Could you answer a few questions about carbs?
Posted: Fri Feb 14, 2014 12:29 pm
I understand the basics of how carbs work but have some questions
1. Is it correct that the pilot jet controls idling and just above idle, the shape and height of your needle in the main jet effects midrange area and the main jet size effects the top end area?
2. What exactly are you doing when you balance or sync carbs (if they're the same thing) and does this effect your fuel mixture at all?
3. When you screw in and out your pilot air screw, does this only effect it on idle or does it change fuelling through the whole rev range?
4. How do you set up your pilot air screws?
5. Would I get noticeably more power if I was to change the air filter and match the carbs? (Read below)
6.if I did change the air filter and carbs would I be able to get it running smoothly and we'll on my own or would it need to be dynoed?
My bike is standard except for aftermarket down pipes (might be micron, not sure) which are 4-2-1 63mm diameter and a sp engineering can which is 63mm bore, about 25cm length with no baffles (it's basically a straight through pipe)
It runs fine with standard air filter and standard carb set-up.
Thanks for any help
