Bad R/R The symptoms are definitely bad R/R. Your new one was bad from the get-go, or it fried already. It isn't regulating at all. What year is...
I remember a long time ago Suzuki had a stator overheat problem and part of the dealer fix was to drill out an oil hole for more cooling oil spray...
I don't run slicks. These are street legal, DOT tires with treads and arrows showing which way is forward. Track days take rubber off the sides...
I mix tires. VFR has a Dunlop Sportmax GP-A on front and Michelin Pilot on back. I like the combo. Neutral and stable. No chicken strips at either...
Something that helped me is dirt riding. At first I panicked whenever I saw dirt on the road or felt the bike squirm a bit in slippery conditions....
Your regulator failed the same way mine did, allowing the voltage to go way above 14 volts. Mine went over 36 volts, the maximum my voltmeter...
I've always had sporty bikes, but last year I got a deal on a well-kept 98 Magna. I've become fond of the old gal. She sounds mean, outruns any...
That's an amazing project. I'd have burned out long before the car was drivable. Wish I'd seen the thread 6 months ago. I could have used a few of...
I put a cheap Chinese MOSFET R/R on my 5th gen VFR a couple of months ago and so far, so good. It runs a lot cooler than the Honda part and...
The jets determine mixture at full throttle and the needles & shims control mixture at part throttle. So if it's too rich and fouling plugs...
Here's an explanation of EFI systems, open and closed loop. http://www.bikeboy.org/open_closed_loop_efi.html The very definition of closed loop...
As everybody else has told you, closed loop operation is IMPOSSIBLE without a working, REAL, O2 sensor. Period. That's what closed loop mode...
I have a 5th gen VFR with aftermarket undertail dual exhaust. Short story, everything back of the gas tank gets modified or replaced. It can be...
Coolant temp will bottom out at the thermostat's opening temperature, 175-180F on most Hondas, at high speed with a lot of airflow. If your temp...
Have you checked sag? If your bike feels like no suspension, chances are you're riding near either the top or bottom of wheel travel. You want the...
I can't speak directly to your year VFR, but my 2001 does vary somewhat in operating temperature, and it seems to be common among the later VFRs...
OK, today I installed the MOSFET R/R. It is not a Shindengen part. Mfr unknown, but "Made in China". That's why it's under $30. It's claimed to be...
Rather than current, there is another limit, how quickly the FET or SCR or whatever the switching device is can be turned off. It has to respond...
There is a pointer to the 5th gen Honda shop manual for download someplace around here. I found it when I bought mine a couple months ago....
