So I had this new engine built probably 2 years ago, and its had at the MOST 4 gallons of fuel through it. The last time I rode my R at the dunes, I was playing with the jetting...but got too nervous about rising coolant temps to really get on it. (I was jetted with DGH 2nd to 3rd clip down, 175-185 main, 50 pilot.) Later I did realize that my temp gauge (in line from radiator to engine) was resting on the pipe (maybe falsely increasing my temps?)
Anyways....toys have sat un used since
Fast forward to today. I mix up some new fuel (50/50 110 VP and 91 pump, 40:1 Klotz R50) dump it in and the bike fires up on 2nd kick! just won't idle for longer than 30 seconds on its own, seems to run boggy low/mid but hits good up top, and smokes a lot! (much for than my stock bore 250r that i fired up today as well)
Im looking for a little guidance as the which direction to head to get this engine tuned!
As it sits right now:
1986R
Fresh bottom end when 330 kit installed.
ESR 330 power vavle, TRX9 porting
Pump gas dome
ESR TRX5 pipe w/silencer
Stock electronics (cdi, ignition, stator)
NGK BR9ES @ 20
38 A/S carb
DGH needle @ 3rd clip
185 main
55 pilot
screw 2-3 turns out
did a leak down test and it passed with flying colors
cold compression #'s (verifed by 2 gauges) 150 psi (too low?)
I feel like I remember it running best with the clip 2nd down from the top, but its 112* here in PHX right now so Im going to wait till the sun goes down before I try that out.
Thanks!
