KR-1S.co.uk Forum

hi their .. im very new here as you can see this is my first post ..

neway im rebuilding a KR1S from the ground up . i bought it 2 years ago it was 2 wheels and a frame and slowly it has came togeather i have even managed to get her running but im having a fuel problem .. this is my first project and have worked on a few bikes but this has me stumped .

so here goes . i dont understand the fuel lines on the carbs .. the manual is pants i need to know were all the fuel lines come from and go to ?

sorry if its so simple a monkey could figure it out but im no that sharp .

oh and if you feel like throwing in a picture that would be handy ..

thanks for any help you can give .

all the fuel lines connect to the tap on the tank

the main ones off each carb connect to the lines either side of the
tap (doesn''t matter which way you connect them)

on the l/h carb there is a thin pipe which connects to a protrusion
on the top in front of the main body - this connects to the small
protrusion at the bottom of the tap

hope it's clear

ahhhh this is the little buggar that i missed thanks very much for a fast and helpfull response .

thanks.

the small pipe going from the (? left inlet rubber to the fuel tap dighfram) is just to open the diaghfram in the tap ,it causes a vacume to let fuel flow,(japanese safety feature) just a tip i picked up ,i start mine on prime on the fuel tap ,starts first time unless not used for more than 3 days,and if your out for a thrash about i run on prime as well,i heard some lads racing at mallory park had fuel starvation problems running the tap in the normal position
