Topic: So how fast do you rev your 750?

I can't believe no one said "feel"...

I think that's what rtb above meant.   My 550 cafe does not even have a tach, I shift by sound.

I shift by sound and feel.  It ends up equating to 6-7.5K RPM with my 550 and about 7.5K or so with my 836.  I might short shift when the motor is warming up.  Feel the load and listen to the motor.  Lugging them by shifting at low RPM does not good.

Don't know how i missed that....

I find that 5-6K is a good breathing zone (just made that term up) for my 750 SOHC.

I agree with the other folks too. Every engine has a slug zone, breathing zone, and a ratty/stressed zone...in that order.

Relaxed riding, 3000-5500. Having fun on twisties, 5500-8500. I try not to rev it higher but it wants to keep pulling and have hit 9500 a time or two. Next time I have cause to have the motor out I think I'll be changing to heavier valve springs since this engine likes to rev. Figure it's cheap insurance to keep from bending a valve. I know the rods are a weakness at high RPM but I don't think it's a problem until 9k-10k and up. Without other motor work to support that kind of RPM I don't think it feels very natural to stay at throw a rod revs as power tapers off.

You won't hurt your engine taking it to redline, but if you spend a lot of time above 6k I'd go through the oil pump and replace the seal and orings on the pump and other oil passage locations to be sure you have maximum oil flow. I'm OCD about that stuff, but my engine is fresh and I've done all that so I flog it pretty good when the mood strikes me.

Naw, stocks rods are fine until you get above 836/849 in all likelihood.

Valve springs are a good idea if you think you'll miss a shift at 10,000. I know

Tachometer is a new old gadget on my bike. Smashed it 1982, used the bike until 1990 and shifted when it felt right. Speedo needle stopped move
New old tacho back on bike last year, road test this year 2014.

I just ride it for what it is, no real big revs these days just enjoying the ride and the scenery

I can't believe no one said "feel", you can feel what the engine is doing so change gears when the bike wants it, as in, not when its loading up like going up a hill, but when the bike is pulling freely, not when its struggling to pick up revs, I always believed that Tacho's were for dummies, its not hard to feel where the engine is comfortable and when power drops off, or when its laboring. Am i expecting too much...

My (VF750 electronic) tach died earlier this summer and I haven't gotten around to swapping it out for a good one yet. Honestly haven't missed it at all. Just like RR said, you can feel the engine and when to shift. For me and my 550 that's when the power starts falling off.
