Hi Jon,

1998 TX250, She kicks up first time! she ticks over fine! when ridden for about five minutes she don't seem to want to tick over without altering the tick-over adjuster, then she seems to be lingering on the rev's but still ticking over when stood. My reeds look burned slightly on one side also a little warped, could this possibly be causing it? I have looked up the exhaust port and the piston looks fine,the plug seems a little dark but not overly! I have ordered new reeds which will arrive in three weeks. Everything else is I think as it should be (coolant e.t.c.) can you give any other advice???? Thank you for your time and for all the trouble shooting advice on the G-G site...pretty comprehensive!

The symptoms you describe sure sound like bad reeds. Worn reeds will cause a hesitation (which mimics low-speed jetting being off) when the throttle is opened. Make sure when you install them that you don't overtighten the screws. Use a little blue (serviceable type) Locktite on the screws and some non-hardening sealer (like the Silicone types) on the case/reedcage/manifold junction.
