    I am considering purchasing the 36T sprocket. My bike has 26" wheels, and I weigh 275 lbs. Will the 70CC motor produce enough power to wind out the motor and go 40-45 mph with my weight? I don't want to run that gear if I cant get the max top speed out of it. I also am concerned about it bogging real bad when im going against a strong wind. I plan on cutting out the baffle in the muffler, and running the better flowing intake. I hear that helps alot.

    Josh, Mine bogs in the wind on a 44T sprocket and I am 257LBs and 26" wheels.
  3. you DO NOT want to go 45mph on one of these bikes !

    I have gone at least 40 mph peddling, I am not afraid to do the same with a motor :evil:

    I only have a single speed 26" cruiser, with my 36 T I could get 34 mph, I now have a 40T and can hit 32, acceleration is faster. I weigh 195 and cant get in the 40's, not that I want to. I have tried the boost bottle, cutting the baffle, upgrading to the bigger exhaust, changing the carb clip, changing carb and the only thing I seem to be able to do is get a smoother acceleration, the top end hasn't changed much

    Hmmmmm.... maybe I won't be able to use the 36T to my advantage :(. Oh well.

    Loose some weight man. You could be dead before you know it. Btw organic food and body cleanse's imo psyllium husk and candida will make you drop weight very very fast. Food filled with chemicals imo 99% of everything in a supermarket will make you fat. If you cant afford organic at least cleanse your body of toxins and gain muscle. This will in speed up your metabolism 10 fold.

    I normally weigh 230s. I'm 6' 3. I got fat after I lost my job. My biggest problem is I like to drink beer. That goes right to my gut.

    I haven't even tried the 44 yet. The first kit was a cheapo ebay kit from boygofast. His sprocket is advertised as 44, but i counted the teeth and there are 50. The top speed was 23 mph. At that speed it sounded like the engine was going to explode. I can't wait till I try the 44. My dax kit should be here in about 2 weeks
  11. LOL.

    I have a boygofast kit and weigh around 230... she sure does scream. :)

    The dax kit doesn't look to be any different tho - are you building a second bike or are you simply dissatisfied with the boygofast kit?

    I think the only way to reliably make the kind of power that I want is a NOS kit. I dunno if I have the cajones to pull the trigger tho.

    stud broke off in the motor. I tried getting it out with an easy out with no success. I ended up selling the motor to pay rent. I was unemployed at the time.

    port out the intake,make it oval shaped,aswell as the exhast,dont try to match it to the head you,ll go right through the side of the intake.im 260 my top speed is 51kph.40mph is asking to much from a 36 tooth.wind will reduce the top speed by around 3-4 mph depending.but mine accelerats quicker in the mid rpm band from 20kph up.i also added a boost bottel,but it didnt do that much cause of the porting but some.also you can shave the cylinder 30-50 thou for more compression,but the shop around here want,s $60.

    Eat drink and be merry

    There is nothing so much fun as happy times beer (home brew) and happy times motored bikes.But not at the same time.

    Eat drink and be merry.Lifes too short.:rolleyes:

    Don't eat that organic stuff. It will kill you. And we all know beer is good for you. Enjoy !!
    And keep the rubber side down.

    Pedalling is different

    When you are pedalling the clutch is in and the chain won't lock up when the engine seizes. Or, on a non-motored bike, you probably won't come to grief.
    Believe me if you have done thousands of miles on these motors the day comes when the engine seizes and you probably can't get the clutch in quick enough because the back wheel is locked and skidding outwards to the right and you are fighting to stay on it. It's all over in a couple of seconds.
    I have had this happen although only at 15 mph and I ended up on my face in the ditch with the hot engine burning the flesh off my legs. If it had happened on the freeway 2 minutes earlier I'd have been dead. If you want speed then get a freewheel hub of some sort so you live to tell the tale of the engine seizing. At 40mph a wheel lock up would throw you off in a split second. Cycling Australia states that hitting a labrador dog at 35mph is usually a fatal accident on a bicycle. Just a warning from a cautious old cyclist.
