more upgrades then riding lately, never stops snowing here. just found out my local bike shop can supply a tm 36-68 with an assortment of jets, and they gave me a number for a custom cable guy if needed. what i need is some input from riders with similar set ups. part numbers as well. i ride about 3000 to 6500 feet, 09 klx 250 with 330 big bore, twin air with snorkle removed, powerbomb header and q4. mostly bush riding with no hiway. recommendations to save a little time would be great. only want to order once and dont mind having a few parts laying around. away from the computer for a few days for work but cant wait to hear what you guys have to say.

 

Look up the HS40 manual online. It will give you details on jetting. There are also a few threads that specifically deal with this carb. Plan on changing jetting a few times to get things right, no other way. Luckily you can do some of it while it's still on the bike, but it's also not hard to remove either since it does not fit tightly. Nice elk.
