4-12-2016 XB12 1 cylinder, XB winter service

16-12-2016 - Buell XB12 running on 1 cylinder, Buell XB12 in for winter service

nice Xb12... but she is running rough.. and drops out on 1 cylinder

ok top off and check below deck

as it sound like the fuel is starving out.. i put the fuel perssure tester on , but pressure is good and holding

i will have a look at the iac

not much sooth on there

i cycle it in fully open and mount it back, it will set it self after you turn on the ignition

did a leak test... intake seals are leaking ... the one screw you cannot get to right side airscoop

i remove the pully cover as we are going to drop the engine

left scoop off and w.brace loose

left foot peg plate off , this will damage the primairy cover if tyou leave it on

and disconnect the crank positioning sensor and side stand connector ( if you have one )

clutch cable needs to come out off the handle, with aftermarket levers sometime you cannot unhook theme, just unscrew the lever to get the cabe end out

struggle with the one screw..

and support the weight off the engine, micron mufler plenty strong

with the weight off you can remove the center bolt

throttle cables need to come loose

08-up models easy to remove the coil

to have better acces to the nuts on the throttle cables

unhool the cables

and loosen the bolts, 08-up are hex bolts bought sides

mnnn ok there we have the problem... the side support screw dropped out... the intake manifold moves to much like this.. no way the seals are going to hold this

old out,

new in... i find it easier 08-up to put the bolts in later, as the big flanges need to move around during mounting

and side support screw in !

engine back up.. set mount bolt to 66 Nm

mounting the w-brace... take the screw... doing it so much.. i pick theme blind folded

hooking in the throttle cables push the barrel in the hole and turn the cable , works for be best

on the 08-up i first put back on the cables on the grip

and make sure there is enough cable adjustment left

than set the positon off the throttle cables as this is set with 2 jam nuts so realy flexible

coil back on

the coil wires are hold on the throttle bracket with a cable holder

connectors on

and time to test... running good 

so airfilter back on

fuel breather hose.. behind the left footpeg there is a plastic eye you can route it trough

pully cover back on and chinspoiler tight again... ready

winter service for this XB

still looks very nice the 200 rear tire :-)

primary tension is way to tight...

drain the oils new o-rings and some hydrolic loctite

as there is high performance clutch in this bike, ATF D4 is use for the gearbox oil

and setting the primairy tension

exhaust off, as we noticed the intake seals are leaking

i take these brackerts off, less hassle than the band clamps on the termi

suppert the weight off the engine and remove the bolts

almost the same as the 08-up..

except these are non bolted cables

connectors loose to remove the manifold

this screw is still on ;-)

front spark plug wire has been rubbing as it was turned out

best to turn theme inward

manifold loose, mnnn

little signs off leaking

the rubber is hard on the edge

and t has formed a edge

i think blue seals are better in this case ( there thicker )

they need to fit good.. other wise this is no improvement

if you need to jam the manifold in between the heads because off the blue seals... not good, should mount easy and bolts should go in by hand

if you need to jam the manifold in between the heads because off the blue seals... not good, should mount easy and bolts should go in by hand

will repace the front cable as i see more rubbing markings

engine back up and bolt to 66 nm

exhaust back on.. i use a little red loctite on these hanger bolts

throttle was hanging a little... the idle wire is nackered and prevents the cables to run smoothly
