Good luck on a carb'd bike, which is what we have here....

 

It is generally accepted that decel popping has no affect on performance, nor is it detrimental to your motorcycle. It is annoying, however! While I've spent a good deal of time ridding my vrod of decel pop, here's another way I try to look at it.....watch a sports car race - even the most highly tuned engines have decel pop - **** some of them even spit fire out the exhaust - now that's a rich mix! Maybe you're driving a race car...

 

Octane vs burn rate.




.

 

its a normal thing if you have anything other than stock pipes. I think it happens to everyone that switches pipes.

 

I dont know what jet sizes I have currently, I bought a 45# to install but after playing around with the mixture screw, I didnt think I needed since the bike ran fine after playing around with the screw. The previous owner does not know either. Today I played around with the screw some more and to me, it seems to be affecting 0 to 1/8 throttle, exactly where the popping occurs. Unfortunately the popping still occured after going passed 3 turns. I am guessing its not a fuel problem. #1 because of what i just said, and #2 because when i start the bike and i have the choke/enrichener out and its cold outside, it still pops

 

Thank you, your one out of many which is not a hater on this post lol

 

Thank you. I like you, your a funny guy lol

 

It is a property of chemical composition and how it reacts during combustion..... yeaaa....next time you try to act smart, make sense atleast... I dont even think you know what rate means, sorry

 

Yes, that is true. However, my previous definitions still stand, burn rate is independent of octane. The reason pump gas with differing octanes burns at different rates is because it actually is composed of different additives/fuels. This means the burn rate is dependent upon the mixture of those fuels/additives, not the actual octane rating.

A pure fuel will burn at a specific rate. When you add additives, such as those used to alter the octane rating, it can decrease/increase the burn rate of that fuel mixture due to the differing chemical properties. This does not automatically mean a higher octane rating gives a slower burn rate. It merely shows a correlation between the two, and as we all know correlation is not causation.

I seem to have started a horrible trend here. My mistake. I was under the impression you meant backfiring in the exhaust, not decel popping. Disregard what I said as it has nothing to do with your problem. As for getting rid of decel pop, that can usually be fixed by adding a bit of backpressure. Maybe add some lollipops if you don't have baffles or check the condition of them if you do. As I said, sorry about the misunderstanding.
