    Hi, I am new to the whole motorbicycle world... I stay near Ruston, La... Which is northern Louisiana.. I also attend Louisiana Tech University..

    I have a few questions....

    1. What would be considered as a good donor bike... and particular traits..
    2. What is the best motor kit to buy? I already all about morini, but i dont have the money for it. I want to spend less than 150$ shipped.
    3. I have read alot of threads of people modding their engines, what is the best way to get more power?
    4. What do you recommend as a great 2 stroke oil, and does premium gas help with horsepower?
    5. What is the best tooth combination for mild hills and 35-38mph top speed?
    6. Any other tips to help a new rider out? anything and everything....
    And i dont have the money for a shift kit..
    Thanks in advance!

    My advice is to listen to Bikeguy Joe. Power will increase a lot during the breakin process. In general, the first, most cost efficient performance mod for any two stroke motor is an expansion chamber, or tuned exhaust.

    I don't think 35-38 top speed is going to happen with a 40T sprocket. I have a 36T, a tuned pipe and a broken in motor and I top out at 30 which is plenty fast enough.

    One thing I'm going to have to disagree on with Joe is the best oil is Opti-2. :p

    I have no intentions of starting an argument here but I have a 41T sprocket, a 66cc Straight plug 6mm head stud engine and it's on a mountain bike, it will run 34-36 easy if you can take the massive vibration form those RPM's it will do 38mph if i'm on a slight decline, but 30-32mph is an easy speed for mine with mild vibration or I can back it down to 25-27mph with almost NO felt vibration at all.

    these speeds have been confirmed by multiple vehicles and not just the digital speedometer on the bike, I will say that for a comfortable speed I would suggest the 40-41T for someone who is happy with the 25-30mph cruising speed it works the best for me at that speed range, but will run 35-36mph all out if you need it too, once the engine is broke in good and if it is tuned right, I dont have a tuned exhaust or a fancy carb. on mine either, I have a stock NT carb. and an exhaust I made out of 3/4 flex pipe and it has a small lawn mower muffler brazed to the end of it which I enlarged the holes in for better flow, flex pipe leakes and stays a little oily but works great for me.

    The 41T is my favorite over all I have tried for all around power and mocerate speed. cant go wrong with this one in my book. I put a 36T on my other bike which has the slant head engine and it is slower with the 36T than my other bike is with the 41T.

    Now that i have had my bike for a while i do have to agree with Kevlarr.. Opti-2 is the best!! It makes it run so much better.. I have done a good bit to my bike since i got it, but at no time was its top speed 30mph.. It did go down recently from a good porting job (already did port matching, this is real porting) so a friend ordered new jets for our bikes.

    I would like to thank all of you for the advice and if u are ever in Ruston gimme a shout and we shall ride!

    I only top out at 23 mph.. 49cc, stock parts, 32:1 running formula 1 premium motorcycle oil. I have 24" wheels and a 44T sprocket. Anyone know any ways I can increase my speed?

    I can't, the frame is too small. I really wish I could use 26 inch wheels, because I don't want to waste money on 24 inch wheels when I could just buy a new, cheap bike with 26 in wheels.. I am wondering if it would just be cheaper for me to buy a new bike and put my motor on that

    ....or go down a few teeth on your rear sprocket, say from 44 to 40 or 36.

    I have also come to decide that I like the idea of my first MB build being on 24 inch wheels. That way when I build another I will have one with 24 inch and one with 26. :D

    I think I am going to try 40, I am lucky to live a 5 minute ride away from the zoombicycles warehouse, so I buy all my parts there. They are going to have expansion chambers for sale in 3 weeks!
