what's happening guys we've got a fun day out in the shop here we got some more work to do on the
rm here we're working on the brakes hopefully get them back on the bike and then also we've
got a power sport show coming up so should be a lot of fun where we left off in the last video we
got the front brakes all apart we are testing some different master cylinders on the rear
trying to get that sorted out and so where i'm going to pick up here is i'm going to start
working on the rear brakes we're going to use just a stock rm caliper here so i got to take
that apart clean it up and get all this stuff ready to coat i'm going to pull up the brake line
and we're just going to go straight to using compressed air on this
it's basically just pressurizing the caliper and pushing the piston out
that was pretty painless i was kind of hoping for a big
pop there but didn't really do it got a couple seals inside the caliper
all right caliper is bare next up just gotta
clean up these parts i'm just gonna be using a little bit of simple green degreaser here
oh look what just came in the mail
we have got an air box for the 250 i actually found this off of
a facebook page that i started it's called moto builders guy posted this up and scored an air box
looks like it's in pretty good shape so the one i bought actually off of rm125 looks like
it's pretty much the same i just got to swap the air boot over see how it fits up on the subframe
holes line up so if you guys are looking for an air box like i was the rm125 air box will
actually work on a 250 you just got to swap the air boot over and also that facebook page
really came in handy if you guys want to join it i will have the link down below in the description
pretty much just a page for all of you guys are into building dirt bikes like this also
have some uh first sale and wanted ads on there too so find a deal like this one gotta
give a shout out to reese who hooked me up with this air box he really uh saved my bake
and i couldn't find one i've been looking for probably i don't know six months on ebay and
came across this one and uh he gave me a good deal on it so thank you reese so these are all
the parts i will be coating today just gotta drop them off in the blast cabinet actually there's
some scrapes on this caliper here i'm gonna smooth those out
like to get a little carried away here smooth out all the casting marks on top of the caliper
just use a 80 and 180 grit flap wheel for this and all we got left is to sandblast it
i'm just going to mask off this one area here so i'm not blasting inside the caliper though
now we're on to the coating process this is basically going to consist of
dropping everything into an acetone
soak for about 30 minutes put them in the oven for pre-bake and then just spraying them out
so while those parts are in the oven for curing we're going to work
on this master cylinder trying to swap this over so last video we tried the crf master cylinder
and it fit fine on there but it wasn't quite lined up with the brake pedal so i ended up picking up
a rear master from a 2006 yz250f the hole should be the same so we're just going to see
if this lines up any better with the brake pedal looks like it lines up with the frame perfectly
pop on the brake pedal see how this lines up
so it looks like the master lines up pretty good this way but it's still pretty far off
we'd have to bend it over like that and have the pedal way down also looks like the master
is quite a bit taller up here i'm gonna put the subframe on see if that interferes with it
yeah we're getting pretty close right there it's basically hitting the master cylinder cap so
probably not the best move to use the yz master on here so i did a bunch of research and these
are really my only options here none of the kx or other yz or newer rm master cylinders work because
they have a shorter distance here for the mounting holes and i have to cut up the frame and fab it up
and stuff so i think i'm just going to go with the crf master cylinder and just do a custom clevis to
try to line it up with that pedal a little better get the crf master bolted back up on here and
see what we need to do to make it work i think the crf master looks better on here anyways and
only makes sense to use it because i'm using crf front brakes as well so we're really not that far
off this way it seems to be pretty straight on it's mostly just from the back it's bent
out a little bit so when we redo the clevis we are just going to need to bring it a little further in
and might as well make this perfect too it needs to come to the right a little bit and as far as
height goes it's usually a good rule of thumb to have your pedal in the same plane as the foot peg
that's pretty good right there but we're kind of maxed out on the threads here so if we make
this just the hair longer we're gonna get mr cat over here behind the camera and get a cad drawing
done for a new aluminum clevis all right so nick's been working his magic here in the design software
got the clevis all mocked up there show them how this works a little bit so basically you're going
to want to select um a sketch and select a view and then just uh kind of just draw it out and
then extrude it from there basically you can bring your 3d dimension over to a drawing and make it 2d
then you can put a top view a side view and a front view and just add your dimensions in there
kind of specify you know what the manufacturer wants material and units-wise but yeah
here's the pin that's going along with that here's the drawing for the pin yeah it should be dialed
yeah it looks pretty good we're gonna set it off to machining and as soon as we get it we'll see
how it works so all the cerakote work is done stuff turned out pretty good we did burnt bronze
on the calipers and black on the carrier lever caps turned out pretty good and we're just gonna
pop some seals in it we'll be good to go all right we got the show coming up tomorrow
morning so we're just gonna prep some of the bikes load everything up we've got josh's 500
gonna bring the 250 as well as the rm and of course the old kx engine still haven't figured
