Once again, thanks for hints on backfiring. bike running great I just changed my oil after the ride and thought i'd check on here for further info and read that some owners are putting 1.7 l of oil in. I have put just over 500ml,( roughly what came out less oil filter small spill) then followed directions of when to check oil( run for 10sec) and it reads up to 30mm over high level on the dipstick. it always reads high and i have preffered to have too much than not enough. Have checked some more threads re quantity, then checked oil level again hot and cold and is still over dipstick high mark. any suggestions? by the way wheres marcus gone? the responses used to be a real kak.
