Default Rebuild Help Needed - 82 Honda XL500R

     

Hey everyone,

First time rebuilding a bike and I am looking for some advice on replacement carbs. I am rebuilding a 1982 Honda XL500R. The carb needs to be replaced and I am looking to buy a Mikuni VM36-4. The reason I chose this carb is because I read about someone using a VM38 for a rebuild of a 81 XL500. I thought the VM36 would be appropriate as I measured the bore size on the intake manifold and it was 36mm. Beyond that I am lost when it comes to jet size and needle size. Just looking for some advice before I buy the carb. Wondering if the VM36 is an appropriate replacement and why the other person used a VM38.

The specs for the original Carb are as follows:
Make: Keihin
Model: PD 08A
Venturi: 32mm
Main Jet: 155
Pilot Jet: 58


Any advice is much appreciated!! Thanks for your time!

Welcome to ATM, I hope you find the site informative. Curious, why not just rebuild the original carb?

Keihin carbs are pretty good. I think a full rebuild kit is can usually be had for less than $50.
