    A cub motor is designed for wide open high revs. Definitely not for just cruising around you should get a 421 serval, that would suit your ride style from what I can see.

    No matter what one i rode a 250r, Tecate, Lt250r, Quadzilla, Yfs200, Trailblazer, Trailboss Banshee and several bikes they all did them same things. Plain and simple it's a 2 stroke thing. It might be more pronounced with motor size and the type of porting but still well known cons of any 2 stroke. They don't have much torque so they don't lug well and are more of a workout to ride any tight terrain. I haven't seen many 2 smokers to start without blipping or cracked throttle either. These days no one buys one to not be in the PB or to lug and should expect it to start more finicky then the opposed 4 stroke. I bought my Banshee for the oh shit factor, mid to full throttle runs, the sound and the instant fear it strikes in most 4 Jokers minds. I most definitely didn't buy it to lug or ride on anything short n winding.

Real riders and builders will know what you're talking about. Also for you slow people he was lugging it on purpose to give an example. If you're to slow to see that you definitely don't need to be riding banshees or even in the market for one😂😂

    I have a 421 Cub Serval and it is built exactly to the same specs as yours same pipes same crank same everything except mine is a Serval I run smaller domes for pump gas but I start making power I think it was between 3600 and 3800 rpm the Serval starts making power and a Cub doesn't start making power till like 6800 rpm my builder even told me he says in a drag race a serval making 80 horsepower can easily beat a cub making 90 horsepower in a drag race just because you start making power sooner yes you might not make quite as much peak horsepower but if you're barely able to drive the thing in anything except asphalt then what's the use of it unless you're drag racing more straight line stuff

    • @banshee100
      @banshee100  2 ปีที่แล้ว

      Maybe if you're racing dynos in 5th gear I have races ported seals on racegas and still beat them ,under the curve a serval makes power faster yes but you don't race a cub in the wrong gear ,example serval 3600 50whp 8000 80whp my cub revs to 9700 98whp you may have alittle more down low buy the top whp will always come back around ,but yes a serval is better all around woods motor no doubt

    @MrATOMBOMB420 2 ปีที่แล้ว

    All these issues that you don't like would be fixed if you were to buy a Cub Serval that's why the servals were brought out the Cub motor is a drag race motor they are all top and people that buy them and try to build them for the trail it never will work you can't get that low end power band with a motor with extremely high exhaust port durations high transfers and high exhaust ports give you lots of power let's keep run lots of timing and lots of compression but they don't make power till the top end that's the drawback to them

    • @banshee100
