Klx 110

[newatthis]

My son's KLX110 runs well only if I leave it on choke. When I take off the choke, it sputters quite a bit, especially in 2nd and 3rd gears. Any ideas on what I should check first?

I would try the carberator, might be something with fuel(intake of fuel)

Try the easy things first. :)

Try a new spark plug first. It might have fouled a plug.

If that doesn't work then maybe the carb.

If it only runs when the choke is on, it sounds like it's lean. Fuel starvation, even.

If after the new plug, it still does that, try cleaning the carb.

Rotorranch has good point I try install a spark plug first

Has the bike been seating for a very long time if so get Berryman B12 Chemtool Carburetor Cleaner Pour Can just pour in 2 to 3 cap full in gas tank it will clean out the carberator by dissolves gum and varnish from inside the carburetor with out take it a part just run it with choke on and off 10 min each time.

Clean the card the right way, just get a can of a good cleaner (CRC, Berryman's, etc...) and disassemble it and spray all the passages and parts (be careful not to get a face full from blowback).
