KEVSWS6

Only good on aggressive dune or drag ports. For people that are serious about getting all they can from the motor. For racing type applications.

The rod and big end YIKES! Time for a 4 mil. crank.

Try the stock carbs first they are paid for. They really do lay down nice numbers.

Sorry we didn't get closer on the jetting. The CEL is a good needle for the 35's and the port job.

You just melted the piston right? The rod and small end are alright? Have some pictures?

John at Sandtoyz is a great guy. Flotek is another that does good work. I'm partial to Kevin Herr myself :biggrin:

9 or 10 would be good in that size tire.

Low dollar operation here. I'm not dropping a 100 grand to pull stuff out to the desert. RV has been in the family since 1980. I went camping in it as a kid. You've seen what I commute to work on HA HA!

Look what I might be picking up soon. I will see if I can get it for the right price.

You guys kill me, thanks for the info. I have a dual pingle and 41's with huge billet bowls. I have the pump but was wondering if it was needed. Time to go run them!

Are any of you guys needing fuel pumps for your small 421 alky burning Cubs? Drag port around 110 to 115 HP motors.

OMG! :laugh: :beer:

What kind of port durations are you running on the 4mil? Do you have the blue prints on the pipe? What kind of dome configuration are you running? I'm not an expert but I can get 80hp on gas 4 mils. PM me if you want to take it off line or even care to talk about it.

I like all the motorcycle pictures you have. I want a 350 or 500 Yamaha 2 stroke street bike. Haven't found one yet. I wonder what kind of numbers I could get out of it. Looks like they are limited on expansion chamber size for the pipes. I never had much luck getting big numbers out of big bore sleeves. I do better with stock sleeves or after market mono type blocks like cubs.

Low Buck you get that motor assembled yet? Sorry had no time to talk yesterday. HQ motor will be together in a couple weeks.

Whoever buys these can ship them to me and I will clean and match both jugs so you will never tell that it had been chipped. This will not effect performance and I will do the work for free. You just pay shipping. These jugs will run hard with Shearers or CPI's

Right here: http://www.bansheehq.com/index.php?option=...2&Itemid=28 I still think swapping yours in will be the best way to trouble shoot it.

Butch did you figure this out yet?

Good deal!

How about the slides? Ever have the carbs off? The slides cutaway towards the air filter side. If you do not see the cutaway when you hold the throttle half open then the slides are in backwards.

With 21cc domes +4 timing on pump prem. will work for you.

Cant go wrong with a NOSS head. 20cc might be a little too much on a stock motor on pump gas. What elevation are you at?

Will someone come get my bike and run it for me. I have no time but the bike wants to go without me!

Its going to be hard getting a beater for that price. That money is in breakdown territory. Plan on wrenching or buy a little motorcycle. They get great gas mileage. Does not have to be as gay as mine but at over 100 MPG, yes I said 100 MPG I will be laughing at you too. Plus it will do 65 MPH all day long. Had it since 1980. Its a 1974 Honda Trail 90 with a Lifan 140cc motor in it.
