Hi all, inspite of all the posts regarding the installation of Baron's front pulley, belt tensioning, wheel alignment, etc, I just felt like sharing my own recent experience with this customization. If for no other reason, then to encourage others who might be thinking about it that this is much easier than you might expect, if you have the right tools.

Grant it there are differences of opinion on all of the various aspects of this install, but here is my personal experience:

1. Baron front pulley was a drop in fit, with no scraping or dremel tool modifications required. I did remove the plastic part from the belt guide and reinstalled the metal bracket.

2. I used the markings on the frame to align the rear wheel, no problems.

3. Set the tension on the belt using a tension gauge. As per the maintenance manual, within spec 1.5 to 4mm. Belt rides very close to the left side of the rear pulley.

4. No alignment issues, no belt squealing, no problems.

5. As for effect of the change in gear ratio, the bike happily hums along at 80 km/h in 4th gear, whereas before I would need to shift to 5th at anything above 70 km/h. At highway speeds of 100 - 110 km/h in 5th gear, I no longer find myself looking for another gear.

Thanks for reading!

I had mine done when I had the service.
The belt runs on the left side of back pully needs alignment.
It did make a big difference in the gears, very rearly looking for 6th gear now.

Glad you had no issues installing it

congrats! very curious about this MOD.......do you have a vid, or where to find a good one on HOW TO DIY?

quick ques. on that:

1. what would the dealer charge including the front pulley and labor?
2. is front pulley enough? or you have to the rear at same time?

3. drop or hike in MPGs?

4. I hear that you will lose low end torque after the new front pulley, is that true? THANKS

1. The dealer will be high. I found a local shop and since it was time for tires(I bought through him) he only charged 40 bucks to install the pulleys.
2. I did both pulleys.
3. I really didn't notice a change in mpg. I did notice a change in the ride.
4. You do have to throttle up a little more on take offs but once your out of first gear your fine.
I did both with no regrets.

thanks for the detailed response

so no low end torque loss?...........b/c you said you had to increase throttle pressure to get on it, i would that would b a sign of low end loss...

so no more vibrations? at 70mph

i would just like to do either front or back, which ever is easier AT FIRST..........

any DIY VIDS?

What makes you think you need an alignment? Mine ran on the left side from the factory. Just assumed it was normal, no squealing, no issues.

Sorry, no video. There are a couple on YouTube, but they aren't great. I suspect there would be some low end loss, but hardly noticable with just the front pulley. Still worth it for the improvement on the highway, in my humble opinion.

so your saying front pulley, would be the one pulley that doesnt sacrifice must low end torque that the 900 is appreciated for?

what other mods are a must do for the 900? thank you!

My belt before was running in the middle of the pulley and now I have a slight noise which I heard as soon as I rode away from the shop

I can't really comment on what impact changing the rear pulley would have because I haven't done it. However, I have read just about every post I can find and have concluded that I should expect some low end loss if I were to change both pulleys. What I can say though, is that I am happy with the front pulley change and the almost unnoticeable low end loss. For me it is a happy compromise.

I've done a few cosmetic mods, but this is my first performance mod. This is a midsized cruiser and it does what it is designed to do very well. If I wanted insane performance I'd be riding a sport bike. The only other performance mod I'm considering would be to swap the exhaust, and do that properly, with the air filter swap, and fuel management system.

so what did you do to fix it and stop it from making noise?

as far as the belt being in the middle of the pulley, y is that bad if its centered?

thats what i am concerned a about DIY front pulley for me, dnt wana screw anythign up

I didn't do anything to get rid of the noise, as there wasn't any. All I know is the belt ran very close to the left from the factory and it runs in the same position after the upgrade, no squealing, no problems. Its probably about a millimeter or two from the left. It isn't actually touching the left wall of the pulley. Most of the posts suggest this is where the belt is supposed to run. If that is true, then your rear wheel would need to be out of line to get the belt to run in the center. Like I said in my original post, I used the markings on the frame and a belt tension gauge to set it all up. Once everything looked good I torqued everything to spec, then spinned the rear wheel, watching the belt's position to make sure it stayed where it should.

good job! any DIY to show this, not sure if you youtube has any good reliable DIY vids on this!

still dont know if i should do the front or rear,
and which is better on price,labor and yeilds a good result? Front or Back?front or

The front is the cheaper of the two, upgrades. I can't speak to which one would yield the best results as that would require two bikes to experiment on (or reverting back to original stock pulley before trying the other)

There are a couple of vids on Youtube, but they aren't great. I did watch them multiple times to see what I might be up against, but in the end, I mostly took what I read on these forums and decided to go for it. Some of what I read was useful, some though did not match my experience with the project. My initial post is a good summary of my experience.

Based on the gearing calculations, the difference between swapping the front pulley only vs. swapping the rear pulley only is insignificant (0.2% RPM difference). Compared to stock settings, changing either of the pulleys will lower your RPMs by about 6% for equivalent speeds. The front is cheaper to buy and should be less work (since you don't have to remove the rear wheel).

I don't really understand what you wrote (no offense intended), maybe a typo somewhere is confusing me. Do you mean changing both will yield a 6% change? Or each pulley will yield 6% for a combined 12%

Changing only the front pulley will lower the RPMs 6% when compared to stock.
Changing only the rear pulley will lower the RPMs 6% when compared to stock.
Changing both pulleys will lower the RPMs 12% when compared to stock.

I have changed both pulleys on my 900 and love it. It has drastically altered the vibration or buzziness at 70 to 75. I would do it again without hesitation. On ebay, you can get the front for about $140 and the rear for about $250. Well worth it if you spend anytime on the highway. I did not notice any real loss of takeoff power. It may be down a little but if it is, it doesn't bother me in the least.

Most of my riding is at highway speeds but if all I did was ride around town, I would still do at least the front and probably both.
