    Finally, a good seat.

    I don't know about you but a bicycle seat just doesn't get it when you're going down the street at 35 or 40 mph. I don't want my back side hanging out over the rear tire. I want to get down in and have better control. I looked every where for such a seat for my 29er and couldn't find anything...

    Reasons for riding Motorized Bicycle

    I don't know what the small cliff line meant but, as far as your comments go about growing up and wanting a moped go I really know what you mean. As a kid I always wanted one. We were the average family in Western Pa. in the 50's. We got along ok but no extra money. The poorest family in the...

    Reasons for riding Motorized Bicycle

    Come on now, I'm just trying to get a crude little motor to run as smooth as possible.The one in question will do about 48mph. Thanks to Arrow Motor Bikes ported cylinder. rechambered head and expansion chamber. The Delorta SHA 15/15 didn't add any speed but it does run a lot smoother at top...

    Best overall 66 cc carb?

    I really like it. Once you get it jetted right, 66 or 68, even a 65 in some cases, and get rid of the very restrictive air fillter, it gives a smoother and faster acceloration because of the flat slide instead of the barrel. I don't know why they install that filter knowing full well that the...

    what did you do to your motorized bicycle today?

    So I put together a speed version of the China Girl for a guy that paid me $1.600 for the bike and motor. Grubee 66cc, expansion chamber, Delorta SHA carb, Arrow Cycles high compression head from billit alum. with extra big fins for better cooling, ported cylinder and polished piston. I was...

    what did you do to your motorized bicycle today?

    Today I removed the Delorta SHA clone carb. and re-installed the NTS. I grinded off some of the inside of the drive gear cover so that the 415 chain will stop tearing it up. I discovered that my sprockets are out of line.In other words, I just tinkered with it, the way I always do and I couldn't...

    Clutch Doesn't Work Grubee SkyHawk GT5

    You are absolutely correct about that. Even the 410 chain will tear up the gear cover if the tension isn't just right. I line up the chain just to the left side of center and that usually eliminates tearing up the inside of the cover. My big problem with this build is to get it to run witout...

    Reasons for riding Motorized Bicycle

    I live in California where the China girl isn't legal. I still ride mine through the neighorborhood streets and once in in while to run an errand. My biggist joy comes from building them and trying out new parts like carbs, rechambered heads, pistons, exhausts, brakes etc. It's a great hobby...

    Clutch Doesn't Work Grubee SkyHawk GT5

    Yes it is. You are correct but bucking at 15 to 20 mph is not normal. I build these bikes to sell them. I can't put a new rider on a bike that won't go slower than 20 mph or so. All of the others that I have built will run fairly smooth down to about 10 mph. I was really hoping that some one out...

    Clutch Doesn't Work Grubee SkyHawk GT5

    Gearnut Thanks for the comments. This is the 9th one that I have built and it's the first one that I can't get right. Made some modifications that did cost some money and I just wanted to know what else that I could do to get it to not buck under 15mph or so. That's all. If there is nothing, so...

    Clutch Doesn't Work Grubee SkyHawk GT5

    Ok you're right. My question was more about the way it ran as stock and the way it runs now with the modifications, ported cylinder, rechambered head, expansion chamber and SHA carb. The bike idles at about 25mph and runs very smooth with a lot less vibration. I just wanted to find out what, if...

    Clutch Doesn't Work Grubee SkyHawk GT5

    Sky Hawk GT5 ran really good at all speeds. Installed a ported cylinder, high compression head, expansion chamber and Delorta SHA clone that I rejetted to run well at top end. Now the motor bucks when I go under 10 mph. Does anyone know what's wrong?

    Clutch Doesn't Work Grubee SkyHawk GT5

    These motors are pretty simple. All you need is gas and spark. Check to see if the gas valve is open. Check to see if the kill switch is not on. Check to see if your CDI wires are connected. In cold weather, make sure you choke it to start and lastly check your spark plug connections. If you do...

    Best overall 66 cc carb?

    I have used NT, NT speed, CNS and Delorta 15/15 on a 66 cc with ported Arrow cylinder and high compression head with an arrow pipe w/ expansion chamber. I threw the CNS away after spending a lot of time oin it, never could get it right. The Delorta needed re-jetting out of the box to a 66mm, the...
