get a battery! check fuses by removing and cleaning the glass fuses. no power as such across the points its a ground for the coils.

what's the question again?

have you put the O rings back the correct way? mikexs describes the way they go in in the advert for bs34 carbs

I would dsay its an earthing issue, check all black wires from the signals and clean frame around them.

presumably its an xs400! the carbs need a really good clean, ie strip and all the orifcies clear, use berrymans or seafoam and blow through with air.

here's a scan

wait till you see the rest of the bike.... anyway

in weakens the mix! the slow to return to idle usually means its weak. If when it is warm, what is the response like then?

cheers fellas

cheers Merv

if you have sight of your parts and they look the same, i would get them. on part #48-5012 I would look at a new needle kit instead/as well, as I'm sure it wil be worn.

so its back to a yam now? Bar-stewards, obviuosly done to order, probably for parts!

that is a brass plug, take it out by self tapping screw and yank on it. under neath that's where the pilot screw is. That version will have an O ring which will almost certainly have perished. Mikes XS have spares. know the manual says 32mm but if you have brass floats, they are best @ 26mm

to the forum. Fairly rare bikes , so keep an eye out for sapres in fleebay

i used to live in Combe Martin!

:lol:

OG has asked me to post this as he has become anonymous wearing his. i think he is having a Reginal Perrin moment click the piccy if you feel the need to buy one.

leave the needle valves for later, its only for the top end. pilot mix screw 3 to 3.5 turns from bottoming out

nice work Paul hope to see ya at the YOC meet

best O luck Mervin!

excellent vid BWJ

this cat must be really addicted to the dreaded weed

the xs400 carbs need a real good clean as they are old and finicky buggers. try unscewing the pilot mix screw 3.5 turns from bottom, this seems to offset the shite liquid which passes for fuel today! by carb clean I mean stripped down, everything spotless. does look like it has rust in the carbs before the filter fit?, also the float hight needs checking (26mm top of float to under bowl gasket)
