Default Re-dyno after fuelmoto inserts/sheet hits the fan!

Had the beast re dyno'd after installing the 6" inserts from Fuelmoto. Made a HUGE difference & solved most of the early dip in tq. See sheet comparison...

The inserts definitely improved your torque at low RPM and I'll bet you can feel the difference as soon as you roll on the throttle. Your peak tq is 131 and that's impressive for a stage 2 build!

I couldn't believe the difference the Khrome Werks HP-Plus insert made on my bike. I put the stage 3 kit in my 107, it has the S&S 475 cam and the S&S Sidewinder 2-1 exhaust, it ran really good but I would always play with inserts before I put the 114 in my bike and never noticed an major changes...only for the worse if anything. I had to grind and drill new holes for the Khrome Werks insert since it wasn't really made for the S&S MK45's (which is basically what the sidewinder is). That insert didn't do anything for the 107 so I put it on the shelf and forgot about. About a week ago I saw it and figured I would try it in the 114....I was blown away by the way it changed the power, it gained soooooo much low to mid torque and didn't lose anything on the top....that I noticed anyway. I haven't had it dyno'd and don't really care to, it hauls *** and runs great.

Yep! That M8 114 motor LOVES back pressure! I can tell you that you only gained. You didn't lose anything by installing baffle inserts in a 114 motor. Enjoy, I am!
