Could someone tell me if this motor has been discontinued?

If so,anyone want to sell one in usable shape? I will be getting parts from agk so at least running condition.

It was replaced with the 99cc Predator, why not just get the Pred instead? 20cc more displacment won't hurt powerwise ;)

Mainly trying to stay legal. I'm in oklahoma and the law is 125cc now but its being changed to 80cc I think.

Or some people are trying to get it changed would be more precise.

All I can say is "good luck" then on your quest for a Greyhound 79cc. They are still around here and there so don't give up. If you have HF nearby, check with them frequently for one that may have been returned for whatever reason.....ya never know.

Its actually 150cc (WOW!) with a design speed of no more than 30mph (WTF?) regardless of cylinders.

And thanks. I can already tell its going to be all uphill on this search.

No prob, just go the 99cc and search over ;)
 
I have a new HF79, motor mount, and complete AGK gearbox with clutch and gearbox cover I've been thinking about selling.

Needs an exhaust, throttle mount, and rear sprocket setup to complete it. $300 shipped
 
Damn aleman,that's exactly what I was looking for. I was going ro buy it piece by piece......I'll be in contact
 
Hey aleman,I have this bright idea and need you to school me on chain size,pitch,etc. one more time.

If I have a #35 sprocket could I use #41 or #415.

I think you may have told me before but.....

No, you need to use #35 chain with #35 sprockets.
 
If someone else is also looking for a 79cc Greyhound. I have one I never used on a project. Put oil in it and started it up once just to see that all was well. Don't have the box anymore, but the motor is just as it was coming out of the box. P.M. me with an offer if you're looking for one.

The gearbox itself uses #35 chain, but the output drive sprocket is #41. The output sprocket can be easily changed to #35.

The gearbox itself could be changed to #41, but you'd need a new clutch and input sprocket.
 
Is there any chance that if you built it now, and it is currently legal, that it could be "grandfatheted" in" if the laws change? Like older cars and motortcycles that don't have turn siginals or seatbelts, smog control ect are still legal.
 
The #35 chain and sprocket are for another project with my 4G tranny. After the one way went out,I j.b. Welded it and now I miss the freewheel. So I am trying to change it to a chain drive. Is there a sprocket that will work with #35 chain other than a #35 sprocket?

Sprockets for 35 chain are available in a huge range of sizes from go kart suppliers for reasonable prices.
What size sprockets are you looking for?
 
I need a 36 tooth that can be drilled to fit on a freewheel from sbp,staton Inc.,that's dax,etc. I think the inner diameter is 1 3/4"
 
I've been looking for a formula or a calculator to determine outer diameter of a #35 sprocket. Anybody know what I'm talking about here?
 
Open the DIY forum and there's a calculator in the first thread. Don't know about how to determine diameter If you know the teeth count that you need, call a supplier and ask them to give you the diameter.
 
T / Pi * pitch = D

Example: I have a 75T #35 sprocket. 75 divided by 3.14 times 0.375 = 8.957 inches.

Example 2: I have a 51T #41 sprocket. 51 / 3.14 * 0.5 = 8.12 inches

Thanks Wayne. I did think to look here. I'm a fool most of the time. The rest I blame on my wife and kids.
