SV HPT Gearing?

16-45 was perfect on my first gen, put me at 9100rpms at the top of alpha

but that IS one heck of a motor...

How big of displacement is it?  I was thinking I was getting more than 9100 out of both my SVs(1 was stock, the other was a 677), but I've had a few concussions since then:) 

FWIW, I always paid more attention to how the bike came off of corners when selecting gearing much more than where I ended up at the end of the straight.  Obviously no gearing is going to work great coming off every turn, but I'd pick the gear that worked the best at most turns and the most important turns(leading onto straights).  Everything is a compromise and with this in mind, I'd try drastically different setups to see what would happen, and I was suprised to find things work that I thought wouldn't, and conversely.

Jim-glad the gearing worked out for you.  You doing the Mothers day TD?

I hope everybody had fun and was safe.  Race reports would be awesome for all of us wanna-bes!

G-Baby Racing will be doing a practice at Hallett for the May 21 5 hour CMRA endurance on the 7th (CCW).  I'll travel home that night and will try to come up Sunday (20 min from my hose to HPT)

its a 677 probst built engine, the gearing was just about perfect everywhere only place i was between gears was 7.

With a Probst built engine, it will probably pull hard off the corner with about any gearing.  If I ever got back to racing SVs, I'd be calling Ben to have one done right.

Of course the rest of the expert grid would prefer you keep it stock jack...

Thanks for the kind words Jack.


Our 1st gen bikes specifically use some different gearing. We rarely run a 15t countershaft as it has us realing through the gears a little too much. My 1st gen stuff doesnt use much revs either, as Joe mentioned they like to be shifted below 9500, as opposed to 10 and up to 11 on the second gen bikes.
