But they can be noisy vs an enclosed primary, bearings are more exposed to elements, jeans or boot laces can get caught in belt.

^^ Yeh you have two things going on here:
1. you changed your primary so the different ratio here will affect the gear indicator, 6th light
2. you changed your secondary from belt to chain, and this would affect your speedometer and mileage reading.
For #2 the fix is easy with a powervision or TTS, and updating the 'speedometer correction' pulse per km value. you would figure out the ratio difference from stock in percentage, then add or subtract that percentage to the stock pulse per km value. I don;t know if the fp3 can do this. I can help you get the correct value if you can get a tuner with editing capabilities. I think you may be getting beyond the fp3's capabilities with your mods.
for #1, you may need something like the PV or TTS so you can edit the actual 1st-6th gear ratios. I know that baker has decent tech guidance on fixing this but not sure about BDL. i'm afriad this area is not one I'm familiar with but I have seen it posted a lot that changing the primary to belt drive will f-up the indicators, 6th light, and cruise control. it may also affect abs operation. you may want to post for some help on HTT forum as well.

1-On the primary change,your thinking the ratio on the belt is different than stock?I'm guessing the first 3 gears are low enough to not make enough difference?
2-On the secondary end,would this be controlled by a different speed sensor?I thought the 24/51 ratio was pretty close to stock(unfortunately)?
I'm familiar with the PV as a Powervision tuner,not sure what a TTS is?
I'm going to AZ Bike week next week,maybe I can find some reps there to help a brutha out.I can see already my work here is not done.

I'm about to install a BDL belt drive on my Rocker, and was told that it wouldn't affect the 6th gear light on my stock speedo...and yes, the FP3 does have a "Speedometer Calibration" feature, in the edit maps "General" section. It might fix the problem. BDL also told me that gearing changes to the ecm wont be necessary after install..also are you installing a belt guard and front covers on yours?? or did you order without?? I ordered the 2" polished model.
As for the guards,I got the polished also,but am running it open for now until I can decide what to use for the guard.Not really a fan of covering the pulleys.Liking the open "hot rod" look.
Thanks man.
I hear ya splattt,hopefully not TOO much pant shredding.Thanks dude.
Thanks dude!

BTW, even with my large change in primary ratio my speedo is dead on.
As for leaving all the guards off... You'll find out how much a new belt costs if a stone pops in there - it can blow the belt right off, or in the case of the BDL's aluminum gears - chew up the gear.

BDL & Primo have different mounting positions for their covers, but I don't see why you couldn't adapt them. It might involve a bit of drilling & tapping. BDL looks to use a 2-post system for theirs, while Primo uses 4-posts.
