3-12-2016 XB top end , S1 bigbore custom
15-12-2016 - 3-12-2016 Buell XB top end and Buell S1 bigbore custom
cylinders and pistons are back... time to clear out some parts boxes....
almost sinterklaas :-) i like presents... beying marked means to me some one matched the pistons to the bores al ready for me
:-)
yep... set to match
as always... but theme in the sink with some dishwatter soap..and hot watter to clean the bores... there only clean when you can whipe a clean rag trough theme and the rag stays clean
yeah i know... there matched.. .but still i'm the guy building it... mistakes are to costly in this stage.. so checking the end gap on the rings
perfect spot on in the middle off the range
check the orientation on the pistons
whipe some running in oil in the bores
and with a ring compressor clamp the rings
and push the piston down the cylinder... just the rings in will do as you need the push in the piston pin
new base gaskets
and take the cylinder and push the piston pin through the rod end
piston pin clip in, and push the cylinder down
secure the barrel... you can use the short head bolts for this with the ring or 1/2" socket
next down the barrel
before we mount the heads, the pushrod covers must be mounted
put the pushrod o -rings in the cylinder head
wet the tips off the cover
and push down the head over the pushrod cover... than located it on the dowls
oil on the head bolt flats and a little on the threads
and TQ the heads down
on older bikes really common the markings are gone on the pushrods
als long as you remember the long ones are for the exhaust... you can check the manual for the specific lenght
rocker box back on , all the screws in be fore you tighten theme as there is no tight alinement
and tq the rocker box down
top cover on and breather pipe in, before we for get this
rear one = more the same , but take care off the head temp sensor wire
in the right positon you can almost get to all the bolt in the head
before you close the rocker box... a squirt oil on the valves will help the startup
cover on and breather in
time for the coil and top mount
aline the coil bracket to it sits in the middle
now also the time to mount the startup plugs
will use some fresh plug cables, these are done for
with the engine down... very easy , turn theme in a little so they don't rub the the cable guide
header back on
injector plug on
and engine up... TQ this one to 66 Nm
i want to run this bike in with break in oil.. so i drain the case , as i have easy acces to it now
while draining, mount the rest W-brace
hook up the electics
normal oil in the case is about 0.5 liter
exhaust mounting.. easy to have a lift to take some weight off
tighten the rear straps
front mounting
tap the slide on connection , to release any tension , and tighten the clamp
running wires
take a ziptie and loop this around the oil pressure sensor, to pull in the regulator wires
top side connect
now waiting on delivery off break in oil before first start up
S1 custom project... the custom milled pully was a little to shiny.... painted the center black ...
looks better :-)
front end.. handle bar / risers
we are going to mount a motogadget clamp so we need to have the HD clamp mesurements... and we are going to mount a fat bar... to loose the spacers being used now
nice triple t nut... will clean off the scratches... and make a tool for it ;-)
fabricobbled brake lines... i cut it .. going to replace theme anyway for some custom made ones
trying out the head light brackets
with stock headlight
we want the handle bar lower... and the risers lower... so taking these off
and mill these off about 15 mm
bought milles down and bolt made shorter
better
on the bike
low postion .... mnnn my hart douse not start to glow...i think we are going to try with a different head ligth
preping the case for painting .. looksy at the business end off a knife egde lightened crank in a bigbore case
with some rod that mean business :-)
