My 110 would be very uncomfortable heat wise until I went to Freedom Performance True Dual head pipes. Very dramatic lowering of heat on the right side of my bike. The ECM on the Rushmore bikes will self adjust for intake and exhaust changes. xieds can be added if you feel the bike is a little lean. Hope this helps.

 

You will be happier with the sound with the cat out.

 

 

 

You wont regret it, note the heat on your right leg now with the cat, then report back about the difference with the cat gone.
Highly recommend a quality dyno. That being said, you might want to take time to consider a performance upgrade and use the dyno to pull it all together for you, you know, consider all perimeters; more in, more out, and more juke while it's in there.

 

Actually the opposite is true. Introducing more air and keeping the fuel (as well as timing and a couple other tables) the same will result in higher temps and usually poor running condition.

FWIW, a "high flow" air cleaner will do nothing for most any stock bike. The factory A/C flows far more air then the motor demands even at WOT. Unless one makes significant changes to the intake, throttle body, heads, pistons, header, and exhaust, a "high flow" air cleaner will provide no results.

Sorry, I know that goes against most aftermarket claims but just read their fine print and look at the all the data runs out there. No major modifications equal no need for a "high flow" system.

 

 

Sorry my friend...removing the cat and changing pipes are still well within the capabilities of a stock HD air cleaner.

I'm fully aware that most aftermarket A/C manufactures state their system allows (or will accommodate) for "X" amount of CFM's (airflow).

Try this...there are about 1700 cubic inches in a cubic foot. If the engine is a stock 103 and it's running at about 3000 rpm, the air flow is about 180 CFM's. The stock HD air cleaner is rated at something like 500 CFM's. The max airfow for a stock 103 at 7500 rpm is about 420 (according to some of HD's air flow figures).

Installing a system that will accommodate air flow over the capabilities of the stock engine will not cause the engine to suddenly increase it's max CFM air flow. It's going to take major modifications to the internals of the stock engine (like I said before, intake, pistons, and the such) before a "high flow" system begins to be effective.

Now if someone wants to add one of these systems to their bike, then I would certainly not stand in their way. It's just that many such aftermarket systems boast of significant increases in power and performance over stock but fail to mention (except the very small print) that engine modifications are really needed to see those same gains.

Hope that helps.
