I bought an 86 VFR700 in 2018 with 22kmi on it that had not been running for years. I had the carbs professionally then reinstalled them and started it to make sure I wanted to keep putting money and time into it. It only ran on the back two cylinders, troubleshooting showed it needed two coils. I bought two off of ebay installed them and with new plugs and it has run for over 500 miles in the last few years. For winterization I have drained the tank, use non-ethanol premium, put stabilizer in the gas and run it to make sure it gets in the filter and carbs. I am running K&N filter and Kerker exhausts…oh she snorts so nice! Before/After I’ve driven it more this spring than ever but this weekend it started with less choke than usual trying to be quiet in my subdivision (about 1500 rpm). Within 1 block it stalled. I thought I just reduced the choke too soon so I left it on ½ way and it ran fine at 30 mph. I drove 10 miles going 55-65 then all of a sudden it started bogging down and the throttle wasn’t as responsive as normal. I pulled off the road and it would not idle unless I kept choke on. I was able to turn choke off after riding 1/4mi at 30mph it even idled at a lengthly traffic light. I accelerated on the highway and it soon started bogging again. It seemed like it was pulling normal at full throttle but when I let off it bogged down and wouldn’t idle without at least ½ choke. Next I found a good place to stop and pulled off the side cover and started troubleshooting with no tools. After it had cooled down I idled at ½ choke. I noticed that the front right exhaust was cold so started playing with the coil but had no tools. I removed the spark plug wire from the coil replaced it and pulled spade connectors off to made sure they were making contact. After doing this it idled without choke and the exhaust was hot. I didn’t make it down the road a mile before it started acting up again. I brought it home on trailer and it runs with choke but the front right (#4) is not firing. When I increase throttle sometimes it responds well and other times it bogs. I removed the coil and checked resistance on primary (3.5 ohms) just out of spec? but exactly like the front left coil. The secondary is within spec. When running with plug removed and grounded the plug sparks white not blue. Tested pulse generator and cam pulse generator are within spec. Battery is new and shows 12.67 V. What would you do next?
