Thanks for the reply! I didn't change any sprockets/chains from stock..Those teeth look destroyed. Are you running all #25 sprockets and chain?
T8F and #25 aren't the same. I guess the softest material between the motor sprocket, jackshaft sprocket, and chain was the jackshaft sprocket. You'll need to switch to a #25 motor sprocket or a T8F jackshaft sprocket.From the description it says: Sprocket: T8F-9T
Thanks for the help.. So I will need to replace that one sprocket where you said the teeth were chewed up, right? So I need to get a new jackshaft sprocket for sure, yes? What would be the best / easiest? I have to replace the jackshaft sprocket no matter what, right? So best to get a T8F jackshaft sprocket? Do I need to get a new chain as well?T8F and #25 aren't the same. I guess the softest material between the motor sprocket, jackshaft sprocket, and chain was the jackshaft sprocket.

Personally, I'd switch to #25 motor sprocket, replace the destroyed jackshaft sprocket with #25 again, and replace the chain because it is probably damaged and it is very cheap. Check to see if your bearings are shot too; my original ones tore up with much less abuse than that.Thanks for the help..

Yeah... it can be hard to find certain parts. That isn't one that normally receives that much wear. Maybe you can email someone at electricscooterparts.com; they carry a lot of replacement parts and perhaps it could be special ordered. You could also get a #25 plate sprocket and machine as necessary. I get a lot of sprockets from redboarchain.com. It is also possible to delete the jackshaft, but that comes with more engine load and a higher top speed if your motor can handle it. A downside there is the difficulty in finding an appropriately sized axle sprocket since the axle is some odd metric size that nothing is made for. I ended up replacing the whole axle and all rotating hardware.Any ideas where to get a sprocket? A google isn't providing anything..
The sprockets madprofessor linked are for the motor. Most of those small motor shafts are for D-Bore or DD-Bore sprockets. You'll be able to tell just by looking at the shaft or sprocket that is currently installed.Thanks for the reply and as I mentioned before somewhere in this thread.. Apologies for being clueless as this stuff is just so foreign to me..
The sprockets you linked aren't for the jackshaft one though, right? The one with all the jacked teeth? I emailed Electricscooterparts and they don't have one either so I'm hoping I'm not screwed.. I don't know how to "machine" one or anything, unfortunately..
I've gotten a lot of stuff from them too, good products and service, decent prices too. Known on Ebay as redboarchainspiderpig63.redboarchain.com
Thanks for the reply! IT's actually the sprocket labeled 2 in the picture that got chewed up.. So I can eliminate the 2 and 3 sprockets and just go 4 to 1?As I recall, you had a T8F motor sprocket (4) that chewed up your #25 jackshaft input sprocket (3). Both of those need to be replaced with #25 sprockets unless you do a jackshaft delete and run straight from the motor sprocket to the axle sprocket. Razor likes to use essentially proprietary shaft diameters, so you may have trouble finding appropriately sized hardware. You can get sprocket blanks and have them machined if need be, but the motor sprocket is available off the shelf. The motor to jackshaft (4->2) chain should be replaced.
Yes, it is possible to eliminate the jackshaft by going from 4 to 1, but your top speed will be drastically increased without a much larger axle sprocket. I don't remember if the tensioner has enough articulation to be retained or if you will have to remove it.Thanks for the reply!
