Over at the last RR I posted, I believe I mention a friend who had a
bike that we tried to fix for the ride without success. Well, last
night we finished diagnosing, after removing head, clutch cover and
magneto cover: Stuck connecting rod, worn out crank bearings. btw, it
is a Honda 350cc with RFVC engine, never mind the bike, jftr, it has e-
start <g>. Poor guy, he replaced piston, valves, cam chain, one rocker
arm, cam chain sprockets, the cam chain guides and tensioner, clutch,
starter clutch, starter motor brushes, automatic decompressor
system... That comes to prove my theory: completely rebuilding the top
end of an old bike always will cause failure of the bottom end within
a year.
It is the second case split I do at home this year. I am getting good
on this, but I hope that on my own bike the case split be years from
today :-)

This probably looks familiar to you then:

Right now I'm waiting on an OEM countershaft seal since the
aftermarket one (part of a gasket/seal kit) was junk. I didn't like
the thought of splitting the cases again next year just to do the
countershaft seal.
Fun, isn't it?

yes, it looks... <g>
friday afternoon (*), about 3pm
I was cleaning the carburetor and the starter motor while two friends,
friend 1 the owner of the bike and friend 2 owns the bike that we
split cases earlier this year.
friend 1: finally it is back together. Let's put all the screws back
and close the cases and start mounting the cylinder and rest of engine
friend 2: isn't better we test if all the gears are engaging
correctly?
friend 1: nah, we did not disassemble the gearbox, so it should be ok.
friend 2: if you say so, ok, please, reach the #5 allen for me please?
fast forward to saturday, 5pm, after putting engine back into frame,
clutch cable in, oil in, carburetor in, starter motor in, only missing
the exhaust to be able to fire it up.
friend 1: hey, could you put this thing in neutral so I could push it
a little so it would free some space in the front for me to put the
exhaust?
friend 2: uhhh, this gear shaft is weird
friend 1: oh, no!!!!!
the return spring is not correctly positioned, to fix, we'll have to
split the engine again. I spent the best part of sunday disassembling,
but his bike has some #4 allen bolts and seems that friend 1 put my
allen #4 together with his allen wrenches, therefore the clutch cover
is still in place. I hope to get in touch with friend 1 today, ask
friend 2 to come by my house tonight and finish splitting <again> the
cases, reposition the spring and start putting it back together, so we
could go for the holiday next friday at Tamandare beach towing the
bikes and have a good time exploring the trails around Tamandare city.
Bike must be ready until tomorrow, because wednesday I have spanish
language class and I can't miss it. Spanish is much more difficult
than I ever dreamed of. Granted, it is easier than portuguese, but
still, much much much more difficult than english, imo.

good thing that the 350 has the seal that could be removed from
outside. This particular bike we are fixing has this seal bad and,
like you, back ordered, but it is leaking so little and it is a two
minute job to replace that we'll start the engine - and go riding -
like this.

yeah, I can tell that!
(*) friday afternoon I was supposed to be at work, but friday, 7am, a
woman on a Pajero TR4 jeep (http://files.windingroad.com/newsuploads/
2007/06/mitsubishi-pajero-tr4-lg.jpg) stopped in the middle of the
roundabout and I rear ended. Her: broken bumper. Me: hood, radiator,
grill, headlight, blinker, bumper.... complete front end. To fix my
car: $500. To fix her car: $2000. Coincidence or not, I found out she
lives in the same street I live and she is one if the best customers
of my employer.... And, this is only one week after a ruptured
radiator hose lead to massive head damage and a $400 bill to partially
fix the engine and make it "runnable", because I could not even dream
in afford the $1300 that would cost to properly fix it.

idea how to convert it **

When I arrived from work yesterday friend 1 & 2 were in front of my
house waiting for me. We were able to start the engine, but the
automatic decompressor thingy is making a clattering noise. If you
don't fix it until thursday night, we'll remove it. It has e-start, it
doesn't need the decompressor at all.
We are becoming good at this. Split cases, repositioned spring and
reassembled and started engine, counting disassembling reassembling
the decompressor system twice (removing cam, cam chain, rockers, etc)
in only five hours.
