well, not even been on the bike a week and picked up a rear puncture. wasn't a flat Tyre, but down about half. was near my riding school, so popped in to see if Brian could help. now funny thing was, when i got the 125, i bought something called slime, in case i got a puncture, never needed it, but as i was off down to Yorkshire last Sunday, i popped it into the backbox. how fortunate was i. so we took valve out, filled tyre with this slime stuff, put valve back in, blew Tyre up to recommended pressure, spun it a few times, then took nail out. was blowing a gale for about 20-30 seconds, then nothing. leak stopped. i've been out on last night, checked it this morning and pressure is fine. it also says it will repair future punctures and is active for 2 years. now it says it is a permanent fix. anyone had any dealings with this.
