bad influence

check the plugs to track rich running.
Could be jets, could be CV carbs diaphragm.
what was your ride like ?
dragster at the light or cruising gently on the highway ?

I remember when Cycle World reviewed those back in the '80s. It was not a flattering review until they put a hot rod VW engine in it but still, I want one.

The v65 was NOT known for reasonable fuel economy.
Also, when you have a month of sundays check the valve clearances. Since they are among the most difficult (or expensive) to adjust in motorcycledom it may not have ever been done.

Heh. I just did the opposite. Out went the big bike, now have a $160 250cc. I'm sure I'll eventually right size to a 650 or 700 some day.

Yes, the brazillian boss hoss Though I'm sure Germany could hook them up with fuel injection(that runs on ethanol even)

re: 250, the buyer just picked it up last night, I took it for a ride. It handles great, but wow does it seem slow now.

I've got a wideband o2 sensor on order and have been reading up on carb theory and procedures and jet kits, maybe if I set the main jet 13:1 and the rest to ~15:1 I will get a mostly tame bike until you open it up all the way and see if it is manageable (and what the mpg effect is). There is even a dyno 9 miles away it turns out.

I've a kevlar clutch and spring on order, so I can afford to slip the clutch a bit when higher rpm power band is "needed", and can entertain exhaust and airbox mods as well (not for efficiency). It still needs to be a monster, but maybe low rpm and cruising mpg don't have to suffer.

So after a 27mpg tank, I have been P&Ging a lot more, getting used to bump starting the slipper clutch, but the whole thing is starting to slip so hoping my kevlar gets here soon, stupid store didn't actually have a new clutch spring.

A couple observations:
This thing is a LOT of fun to pulse.

It glides better than any other bike I've owned with the clutch in (yes I see the oiling diagram that has the transmission shafts fed by the pump). Heavy. I wonder if only half the plates are dragging because of the slipper sprag.

My left hand hurts.

Also the tires were low so I pumped them up to 35/40.

Altough the Amazonas uses a way smaller engine than the Boss Hoss, it's incredibly heavy. Well, retrofitting EFI wouldn't be so hard, considering that an MPFI setup was factory-fitted in the Mexican Beetle and the Brazilian Kombi, there were even some dedicated-ethanol versions. It would also be better to get MPFI instead of TBI while running on ethanol, to avoid the intake manifold to freeze and eventually get choked with built-up ice.
