2 stroke or 4 stroke?

[crabdance]

There are may members here who have the kit you showed. I'm sure someone else can advise. The only thing bad I have to say about my GEBE set up is the fuel tank is too small. The tank in my photo, I only get 25 miles and it starts to sputter a little. I always carry extra fuel in a small camping white gas tank. They do make larger tanks but they are bulky or sit off to the side. many like them, but I dont like the look. (Personal preference) I do have to say I LOVE the engine though. I've heard of people with 5-10,000 miles on them.

Hope someone will chime in about the 4 stroke I provided a link for and let me know what they think about them. I've heard nothing but good things about the GEBE units (with the exception of one person on a wild rant). Everyone seems to be really pleased with them. Can't you use one of the frame mount gas tanks? Or is that not possible (sorry if that's a dumb question). I'm so new at this I don't know. 10,000 miles is awesome!!! That's killer. Can't help but love that.

..antoher thing about 4-stroke is that you dont smell exhaustion and 2-stroke oil from your clothes all day at work

That's a good one... never thought of that.

Rack mounting will allow for a wider variety of bicycle frames including full suspension and theres most likely more modification needed to fit a frame mounted engine onto a bike. I also found between my 2-stroke happytime frame mounted and my rack mounted staton mitsubishi 2-stroke there were a lot less vibrations (almost none). This is probably mostly due to the superior engineering of the Mitsubishi but I think the rack goes a long way to isolating the engine vibrations from the bicycle frame. I'm loving it so much I may just sell my Stingray to somebody who wants to get into motoredbiking in style. Keep in mind too that those frame mounted 4 strokes are fairly large so you would probably want to start looking around for large framed bikes to fit it.

Thanks for the information SrJakesus. I guess it makes sense that the rack mounting will fit a wider variety of bikes. At least you have more than one so that you can compare! You said that I need to get a large framed bike. Here is a link to one I was thinking about getting. Does anyone think this one would work?

Good luck if you decide to sell your Stingray. I don't know how you could part with it though (smile). I'm sure it's like a family member.

Thanks for the help and the info. Everyone is helping me out with my research and with each bit of information things become more clear about which way I need to go when it comes to selecting my bike kit.

thanks everyone.

The kit you provided the link to is the Grubee 4-stroke kit using the Chinese clone of the Honda GXH50 motor. I believe you will find that it is a good kit and most of the folks who have bought them are happy with them. That being said I think that you may run into some problems mounting it into the bike you provided the link to. The motor needs approx. an area of 10in.X10in.X10in. Also the size of the downtube of the bike shown is way oversized and I dont think the motor mount provided with the kit will fit it. As for starting the 4-strokes most of the engines available in the various kits use pull starters and centrifical clutchs, so no you don't bump start them.

Hi ocscully,
Thanks for the information. I've heard good things about the Honda clone so that makes me feel good. I don't understand about the bike part though. Are you saying that it's too big or too little? Sorry.... just don't know about these things .

I have this kit.

What he means is two things- the top tube seems to come down at an angle where it would interfere with the air cleaner for sure, possibly the carb itself. I did away with the air cleaner box and made my own, but that would not solve the problem is the carb itself would interfere.

The front down tube may be an issue as well. It is very thick. The mounting plate is a half circle that must fit around the tube. It fits mine perfectly, but the down tube on that bike is much thicker than mine.

Here is a pic of it of what my bike used to look like where you can kind of see the clearances.

Can you take a look at Walmart (or some other retailer) and find me an example of a bike that might fit the bill? Thanks for the extra info about the bike. I appreciate any help. Just trying to find something that works. Your bike looks great. Glad that you got it working good. Are you happy with the engine?

I'm saying that I think that the tub diameter is to fat. The Grubee kit comes with a mounting plate that is adjustable for length front to rear. The Adjustable ends have a U shaped opening in the center of them that goes around the seat tube at the rear and the downtube at the front. My best guess is that the largest tube dia. that this mount can handle is probably 35mm/1&3/8in. dia. The down tube on the bike you linked to is quite a bit fatter/larger than 35mm, I believe. If you are able to go to your local walmart and measure, it might save you some headaches later. You may also want to take along a piece of cardboard that measures 10in.X10in. to confirm that there is enough room in the front triangle for the motor as well.
