I believe the 10% could be Ethanol. We have one major gas chain in Canada that uses up to 10% the corn based fuel in their mix. It's stated right on the pump. Mohawk.

 

Sounds like that in addition to having to chase EPA regs for the engine, now there is extra chasing of regs for the fuel. No wonder people can get confused.

 

Yes, it can be Ethanol but it can also be other things so I just called it a "mix". The point I'm trying to make is by adding a "mix" the stoich AFR changes. This will change the way things run and an air cooled motor shows it quicker than a water cooled motor. It effects the running of the engine and the cooling of the engine. Now anyone wonder why things are the way they are?

 

Steve; I see the light you are shining. I think I like using the term fuel "mix". Straightforward and simple. I agree with you 100% on the effects of changing the mix. No doubt the fuel mix can have an impact on the AFR on any engine. There are many ways it can effect an air cooled engine for increased detonation potential and negatively impact cooling. These are points I understand.

 

Mr. Mullen...you have mail.

 

Heywood, what duals are you running on your RG? How do you like them?

 

Hi TexasVet,
I have V&H TD's and V&H Oval Slip ons With SE AC and Stage 1 download, Since I've put on the XIEDs I couldn't be happier, Bike runs great and much cooler, I haven't checked mileage yet but the plugs have nice color. I've also switched to Royal Purple Cycle Max 20w50 wich also helped cool it down. I hope you get the same results with your set up.

Tom,

Thanks for the input. I'm running the bike right now with the TD's & XIED's. Seems to be running fine and I get absolutely zero popping like I did with the cross-over. I currently am using Amsoil in the motor and have an oil cooler. The main reason for the change-over was due to the wife and the darn hot cross-over pipe. She's in heaven now not have to keep moving her right foot away from the pipe. The XIED's and any other enrichment device ie..power commander, never really cooled the pipe enough to keep her from getting slight burning of her leg.

Hey Cruiser. They are the Bub 7's. They keep getting better all the time. I really like them. Too many V&H Ovals and Rineharts around. Mine's the only Bub 7 around and they draw alot of attention because they have a different bark. I can run them quiet, but when I get into it... They are very loud. Nice on the highway as well IMO.

Now that I've switched to VIED's, I get to play a little with balancing them out. Some have said not to run them at different value's, but it has been working out well for me. Minor adjustment, just to see how it will react. Right now I have it at 14.0 front and 13.8 rear.
Lightened up the soot alittle from the front cylinder. Seems even with the rear now after a 300 mile test run. I still haven't touched the FP since V&H sent me a map to replace the dealer Rinehart inspired base.

Running the VIED's on the sportster at 14.2 and 14.1 respectfuly with some nice general feed back from the bike and "The Dragon" (j/k... wife, but that's what I call her. She's use to it.)

 

Thanks Heywood. I'd love to hear a good sound file if you have a chance.
