No. I meant *Crank* HP. Pay attention to those who know much better--the many Guzzi tuners with experience over the last 40 years who hit walls at around 85-95 RWHP for fully tuned race engines with fly-like lifespans. I did not say *anything* about beating Ducatis. The point is that our '60s-tech engines are quite pathetic in HP races and are nearly fully optimized ex-factory. To really make it obvious: Nothing you do to any Guzzi will make it nearly as fast as a stock, used, $4K Yamaha R6. You'll just make your poor Guzzi suffer and far less reliable. Guzzi big blocks *are not* innately high-performance engines, but, can be tuned to do quite well somewhat against the original-ancient-design parameters. They have too many insurmountable power bottlenecks to overcome.Where's the "room for plenty of improvement?" Remember to post your Griso's before/after dyno charts from the same dyno once you're done chasing whatever it is you're chasing. Proof of the pudding and all that. Remember, the Griso engine was fettled as far as reasonable by some seriously great engineers with Aprilia/Piaggio money--and 75 RWHP is what they arrived at all tings considered.Intelligence requires that you trade your 2V for an 4V Griso if you want a faster Guzzi. It'll cost you a fraction of the $$3-5K+ you'll need to get 85 RWHP from a 2V, and you'll still have loads more torque and power from a far more reliable engine. And, for the price of a decent Guzzi race engine, you can have a Ducati with 60 more HP and 20 more Ft. Lbs. of torque.

I, however, understand the appeal of improving one's own bike even if it won't be "a Ducati with 60 more HP." Seems to me the lack of intelligence, or at least of understanding, is elsewhere. Nothing forces anyone to move to a Ducati or similar just because you think that is the only intelligent thing to do.
For some reason a fruit salad sounds good right now Dusty
Seems we are in an era where innovation and hot rodding are discouraged , and dumping our ride for something with more power is the preferred intelligent method over hands on hot rodding. Argue for limitations, and they are yours.
The 1100 Sport is a great bike, but it hardly is maxed out from the factory in top tune. Yet somehow, that 1064 2 valver with Dellortos would run neck and neck with a Daytona 4V at top speed, dyno fiqures be damned.

In a straight line the vaguely stock (stock they were an almost unrideable tuning mess so not many are actually stock) 1100 sport will run out of gearing and rpm at about the same time an A kit daytona and only the A kit will run out of grunt and aerodynamics, I seriously doubt the 1100 sport can pull any taller gearing. The C Kit motors as fitted to the Racing and RS will piss all over it, a well set up Ducati 1000DS (two valve aircooled motor) will also have it for breakfast.
..Love the bike, though I'm getting a little too creaky to ride it.
The carb'd Sport 1100 engine is my favorite Guzzi engine, of all the ones I've ridden.With Staintunes and Keihin FCR41s, it makes the right kind of power for the chassis. Love the bike, though I'm getting a little too creaky to ride it.
....and the logarithmic increase in valvetrain stress and pressures from using higher lift cams with more duration.
I suppose you meant to say "exponential"? Logarithmic increase is less than linear.
not the use of sheer will to overcome physics, such as gravity.
" To really make it obvious: Nothing you do to any Guzzi will make it nearly as fast as a stock, used, $4K Yamaha R6. You'll just make your poor Guzzi suffer and far less reliable. " I don't agree with the above statement regarding Moto Guzzi top speed ( Fast ? ) potential, and that's where the argue for limitations quote was mentioned, not the use of sheer will to overcome physics, such as gravity. So how fast is a used R6 ? Been around engines and Guzzis for many years , and will just say, I`ve had different experiences with what a good cam will do with a well designed engine package. not based on lack of understanding, but experience. I`m still always learning though, especially when it comes to drinking others koolaid.
Agree with you Pete , my LSR would make a terrible street engine, not much bottom end, and not designed to go 100 K miles. If it did, it certainly wouldn't be competitive. I`m not suggesting James turn his Griso motor into something like my Lemans 1000 , but I do believe there is meat on the table for improved performance without sacrificing reliability, that's all.. My LSR engine has never had a full rebuild , but it is probably due for one. Back to my question, How fast would a Guzzi have to go to hand a can of Ass Whoop to a used R6 , street legal or not ?

I have no idea... the Guzzi would also need more gearing as most of them run out of rpm and gearing around 230kph mark unless its a Griso that annectdotally its all over by 180kph (possibly only the two valve version).
