Still Makes the popping sound
Hello everyone. On my 06` 1100 i'm still learning new things. From the original owner I've gotten the receipts of every major service. I was lucky I know. Since i'm a new owner of the bike i'm trying to get all the services reset for a date that I can put down on paper. My bike has cobra pipes, A K&N filter and nothing else that i can tell modded with the engine other than a oil relo kit. I am getting a ton of useful ideas on this forum...You folks rock.
My AIS sucks. I want to remove it. For now I just got done doing a full oil change\tune up plugs etc.... since I had to remove the rear tire I also gutted the acc panels. I relocated the air pumps hoses in the classic U pattern. started it up and I have a rough idle. the popping sound isn't as bad as before for the de acceleration. has anyone else done this quick mod and still have 80% of the known ais pop? should I check the sync of the carbs? If I eliminate the AIS completely will it stop all the popping sound?

Hmm? I wonder if the previous owner changed the carburetor jets when he did the exhaust and the intake air mods? The mechanical gurus on here talk about that quite often. Mr Rcom is one of the guys that could help. You might need to PM him to get his attention.

RE: Still Makes the popping sound
The popping sound on deceleration is most likely a lean condition. Simply removing the AIS may help somewhat but is not the cause. Did the previous owner re-jet the carbs after changing the exhaust? The first and easiest adjustment is the pilot mixture screws(pms). They should be set at approx. 2 1/2 turns out. If that doesn't do it turn them out another 1/4 turn at a time to see if that will cure the problem. Check out the V Star Wiki knowledge base page. Tons of useful information there. When you say you have Cobra pipes are you referring to Cobra Slip Ons or a complete Cobra system? If it's a complete system you should re-jet the carbs. There's tons of info about re-jetting available with a quick search or two. Be patient, make one change at a time and you can do this.

RE: Still Makes the popping sound
hey, most on here will say if you have a aftermarket exhaust system that the AIS has to go, it is a easy enough fix and save a few pounds too as well as cleans up the engine.


i say this as mine had the cobra system, had never been jetted, did the jets, that only improved the performance, did not help with the pop at all, removed the AIS and keep Startron fuel treatment in the fuel due to the ethanol and have no pop now.

Not sure if the previous owner did the rejet. I don't wanna assume. Yes it's a full set of pipes (not just the tail pipes). any thought to the AIS? should I just remove the whole system? Lastly....on the pms, is there a cap or anything i need to drill off to gain access too? I will look it up but for now easier for me to just ask?.

edit.......Rain or shine I ride so my bike doesn't just sit. Should or do I really need to add a fuel additive\stabilizer?

As long as you're riding enough that fuel doesn't sit in the tank for more than three or four weeks tops you should not need a stabilizer. You could probably go longer than that but our tanks are so small that temperature swings are wider and I prefer to play it safe.

If you are in a humid climate and especially a humid client with large temperature swings it's best to keep the tank no less than half full to reduce condensation. Actually, this is probably good general advice in any climate.

If you are only riding a handful of miles a week to keep her from sitting then you should probably fill up any time you are down a gallon and use a little stabilizer.

Fuel driers and additives aren't needed routinely on bikes that are ridden regularly. A lot of people don't realize that for all that alcohol in gasoline gets a bad rap a little bit of ethanol (not methanol) is actually helpful. Alcohol is anhydrous, meaning it absorbs water, which then gets carried into the engine and burned (actually, pushed out the pipe as vapor, but you get the idea). Back before they started adding a little ethanol to gas it was common to buy the "fuel drier" additive...which was often just ethanol in a can. LOL

The only time I use additives like Sea Foam is if the bike is exhibiting bad behavior, such as after being laid up for several weeks last winter.

Startron is not a fuel stabilizer, it is a additive as the current fuel is so eco friendly that it is not friendly to our bikes, mowers, etc, have a bud that keeps it in all his toys, bikes, boats, jet skis.

If you're going to disable the AIS, you might want to remove it completely to clean up the bike. I'm not sure I know what PMS is in the motorcycle world. Undecided Bikes that are ridden regularly should not need fuel additives but, you will get many different opinions on what a motorcycle needs. You can go nuts trying to do everything recommended. Ya gotta sort through them and determine for yourself what makes sense. Rolleyes

RE: Still Makes the popping sound
till i was laid off i rode 5-6 days a week, experienced slight popping then at the advice of the local shop mechanic in a casual conversation got the Startron, just add couple ounces every fillup, sounds great all the time now.
