I recently aquired a xplorer with about 2300 miles. Had a lot of deep engine work done however the vm34ss carb was worn out. Bad needle and seat, worn float arm, worn floats, missing middle plate, missing pilot air jet, and the threaded plug in the bowl was corroding away. Since the oem carb assembly is no longer available i hopped on dennis kirk in search of a vm34 carb with a close configuration. I found one with the idle speed screw on the rh side and it looked perfect which was the vm34 275. I removed the float bowl on both carb and transferred my needle jet, slide, needle, main, pilot and spring over with no issues, all factory specification parts. Float height was correct out of the box which is to be expected with a genuine mikuni. I did have to redesign the airbox boot to keep the oem airbox. I used a 2.5 to 2.5 ID silicone intake boot from vibrant performance and shortned it to reach the airbox when everything is compressed. The intake side if the carb is larger and requires a large hose clamp to secure the silicone boot to the carb. It was slightly bigger id on the boot than the od of the carb but samwiched perfect, the silicone also had a nice gripping effect. Ive only had one start up and ride on this configuration but it runs like a new machine had no bogging issues or idle issues. Plan on doing some plug checking under load to be sure. This is to hopefully help some that have worn out oem carbs.
