IMHO the H2 fits into your description of noise perfectly. a proper motorcycle engine is a 4 stroke design not an over grown adaption from the chain saw industry and so far history has proven this .

As for "Noise", that term is usually reserved for unwelcome or unpleasant mechanical events transmitted as sound, but as for the SOUND of POWER via intake/exhaust events, that aint noise, ol`buddy, thats sweet music..

I have no use for an old Honda 4 so I don't need to be on there forum. If you read what I stated " from a pure engineering point " it is the better engine design but here is the stickler, the handling like most jap stuff from that era was rubbish. I also do not make the mistake as you put it BUT the configuration has a massive effect on the subjective vibration. Look at how different a 360 vertical twin is to a 90 degree L twin.

Bill, shouldn`t you be on a Honda forum if you rate them so highly?L.O.L.
The Yamaha R1 is an example of an in-line 4 which does not run a 180 crank...
You mistake the configuration for the subjective vibes felt,

Baron Von Budweiser, attempts to snot a certain Norton .

the Castrol Six Hour Production Race . Jim Scaysbrook . This is a Ducati Chap , so obviously prejudiced Pro British machineary . Quotes .

When the final acceptances were published, the list showed just one British bike, a 750cc Norton Interstae for Len Atlee and Bill Dillow . ( p 47 )

P 49 The 750 Kawasaki s barely made the one-hour mark before needing fuel , ( :D :lol: :mrgreen: )

On the opposite side of the circuit , a cloud of dust signified trouble for Atlee's Norton, which had cooked the front brake pads.Recovering the bike he made it back to the pits where the pads were changed.The team lost eight laps before rejoining the race - and finished exactly eight laps behind the eventual winner !.

page 59 " Had it not been for the brake pad failure that sent Len Atlee down the road and into the pits in 1972 his team would probably have won the event .
Atlee lost at least eight laps rectifying the problem .

The mathematics for this are , the time he spent removeing the machine from the scenary , had he not decked it , etc , would be the LEAD at the finish.

' Two Wheels ' mag. at the time had it that the slackers hadnt replaced the pads after practise and they were spat out going into the downhill corner .

Such is Life .
 
As 'pure engineering' the Honda 750/4 is no paragon of virtue, it is a fat boring buzzing lump.. & was no match for a Commando or H2 as a rider's superbike..
Bill, have you ever used a chainsaw? ever thought why Honda does not sell them?
 
Matt your re-imagining of the Castrol 6 hr is fanciful but funny, coulda/woulda/shoulda is all very well, but when the H2 pitted for gas, what position was it in? 1st? was it not? Obviously, racing production bikes with disc brakes was novel at the time & hiccups/Murphy moments are to be expected - I guess.
 
I just so happen to own 2 chain saw's a small poulin for light brush and a stihl. both of them are good for what they are. a 2 smoke is also a good engine for weed eater's and leaf blowers and IMHO that is where they should stay, well maybe a moped :lol: but the exhaust emissions have pretty much done away with them in most first world country's. you still did not respond to my example of how engine layout has a dramatic effect on vibration????

I loved my powerful out board motor water craft and the snow mobiles sure can make good power w/o a valve train too. My main chain saw is 6 hp and a lot easier to handle than 6 hp Brigs Stration 4 stroke. But I like living with my 4 stroke bikes better than oil in fuel engines.
 
Bil, I suggest you re-read the posts, there are factors that relate to engine configuration lay-out [V,in-line, opposed,square,radial], crank throw layout,[ usually expressed in degrees], crank length & firing events [x 2 for 2Ts obviously] that all affect vibration levels... FYI, the biggest, most powerful & efficient recip' mills are 2Ts..[ship engines]. The DFI 2Ts currently used in snowmobiles & watercraft are like-wise clean, efficient, light, compact,powerful....so, why doesn`t Honda sell a chainsaw then? ...& oil injection came standard on the H2...
 
Its actually Scaysbrooks book .

The chap that rode with Hailwood. Intresting to see the Dukes and BMs could see of a Z1 . :lol:

Canna be finding a pic of Atlees 72 Combat Intersye on the computor , so a Triumph or three will have to do . . . :)

Again, good pix, Matt, but what did the BMW & Ducati see? the black flag or post-race scutineering 'anomalies'? -like a 900cc big-bore kit in a 750? As for Scaysbrook, his level of motorcycle writing is akin to Al Crashcart's, they`re both notorious Ducati boosters who are big on hype, but dodgy with the facts. & with all your Ruski refences shouldn`t a URAL be your cup of sick?
Anyway, Old Mike T` Bike Hailwood took up bike racing again back in Kiwiland, where he retired after racing cars for the McLaren F1 team, & lived down the road from us in Mairangi Bay, we`d see him there, but never do the annoying fan thing..
 
ANNOYING .

Was a picture in NZHRM of a P38 in a F bed , and one in a Aus hot rod mag of a Rover , in the 70s . Just bare engines, unfortunately .
Trying to figure a inboard clutch & suitable fwd car trans to get sequential shift . and not disintegrate . If we do likewise . Have the engine anyway.
Simple to do a 750 perhaps , though this is basically four of them . Not entirely impractical . but will need thrust / longitudeinal loads absorbed in bearings on the left to seperate from rotational input to gearbox . :? Thats my theory anyway . Then theres the mufflers . :? Not entirely impossible .

Wont look entirely like that , but it gives you the idea .
 
Matt - Is that disgusting blob one of the pre-Commando prototypes so rightly rejected by Bauer,Hooper,Trigg et al? Or is it your own abomination?
 
Green then, is it? Must put on a thicker coat of paint to cover the excressences? Or rose-tint to the specs?L.O.L.
 
the big ship engines are a diesel type NOT petrol ( gasoline), run on bunker OIL and only turn a few RPM so it is apples V oranges and do not have emissions out put to deal with. the new direct injection 2 smokes are cleaner and I do remember the orbital which was basically a copy of a Detroit diesel on gasoline but it went no where here in the states. face it a 2 smoke is a dirtier runner than a 4 cycle by is nature and will eventually die out. as to why Honda does not sell a chain saw I am not privy to that but old man Honda was a big proponent of the 4 cycle engine.
PS a detroit diesel does not share crankcase air and combustion air like a conventional ring ding.
