September 6, 20205 yr Hi. Got a problem with the valve in my Evo fuel cap and it would help if I could dismantle it to sort out the problem. Has anyone ever pulled one apart eg removed plastic housing that holds the valve. Don’t want to go forcing it loose and end up knackering it.
September 10, 20205 yr My 2012 puffs out fuel and excess air. It was driving me mad with fuel burping out. I even made an extended vent hose to get it lower and away from me. Yesterday I bought a new cap! They ain’t cheap. £25!!! I will find out if it works any better. If no different then you can have my old one to experiment with/pull apart?
September 10, 20205 yr Author Pindie Thanks for your kind offer but Ive sorted it now. The problems I had were exactly the same as you have. I carefully heated up the cap with a hot air blower and spent some time going around the plastic insert with a screwdriver until it came out. Then I had to dismantle the valve itself which was a bit of a fiddle comprising of two small springs and rubber seals. After reassembly all seems fine so far. I can see your from South East Wales just up the road from me in West South Wales. You must have ridden with us at Vale Of Towy at some time.
September 10, 20205 yr Good to hear you sorted it. You have more patience than me!!! We should hook up over the winter. The trials bikes a secondary beast for me mostly. Enduro is my main focus but after lockdown I’m to fat and slow to race at the moment. It’s good to be back on the trials iron refinding skills. Not been down Vale of Towy but always up for some riding.
September 13, 20205 yr It’s sorted. Three hours riding woods/slopes yesterday and no fuel came out the breather. It was a £25 fix but easy just swapping caps.
