R850R Hard Cold Starting, Intake Backfires

I know it's not a GS, but maybe you guys have some insight. My 10k mile '96 R850 is pretty hard to start when cold and when it does, it won't idle till it gets decently warm. I'm at a loss on what to check. Any ideas?

Vacuum leak?

Fellow R850R Owner

I know that this is not the wisdom of the ages, but...

I also have an R850R , bought new in November 1996. The only time I have had any difficulty starting was when my battery was low. It tested okay with ignition off and then cranked , but could not hold charge. New battery, problem solved. Always takes some time to warm up at fast idle or better yet, just ride away.
Have you consider ethanol problem somewhere in fuel system?
