3rd gen speedometer/sprocket changes

Since there is no Speedo Healer for sale for the 3rd gen bikes, what can I do to keep my speedometer reading the correct MPH if I change sprocket gearing?

Simple answer. Dont change the gearing.
Honda has it best for road use already! You wont gain anything in reality.
Faster acceleration? Your faster and more nimble round corners from 0-70 than a CBR1100 blackbird already!
You will never out gun the latest CBR's, GSXR's, R6, etc etc...

New standard chain and sprockets adjusted properly is most beneficial.

loose the top box! they make your bike wobble and handle adversely!
Spend money on good rubber. Re-new the rubbers in your brakes, polish the pistons. Loose some weight, that will help. Im running 520 chain and sprockets now, standard teeth and im very happy with my performance gain.

Yeah, no easy fix for an old mechanical speedo.

A workaround is a bicycle computer. They are numerous but a good known brand with reasonable prices is Sigma. Besides a very accurate speedo, it will also give you an additional trip, highest speed, clock, plus more. It attaches to a fork leg and reads a magnet attached to the front wheel.

More expensive: GPS

Have some custom gauge faces made: have a look at this thread

He wasn't asking your thoughts of the bike he was just askin a question on how to do something to his bike not yours.

Jeez, a simple question is what I asked and I get a lecture about my bike, my riding skills, my motorcycle knowedge and my welding fabrication and top box use.

WTF?

Don't ASSume I am a noob...I have ridden over 100,000 miles on just the last 3 bikes I have owned in the last 5 years, doing all the maintinence myself.

More expensive: GPSI have used CatEye Velo 5 computers on 4 or 5 motorcycles now. They read up to 199 mph and are $10 new...got two of them in the toolbox right now. I'll throw one on if it comes to that, but just looking around to see what options I have other than that. My main concern is the actual mileage accumulated on the odometer. I don't want it to read more/less than the bike really has if I change gearing.

I'm currently having Throttlepimp make a tach face for me, this is certainly something he could do and a great job of it at that. However, it won't help with the odometer. And, if you decide to change back you'd have to switch it out again.

Please excuse my ignorance.
Ive made no purposeful assumptions on your riding experience/skills. My attention was drawn to the reasoning of your question.
I spend far to much time reading on this site and enjoy in offering ones own opinion on a thread to see if it leads anywhere worthwhile. Even if it may occasionally come over a little tongue in cheek, its not wholeheartedly intentional, in the pursuit in VFR excellence. Not forgetting that i have invited you into my own front room.

I read your question as what could you do to keep my speedometer reading the correct MPH if I change sprocket gearing? A good question, as I've spent many an hour looking for a practical solution.

I think i was trying to establish, if out aloud on the thread (sorry) what you were trying to gain from changing the gearing? As i have found that there is no straight forward fix.

Ive spend a lot of time changing speedos and gearing. Am afraid the simplest way to keep the reading accurate for the road is to leave it as it is.

My intention is not to tell anyone how to ride a bike, or which bike to ride(so long as it is a VFR, lol). But looks as tho once again ive gone over the top trying to bolster the excellent way Honda has the VFR bike set up already!

There is no easy fix to adjust the speedo after changing sprockets. Ive tried a few ways including cycle speedos', which have always been inaccurate and unreliable for me. GPS being accurate, costly and needs removing from bike if left in public for any length of time being the only solutions practically available.

If you do find a simple, accurate solution let me know! Selfish i know, but its a recurring issue that even i after 15 years of VFR modding, have no definite answer.
