And... why does my flasher not have a home? Doesn't matter it can just hang, but I'm curious.


I was just taking apart my K5 a couple hours ago, the flasher hangs on a weld on tab on the back of the battery box, not on the side with the rest of the electrics.  Its pretty hard to see or get at it with the battery box installed in the frame and the inner fender in place.
If it works good, it looks good...

That explains why the flasher fits in there so well, lol.  Yup, I see the tab too.  Since the suspension is unobtainium, I will have to rig something to hold it up there instead of bouncing around.

For anyone feeling bad about how long their project has taken, take a look at the date on this bag of hardware:

So it was 13 deg F this morning. Heaters making it comfortable for the flesh, still had to go in to warm up the tootsies, but the hardware was stonecold. So we warmed up the cases with the heat gun. Got it warm to the touch in not too long time.

Warmed up the gasgacinch with a pan of water. Stayed away from the heat as its flammable.
Installed the shift drum and forks. The center fork is always a thinker, I know many here have asked how to know how it goes. Besides the pictures in the manual which were pretty good, I realized a good sight from the side will help. Put the fork in one way, and it won't line up with where the main shaft will be:

Put it in the other way and its obviously in line with the line bore for the mainshaft.

I've read here that the someone actually got the cases to close with the fork upside down, is that possible?
Beautiful chains


Last look at the upper case:

Lower case:


Closed up, torques down on the Dynoman studs to 110% of highest stock spec.
Next week, maybe we'll get the bottom end in the frame, and set up the cylinders.

Hey Ron..

Two things: can't remember..but are you dynamically balancing all the reciprocating parts on the engine (i.e. crank, rods, pistons..et al.)?  With all the work you're putting into the engine..was just wondering bout that.

Second: something I found..kinda by default by working in cold shop w/cement floors in winter..has been to put heat mat on the floor immediately where you're standing (the ones they use in green houses..to germinate seeds ..etc.).

I had some lying around here..decided to plug-in..see if it keeps the concrete from sucking all the heat out of feet (they only get up to about 65 - 75 F).  Anyway..thought I'd mention..as it gives little more comfortable working conditions in really cold weather.

Its been a while since I had it done, its been laying under cover for ...er... a year+, but the crank is an "APE RaceCrank" balanced and lightened to their specs. The rods are the APE/Crower rods they had made for a SOHC/4 Group Buy, guaranteed to 400hp, I wish. In line 4s don't need to have the rods and pistons dynamically balanced, but to each other. APE did the rods, and my cylinder machinist did the pistons, which are ARIAS forged items. 67mm = 888cc.

I'll look into some floor mats, thanks.

In a way I am jealous.  I am about done with momma's bike, not much left to do.  Yours, you always seem to have something to do - at least for a while longer anyway.  Hope that made sense.

Judging form your avatar, I'm not sure how i feel about you watching me.   ;)

A lot of people get their builds done a lot quicker and so don't show so many individual steps. Me and build buddy Bruce have lives and businesses to run, so we haven't ever had a bunch of long days, which would speed things up. But we've kept to a routine of every Sunday morning, with some filler thru the week, chasing parts etc. And we may actually finish this year. (Memorial Day is target)

After that, I've got other skeletons in my shop that need fleshing out.

11 deg F- real cold snap, January in IN. Heaters got it to 50, but it takes some of the fun out of it.

Amazing how much time it takes to get reaquainted with things I've done many times in the distant past, but none recently. So we got the oil pump in and the oil pan. Cleaned some hardware, torqued some bolts, futzed around with the shifter, read the manual, oops times up. More to follow for sure.   :(   :)

Not an earthshattering picture, but its all i got.


The bearing holder on the countershaft wouldn't go on all the way. Thinking I don't have the bearing seated all the way down.

I'll start where the last update left off. the countershaft bearing holder would not push up flush to the cases.

The bearing in the holder stands out a little proud. Turns out this is OK. Picture is of a bearing holder from a parts bike, bearing never removed.

So my only thought was that the bearing in the crankcases wasn't seated. If so, that can't be fixed from the outside, so the cases had to come apart.  :(

The bearing appeared to be seated in the cases. Maybe, being new, it was wider than stock...somehow. But that was not true either.

The new bearing has a groove in it but that's just to make it work for more applications. Not material. On that end of the shaft there are 2 gears which must be removed to insert the shaft into the cases, then they are reinstalled on the shaft. The outboard gear is symetrical both sides equal. The 2nd gear in...turns out the offset of the interior is different from one side to the other. I had it in backwards. This is the deep side:

This is the shallow side:

Reassembled and the CS bearing holder snugs up against the cases.
While we're at it, the center shell in the lower case picked up a deep scratch, how I'll never know:

So I'm in need of one brown shell.
While we are at it, i seem to remember someone had an opinion about the primary chains. Should the links be matched side to side like this?

Or offset like this?

or does it matter?

Meantime, I'll order a new shell and ponder where that scratch came from. We removed the crank and looked all around. Any debris would've stuck in the assy lube, its sticky. But nothing.

G'Day Ron, good pick up mate, even if you managed to whack that shaft all the way in, you'd have had gear engagement problems, methinks. Do you use the factory parts manual when you reassemble your engines? I find that it helps enormously! Cheers, Terry. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Don't think i wasn't tempted to wail on it. In fact, i tapped it with a rubber hammer while turning the final drive. But it was obvious nothing was going to give and the cases had to come apart.

Of the 2 gears on the countershaft that have to come off for the countershaft to go in, one was reversible and one wasn't. I reversed the one that wasn't. 50/50 chance of getting it right and never knowing the difference.

BTW, though I've been in these engines many times this is my first full out tranny R&R.

I'm using a Clymer and a Parts Book I got from the dealer where i worked when they converted to microfish. Don't know if the factory book would have alerted me to that or not. A more careful eye on what i was doing would have, or a mock up prior to sealing the cases.

Moving on.

Per HondaMan's book: "Once installed (countershaft) slip the CS bearing holder temporarily into place to...check the gears... In particular, it is easy to accidentally mis-install those 2 large gears backward..." Doh!
