    Why do you want to go faster than 45mph? That's already too fast for a motorised bicycle.

    Why 'other than an expansion chamber' ? Why don't you want to fit one? That would give you a bigger boost than anything else.
    I see that you're still using a stock carb, too.
    What head work have you done? You could consider a decent high-compression head.
    Even a good quality, high flow air filter would help.

    There's lots that you can do to get more power. I just don't agree with buzzing around on public roads at 45mph+. That sends the wrong message.

    i just orderd an expansion pipe from spooky too and the cns racing carb with the ported intake manifold pre drilled for a boost bottle along with the bottle and i was thinking about having the head shaved to reduce the compresion room in the head but ill wait to see what the upgrades do first

    The pipe will make a huge difference. (I think that the SBP pipe is a little better, though.)
    The carb will also if tuned well.
    The benefits of boost bottles are debatable - some say they work while others say that they don't.

    A shaved head will help, but not as much as a custom high-comp one. Got mine from Rock Solid Engines here in OZ. Like you, I'm also running a shift-kit.

    Buy a motorcycle/motorcooter that was developed & made for such speeds would be your best option.

    Many people here do not like fast motorized bikes...it is touchy LOL!

    Expansion pipe made a great impact on my bike, and it is tuneable for low or top end. Boost bottle is only menat to help the acceleration of the line really. No help at WOT running. I did not look and see if you have one, but slant head and air cleaner are good mods too. Check and see if you have one or two head gaskets, SBP also sells a thinner gasket to boost compression. Check the exhaust gasket and port it to your exhaust flange, and can also open the ports with a dremel :)

    That is about my list!

    Just think, the attention you will draw to yourself by riding at 45 mph. If everyone who had a motorized bike rode at such speeds, how soon do you think these rigs would be outlawed ???
    SLOW DOWN & smell the " Sunshine."

    also, sometimes going fast is a plus. being able to keep up with traffic and not being passed is nice when you're on the side of a road with a 35+mph speed limit. especially when the side of the road is about less than 3' wide.

    the best thing to do is to get something cheap. like something from craigslist. Jap bikes from the 70's-80's make the best ones. get something around 350-650cc's and fix it up so it runs nice and don't spend too much on the look of the bike because after you get used to riding on the road you can chop it up and make a bobber, cafe racer or leave it stock. building a bike from the ground up is a little impractical for a first bike (trust me, after working on something for some time you get tired of it and just want to ride.)
    where are you located? I would be more than happy to help you look.

    Nitropeewee, that's 52mph, not kph? That's more than fast enough. Bicycles aren't built for those stresses. Things will break, and also the cops will take a dim view of an MB doing 60mph, as the OP wants to do.

    You know, I've had enough of stupid attitudes on this site, especially the last couple of days. This is the proverbial 'straw that broke the camel's back', as minor as it seems. I'll leave you all to your own devices from now on.

    Didnt mean to run anybody off :eek:o2ps:! Where i live (Ohio) our motored bikes are considered motorcycles, have to be registerd, insured and you have to have a drivers license. So making the police take notice isnt an issue. Again i am sorry i wasnt trying to make anyone mad, we all have a lot to give here dont let a bad day ruin it for you.

    Dunno what happened - I posted a reply but it's disappeared.
    Anyway, forget it. I was a bit frustrated.
    Your Ohio rules don't apply to most of us, and do you really believe that this is good advice for an under-16 year old:- "AWWW give em a break hes not even 16. Ive got mine up to 52 n still want more! If ya wana poke, then poke. Ya wana scream then pin it n scream!! Were all just havein fun right?"
    If nothing else, it will get our bikes banned in no time.
