Feedback on 426 hard starting
Posted August 14, 2006 - 07:05 AM
I live at alt 4500, and got the bike with GYTR pipe + header. The prev owner said he had it jetted, but I doubt it.
I have the hard start, 1/4 throttle stumble and high idle only.
My wife has a CRF230 that idles like a sowing machine, but my WR just wont idle low for long, so I keep having to gun it to keep it running.
As soon as time allows I will pull the carb (never done it before), clean the inside (the float chamber (?) was clean on Saturday) to see what size the pilot jet is, and buy+fit on size smaller.
Did the light blue wire conversion, but felt no real difference.
more cents to follow

Make sure the valve adjustment is in specification.
If the previous owner had the bike in storage for some time start with the carburetor.

You don't have to remove the carb for main or pilot jets.
Just loosen it, and rotate it, then take the cover off the bottom of the float bowl.
It only takes minutes.
Don't know about were you are ,but i ended up using smaller pilot than standard,was hunting and stalling with standard pilot jet, a right pain.
Now it idles perfect.

the 3 jets at the bottom were:
pj - 40
mj - 165
other jet - 65
The screw at the bottom was turned 3 times out
The jets seemed clean, but I cleaned it with carb cleaner aerosol anyway.
Also cleaned everthing else incl the slide.
Had a look at the slide, seems fine.
Changed the oil (but not filter) for the first time since I got the bike (I did 360 km).
Oil was black.
Also, I measured the amount of oil that came out, and it was approx 2000cc!!
How is that possible since all oil capacity posts indicate 1300cc - 1700cc, if I recall correctly?
Well I put in 2 liters of Mobil S1 semi synthetic 15w50 which is what I used on my Honda Blackbird for 70 000 km without a single problem.

Bike started 3rd kick with choke.
Took it for a 6km ride, and it seems back to normal, but still idling higher as eng temp goes up.

When they get tight they can cause starting problems.

My tech skills: can do oil change, chain change, sparkplug, carb dismantle.
What tools would I need for checking valves?
