Pilot
Hi all
I seem to be having problems with my idle as in i cannot get one,the air screw has no effect and when all the way in the bike will stall. Have checked for air leaks and the jetting is:- 2004 ec300 Pilot *42 main *178 Needle cck 3rd clip There is snow on the ground at the moment so quite cold,I thought i might be rich on the pilot but worried about going lean,it also stutters at very small throttle. Cheers Macho |

I don't know how "cold" cold is or what the altitude is where you are, but what you have in there is "typical" summer 70 deg. F. sea level jetting. Good chance you are lean unless you are high up. There is a good rejetting chart based on temp and altitude in the manual and description of how to apply the conversion factor. I had the exact same summer jetting with air screw out 1.5 turns. I just rejetted mine for ice riding (last ride was sea level 15deg. F.) and went by the chart. 45 pilot, 188 main, dropped the clip one, air screw in one turn. It runs good. Previous time out it was about 28deg. F. I went by the chart and corrected for 32 deg. and it was a tad lean and bogging on accel., but dropping the needle cleared it up. For that temp the correction figured as a 43 or 44 pilot neither of which were available as far as I know so I'll probably leave the 45 pilot in there for winter to be on the safe side. Quote:

I'm guessing you're lean off the bottom. Try a 45 or 48 pilot, air screw probably around 1 1/2 turns out. What's your elevation?

I'am at sea level and have tried the air screw all the in and all the way out,looks like i'll be ordering a 45 and 48 pilot.
Thanks for the quick reply...Macho |
