What should the top speed of a TZR without the power valve controller be? I can't seem to top much more than 70 on the speedo... is that normal?

its about 70mph, peg the power valve up and you will get 90/100mph but you have nothing below 6000rpm

Mine was pegged half way, but was still pulling at 80 on the clocks, not sure why, but now I've hooked the PV Servo up I'm hoping to see more

Got 85 on a downhill today... handlebars vibrating like f*ck, though. Couldn't even feel my hands once I'd slowed down to a non-vibratory speed, I can't imagine it would be much fun going any faster on this bike!

Its not its scary as hell the bike vibrates so bad it starts to shake your eye site sometimes it really puts the willies up me.

standard tzr full servo controlled ypvs off the clock at 100mph and reading 92mph on my mates peugeot 306 to be honest if i had pushed the bike to 100mph i would have blown the engine to pieces.

i would not go off your speedo on your tzr as there not really accurate when you giving it some leather your best getting a friend to follow you in a car or a bigger cc bike and take the reading from there speedo be more accurate than the tzr speedo.

Mine runs up past 90 (gps speed on a sat nav, not speedo reading), and is very very smooth, very little vibration
Are you sure you're fork's/rear shock arent on the way out? could cause some manic tremors at those speeds if they were playing up?

If you can find one in good condition from scrappers, the RD 350 speed is a direct replacement, goes up to 200 km/h and is more precise. Worked like a charm in my old bike

Probably knowing my luck.

How much will something like that set me back? (I wouldn't do it myself, I've been down that road and I am just not a hands-on person...)

you probably need to balance your wheels if it vibrates a lot in high speeds. The max speed I ever got with my 4dl3 was 185km/h in a downhill(slight). Just a small tune in the cylinder and proper jetting. It didnt vibrate though at all.
