Had to recalibrate mine this morning,put a 200/55 rear tire on and indicated speed was 60 while GPS was a steady 62...first time I've ever seen a Busa's actual speed higher than what was indicated.

That is a surprise! I'm going to have to break down and spend the money for a SpeedoHealer or at least mount my phone where I can see it for GPS/speed. I hate to get passed when my speedometer is showing 80-ish (which is really between 70-75) when I'm going down a 4 lane road. I love the way the Busa feels planted and smooth even as you reach triple digits but I'm very conservative in areas I know are well patrolled by the county and state cops. I know if I'm in a line of speeding traffic, or worse, leading it, they'll ticket me and let the soccer mom's fly right on down the highway in their mini-vans and SUVs. That's just the way it goes around here.

I really like mine, but there seems to be an art to getting it calibrated correctly
I seem to be able to get mine within about 1% which is probably as good as it gets,and try to be on a level,straight stretch of road(pretty sure going up/down hills and around curves will kill the GPS accuracy as supposedly it measures correctly on a flat road,in a straight line between points A and B?).That's what I remember reading somewhere anyway,sounds logical but I don't know for sure.I remember with stock gearing/tires speedo read about 6-7% high,then when I went to a 44T rear sprocket it read about 9% high (then added the SpeedoHealer and got it calibrated as close to actual/indicated as I could).With 5,000 miles on the 190/50 rear tire(wearing down the circumference)and then going to the 200/55 rear the actual/indicated mph seemed to be off about 3.3% so used that as my correction factor.Gonna go out in the morning and see how close I have it,should be pretty good.

I also had that one on my '03 and seemed to work ok.
Why the change brother ( in tire )

No good reason bro,just the meatier look.

Around 60+ works the best for me,still may be off a mph or 2 around 100 but that's probably a given.

Guess around 140 does not matter it it accurate or not. Your going to jail for anything past 12 O'clock anyway.
That's true.

I don't know what's up with me/mine,used to have it right on the money but have been fighting with it for 2 days and about 10 test runs(6 this morning)since I switched over to the 200/55 tire(knew I should've left well enough alone
).Following all the steps(can be confusing)I either seem to have the indicated 5mph faster than the GPS @60mph,or the indicated 3 mph slower than the GPS @60mph.I keep going to the calibration page and getting the + or - numbers right according to the chart,follow all the steps it tells me to follow(as closely as I can,sometimes misleading as it'll tell me to push one of the buttons until it's blinking when it's already blinking...so do I cycle through or just go on to the next step,etc.?...have tried both methods!).I must've missed or added a couple steps once as when I started to move at about 2 mph the speedo pegged and stayed there until I came to a complete stop,thought I'd permanently fuked up my speedo and was really pissed until I re-calibrated it one more time and it went back to normal.Right now it reads 63 actual mph by GPS when it's doing 60 mph indicated on my speedo and I'm burned out/tired of fooling with it so gonna leave it alone for a few days 'til I regroup.When I thought my speedo was permanently screwed I came within an inch of finding the biggest BFH I had and pulverizing that little bastid into oblivion.Isn't technology to the point where manufacturers can just link a GPS to a bike so we don't have to go through this aggravation(they can sure as hell incorporate it into a billion damned cellphones)?Screw motorsickles(
)for the rest of the day,I'm goin' in to watch me some Gunsmoke.

Are you resetting after each run so that your speed difference is based on 0? I did the same thing. I kept changing and it kept being off. Then I realized I wasn't getting the reading from a 0 setting. I reset the speedo, got the difference and then put in the recommended numbers.

I think so bro,each time I start over I believe it's from 0 but this weekend when I try it again I'll triple check it(has to be something like that I'm missing though).

I now trust mine more than the GPS. My current GPS has a slight lag before updating. It took me many adjustments while stopped on the side of the road to get it right. A few were just .1 at a time. I'd imagine it'll require a bump every 1k miles or so to adjust for tire wear.
It was an odd sight when it actually read low. Mine is set ~ -6.5% with factory tires, stock sprockets.
Watch for that C on the indicator. Mine got set in conversion mode on accident during one of the adjustments.
I think it's still a couple mph over at 60 mph, but I decided that was better than it being low.
