2004 Plastics allow for easier air filter access, plus the orange does look good. :thumb:

No 2002 replacements available without waiting a lifetime for them and as PA said, they look trick and easy access to the airfilter.

I've got carb issues now. Left the fuel on last night (that will teach me) and it pretty well drained the fresh liter I added yesterday all over the garage floor :(

Gave it a few kicks and it's pissing fuel out the exhaust joint.. Thinking the needle and seat are shagged?!? Any other reason it would poor through the carb like that? #-o

that's the Mikuni carb...happened to me years ago with an 02...you'll never forgot to turn it off now

in my case, I had to turn it (the bike) upside down with the spark plug out and pump the fuel out that had made its way into the crankcase

Can upgrade that model Rev with a flatslide carby...makes a huge difference and no more issues with losing litres of fuel

Really?? I struggle to get my head around "it just leaks" Nothing can be done at all??

Do you know any more info on the flatslide upgrade?

Cheers

Have a look here (http://www.trialscentral.com/forums/top ... kuni-carb/) for more info on what needs to be done. It's a few pages long and has a few different suggestions for fixing the problem.

Also, call David Ryan from Beta in Melbourne, he will be able to help you.

the fuel tap needs to be off regardless of what carb is fitted...its just that the Mikuni when fitted to the Rev3 seems particularly prone to leaking overnight....

Digging up an old thread, sorry..
I've just run into some more carb issues with the REV3 and it's got me stumped... Last ride the bike was perfect. Cleaned, put away for 2-3 weeks and when I got it out last Monday for some reason it was 'running on' bad. Not really sure how else to explain it. I have some video uploading at the minute, will post here as it may help diagnose. Straight away the bike didn't sound right, when left to idle would gradually wind down and stall.

Between rides I changed out the leaky fuel tap in the tank. The old one (and tank) were full of crap. Flushed it all out and cleaned the fuel filter with petrol. The only thing I can think of is possibly some of this has made it into the carb?

Any help getting this sorted would be much appreciated.

Cheers
Craig.

If there is crud in the tank and fuel filter then you can pretty well much 100% guarantee that some of that crappola is in your carb as well.
