805 cc milage

[hammersfan]

I was wondering what is the highest mileage anyone out there has on one of the Suzuki 805 cc engines ? Anyone with over 100,000 miles or 160,000 KM ?

[DrBob]

I put slightly over 135,000 miles on a 1996 Intruder 800, same 805cc motor they still put in the S50.

However, there are several different Suzuki 805 motors, and they are all different to varying degrees. Why is sort of a long story...

The story starts in 1986. Suzuki came out with the Intruder 1400 (really a 1380) to complete with the new 1340cc Harley Evolution Softails and Dynas. They also developed a 700cc version, to fit below the stiff import tariffs on bikes over 700ccs. A couple years later the tariff limit was raised to 750ccs, so the Intruder motor was bored out a little to 750ccs.

In 1990 the tariffs were gone, and Suzuki came out with a new bike, the VX800, which had a peppy, high-compression, bored and stroked 805cc motor based loosely on the Intruder’s 750 motor but with no common parts. It made great HP for a motor its size, but was fitted to the rather ugly VX800. It sold poorly, and was cancelled after less than three model years, and two of those were partial-year production runs. But the motor was too good to let die, so the Intruder 750 motor was discontinued and the bike was upgraded to use the new 805, and it became the Intruder 800. But there were a couple changes made, such as a different timing curve and an electric fuel pump, and the crankshaft was changed to make the idle a little ‘livelier’ for the US market. So by 1992 there were already 2 versions of the 805, but they were still about 90% the same.

When Suzuki brought out the Marauder, it was a differently styled bike for the same 800cc sales category, so the Intruder 805 motor was the natural starting point.

But the Marauder was to be chain drive, so the bottom end of the motor had to be redesigned to be physically narrower to accommodate this. For emissions reasons and simplicity it was decided to use only one carb, so the rear cylinder had to be switched around and redesigned to accommodate this change. Lower compression was also called for, which changed the heads and pistons. This also meant different cams, and electronics. So the Marauder 805 ended up sharing only about 20% its parts with the Intruder 805, so rather than being version III of the original it was basically a different motor.

After a few years Suzuki decided to ditch the chain drive in favor of a shaft drive. This necessitated yet another redesign of the bottom of the motor, so enter version II of motor 2. Suzuki also went with shaft drive for the new Volusia, which was physically a much larger bike than the Intruder. Cosmetically the motor needed to be larger to fill the frame, so the re-re-designed bottom end of the Marauder was modified and fitted with newly designed cylinders with larger cooling fins to give the illusion of a larger motor. The bike was geared differently, which called for a different power curve, which meant different cams, pistons, electronics…enter 805 motor number 3. By the time it was all done, the only thing that the Volusia 805 had in common with the original 805 was the connecting rods and some nuts and bolts, and Suzuki had three distinctively different 805cc motors in production. And as Suzuki decided to start painting the original motor black, there were two versions of that one also.

This Volusia 805 motor was again modified when the Volusia became the C50, to accommodate the fuel injection, a motor-mounted tool box, and different air boxes, so that would be version II of motor 3. But then the C50 805 motor was itself modified into the M50 805 motor. The M50 mill has slightly different rocker arm shafts, which required different breather covers and small changes to the cylinder heads. The M50 also uses split crankshaft bearings, which required different engine cases. So either that would be version III of motor 3, or, as the engine cases do not interchange, you could call it Suzuki 805cc motor number 4. That's seven or eight versions of 4 different motors, all displacing 805ccs. You gotta feel for the poor guy running the parts counter at Suzuki.

So your M50’s 805 motor is 90% the same as the C50’s 805 motor, but shares only some parts with the Marauder’s 805 motor and only two major parts with my Intruder’s 805 motor.

Probably more than you wanted to know…

Yes just what he said.

Oh....

[hammersfan]

Thanks for the very interesting history of the 805 motor Dr Bob. I had no idea there were so many variants of the engine out there.

[Rangerdave]

Damn!
That Pug-Dog know everything

I guess I must obey the Pug-Dog

[DrBob]

Everyone must obey the pug dog. We are all just pawns in my pug’s diabolical plot for world domination.

[wildwolf]

..and the Pug Dog gets all the chicks. I've seen him in action.

need help! got an M50 06 back in 05 but still haven't done anything to spruce it up, i was thinking pipes but don't know what to get, budget is around 450-530, navy doesn't pay enough for really good pipes

Thanks for the insight. appreciated..

I have the Vance & Hines Cruizers on my M50. Great sound, not to loud till you get past 3/4 throttle, I like the sound better than the Vance & Hines Pro pipe I put on my HD.

Use your search function, that topic has a lot of information in some other posts.

You make mention of the Marauder only having 1 carb , My 2000 Marauder has 2 carbs , when did they switch to the dual carb set up.

What does your question have to do with the milage on 805 cc Suzuki motors ? If you kept on topic it would save other members from going back to a topic of interest only to find that it has nothing to do with original topic.

The single carb set up proved unsatisfactory. So the production versions had two different carbs- a downdraft in the front, and a sidedraft in the rear- with an air injector system in the exhaust to meet EPA regs. They did eventually get the single carb set up to work with the Volusia.

That seemed a bit harsh, looks like somebody needs a time out. Poor guy is only on his second post for crying out loud, besides his post wasn't anymore off subject than your answer, and you profess to know better.


Welcome Tim Hiltz.

[hammersfan]

No my post was on topic , or rather the request to keep on topic. If I sounded harsh I apologize for that but we do need to follow simple rules of etiquette to keep the forums running smoothly. But I say again that I didn't intend to be rude, but was just making a point. But having said that I have sent a pm to Tim appoligising.
Thanks.
