If you fall a stranger will walk on by, a friend will help you up, a true friend will laugh and say "Been walking long?".
PS Don't miss the notes on CycleX. #1 not recommended for stock frames. #2 Made for SOHC but "will fit" DOHC.
(a lot of things will fit in the hole, most won't make it run well LOL)
Now I know your just talking about replacing the carbs, but your leaning towards major changes.
As AMC has pointed out in other posts, first you need to open the holes before trying to shove more fuel in. In other words, a better flowing exhaust is the place to start. After that would be work on the head, porting and polishing makes a world of difference along with some modern valve seats and guides. Then you toss on some bigger (total cfm) carbs, might need to change the fuel petcock and fuel lines, and don't forget the ignition!
In other words, think of the "entire" system.
Me, I'm an old mechanic. If it works don't fix it. But it hasn't always been so. I spent thousands on my first Camaro rebuilding it from the ground up even though it was in near perfect shape when I got it. So I know what drives people to re-engineer their bikes. Just remember to consider it as a whole, not focus on just one part.
And give us pics, we love pics!
