2010 te 250 rear sprocket

hi everyone!!
i just got my 2010 te 250 a couple of weeks ago and i wanted to know if my rear sprocket was 50 tooth instead of 40 tooth. should there be some sought of writing on the sprocket to tell you.
if my te has the 50 tooth rear sprocket it will have the full power up kit on it. also does anyones 2010 250 lack a lot of power down low as i tried to start off on a small hill and it would either stall or pull a wheelie then stall.

cheers

if its not marked on the spocket,you may try and mark a tooth with a marker and count the teeth,based on your description I think you have the 40 on your bike,you should contact the dealer and ask them what they put on the bike when you picked it up

Pretty sure you should be getting a 40 tooth on the bike stock and a 50 tooth in your kit that goes with the bike. The 50 tooth is part of the bike kit, not some dealer offered extra. Ask the dealer about it, they may have forgotten or not really know much about.

I see your from down under so it may be different from the US. The 40 tooth was meant (along with other devices) to pass emissions testing. It is not a proper rear sprocket for your bike. 50's are normal stock rear sprockets for TE's.

In Europe thay always give you two rear sprockets and two chains.
The 40 tooth we normally call road gearing.

This is to pass EURO whatever its called emission and noise regulations.

First gear is high enough with a 50 tooth back sprocket let alone 40 tooth...

on the back sprocket is shows a engraving that shows t50 would that be what i am looking for.

yes..
