devo Posted September 2, 2014 Report Posted September 2, 2014 I have a 421 serval shearers and 35mm pwks. Tuned 50 160. 70hp. Want to go back to stock carbs, how will it affect performance and HP? I'm thinking about 30 380. Quote
jriffe23 Posted September 2, 2014 Report Posted September 2, 2014 why stock carbs if you dont mind me asking. Quote
WINDYCITYJOHN400 Posted September 2, 2014 Report Posted September 2, 2014 Please don't say so you can run the stock airbox.... Quote
devo Posted September 2, 2014 Author Report Posted September 2, 2014 No room. Pods burning on pipes. Quote
sprinklerman Posted September 2, 2014 Report Posted September 2, 2014 No room. Pods burning on pipes.Run proper intake (upp) , proper angled k&n filter, and cascade heat wraps. Quote
trickedcarbine Posted September 3, 2014 Report Posted September 3, 2014 As bunk as shearers are, they are supposed to clear filters. At least mine do with 10-15 degree pods. Should be plenty of room. Quote
devo Posted September 3, 2014 Author Report Posted September 3, 2014 Yer like an idiot I got air box style. Have you guys had a problem with your thumb throttle being able to open the 35s all the way? I got a billet one atm and it don't have the leaverage to crank carbs all the way. Quote
devo Posted September 3, 2014 Author Report Posted September 3, 2014 Dynoed it last week and found slides only open 80 - 90% Quote
dirtydownunder Posted September 3, 2014 Report Posted September 3, 2014 27.5 or 30 pilots and 350 mains for stockers mine clear with angled pods with 34's. Quote
trickedcarbine Posted September 4, 2014 Report Posted September 4, 2014 (edited) Yer like an idiot I got air box style. Have you guys had a problem with your thumb throttle being able to open the 35s all the way? I got a billet one atm and it don't have the leaverage to crank carbs all the way. Dynoed it last week and found slides only open 80 - 90% Hmmm. Bought stuff that doesn't fit. Didn't realize bigger carbs need more cable pull till paying for dyno...... I'm like an idiot? By the way it's spelled you're in that context. A period would show non nigrosity or class.... Try grinding a little material back where the stop is for the throttle. Should fix ya up. May need taller adjusters as well. Edited September 4, 2014 by trickedcarbine Quote
devo Posted September 5, 2014 Author Report Posted September 5, 2014 No I meant myself for buying air box style when I knew I would run pods. Sorry if it sounded different, I'm Aussie.... Quote
trickedcarbine Posted September 5, 2014 Report Posted September 5, 2014 No worries, you're from a third rate CUNTry. Quote
RadarRacing Posted September 5, 2014 Report Posted September 5, 2014 Get the right filters. The 35s are a much better carb for it IMO. If you need to you should be able to get filters thru a kart racing company. They usually have KN style filters to fit that size carb and you can get the proper angled ones. Quote
