That seems to agree with what I'd expect. The reason I don't really know is I've made it a habit to never check my mileage when I'm having a fun time carving up the twisties. There is no point in spoiling the fun with practibility. Your Mileage May (And Probably Should) Vary.

Yeah, the phone is a 1986 "special edition" of the phones we had back in those days. I could tinker with it so it will work with modern digital telephone exchanges.... But these days everybody calls me on my mobile.... And it being January, it was time to do a stock take on my other hobby... and I still have a wee bit left from my 2016 Ace Of Spades Baltic Tour!

I had an RF900 for 18 years, they are a good solid machine but a little uninspiring next to a V4. Have a look at the emulsion tubes in the carbs, mine wore oval over 50,000km and the fuel economy went to crap (plus fowled plugs at low revs) but it was an easy fix.

By the way, doing "the usual snorkel-flapper mods" isn't really a great idea. Yeah, there's a lot of back-and-forth argument on this subject but I can tell you that 99% of the guys (maybe even 100%) who argue in favor of this modification have not read Chapter 21 of the 1998-2001 Honda VFR800FI Interceptor Service Manual, which is entitled, "Technical Features". If you were to carefully read (and understand) the information Honda has provided in this chapter you would realize that disabling the flapper valve and messing with the snorkel is a counterproductive effort. I'm not going to try and explain the whole situation here in this post to your forum thread, but the most important piece of information contained within Chapter 21 is that the VFR800 ECU runs in two different modes, depending on "demand" (which is closely, but not completely, related to throttle position). In conditions of low demand the ECU makes its fueling decisions primarily based on information provided by the Manifold Absolute Pressure Sensor, and in conditions of high demand the ECU makes its fueling decisions primarily based on information provided by the Throttle Position Sensor. Now I'll leave it to you to carefully read and understand the Chapter 21 information and by doing so come to an understanding of why the snorkel and flapper are installed on the engine (and why the Honda engineers programmed the flapper to open and close when it does).
