I've not been using the bike much at all this year until lately and when on a rare reccy I kept smelling neat fuel. I checked the main feed hoses from petcock to carbs and found a very small hole/tear near the end of one hose at the carb end, removed, cut off a few mil' then refitted and all was well but I kept thinking it might be time to replace them to be on the safe side. What a mistake that turned out to be as I now have a fair size leak from one side at the T join so have ordered two O ring sets...the replacement fuel hose was a tight fit so even after softening guess the force required to push fully on has disturbed/broke an O ring, or two . Sometimes I really wonder!! :bonk:I've read some old posts and it seems running the engine first to introduce heat will help when removing (fighting) the carb bank from the insulators, I realise all cables need to be removed etc. but what else should I be aware of? anybody replace these damn O rings that might offer some guidance?
