Changed the air-filter on mine at the weekend. I was recommended (by the dealer) to use an air-filter treatment, about $7 a bottle, which was like thick gloop. I followed the instructions, but 24 hours later had to dismantle the bike to strip down the carbs to remove this gloop from them. Has anybody else had this? Could it be that I didn't follow the instructions properly? Was this God's way of telling me I shouldn't go to Oran Park on Sunday, but should instead spend the weekend rebuilding my carbs? Was I had? Incidently, I hung the air filter up in the workshop (I may torture it later), and 4 days later it is still dripping thick wads of gloop.
