I've been looking for a transmission for for my 4 stroke. I been trying to get a 4g with 100t pulley but I can't seem to find any seller with them in stock.

Any help will be appreciated.

Yeah it's on their website but when you go " add to cart" and you go to check out it says in small red letter below the item name

"warning 0 out 100 items left in stock"

Or something like that.
Still don't like how they play around with your feelings, getting your hopes up about finally getting parts for ur 4 stroke... Just have them crushed when half of them or not even in stock.

I have the Dax Titan 4 stroke, which is just a hs 4 stroke

They do have the 5/8 shaft right?

Also besides the bearing issue, are they good transmissions?

The Dax Titan has the clutch built into the side of the motor and does
NOT have a 5/8" output shaft.
It has the so called tapered shaft.

The Dax Titan will not work with the Grubee 4 G that Bicycle-engines.com
sells and it won't work with a Q Matic without an adapter.

I don't know if anyone is still selling the Grubee 4G gearbox that works
with a Titan. Bicycle- engines used to sell them.

The only choices you would have then are some low quality pocket bike
chain gearboxes.

Wtf!!

I'm stuck with only one type of tranny... And even those are only 3:1 reduction, which means I have to get a new giagountour sprocket in the back.
And the problem is that my 36t sprocket is stuck on my hd hub, can't get it loose.... Figured that out when I had to replace a spoke and it was in the way.

I guess you got the tapered shaft? :D

There is a single and double chain gearbox available.

Hey, maybe Gasbike has some of the 5:1 Grubee 4G gearboxes left
that fit your Titan?
The pic of the gearbox on most dealers website may not actually
represent what they are selling. You gotta call but that is a crap
shoot too.

A wanted ad on Swap n Shop may be your best bet? Good Luck!

If I get the 3:1 I'll be burning up clutches and stuck with crappy tranny lol

EDIT: nvr mind, someone moved it to the swap and shop.
