First run on my 2 into 1


Recommended Posts

Well last weekend i finally started up my bike. Had a little dyslexic episode hooking up my ignition. Anyway my shee fired up first kick after straightening everything out. My fresh motor and reeds and homemade 2 into 1 intake. Well after taking it around the block a few time just trying to get it up to operating temp i checked out my intake and it was cool to the touch. Does anyone elses intakes feel cool to the touch while the bike is at operating temp? I am still expirementing with the length and diameter of the intake runners to see what runs best. For 10 bucks worth of aluminum and a day of my time i am not to concerned with making a few to test to see what works best for me. Dustin

that sure looks purdy.

 

i dont know about intake length concerning banshees in detail but i can tell you that on 2 stroke shifter karts it seems like everyone runs the intake as short as possible. actually ive seen alot of guys mount the carb directly to the reed cage and eliminate the intake entirely.

 

 

also it seems like alot of 2 stroke shifter carts run a 6-8 inch intake manifold between the carb and the air filter. i guess they get something out of it. ive seen quite a few banshees with long runners between the filters and the carbs. looks like they also use 6-8 inches. maybe you should play around with that?

It seems to me more length than the trinity would work better for keeping the charge going in and atomizing the fuel better.

only real way to "test" is on a dyno. make several different ones with several different lengths and put it on a dyno for testing, then you'll KNOW for sure what works best. It does look like a Graydon which is my favorite 2 into 1 setup. Also, don't forget to weld a crossover tube into that intake. Just use small, thin gauge alum. and bring it straight across, but you need to get some sort of equalization in there or you could have some slight running problems. cool to the touch is normal, it's flowing a lot of air and it will get cold and often times get condensation on the outside, very cool.

Ah thanks for the input guys. I am not really to concerned with HP numbers so i dont think i will be getting that intense on the intake. Just mainly using the old ass dyno. What feels to run better in my conditions. Oh i have a bored 36mm carb on there. Its bored to a 38mm. Thanks guys.
