Please give some advice if you can.
Ill start by saying I don't want to run my bike lean. I would rather go rich and not worry about damaging the engine.
The bike 07 400 ex. Mods HMF exhaust, K&N stage 1 power kit.
The way the bike is setup.
I upped the pilot to a 140...awesome! STARTS LIKE A DREAM.
I followed the direction for the kit...which setup as a dj146 main jet.
fuel mixture out 3.5 turns from seated.
Again exactly as the directions state from dynojet for my alt.
The bike runs great...
My only concern is that it might be too lean. How can I tell that? Both by pulling the plug...but I want to know what to look for when im on the bike to indicate this. It seems to have great power.
When Im up high in 3rd or 4th gear and let off the gas... I may get a slight grumble or hickup out the pipe...but its not a full backfire at all...i would better describe it as a "burp"...and it doesn't happen on every decel...
My reason for concern is that the engine does get pretty hot... I do not sit and let the bike idle...only for the 5 min warmup...Im running 10w40 honda oil...going to use 20w50 but they were out. Also the slight grumble im talking about. ...I don't know if its enough to worry about.
So give me some advice so I can dial this thing in perfectly...if there is such a thing! :)
Instructions I followed:
"STAGE ONE INSTRUCTIONS
1. Remove top carb plate. Remove the slide lift arm screw and the two
needle plate screws. Flip the linkage forward and remove the slide
(Fig. A).
2. Install Dynojet needle on groove# 3 for applications below 5000 feet,
groove #2 for above 5000 feet, using all stock spacers. Install the Dynojet
washer above the E-clip.
3. Remove stock main jet. Replace with the Dynojet Main Jet Adapter
(DJA001). Screw the Dynojet main jet provided into the Main Jet Adapter.
If you are running the stock exhaust use the DJ142 below 3000 feet,
DJ138 from 3000 to 6000 feet and DJ134 above 6000 feet. If you are
running an aftermarket exhaust, use the DJ146 below 3000 feet, DJ142
from 3000 to 6000 feet and DJ138 above 6000 feet. Be sure that the jet
you are changing is the main jet.
4. Locate the Fuel Mixture Screw (Fig.B). For 2005 models ONLY use the
tool provided (DT008) to adjust the mixture screw. For 1999-2004
models, use a flat blade screwdriver. Turn the mixture screw clockwise
until it seats, then turn out 3.5 turns below 5000 feet or 3 above 5000 feet."
