DavidNM, This group is seeing quite a few new owners to used C10's which is great. Along with that is a recurrence of topics such as air pods on the carbs and other mods that will hopefully add 50 HP to the bike so it can run with the sport bikes - which ain't
NEVER gonna happen.
Do you like to perpetually work on the bike through trial and error (which is great if you like that kind of thing) or ride your C10 in the best known nick available?
If you haven't yet R&R'd your C10 carb bank, you will find its bit of a chore.
If your answer to the above is the latter, then what the fellas are telling you is what you need.
They don't sell anything and are giving you the best time tested C10 answers and solutions to your questions to save you from trying to learn this on your own the hard way rather than getting 'er done the first time in the right way and enjoying your ride.
If I was going to mod my carbs, the first thing I would want is better mileage. Sometimes it gets 43 mpg, but sometimes it drops to 37 maybe from a headwind. This is normal, but I want it better if possible. Has anyone machined the seats in the throttle slides to drop the jet needles .025" or so? I think that would improve mileage, but maybe not if it adversely affects throttle response. I would have to try it to find out unless someone already has and would tell me.
Your numbers are almost exactly the same as my C10 in the same conditions. MPG can even vary between different C10's on the same run. Lots of variables there. A 14% drop in fuel mileage for a sporty run or a sustained 80 mph freeway run into strong headwinds costs pennies in additional fuel cost. Owning a motorcycle, even a C10, has so much more cost than that.
I don't believe the answers should be secrets. If they really want to help people, tell them the answers. How many times should someone be paid for some work done 10-20 years ago? Sooner or later I would say enough is enough.
You want something for free that someone put blood, sweat and tears into development - not knowing if they would ever see a return. I wouldn't keep showing up to work if I had to do it for free all of a sudden. That would be worse than getting fired.
You can play with the carb settings to infinity - nothing wrong with that. It is extremely unlikely you will find a better solution than what some seriously talented people have already worked through over a period of years / decades. I can't even imagine the hours and costs involved.
Trying it your self or paying for already tested and developed work is your choice - neither of which is wrong.
Demanding option 2 for free, not so much.
