good clean up port job on 65mm cylinders, and pro flow setup in air box with vented lid. I already have a set of 35mm pwk carbs and would like to use them but have a feeling they are way too big. What do you guys think and any suggestions Quote Link to comment Share on other sites More sharing options...
special06shee Posted June 7, 2012 Report Share Posted June 7, 2012 Might loss a bit of bottom end but id say try them out!! You'll pick up a bit on upper part of mid and top end if ya run pods!! Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted June 7, 2012 Report Share Posted June 7, 2012 Way too much Carb, but like ^^^ said, you'll lose bottom-end but might gain a little mid and top. Stock carbs w/K&N's, 91 pump, +4* timing, T5's and a HJR Dune Port have been dyno'd just a touch over 65whp. http://www.herrjugsracing.com/files/Alec1.bmp Plus you will also need larger intake manifolds to run the 35mm PWK's.

ban565 Posted June 8, 2012 Report Share Posted June 8, 2012 28 pwks would be a good for your mods. Quote Link to comment Share on other sites More sharing options...

Abe Posted June 8, 2012 Author Report Share Posted June 8, 2012 thanks for the info guys looks like the 35s are up for trade to a nice set of 28mm Quote Link to comment Share on other sites More sharing options...
special06shee Posted June 8, 2012 Report Share Posted June 8, 2012 thanks for the info guys looks like the 35s are up for trade to a nice set of 28mm keep the 35's and try them!! with your motor combo your not gonna feel a huge difference with any carb!! you will end up doing work to the banshee down the road and will need the bigger carbs!! trust me!! try them out!! they will work just fine!! if you feel that you lost to much bottom(witch i personally dont think it will hurt it that much)run the factory carbs untill you go bigger on the motor!!

lms1977 Posted June 8, 2012 Report Share Posted June 8, 2012 I would also say try try them.. If you get them jetted right they should work fine. Quote Link to comment Share on other sites More sharing options...
Abe Posted June 8, 2012 Author Report Share Posted June 8, 2012 i dont have a set of stock carbs so to save myself money down the road guess ill just try and buy a cheap set of stockers and try them both out. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted June 8, 2012 Report Share Posted June 8, 2012 If you do choose to run the 35 PWK's, you better get yourself versed on tuning. Get a carb sync tool from FAST and a cheap ebay tachometer. Open up those 35's and find out what jets and needles you have in there already. Do you have an intake manifold to run the 35's?

Abe Posted June 8, 2012 Author Report Share Posted June 8, 2012 yea i have pro design intakes but im gonna have to get sum new boots due to the old ones being cracked, also the carbs have factory jets and needles now, DEK needle-160 main-48 pilot i believe is the setup. have any suggestions for starting jet sizes Quote Link to comment Share on other sites More sharing options...

He will get you real close on the jet sizes!! Ypu'll just have to fine tune from there! The pwk35's are very easy to tune!! Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted June 8, 2012 Report Share Posted June 8, 2012 Most people run CEL needles. The 48 pilots sound good. The 160 mains might be too big. I would think 150's, but see what Jeff says. FAST might even have the boots you need for your intakes too. Remember, jetting is affected by humidity and air temp which when jetted correctly should be tunable by the air screw. Elevation changes of 2000ft or more will always be the biggest factor in jetting. Get the Sync Tool too! Quote Link to comment Share on other sites More sharing options...
