Help if possible around the North Shore?

[jaymzw]

My CBR250r is leaking fuel at the moment. I have been told it is quite noticeable to smell

Im relatively noob with engines and have had a look etc but i am constantly at a disadvantage as i cant smell (born with a cleft and apparently that did it) so really cant find anything using smell and petrol and oil arnt that nice to eat ;). I have previously stripped the fairings off the bike and left it running but i cant find the "source" as such.

Any help would be appreciated. This is a last resort before taking the bike to the shop and spending my own moolah...

Thanks in advance guys

Nah no pool just can see where it is on the bike. And apparently smell it which worries me abit

[FROSTY]

so WHERE is the fuel on the bike?

This would be best listed where the majority of the mechanics minds are found, in the maintenance forum or the like but here is my helpful tip.

There are only so many place fuel can leak from on a bike, start at the fuel tank and check for any fuel residue on the tank itself. Find the hose from the bottom of the tank and follow it down to the engine checking for any leaks as you go. The only other place is the carburetor (place where the air and fuel meet before they go bang)

Its just a matter of checking where the fuel is and looking for the very tiny leak somewhere along that fuel line.

Hope this is helpful.

Its on the left hand side just under the frame. While replying ive started to think possibly the fuel tap seal??? Is that possible? Im going to have a look anyway.

I think i started backward then.

Looked at Carb first then tank.

It doesnt matter where you start as long as you know where to look for the fuel is the main thing. At least if you start at the bottom you can follow the trail of fuel up the line and then find the leak point.

It could be possible, the fuel line could be eaten out or the seal in the fuel petcock as you guessed. Use a clean rag to wipe away the fuel to see if it is leaking from that point.

Thanks Chris but i think its the seal on the fuel tap. I draind the tank and then removed the seal and tightened the bolts back up. No more leak. It looks like petrol must have eaten into the seal over the last 19 years. Anyone know where i can get one of these as i dont think this is a long term fix :oi-grr:
