Can you use Shearer pipes and Toomey T5 silencers? Is it bolt-on? Is it the same cascade clamp? Do I have to go down in jet

What does a pro mod transmission consist of? I thought pro mod and over ride couldn't let you compress...

Ok I guess every reputed builder knows this. Will do on my next order. What about my jetting?

Do you have the K&N part number? Last time I checked I couldn't find the right one with the angled boot to clear out Shearer's stingers

That's what I'm talking about! Thanks man.

Hi guys. The banshee was running pretty well but just wanted to have it perfectly jetted. Here's the info: 1) What type of aftermarket exhaust do you have? Shearer small bore inframes 2) What type of airfilter do you have? K&N pods replicas with outerwear 3) Are you a)running a stock airbox with lid stock airbox with NO lid c) Stock airbox with vents d) no airbox at all: No airbox 4) What is your elevation? Ground sea level 5) What size pilot jets are you using? 58 6) What size main jets are you using? 160 7) What temperature is your Banshee jetted for? I assume for fall temp 8) Do you have a port job? "Drag Ported" 9) What kind of carbs? Keihin PWK and V-Force 4 reeds 10) What size carbs? 35MM

Ok ok hold on all of you duners and drag people. I understand it's a bit overkill for the stock transmission a ported 421 cub BUT could it still work? I have the wrong motor for sure but I really want to shift it with the clutch just like a standard banshee. So I really want to avoid modded transmissions. Would with a Driveline performance dune/trail kit + straight cut drive gear + billet basket + lockup be ok for trail purpose? My transmission is top notch (for now ) and I have a modded shift star. I did not noticed any misshifts or any trouble shifting at high rpm. The point of this thread as mentionned in the beginning, could it still work even if it wasn't meant to be used in 85hp+ bikes? I don't drop the clutch at high rpm in dirt nor on asphalt. So imo the only way I can ruin it is clutchless shifting or repetitive drag racing. Has anybody here with a 421 serval or 421 cub with at least 80hp ever used stock unmodded transmission to cruise and still go fast with their bike? Thanks

No need big carbs unless you have a cheetah cub or serval 421 or bigger. As suggested, a pair of 28 PWKs would be perfect. Single carb is meant for single cylinder!

I think I will be going +2 as suggested by trickedcarbine. Trail riding is the main purpose of the bike but a longer swing arm will definitely help for drags and hill climb. Thanks. I was thinking about F.A.S.T. custom made swing arms. Any other known good round house swing arm maker?

I see. As you said earlier, stock lenght is good but will a +2 be bad? The reason I thought getting longer was to be able to drag or to hill climb someday without flipping the bike. So after all, stock would be the better option?

Do you guys believe in OEM's swing arm strenght for a 421 cub?

For real? Damn allright...

I only ride trails with my 421 cub. I weight 150 pounds. Should I get a +2 or a +4? I like corners.

Bruuuuh

Here is the result of the pilot jet change to 58, middle position. https://www.youtube.com/watch?v=BnZejCCoOMo I think it's just perfect. Obviously weather is cold and might have to change them for summer. What you guys think? Main jet is 160. 35 PWKs
