Newbie, what brand of windscreen is that? Any issues with buffeting?

You were correct about the throttle bodies being different. I ended up purchasing on eBay throttle bodies for my 01 ($120) and then a set from a 98 ($100) model because it had the interchangeable fuel rails and injectors included. We cleaned the throttle bodies and serviced the best 4 injectors then re-installed only to discover there was no power to the fuel pump. Out it came again, repair and test the connection mentioned plus the 4 to the injectors then re-install. Pleased to say the bike is running much better, especially when cold. Thanks for the help, now on to a more compact muffler. My previous 5th gen had a Two Bros unit which growled like a small block V8 but they are pricey.

This is my 5th VFR (3rd 5th gen) and the throttle response is erratic. It bogs down at 4,000 rpm sometimes but the surging is the biggest problem. Previous bikes were linear in power with predictable boost around 7,500 rpm and fully powered up at 9,000. My new 2001 sat for a couple of years before I purchased it. I've changed plugs, gas, oil and air filters, switched to synthetic oil, flushed the cooling system with little improvement. About 8,000 miles, mostly highway with 4 tanks having Techron additive in the past month. Not sure if o2 sensor eliminator would help before I tackle the throttle bodies and injectors. I checked the stator at 12.75 on the bench then approx. 14.5 with the bike fast idling. Running out of summer...….

My 2001 5th gen problems are being addressed by starting with throttle bodies complete with fuel rails and injectors. There are multiple units available from a 98 or 99. The part number is slightly different. Can anyone tell me if it will fit or what the difference is? Thanks, Dennis
