so AGAIN the jackshaft kit is the only thing that AGK sells that is made for the hf 99cc pred motor

AGK raced a 79 cc HF motor with a 2 speed gearbox at the last
Grange race. The bike was faster than the 5 HP Briggs bikes.

Affordable Go Karts will be at next April 7th Grange race with a
99 cc HF Predator with the same 2 speed so it will be very
interesting to see how it performs.

AGK is still testing the 2 speed but said that it would be for sale soon.

Neil

does that 2speed work like the old comet 2speed jackshaft that used 2 chains coming off the centrif clutch so that at only shifts when going WFO.
or act more like a cvt?

does AGK sell it or the extra tall keystock
how about the bolt and washer that holds
the driven side to the motors output

if AGK has tested it and approved it why is it not in the 99cc section?

If I read this correctly, you have a choice of 5/8th or 3/4". I was wrong,but see below link
http://www.ebay.com/itm/Comet-30-se.../330672682570?pt=Go_Karts&hash=item4cfda0b64a
At least one vender has a 5/8ths driver for the Comet 30

Greybeard , I believe both of the ones you posted links to are the rear pulley , not the one you would mount to the crankshaft .

 

[Greybeard]

You are so right. My bad. It's what you get when you are in a hurry.

There is really no way to make a 212 predator fit into a bike

Sorry, I don't know too much about the details.

Here is a pic of AGK's 79 cc 2 speed race bike from their facebook page.

There are at least 6 200 cc - 212 cc race bikes coming to the next
Grange race on April 7th

Here are 2 from AGK
The one in the back makes about 20 HP

looks like AGK is using something like this to get 2 speeds
its not a new idea was used on rupp minibikes in 1968

 

[BarelyAWake]

I think he's gotten the point, that ya can just stuff a 212 predator fit into a bike - TBH if I hadn't seen it done here, I prolly woulda said the same... should it be done is another question entirely tho lol

rode over the local harbor freight a whole 1.5 mile trip .

bought some ods and ends but if you see the 212cc in person its alot smaller than you would think very wide though i think .

for me you leave the realm of motorized bicycle after 99cc and are makeing a custom motorcycle. just my .02

 

[Fuzzy79]

Yes I deffinatly got the point, that the 212 looks beautiful in a beach cruiser. And you can go crazy fast on them to boot. I think I may have found my motor I am gona use on my bike.

It is rather wide indeed.........14" to be exact from the left side CVT cover, to the right side re-coil starter cover. You hardly notice the width when you take off with the front wheel aiming for the sky as you're sliding off the back of the saddle doing mach II from a stand still........
