reeds?
- Thread starter blasterKILLER
- Start date
They open when the atmospheric pressure is greater than that of the crankcase, then when the piston comes down it compresses the air/fuel in the crankcase creating a higher pressure and making the reeds close. when the piston uncovers the transfer ports, the pressurized air/fuel shoots into the combustion chamber.
running rich has to do with jetting. the only way reeds would make it run rich would be if you downgraded, like from v-force to stock or something. v-force reeds have better flex and more reed tip area resulting in greater flow than the stock reeds. so if you were jetted properly for v-force, then went to stock reeds the airflow would decrease but the carb is still givin it the same fuel, therefore making it rich.
go to howstuffworks.com and look up 2 stroke if you don't know how they work. explains a lot for the noobs.

He explained how they work, but according to the little pamphlet that came with my boyesen, they make it run a tiny bit rich on the pilot and lean on the main....or vice versa??? Don't quote me!!
boyesen reeds have a tendency to make a bike run richer...i agree with everything above except "running rich has to do with jetting. the only way reeds would make it run rich would be if you downgraded"
thats not an acurate statement. and xima i believe your correct..or vise versa !! ..lol
The whole cycle can be explained as follows:
1) As the piston moves from bottom dead center to top dead center it creates a
vacuum to draw the fuel / air mixture through the carburetor and past the reed valve assembly.
2) The piston moves down from top dead center to bottom dead center. The reed closes, causing the pressure to build in the cylinder. The movement of the piston uncovers the intake port and pressurized the fuel / air mixture.
3) The piston now moves up from bottom dead center to top dead center, effectively ending a cycle and starting another. The spark plug ignites the compressed mixture, sending piston back down.
4) At this point the piston uncovers the exhaust port, allowing the spent gasses to escape. As it continues to bottom dead center, it uncovers the intake port and allows the fuel / air mixture through the carburetor and past the reed valve assembly.
A highly tuned two-stroke engine produces a tremendous amount of power per cubic centimeter, and is still effectively raced against larger capacity machines in dirt racing, where lightweight is valued more than raw horsepower. Unfortunately, two-strokes do emit more pollutants than four-strokes, are louder, and tend to use more gasoline. It is unlikely the design can be sufficiently altered to meet current emission control standards, so fewer and fewer two-strokes will be made in the future.
and thats the only damn reason that two strokes are becomming absolete..it reallk SUCKS
before i bought my yz i had a 450f and hated it, traded it back in for the two stroke

just go buy the v force 3,best money you will ever spend, the throttle response change between stock cage and reeds and the vf3 is tremendous. oh and the 34mm carb is f*ckin sweet!
thats a nasty blaster you got man!, i just ordered plus 3 for mine, can't wait!I:I
+3 swinger?...if so, youll love it...blasters when stock are too much of a wheelie machine IMHO...the extended swinger really helps put the power to the ground !! it'll feel like a new quad to ya, and stand allot better looking also
you guys know if i could put boyeson reeds with a stock carb and stock pipes.will i have to get a bigger main jet or just tweak with the fuel and air mixture.
more than likely you can try to get away with doing the air/fuel but you might have to rejet. try it with the air/fuel and see what happens, if not rejet.remember stock is 230, 35 pilot
