XR600R

[Honda90 0]

My son has an XR600R with a Mikuni 41mm vacuum carb; it's junk. He's looking to replace it without spending a furtune. Wondering about the TM40 pumper that's used on the DR650. Anyone have any experience getting one jetted for an XR600R. Any other suggestions? We're sorta desperate - his current carb is totally unreliable, and we're doing the Eastern Sierras at the end of this month.

Thanks!

Basically plug and play.

But remember not to chase your tail, and make sure all other parts are good to go- vacuum leaks, carb boot, carb manifold, air filter, valve clearance,fuel filter, valve seating, compression,spark plug,ignition, good fuel,exhaust clear, etc etc etc

Wow. Thank you, Robert. That looks like the way to go. The motor has just been torn down and reassembled to replace a broken case. So all valve adjustments, etc., are fresh.

This carb has been a problem since he bought the bike last year. It runs like a banchee, and then it will suddenly not do more than about half throttle - sputtering and leaking gas out the over flow. He just cleaned it and is reinstalling it right now. We'll see.

Thanks again!

he may want to check the float level (adjust).

also the float valve assembly can leak a tiny bit causing overflow and partial flooding.

and a crack or small tear in the main slide diaphram can cause it to not accelerate well.

look inside the mouth of the carb when pulling open the throttle if the slide isnt going up when running.then it wont accelerate well ..

if it is still is over flowing after the carb clean the i suggest a new float valve assembly..(make sure you need one first though before ordering it.)

where are you guys located?
