I'm at 192m above sea level, so should be no big difference from manual. I was sure, that on idle, when throttle is closed, there should maximum vacuum. Seems I was wrong. I haven't found this information for VFR, but for cars MAP idle voltage usually about 0.5V. That's why I thought I may be having problem with MAP.
Ugh.. So many errors in these manuals. They should add a version, so people can understand which one is latest. Ok, maximum makes sense in context of code 2.
Yes, I had no faults before and no faults with replaced sensor as well. If 1.95V is correct voltage at idle - seems there is no issue with MAP and vacuum hoses.
Hmm.. Starter valve sync was made long time ago. Probably it's good reason to do it now. I didn't bother with it because bike starts as usual and idle is smooth. VAX operates properly - 2k rpm on cold, lowering to about 1k after 52C.
How often injectors needs to be cleaned? Is there best practice? I'm asking, because somebody told me that he never seen problems with injectors on VFR and there is no need for cleaning.
Spark plugs was replaced about 30k km ago I think. May be less. I have iridium spark plugs, they usually work up to 100k km. So, I'll take a look at them.
Not sure it is very accurate, probably ordered on aliexpress. So, this means all vacuum hoses is ok.
You mean VTEC ? Yes, it turns on at 6800 rpm and bike goes supersonic 🙂 My personal feeling is that it goes better after 5k rpm, closer to 6k, so no VTEC yet. Very often I ride in traffic, usually on 2nd gear at 2-3k rpm and I have feeling that it don't have enough power, similar to when I had ZZR400 and tried to open throttle on 5th gear - it accelerates, but it feels like it doesn't want to go faster 🙂 It's hard to explain. Everything looks normal, I even checked fuel pressure - also normal. But still have feeling that something doesn't work right.
So, anyway, thank You very much for all information - now I have a list of what to check.
