I bought a 2002 VFR recently, 25000 miles, very clean, all original. I work at a HONDA shop and originally sold it when it was new. Do to health reasons the original owner brought it to the shop for me to sell. Unfortunately the bike had sat in his garage for about a year without usage. He did ride it to the shop, however it was running poorly. I put fresh fuel in it and ran it for a couple of miles and it was not running on all four. Removed spark plugs, number three and four were fouled. I removed injectors and cleaned them. Number 3 injector needed replacing, also changed oil, had fuel in it do to stuck injector. The engine starts and idles great, and when it is cold before it heats up to operating temperature runs well, after it warms up it has a stumble from just off idle to about 2800 seems to clear out and again at around 4500 rpm, runs great above 5000. Any Ideas on troubleshooting would greatly be appreciated
