    I put my 66cc ht engine on a better bike this week. The bike is a roadmaster. Before i put it on though i opened up the exhaust port on the jug and the header and now it has a ton of power. I was riding yesterday with my friend and i got up to 32mph on the flat and 23-24 up the hills. That is good compared to me top speed of 17 on the old bike. now I will realy anoy the neighbors.:devilish:

    Don't annoy your neighbors.. remember the old saying "Don't sh--t where you eat"

    exactly! I do the same think just with motorcycles and nitro rc airplanes and they have learned to just ignore it.

    lol...i have a 66 triumph bonneville with straightpipes, my 55 pontiac has dual straightpipes with no mufflers,my occ chopper bike has a modified muffler that is kind of loud, my stingray has an expansion chamber with a modified muffler, i run nitro r/c cars with tuned pipes, so i make plenty of noise.
    Thankfully, the majority of my neighbors are gear heads, and they love it.
    my neighbor down the street has a top fuel funny car in his garage, and no one in the neighborhood has anything louder than that.

    my speedometer said you were going 27 on the flat, if i remember correctly.


    and also, when i rode your old bike home for you, i was doing 25 according to the speedometer in my mothers ford explorer (and thats with the crappy old Kent bike).
