changing sprockets

[cb750]

I've been doing a little research on changing sprockets but staying with belt drive. Does anyone have experience with a higher final drive? How does it affect the bike other than higher rpms on the highway?

faster acceleration

Do you have a 12 and youre looking to put a 9's primary chain & sprocket in it?

I have a 12 and was thinking of the primary or belt/sprockets. (easier)

Yes I'm looking for faster acceleration, and make it easier to pull wheelies.

:edit: I linked to the wrong post, the one I wanted talked about a CR pulley being a bolt on affair and having 5 more teeth, the Baker front pulley is minus one, and a belt is available to fit with the stock tensioner.

If you go with Only the Outer Sprockets. The larger the slower the take off but higher end results On A Stock Bike. The RPMs will not Change with only outer hardware being changed. Changing gears will be a little different.
Make sure to Use a Hand Impact to Remove the Rear Wheel Bolts and Replace them. If you use a Air Impact go easy on removal so as not to pop the head of the Bolt off. Save your Stock parts all of it. Watch how you take off on rough Pavement due to Clutching is slightly different . Might want to get an extra Clutch Pack kit also. Go easy on it out the gate. Once you get used to it it will feel normal. Have fun with it.*Jimi [cool]

be aware when you change the rear sprocket that much you're going to have to use a different size of belt. I looked into it a long time ago, basically I found that it'd be a lot easier to go with a chain drive. I have the stuff for a chain drive just never went to put it on and someone moved the chain and forgot where they put it. I've just been too lazy to go try to find it.

whatever you decide to do, good luck.

Only the front one, and yes the rpms will change.

What I was interested in was will the overall will the bike be much different?

That was one of the links I posted, lengths and part numbers.

I hate chains, thats why I wanted to stick with the belt, and it would be easier to change back if wanted to. Not to mention probably cheaper than finding a xb9 primary.

I opted for the 26 tooth Baker aluminum front sprocket. This sprocket does two things, it lowers the gear ratio whci makes the bike "feel" like it ha about 7% more torque and it takes off faster but the aluminum is also 2 pounds lighter which has the effect of lightening the rotating assembly which aside from unsprun weight is the best kind of weight to lose. The bike pulls harder and spools up faster. [up]

Stock rear pully and what size belt?

Also you have a link please?

Yes I should have been more clear about the RPMs. You won't really notice the Change on the Tach Except the slight faster up shift and it sweeping depending on your shifting. Now if you only change one Sprocket A Tooth or so that will slightly give you a faster take off of about Approx.,4 to 6 miles per hour depending on like the Stock one Front]is Stock(27) and rear (65)teeth go lower and a little faster(one)sprocket.
Two Large Sprockets will slow you down at take off.
However She will Stand up like a Horse too!And have Slightly Higher top end, as far as [Different] you may notice the speed but handling is the same Except in a curve on entry or Exit but with practice you will adapt quickly to that. I've done some Sprockets mostly the front one cause they couldn't get it loose, and bring the parts and Bike to install. Never put them on the dyno after the install. But they come back by and swear it is a 4 or more miles faster at accelleration.The Grin tells it!
Union can tell you since he has done the front one.With one tooth difference from Stock. Up here where it snows I would be somewhat undecided to put bigger Sprockets on unless I was having fun in the Snow.Like out in the grazing areas. Then it would be fun as Frack!Ahh, time to get back to work. Have fun with it.*Jimi

sorry guys i know this is a old thread.but can i just buy the baker 26 tooth for my 2006 xb12ss and use the stock belt? seems like one tooth smaller in the front would be about perfect for me.

No. I didn't initially intend to go with the adjustable idler (but am pleased I did now despite the co$t). I even went with a new belt with on stretch I had too much slack.
