Hi, I have a 2004 RSV1000R Factory. Last trip, fuel tank had massive pressure build up. When fuel cap removed, fuel shot into the air. Quiet scary. So, whats causing the pressure & how do I fix it? Otherwise, bike starts & runs normally. Thanks.
Hi, i would say you have a blocked breather. You have two pipes underside of fuel tank one for fuel to breathe and one for water etc to drain. I would check that both are clear. It is quite common for the metal unions(pipe to tank) on underside of tank to fur up and create a blockage. The only real way to cure this is to use a drill bit to carefully clean out the hole so it becomes clear of obstruction. Be careful not to drill off centre!
Hope this helps, Darren.

Is it really that easy?
I think the drain nipple on mine is blocked. I've tried to clear it with compressed air (failed) the I tried some thin wire to clear it (failed)
Do the nipples just unscrew out? And when you screw them back in, is there any sealant needed?
Cheers dude

Always pissin down with rain Sussex
Yeah it's that easy :biggrin
There are two aluminium nipples, when you unscrew them you find the ali has corroded & blocked the holes as their quite small, I opened mine out with a slightly larger drill then nickle plated them to stop this from keep happening as it's a pain in the *** :roll
I didn't bother using sealant as it's only a drain hole but a smear of grease would help stop it corroding

Cheers fella...I'll get on it tonight then ( I think)
Those two aluminium nipples???????.....any connection with your avatar? :lol:
Thanks Darren - you were spot on with your advice. Took it for an MOT Friday, it failed on rear suspension unit (bad oil leak, no damping), play in upper & lower suspension mounts, rear brake not functioning, front brakes advisory, rear tire worn below limit...
Its now in bits with me having to remove the exhaust system to get at one of the suspension mounts on the rear shock - fun & games.
