any idea what type of piston was reliable fuel saver in term of same throttle opening ? any comments on those two types of carburetor?

about the old model sniper i think it uses a piston type on other hand the new sniper mx was using a diaphragm type carburetor. what is the difference? any another info? according to net info piston type was reliable gas saver rather than the diaphragm type. because you can control the flow of fuel. about the diaphragm type atmospheric pressure is the base line for the flow of fuel.


any inputs? experts are gladly welcome to comment.

thanks

i use mikuni BS25 diaphragm type carb (sniper mx 2011) + stage 1 cams + open pipe for my sniper 2010 & my gas mileage improved from 140 - 145 kms (stock mode) to 160 - 175 kms per full-tank of unleaded gas...

as for my experience, Sniper MX's carb, w/c is a diaphragm type got busted as early as 11 months of usage. it's not that it is unusable already, but it is already a pain in my butt. the response is not so *vrrrrrroooommm* anymore but its like a delayed response. my trusted mech said that's the downside of a diaphragm type carb, easy to get busted. can't believe mine bugged down for just 11 months of usage, normal usage. no races at all.

but the positive side of a diaphragm carb as i have heard, is that it is not "gulat-gulat" type, if you open the throttle fully and at a fast rate, it will not drown or sound like it is choking. but in the piston type, it will. sometimes, the engine will die too, because of that. and as i have heard, too, the piston type has an advantage of a better fuel consumption rather than the diaphragm type. happy to help if ever. :thumbsup:
