Has anyone got the tranny ratios for a 98 SRAD 750 kicking around? I went for a cruise tonight, and touched off 11,000 RPM in 6th gear, looked down at the speedo, and it indicated about 150 km/h... Now, just from previous experience, and sheer seat of the pants, this was WAY off... in that range last year I was indicating up over 250 km/h... on the same note, anyone have any idea where I might look to fix said problem? I'm guessing that a magnetic pickup somewhere is only receiving a fraction of the signals it should be... where is the pickup on these? I seem to remember something about it on the front sprocket.... All your help is much appreciated...

Ah, ive got the ratios, but 150km\hr in 6th @ 11000 rpm is just waaaaay off. And i think u might be right about the signal from the countershaft sprocket.

Ive heard GSXRfreak [and others] mention this... the speedo sensor might be loose at the sprocket cover. Or maybe there's something wrong with the rotor. Remove the sprocket cover and have a look and see if they're aligned.

Im sure the others will give a better suggestion, but i think most of them are asleep at the mo...

Yea it's, about, 1.75.
At 11,000RPM in top you should be doing 240kmPH or 150MPH. Is your speedo switchable between kmPH and MPH? Just a thought.

Well, for any interested, I figured out what I did... I broke one of the tabs off the "shaft speed sensor" when I had taken the fron sprocket cover off for inspection.. I completely forgot about the fact that I'd written myself a note on my workbench to replace it... Found the note today... DOH! Thanks for all your help.
