ok, I have the stage 4 kit, 58mm throttle body, 10.5/1 comp. se cnc heads, valves/springs, 259e cams etc.
bike rode like crap with the break in tune and put on dyno to get it dialed in, used hide out hd in Joplin mo.
room was 45% humidity and 90 deg outside.
Engine was struggling in the 2500-2700 then would come on at 3k. He got it dialed in and really struggled with the se259e and he said the se120 engine has the same cam and struggles with it too.
when I say struggles I mean its either make shit loads of power but be light switch down low in your cruising range or just the opposite.
He ended up hitting 107.6 hpbut pulled it down to 101hp-111tq to achieve a ride able bike like I asked forwasn't looking for a # on the dyno just wanted a safe ride able bike for the lady and I.
at 2900-3000 rpm the clutch would slip for 400 rpms then catch and reel back in the curve. He said that I wouldn't feel that on the road most likely as this clutch isn't old and has the heavy spring in it.
what do you guys think? I'm thinking a smoother cam for decent nd rideablitly? still has a little pop in it around 26-2800 rpm. not to bad though. Its a little rich right there for the 3k curve where the cam comes on. he worked and worked on that to make a smooth transition.
this was a dyno jet and the SAE was 1.05
this site wont let me attach any pictures today, have been trying all day in the classifieds
I'm not a Dr. but i'll take a look