out what year that thing is but we'll have that thing set up and uh ready for you guys to build
but for some reason the front brakes on the 500 need to be bled so we're going to get these things
all dialed in so this little guy just goes on to bleeder and you loosen it
up and it's got a one-way valve in here and so basically you just pump the lever
up top and it'll bleed it out see all that air coming out of there a little bit better
still pretty spongy yeah that should be good right there
a couple more things we got to do here this aluminum tank has a
couple fingerprints whatnot so just going to re-brush it real quick
get back that nice green look to it looks like i got a little cleanup here on the
cylinder freaking josh brings his bike over here all broken down guess that's what happens when
you leave your bike at the house can't help but sit here and work on it new bike in a can
all right 500 is good to go
oh man big girl
got a little bit of cleaning up to do on the cr as well had the number plate off of it
and it's just a little dusty from sitting around
all right folks let's get all set up first thing we got is to go
barbecue might as well be eating good all right we ain't messing around got the heavy lifting
gotta have that beauty up front and center right there
all right here's the setup
got the engine this is going to be fun we have a little stunt
show here on harley that'll be fun to watch well yeah should be a good day
a little bit of wiggling get you into place just kind of look at that there yep
and drop slide it right over the pin
cap on top
yeah 15 minutes though it's been a half an hour it feels like it huh yeah no pressure no pressure
it's coming down to the wire it's coming down this right there
there we go
one part left oh we're getting close this way let's keep rotating it there we go
got it all right 14 minutes oh i did it with your help that was good thank you that'll work
cool thank you awesome appreciate it yeah that was fun you're welcome fun to watch
are you gonna do it you're gonna do it oh she was watching the whole time all right
i'm gonna need help taking it apart but i think i know how to put it back together okay you ready
nice good job hold off nice and straight perfect good job
there you go
all right ready to go back together yeah remember how it goes yep okay
is it in yep awesome good job is that as far as it's gonna go uh-huh
give it a little wiggle flip it around a little bit we got look where your time is 13 minutes wait
so i beat the other guy 14 minutes be in my 20 seconds good job nice i'm putting together there
we go thank you was that easier than you thought or harder uh it was actually a lot easier than i
thought because my dad i i was expecting some help on how to put together an idiot he's like it's
like legos just go do it exactly like a puzzle piece you did it awesome good job that's cool
should have been 14 minutes it goes right into that one gotcha going real slow going down
we're going we're going here we go one more shot
all right you got it that's it 7 30. how much 7 30.
seven minutes that was good that was a real thank you
getting excited nice and slow
good job nice
7 40. nice job killed it eight minutes 7 40. these ones are pretty sweet yeah sweet all right yeah
man yeah that's fun too well the show was a ton of fun the engine build idea was a big hit people
really loved it they love seeing how an engine goes together and what it looked like inside and
just curious if i were to throw some local events here in the spokane coeur d'alene area would you
guys be interested in coming out just drop me a comment down below so another thing we're
working on here with rm is a resale for the front end we're going to do a different front fender
and number plate this is off of a 2018 and newer rmz 450 i believe so we're going to mount it up
see how it fits up on there i wasn't sure if i was going to like that style or not but
it's pretty aggressive we'll see how it looks on the bike we've got a cycle stadium
plate love the look of those let's bolt it up looks like the rear holes line up just fine
so the front holes obviously don't line up the rmz triple clamps are a little different
here so probably have to just redrill the fender see how this number plate fits on here
so it uses a little different style mounting holes up on the top right on the triple clamp here
so we should be able to just make a bracket for that should be pretty easy to do other than that
looks pretty good i don't see why that wouldn't work just a little bit of fab work and
be dialed also i'm going to check to see make sure the fender clears the radiators in the pipe
oh dude look how tight that is
let me get it actually hard mounted on there it goes something like that
will be good for clearance here on the pipe clears it by like half an inch this radiator is all
twisted to [ __ ] but we'll get a pretty good idea
oh yeah we got plenty of room there so for the number plate bracket i think we're gonna
have to do something like a kind of like a v shape here so let's get to measuring
now for the fender we're going to do a little aluminum template like we have here for the crs
basically just going to snap into place and you'll be able to drill right through the
holes there makes it super easy but we have a different triple clamp we're just going
to measure up the mounting holes here and use that for a reference for our template
so nick these are your dimensions how about it all right i think that is basically gonna be it
for uh today's outing in the shop got quite a bit done with the coatings and the brakes and
doing some custom stuff on the rm what's a lot of fun about this stuff is nothing just bolts
straight on it's a lot of customization you know with the clevis and the restyle stuff so
makes a lot of fun but the progress is a little slow when you're customizing stuff but i think
in the next video we'll get going again and bolt these brakes together and get them on the bike so
should be a lot of fun and you also see what we have in store for these master cylinders too
so stay tuned for the next video i'll see you in there thanks for watching guys
you
