2004 XL1200C Samson powerflow III W/ dB killer baffle

[04xl1200c]

Well I went to the dyno guy today he said my dB killer baffle was holding me back that if I had the more open baffle and better jets he would have no problem with my bike making 75+ Hp!

65HP & 72ft. Tq was not bad the bike pulls really strong and the AFR's where dead on the guy said I did a good job with my carb tuning. I know I didn't pull huge #'s but the bike pulls strong and smooth. I think I am done with the performance of the bike I just want it to run good. the TQ pulls really strong and it makes good HP plenty enough to get a ticket on the HWY or on a Mountain Road.

Ok i Edited the post to show what I have...

[04xl1200c]

so i put Shell 91OCT gas (FULL TANK) and i road about 38miles or so both ways to the DYNO shop and he did WOT pulls on the bike as you can see in the YT video (about 9 of them)

So i filled up with gas and i got 41mpg (my speedo is a few mph off) but still b4 i fixed the carb i was getting a consistant 36mpg or worse... so even with the DYNO pulls i got 41MPG i thought that was pretty good!

I like the CVP jet kits.

I was running lean and upped my low and main jet, and my mileage improved even with me running the crap out of it.

I think the baffle is leaving some ponies on the table
