No doubt the Leo full system wakes the bike up and I agree, it appears it wants more fuel on the big end. I can't get my mind around a $1000 exhaust for this bike though...
I messed with the bike again today and am feeling a little better about things now. I wondered if I had a fuel issue and that turned out to be the case. The "Unleaded Fuel Only" sticker on the tank led me to believe that premium was unnecessary so I've been running regular unleaded (every other vehicle I own that requires premium says so). Everybody but me probably knows this is not the case. So I removed the 87oct and refilled w/ 93oct. Well that made a big difference. The bike is still lean but is much happier w/ premium. That made me wonder if it would like even more octane so I drained the 93oct and refilled with 100 LL (av gas) I keep around for my chainsaws. It also likes the 100 LL. Still need to add fuel but it's going the right way. NOTE: I'm not suggesting you run 100LL, I tried it because it has the effect of richening the bike up. The cats would not like the lead.
The other thing I did was test with/without airbox divider. No surprise the divider costs hp (but did smooth the curve).
So my best pull today was with the 100 low lead.
And finally I pulled the 630 and put the '09 KLX250S on. I was very happy with it making a little over 20hp. Everything I've seen reported said 17-18hp. Below is TE and KLX.
