Nice lookin Shee for sure, but I agree hp should be atleast 75 on a 4 mill. My midrange port stock stroke stock bore shee ran 65 on this dyno.

[400redrider]

Yeah I not sure exactly what was going on with it but the last trip to the dyno they got running real good (not sure on numbers though)

thats a nice bike, but im sorry to say that 60 hp and 32ft lbs of torque for a 4mill is pretty weak. that thing should have ATLEAST 75hp. somethin aint right.....what all is done to it besides the 4mill crank?

[400redrider]

Yeah he can't figure it out ether the guy that built his motor told that it should be making 80hp but after so many dyno runs I think he's going to build another 4 mill and try again. I don't know exactly what else has been done

[Laluush]

who is gonna biuld his motor now???

[400redrider]

I think he is going to build it his self. He has all the stuff to build another one

Thats my daddy's bike! Its doing well now, +6 swing arm, gasoline, and running about 80 HP.

@uae3276 110 or 115 rods will work on a 4 mil set up. It is the difference between a long rod and the short rod crank. However, your rods don't change on a 4 mil crank. It is the position your rod is located to the lobe that changes. You don't convert a stock crank to a 4 mil. You buy a new crank. I don't think you can fit a set of 68 mm sleeves in a set of stock cylinders.

@stevejakx14 Not very many people run fans. If you can't run this short of a time with little air movement then your jetting is way off. A correctly jetted and tuned banshee runs well with the stock cooling system in any climate.

@jwuzhear a 4 mill is a stroker crank that is 4 millimeters over the stock crank

the love the sand dunes there been there 6 times and have seen the dyno they have, there pretty cool

[uae3276]

hi, i am looking into building a 4 mil, my question is would 115mm rods fit on stock crank or do i have to buy a whole new crank? and will 68mm sleeves run in stock cylinders? thanks

[stevejakx14]

=o you runnin a fan assist on the banshee?

if i ran myn that long with no air movement she would have melted down.

ty in advance

[jwuzhear]

[airportbaggagex]

head, intake porting, exhaust port, pj34 carbs, either sheers or c.p.i, ricky stator, 4 mill, 65mill bore, je pistons. equals an 83hp 4mill
