Finally Got my Tuning 99.9% Perfect.
« on: August 03, 2012, 06:32:45 AM »
I bought stock idles 40, and 98 Mains from Sirius Con inc. Everything else is stock (setting wise). I got the 4 into 2 swept exhaust, stock air-box with no cover and a UNI drop in filter. After syncing the carb's last night I ran the bike around town and it doesn't get much more perfect. Smooth through the whole rpm range. Pulls great. Doesn't smell like hell at idle. No hanging Idle. I cant believe how much of a difference the 98s made. From 90 (stock) or my 105's.

Can you post a photo of your exhaust system? Thanks twistedengineering.

They look like MAC Slip-on's? There are no tags. They are loud as hell but are baffled. I had them ceramic coated.
This is the best pic I have right now.


There are a set on ebay right now but they are pretty bad. The guy wants 75.00.
