Hi Larry, thanks for sharing your thoughts!
A lot of people say all the C50's run lean, I tried a K&N air filter on mine for a week to see, I simply cannot afford the new exhaust, the aftermarket adjustable chip, but I wont put the lean running (no back pressure) pipes on until it have the chip too.
Backfiring exhaust is definetly a sign of the mixture beeing lean.
These stupid clean air laws in the US are so stupid in some areas, such as no more 2 cycle lawn Mowers... COME ON it is a stinking Lawn Mower!!!!! I would be willing to bet Cattle and other Livestock Farts put more Global Warming gasses in the air..
That's true, kettle is a very big source of CO2 emmitment, they emmit much more than cars, trucks and motorcycles together. Scientifically proven.
When I put the K&N on I could hear a throatier acceleration, BUT, (and here it gets interesting), I was getting some slight popping while slowing, going down large hills etc... so off it came,
Yes, that's coming from an lean mixture, I had an sport exhaust on my scooter too, no cat and no baffle - that thing was backfiring crazy. Unfortunately that's bad for the engine even tough it sounds badass.
Now thinking on the rich/lean point, shouldn't we just run out stock Air cleaners longer OR dip a light coating of oil on them to limit air flow to do the first thing?
Possibly. I heard many times before that an stock aircleaner over time gets better at filterling smaller particles because of the holes in the filter element beeing partly blocked by filtered debris. I'm unsure about oiling the stock filter, depending on what material it is made of it might disintegrate with oiling...
When Fuel Injection had been around for about 10 years or so in 4 wheelers I noticed them lasting many more miles than before, when I asked a Senior Mechanic why? He said, " Fuel injection produces a MUCH better regulated, and cleaner combustion". He followed that with " Carbs ran a lot richer and there was a lot more Carbon deposits that caused premature wear". So this seems a bit confusing to me.
That is correct, carburetors are much more "stupid" by design, they always dump an predefined mixture of gas and air into the engine, they cannot adapt like a FI can. But the problem with FI are emmission regulations, that's why our FI bikes run so lean. That's also the reason why you need an fuel tuning after putting a less restricitve filter on or an aftermarket pipe. So while FI are simply better technology the emmission laws kind of interrupt.
I am also wondering if the higher Mileage being reported is partially due to the older age of the Bikes being reported.
Possibly, we don't have any real scientific data of how many bikes ran how many miles and how many have a died engine to compare the VL800 carburator version to the C50 FI version.
I am betting if someone comes up with #1..a mixture of Fuel and/or Additives, #2.. a 3rd party mapping and chip, the EFI motors HAVE to come out on top, if started early on. The old carbs cannot compete with the EFI for mulitple adjustments per second real time as an Engine is running. Another question is, have there been other Engine changes internally?
I agree with you, the FI engine has to come out on top. I have no clue if the engine has been internally changed, but other than the necessary parts for FI I don't think so, I mean the new C50's still have that damn non quality chain tensioner part. And till today, there's no substitute from Suzuki, I guess they've given up on these bikes. In Europe the C50 is on sale, I bought mine on sale. Why? They only reach EURO3 emission standards and have no ABS, not even optional. But for 2017 ever new registered bike MUST meet minimum EURO4 emission standard as well as it must have ABS. That's why Suzuki is phasing out the C50 and till now there's no follow up model. Same happened to the Honda Shadow 750, I couldn't get one anymore.
Also is there perhaps a desire from some who are still historically hanging onto the "old days" of Carbs.
I still remember when I was young an old H International Tractor motor that had a slight knock, since we used the heck out of the old girl as a utility Horse for small jobs, we decided to overhaul it. After tearing it down we found a small chunk of carbon was causing all the noise! That old tractor ran like a million bucks and served up for another 15 years.
I am looking forward to those of you a lot smarter on Motors than me to chime in... One thing is for sure, A lot of people are spending undue time worrying if they can get 100,000 miles on their bikes! Me? I'm just gonna' shut up enjoy my bike........and ride......
While engines from the past, especially old american V8's are known for their robustness, half a million miles on the original engine for example, I'm pretty happy that I don't have any carburetted engines anymore. How many mechanics nowaday still know hot to properly setup an carburettor? You don't learn that anymore....
People also forget that engines back in the day were much more maintenance intensive than nowadays, nowadays you can go 30.000 miles between service intervals without a single issue (except if you drive a Suzuki C50
I will drive my C50 'cause it's fun, she looks fantastic and I enjoy her. If the day is coming I can still think about an rebuild (I have an friend who is a motorcycle mechanic).
