Over the past month I've been trying to get the 6R up and running to use as my winter hack. It was treated to a new chain and air filter and ran fine for a day or two and then I topped up the oil and 2 problems sprang up. 1. The choke stopped opening fully - it would only open to about 1/3rd of the way. 2. Riding in to work I was right at the end of my 10 mile journey when it felt like the bike was running out of petrol. I stuck it on reserve and it was fine for the last couple of hundred yards to my work. On the way home, however, it suddenly started kangarooing really badly. It was running fine up to 35/40mph and then would just kangaroo and refuse to rev any further. I've had the carbs off, freed the choke and changed the plugs, which has sorted out problem 1, but problem 2 is still there, if maybe slightly better. A quick test this morning shows that it will rev out in 2nd gear, so up to about 80mph, but once you start changing up it won't pull anywhere near enough revs for this speed - it refuses to rev above about 7.5k. Opening the throttle wide makes the problem worse, to such an extent that it actually speeds up as you shut the throttle. The whole thing feels like I remember my original 6R feeling post-bin, when I tried riding it without all of the ram air gubbins, so I'm guessing it's something to do with fuelling, but I can't understand why it would suddenly go from absolutely fine to completely screwed mid-journey. The only other symptoms I have are: 1. When I took the carbs off one corner of my new air filter element was soaked with clean, fresh oil. I'm guessing that I overfilled it slightly and some oil was blown out through the crankcase breather. Running it now doesn't seem to add more oil. 2. One of my dashboard bulbs had gone - the one illuminating the top end of the rev-counter - but not it's working again, but brighter than all of the rest of the dash lights. So, any thoughts on that mishmash ... other than throw the whole thing in a skip, obviously?
