Hi all, anyone know this size as standard?

I will measure it this weekend but would like to order some today and I'm not with my bike.

10mm m8..... on the 19L it's 12mm (mine was anyway lol.....
i get mine from http://www.cbsonline.co.uk they sell all the clips and tees as well.

i noticed on mine, when i fitted the 19L tank, i used the old 10mm pipe off the smaller tank with twin outlets.
under hard accel at full throttle i noticed fuel starvation which is why i went to the bigger size... presumably as the one pipe has to feed both carbs.
not had the problem since

Much obliged benny. I have a fuel pump on mine which cures the hesitancy when leant over.

I'll have to check tomorrow.
Cheers

i did the fuel pump mod on mine too and it does improve matters when riding hard....
ive disconnected it atm as im running a filter after the respray and was surprised the problem hasnt returned!

with mine it seemed to be just high speed acceleration at full bore, it would snatch back at me a bit cos of fuel starvation... tried a few different pumps and ended up with a pentax one off a volvo - works great :)

Cool. Roger recommended a pre 99 cbr600.

I learnt the hard way. I was chasing an R6 at brands and even though it was hesitant coming out of the hairpin I gave it some beans after being leant over for a while at clearways. As I started to stand it up fuel poured in and the power came on quicker than I could cope with. Massive spin, loads of smoke and a low side. I learnt a lot about relaxing in a crash at that point. Fuel pump quickly found and fitted.
