3-5-2017 M2 check up, XB12 broken throttle shaft

15-6-2017 - 3-5-2017 Buell M2 check up and front seals, Buell XB12 broken throttle shaft repair

nice M2 in for check up

bike is 1997 ... only 16000 km done so far

as it had trouble running.. just checking... yep.. i bet the first seals are still in here

but first the wet stuff... engine oil draining slowly

but first the wet stuff... engine oil draining slowly

checlking the primary.. screw heads are almost done.. need to take the lever off

do not pry open these levers they will break very easy ... with a tire iron and some protection force it off

hammer and socket just got it , wil lput new screws on

removing the fuel tank for easy acces to the throttle bodie

aircleaner off

and exhaust off to change the gearbox oil

drain plug gearbox.. above the exhaust

while the primairy is draining.. top side to get the manifold off

throttle cables out

and carb off

the hard to get bolts ( left side ) intake manifold

yep.. first ones.. still on.. looking at theme a wonder the bike even run

heavy deposit on the heads fromt these gaskets

gear box was drained, so first new oil in

checking the primairy chain tension

new bolts for the inspection cover

and fresh oil filter on

checking the plugs.. customer told me he changed theme just.. i wonder why he put in DCPR7 ( 6R12 ) a heat grade not really advised

and for the little they did run the look not good.. i will put in DCPR8 heat grade.. much better

scraping the heads clean

the old seals have dry rot and are cracked all around

with new seals. manifold inplace

carb back on

cleaned the breather and mounting it

broke the choke cable...

so carb off again

and choke cable out the carb

new cable on and screwing it back in

carb mounted again.. and breather bolts.. .i use a light oil sealing loctite as you can not force these bolts... they break way to easy

and choke cable mounted

exhaust back on

rear wheel / belt check... bought ok. but belt is to tight for my lickings

wheel nut loose and adjusting the tension

better , to loose is not good, but to tight is killing

bike swaped around for the front end

wheel nut loose

don't like these covers... hard to see. but bought fork seals are leakings... they are just done by a repair shop ? so what is wrong

old Pm caliper , bolts and pins to get the brake pads out

pins are hold in with cotter pins

wheel out .. bearings are ok.. some rust on the disk from standing still . but that will come off the first km riding

front fork out.. loosen the headlight bracket

dust covers... look like they pinced it inbetween the brace and the front legs , could be a cause the seals are leaking.. pushing out the legs to far

anyway top cap loose

slider down, and remove the holder disk

2 14 mm spanners to remove the damer from the rod

mnnnn o yes could be fun... rounded out damper bolt

pfffff... it would still come loose after a tap to hammer the allen key in

dust seal and clips out

and slide hammer the slider out the lower leg

these are old model, loose bushings no fun to mount

no damage to the legs.. so i think the jamming on off the fork brace is responceble for the leaking seals ... new seals in

damper in

damper bolt with new crush washer

a little fideling to get the bolt and damper in correcly

oil in and top cap on

1 down 1 to go

use new crush rings when you do this.. the old ones are knackered

and leg 2 done .. back on fender on, and i put the dust cover loosly in top , the fork brace fits freely now

mechanical speedo back in the wheel

drop off loctite on the threads

and torqing the caliper bolts

warming up.. still carb needs a little love... as it will not keep a idle off the choke right now ...

uly in with broke throttle shaft

road repair service had a look already...

ok engine needs to rotate.. to ready top side

and start striping the lowers

W-brace loose

exhaust off

engine supported and front mount bolt loose

engine rotated down, and removing the throttle body

bougth screws accounted for

and the shaft is not missing any parts

tps sensor off

2 ways to remove the butterfly plate.. in this case loosen the screw did work.. outer wise we would need to drill the head off to retrieve the butterfly plat

easy cleaning now

all parts acounted for

cleaned and ready to put the new shaft in

nice :-)

c-clip in the tps side

nylon bushings on and put the shaft in

now first put the throttle cam on with spring

than line out the butterfly plate and screw it on with the suplied screws.. use a drop red loctite to secure theme

check your tps sensor.. as we make the throttle shaft for bought tps positions.. you need to put the pin in your self

this old style tps so horizontal pin in

tps sensor on.. press it on a little rotated off, and trun it to the mounting hole ..

looks like the intake seals where leaking to

intake back on

engine back up and bolt to 66 Nm

exhaust back on

will mount the straps the nice way

top side connecting

setting the tps

contact... she is running nice again

will do a small servic e , to , draining the oil

new filter on, and fresh oil in.. just the rear tyre and she is ready
