There is another transmission made for the 79cc Predi. a EZM "Q-Matic and I have one boxed in my machine shop.
Lynne of MBrebel sold me mine with the intention that I get it to work in the Sportsman Flyer frame. It was a bad idea. There was bad blood between her and Pat.since Lynne started bootlegging his wide pedal crank assembly. She was unapologetic and that was it.
And that is why I have a EZM "Q-Matic trans waiting for an application. I got one of Lynne's bootleg wide crank assemblies in a box in my shop too.
Was in the shop for a couple of hours today getting the front fender mount for the springer fork sorted out. Another hour will get it done. (photos soon) and then got the next 41b13 sprocket loaded in an emergency machinable collet and made one pass with the boring endmill. Tomorrow is supposed to be rainy so I will get more done. I really have to get the Flyer on the road before snow flies. I ain't getting any younger though I do my best to ignore the fact. Have fun guys!

Tom, I have the wide pedal crank for the 49cc engine kit and it just about cleared the CVT transmission. I also ordered a wide
pedal crank from BikeBerry and it didn't come close to clearing the transmission until I took some heat to the crank arms and
made them clear it. I burned off the nice chrome finish and now they are painted black. :)

I hope to see you get the EZM "Q-Matic transmision on the bike and hear your review or report on how well it works
with the 79cc.

Thank


Thanks Steve I appreciate the help. Though it's not my favorite thing I can lace a couple of wheels if forced. I'd prefer 1/2" axles & sealed bearings, but I'd accept 7/16" or above.

EZL I've bushed the 5/8" shaft on a Lifan 98cc as Curtis suggested and I used the 3/4" Comet CVT. It works well on the test stand, but my other projects preclude mounting this setup on a bike at this time.

Tom I'm running myself ragged this summer with bike upgrades and just normal maintenance stuff. Seven motorized bikes that are ridden frequently and comprise 90% of my daily transportation needs year round are labor intensive...not quite like keeping a 'copter flying but at least a bit every day. Needful things they are and me the enabler! Still it's what I do and I'm still having fun.

Sounds like you are really busy keeping things going! This area doesn't have many fellas building and riding motorized bikes.
There's a town about 9 miles away that I did see a fella who had a 2-stroke bike pulling a cart and as big as Bloomington, Il.
is I only know of one retired fella building/selling 2-stroke bikes. The fellas around here like the HD stuff which are loud and
I doubt if anyone of them would know the difference between a "boxed-end" wrench from a "open-end" wrench!

Has anyone messed with putting a Lifan 125cc 4-stroke semi-automatic trans/engine on a bike? I'm wondering if there's room?

Don’t see how if it is done right with proper key and proper set screw setup, set screw should go through the bushing onto the shaft..........Curt

Hart to tell since the images weren't very good in the pics. I suspect that a lot of problems are caused by not tightening correctly
and a host of other variables. One fella was running a light bike frame with a 212cc, no shroud on the CVT in a off road area.
I don't see how the frame held up and what would have happened if the belt would have broke at the rpm he was running it.

I seen some reviews where some fellas had problems with using the bushings. I am surprised that Comet hasn't got one
for a 5/8" Predator engine.

Quentin Guenther of EZ motorbike was having bushings made for the 49cc 4strokes. He was reluctant to ask $15.00 for one but ask a machine shop to make one.
I have never heard a negative comment about Quenton.
I gave him a call a couple of years ago, Real nice guy, background in motorcycle racing.

After a brief thunderstorm this mourning, to celebrate completing 50 years as a Tool and Die Maker my wife and I took breakfast at Diner 67 in Lomira, WI.

Once home into the den of labor. First job bore the 41b13 sprocket I.D. to 770" so as not to drag on the pedal shaft. Then faced down the hub to 250" height ( this is the offset I hope will bring the drive chain into line with the drive sprocket). No mounting holes yet.
Yesterday, I made two 1" high stand offs for the front fender stays and bolted them up and I had more than 1/8" clearance with the axel fork so today I faced off .125" and still cleared the fork by at least .062" which is huge in a rigid assembly. Next were the rear stays and I knew it would be challenging and it was a bit. Not cutting 45 degree corners on the end of the stays until I made the cuts. But it is done and stiff and steady.

Home from work I sat down to work on finish reading another book while imbibing two Founders Brewery's
All day IPS Session Ale and chatting with my wife about tomorrow's replacement of a 1983 furnace and AC plant.
Then down to the shop to get something done.
I completed the front fender installation by drawing up and locking all fasteners. That done I put the 41b13 sprocket in the mill vise and zero'd it in. Ready for tomorrow when I get home from work. I will drill and ream the bolt circle.
From using my 24" Lufkin blade I think turning .030" off the hub will make the chain line right and I am really getting tired of all this trifling around.
Tom.

A foot note, August 18, 1969 I entered into apprenticeship as a Tool and Die Maker. Fifty years have passed. Today was another day at work. I knew the trades were a way to get ahead. The personnel manager was a Minister of the Baptist persuasion. He asked me if I wanted to get a draft deferment and I was on board as in H**l Yeah!
Got my 1H classification. Served a five year apprenticeship to get my Journeyman certification.
I stayed five more your years out of dedication to what
Furnas Electric gave me.
Ray Nystrom was my Master.
He was wounded at the Battle of the Bulge. I owe my lively hood to him. God let him rest with those that died before him in WW II.

Got sidetracked from the bike making some extensions for the jaws on my band saw.

DSCF0812[1].JPG

The stock ones didn't get within a inch and a half of the blade which meant I couldn't saw anything less than 3" long. I oughta be able to cut a quarter offa half now.

Of course another option on short stock is a parting blade on a lathe, but not on mine! It ain't big enough. Every time I've tried it the lathe gets mad at me and goes HONK!!

Bikes looking great & taking care of the trifles now means less walking home later.
