Keith,
Keep in mind that the 16t + rolling hills = lots of people on your back! I switched back to the 15t due to the lack of power on hills (I have lots of hills in my commute).

I find that on most hills I want to be somewhere between 4th and 5th. It's too wound out in 4th and laboring in 5th. I was thinking that the 16T might make 4th just right for long uphills.

That's exactly what I thought when I had a 16T.....including a round trip through the Smokies.
I didn't ride it stock long enough to have a good feel for what it did on hills......'cause we don't have many around these parts. :)

Part of the problem, I believe, is people who are used to cages that never go over 3K RPM.....and are afraid of winding the little 250 out a bit.

just put the 16tooth on the tu250x. it was an easy process, i didn't need to put it on stands either. took about 30 minutes. rode about 30+ miles around the city on it tonight including 80mph on I-5 - with wifey as passenger. no problems whatsoever.

what a great difference. i believe that the swap makes the bike a much more "capable" bike and puts a broader range on the gears overall. less shifting down the road and a much more tolerable rpm at all speeds. I (and my wife) are not heavy ppl by any means...total weight being around 245lbs. max recommended weight for the tu is 355.

awesome. :rawk:

Interesting results. Usually the GZ will sacrifice a little speed for lesser RPM with the sprocket change. Maybe the FI makes a difference.

Wish I could get parts that quickly. My speedo cable snapped a month ago, so I ordered one straight away, from the local bike shop. It arrived last thursday! :cry:

I don't know if it's been mentioned in this thread already, but you should NEVER use a torque wrench to loosen a nut! Use a breaker bar, or even a large crescent wrench (which is what I used to change my Marauder's front sprocket), but NEVER a precision instrument like a torque wrench!

Re: Install a 16 Tooth Front Sprocket
 
Hey guys, after reading this tutorial I was inspired to try this mod.

Unfortunately I'm stuck! I can't seem to get the 16 tooth sprocket properly hooked into the chain to mount. I don't know if bike bandit sent me the wrong piece or if I'm doing something wrong, but no matter how much I've massaged the chain and sprocket I cant get it back onto the bike.

I noticed that the teeth on the new sprocket don't quite seem deep enough, as the chain isn't fitting/gripping fully. Is that to be expected or do I have a bad part? Thanks in advance!!

I loosen the back adjusters and axle nut.
Then I push the chain down with my foot, to get the back tire up as far as I can.
Pull off the 15t and put the 16t in as high as it will go on the chain.
This should give you enough slack at the bottom of the chain to pull with the sprocket enough to slip it on the the splines.

The teeth should look the same as the old sprocket.

Hope this helps.
