    Hi guys. Little back history. I have a roadmaster mount fury 24 inch frame with a black 80cc china girl. The engine clears so far but i have some issues that i wabt to touch base with. The lower tube were the mount is, is rather large and the bolt holes dont match up. I could squeeze the frame a lil bit to fix it i believe. The next thing is the carb dosent quite fit and i dont want to lean the engine to the side in risk of the chain binding or being off center. Anyone have some direction on were to go with this? The bike was free and a few buck to make it work is better then trying to find a decent 2nd hand bike. I can get lictures later today. Thanks. Mike.

    Just get an offset intake manifold to put the carb off to the side of the seat post.

    No reference for where to get one, sorry, but that will do the trick.

    I just saw those. Some on ebay. I did buy some brass fittings its just that that were the exact size as the intake and it wouldnt slide over the pipe. Thank ypu though. Your bike looks great btw!

    Nice.
    I don't have the time make my own intakes nor do I need to, I have draw full of them ;-}

    40 mph is great for a direct drive, how is it off the line?

    Looks like a smallish 36 on the back so off the line will be a slow one lol...

    Kinda hard to see what you have there. Would you like to share your enhanced intake design with us?

    Ya, pedal your ass off to ~20mph and then you get the speed.

    Nothing more relieving than having the motor take over just as you're about to faint, good ol motorized bike spirit.

    That's not really true most of the new stock Zeda's come with a 36t gear and can turn them fine on a 26" wheel,I use two different ratios one for the street and one for the track and granted my engine is modded to use those ratios being 2.36 for the street and 2.72 for the track I still only peddal a couple times of the line on the street just to help it get up in r's quicker and save my clutch at the track I dont peddal it's all on the clutch and still pulls out of the hole just fine!If you can make the pipe stage properly at a lower rpm it helps to overcome the higher load from smaller gearing and allows the engine to get up to peak rpm where it makes more power on it's own.

    This is with my lowest numericly ratio and it pulls from a stop with just a couple peddal rotations and starts to unload allmost right away,My cam has a noise supression feature that makes it hard to really hear the pipe still you can plainly see it's not labouring to turn the lower ratio.
     
  14. Switch ur speedo from kms to mph lol

    I live in Canada and the speed limits are in kph as you can see on the road signs!
     
  16. The closer to the cylinder you get with the carb the better it'll run. Just like a chainsaw I run a 44t sprocket port an polished the intake&exhaust and shortened the intake to deliver the fuel faster to the cylinder with 32:1 fuel mix and a #68 jet in the carb 3 yrs and still runnin strong and the only time I use the peddles is to start an stop good take offs and great top end.
     
  17. So ur goin 34.7 mph then the pic was sorta making people think u were doing 55.9 mph just sayin lol

    Yes at 1/4 throttle it still has a high 60's in mph top end!If you watch the speedo screen it cycles thru the odometer,average speed,max speed and so on and at that point my max speed was 91.4 kph just over 55mph.The fastest speed on that bike so far has been 72 mph.
     
  19. Theres a better pic, you look inside all the stock intakes and you'll see burs from cuttin and weldind sorta hard to debur inside so I shorten the whole intake straight shot into the cylinder real easy to do either weld or braze either works I myself braze for I don't have a welder anymore.
