About to install a speedohealer, any ideas...

[The Big Red One]

I'm gonna go down one tooth in front....not sure how far off the busa speedo is stock.....or if anyone has info on the combined % off that the stock speedo and one tooth down together might be? Hope this speedohealer works as advertised

again, thanks in advance guys. What a board!!!

it is my understanding that by law all speedos have to be accurate only to 55 mph now i have read somewhere on this site that another guy was having a similar issue with speedo accuracy i beleive his was off (at high speed approx. 150 to 170 mph) about 7% so if it was reading 170 he was actually going 158 mph. im not sure just how accurate that is it seems to me kinda off.

mine seems to be off by 10%.

The Busa is off by approximately +8%. If you go to the SH website you can plug in the +8% factory error and then account specifically for the sprocket by typing that in to the calculator as well. No need to come up with combined percentages, it is a pretty neat tool for setting these up.

All that is fine and dandy, but you will need a GPS or some other instrument to measure your true speed in order to know if you're actually going in the right direction or not.

Just have a Harley ride next to you. Their speedo's are dead on.

Of course, they'll only be able to verify your speed up to about 110, and you'll have to give them time to get there. I know...I own one

Why can't Suzuki, in all of their engineering wisdom, make a friggin speedo that's accurate? That is a good question. Maybe I'll e-mail Suzuki.

Your Speedohealer will correct your speed to correspond with the smaller front sprocket. One tooth down in front is equal to about two and a half teeth in the rear. I prefer to change the rear sprocket as it's much easier on your chain. I went up three on the rear and it made a difference of about seven percent on the speedo. The Speedohealer won't correct the inaccuracies of the suzuki speedometer. One speedo may be off in one direction and the next may be off in the opposite and one may very well be right on. The speedo's vary with accuracy but they will all be within 7%. You can adjust your speedo to be deadly accurate at 70 mph and it may still be off at 150? Just the nature of the beast. I set mine up to be accurate at 70 mph and have found it is still pretty darn accurate at higher speeds. If you don't have a GPS or radar gun to set your speedo with, the next best thing is to hit the freeway and set it by the mile markers. If you cover ten miles on the freeway and adjust it so the mileage corresponds exactly with the mile markers, you'll be awfully close. Your tire will also make a difference. You can adjust your speedo healer so you are right on with a new tire and as the tire wears out, it becomes smaller making your speedo read fast. Or if you set it with a worn tire and put a new tire on, your speedo will read slower than your actual speed. Hope this helps you some!

Its called the "Thrill Factor!!"

Probably saves lives by making guys think they're faster than they really are. For the rest of us who know about it, its just a pain in the a$$!

ding ding ding ding.... we have a winner!



of course zuk and the rest of the mfg's can make an accurate speedo..... but they wont.

Thanks for all the info guys.....its helping alot

I don't need my speedo deadly accurate...but I'd like it close, hopefully closer than stock. My GPS has no freeze frame option for my mph.....so instead of trying to look at the friggin' thing as I'm riding I think I'm gonna use it to verify the accuracy of my wife's speedo then pace her to check the Busa's. Wait, actually I'll put her in the Firebird...then at least I can pace her to 160 anyways eh?

......lol
