Went out three days ago and did 240 let's say very enjoyable fast miles then today went for a blast in the Peak District however today noticed what is either the bike running on like three cylinders or an issue with the exhaust which is more very black at the end of it after 70/80 miles today and alot louder than normal. Any ideas guys? Only done 900 miles in total
I'm no mechanic but soot often indicates it's running rich but that wouldn't explain it being louder. I would check the exhaust connections are secure and havent worked loose as a first step
