Bill I posted this in Fuel cooler and due to the age and mileage on the Brick I decided to get a set of brushes. Sometimes it can take time to source and receive parts so it pays to preempt. However I got the regulator in 2 hours, and as I stated they were on their limit of 5mm. Since changing the battery has remained charged but I am still not sure if the battery is 100%. And I don't have time at the moment I suspect a dirty injector with the rough running and misfire.
Extract from Fuel Cooler post.
I went for a short test ride to the shops 2K. Half way there it started to drop one cylinder and run rough and hesitate on acceleration. I did what I had to do quickly, and when I went to start it was reluctant to turn over. The engine ran rough on the way back and cut out twice at the traffic lights and I just managed to get it to fire up, it was reluctant to turn over. Once home and on the stand it would hardly turn over and after two tries would not turn over. At this stage I didn't want the relay to stick so stopped trying, and decided to investigate.
One hose on the cooler had developed a kink so I removed it and blew it through no blockages. Next checked the vacuum line to the FPR looking for fuel, it was fine. Next step removed the spark plugs which were very sooty. Tried the starter and it turned over but not at it's normal vigour. listened for the pump and it was pumping. Put on my spark plug lead test harness and went through the plugs one at a time checking the spark. They were not that strong not that but strong enough to illicit starting. Replaced the plugs with new ones, and tried to start it wouldn't turn over.
Put the brick on charge and before I went to bed, I tried it and it fired right up and ran smooth. This morning I put the multimeter on the bike. The readings as follows static ignition off 12.58v ignition on 12.10v run at idle 11.81 rev to 2500 13.23v. I couldn't really get a reading on the current draw on hitting the starter, it start too easily at a guess about 11.5v. I'm suspecting the battery as it is 5-6 years old but the running rough has got me a bit stumped. It should of run smooth when the alternator cut in. I rang Turbo Batteries to see if I could get a RevPlus AGM battery. The last time they didn't have a Deka which had been my previous battery of choice. Looking on line I could not find the same RevPlus number. The took the bikes information and said as they were busy would ring back later, that was yesterday afternoon it is now the next day.
As I have to work today I'll have to investigate further this afternoon when I finish.
Regards Martin.
