Now that I have my Beemer (old but golden K-75 RT) to ride, guilt in me said I really needed to fire up the wife's 2000 EN500 C-5 (Vulcan LTD) so that we could go riding together.
I knew those Keihin carbs respond poorly to long periods of not running. So I bought a set of jets (from CarbJetKits ™ [carbjetkits.com]) and surprised myself how easily I cleaned up all the parts, replaced the pilot and main jets and added a spacer that came with the kit to the main needles. BY FAR the biggest pain in the ass is getting the pair back in place, both the squeeze past the manifolds and getting the throttle cables hooked back on.
Battery charge, oil change and she fired right up!
However, the engine still bogs when you get to about a quarter throttle, and if you insist by further opening the throttle, acceleration is sluggish, punctuated by the occasional surge as a hint to how quick the bike should be.
Everything is stock. I have the petcock on PRI so I know the carbs are getting fuel. What to try next? Could the air filter be so dirty she can't breathe? (Will look at that tomorrow).
Any ideas much appreciated.
