Did you say a 19 front sprocket?????? and a 36-37 rear??? Thats enough gearing to do 130. I don't think that is accurate

rd= real deal

For asphault yes. I run a +4 and have no issues keeping the front end down

Try tightening the oil filter, you can lose alot of compression through there....

Lets just posts the fastest radar runs with each set of carbs. I have a 4mill stroker/stock cyl, on stock carbs running nice, I swapped out to 35 PWK's and didnt gain a .1mph. Stayed at exactly the same mph. I then tried a set of 39's and guess what same shiet. The only difference is that with the big carbs I can only run for 1/3 of the time due to gas consumption. All tests were done in a 1/4 mile

Are you building a 4mm stroke with a 68mm bore cub?

Why thank you kind man.

Where would one purchase a set of wheels like this?

Well when I went to buy tires they only had 22's (stock's are 21's)for the front but I do have 20's in the back. I also swapped my gearing to a 17/40 and got the same exact results. It doesnt lose or gain anything. The only way its gains mph is by putting a light rider on it (150lb). It picks up almost 2 miles. 107(1/4 mile)/112(top end)and this is back on stock carbs. I put the 35's to the side for now

I am running c-12 with 6 degrees advanced timing, and I have my air lid on (for some reason it pulls better like that). My jetting on the stock carbs are stock pilots and 330 mains

Any more advice... Anything

Boost Bottle??

I have a 4mill stock cyl 66mm, no overide, CPI, DF3's, 17cc domes 190 compression banshee that did 105 in the 1/4 with stock carbs and 110 shortly after the 1/4. I threw in a set of 35mm PWK and didnt see much improvement but did see my gas tank go to empty 10 times faster. I guess what I am asking is, are the big carbs really worth it???? I jetted the balls out of them and got them to be perfect (no bog, straight pull through each gear). I ended up with 45pilot 152main. I am running airbox with adapters. Gearing is 16/38. Any advice will be appreciated

Yes. It ran 104.5 in the 1/4 and 110 top end (shortly after the 1/4). Here is a 1/4 mile pass on stock carbs (airbox on), no overide, no straps, no lockout and 16/38 gearing The issue is, I didnt see much of a diff by adding the 35mm pwk's

Never used to run out of gas. Stock carbs used to hold enough fuel.

Congrats. You now have the worlds most hideous banshee. Looks beyond terrible to me, but hey is you like it, thats all that matters

Just port it with a drill bit and a rock. These guys are nuts.... Just drill holes everywhere and 1 hole right through the top of the piston <-- secret blow hole. They try to make it sound complicated so you an spend money with them

Compression test time.

I usually run C-12 but my buddy said E85 has enough octane (105)... Can you even run that on a banshee??

wow, that is sweet

see my post above

Yea Tony thats top end which is maybe 20 feet after the 1/4 mile. Tony, you saw the video of the 1/4 mile pass at 104 and no its not being raped like the other guy said. Bike has stock tires. So if the OP sets it up right for top end he should get 110 in the 1/4 Heres a pic of the bike Here is a pic of my stalker on the 110 run Video of 1/4 pass

I have a stock cyl, 4mill crank with stock carbs that does 110mph on 16/38 gearing. So you should be atleast over 110

ho ho ho homo
