Great news folks! I absolutely recommend anyone interested to go ahead and get this setup! I cannot believe how fast and easily I was able to finalize the tune on my FL400 today. Although I got real close with plug reads/chops/butt dyno, I was still a bit ways off!
Before final carb adjustments:
Throttle positions
1/4: 12.3:1
1/2: 13.4:1
3/4: 12.2:1
WOT (Wide Open Throttle): 11.0:1 @ 7300 RPM peak
After literally a few hundred feet I immediately read my 1/2 throttle was too lean for my liking; even though the
Engine sounded absolutely perfect. To make an impression, I
dropped the clip on the needle 2 positions and came out as follows:
1/4: 11.8:1
1/2: 11.2:1
3/4: 11.2:1
WOT (Wide Open Throttle): 11.0:1 @7300 RPM peak
Making progress, I
raised the needle clip back one position and the results:
1/4: 11.8:1
1/2: 12.0:1
3/4: 11.8:1
WOT (Wide Open Throttle): 11.0:1 @7300 RPM peak
Much happier me and Engine at this point. Then it was on to adjust the main jet. Starting was with a 175. I dropped the main to a 170 and here is where I left it:
1/4: 11.8:1
1/2: 12.2:1
3/4: 12.2:1
WOT (Wide Open Throttle): 12.3:1
@7800 RPM peakSo you can see I gained about 500 RPM just by leaning up the main jet slightly. The 175 main was choking it like a rev limiter and the 170 let the Engine breath more with freedom
Now for the best freaking part of this - the part that separates the boys from the men so to speak. See, I had planned on spending hours finalizing the tune on my pilot - hoping to make it perfect for the coming months riding season. I had planned on tuning in the morning, and then calling it good enough and just have fun riding in the afternoon. No need here.
It literally only took me 45 minutes today TOTAL to get this machine dialed in. New Plug chop looks perfect right at 2MM smoke ring, and the insulator is coming out nice and dark brown. Engine doesn't skip one beat what-so-ever!
So that makes two for three machines tuned in less than an hour with this WB O2 sensor. Next time I'll tune my FL350r.
GET ONE of these!
