Free bike; engine rebuild!!!!?
04/11/11 at 23:35:46
 
Hey guys, pleased to say my neighbor (we'll call him Dustin to protect honor) scored a free torn apart 1986 Savage from someone who was going to toss it. 33,000km, and everything organizingly dismantled.



However after 8 years of this bike sitting neatly in boxes, it ended up in the back of Dustins truck and later on his driveway where it collected sawdust from his garage. Long story short we were going to part it out but I decided to give it a go and see what I can do for my very first engine job.



Im only at the engine right now.

First thing I did was a mockup assembly, guessing where parts go, just to see if I might be missing something major. Seems to be all there.



I took it apart and cleaned out most of the sawdust and other junk. Bought some Ultra Black just to get a decent oil seal while I dump some oil in it, set the valves, and check for compression.



I basically finished it up, with a few leftover parts Lips Sealed



Now I better ask some questions...


1) I used regular gasket paper + Ultra Black for the head gasket, was told it wont hold up, but for research purposes Im going to try it.

2) How can I crank the started directly off a batter/charger? Dont feel like mounting it into the bike or hand cranking with a socket anymore.

3) when setting the timing chain, I marked the white line on the flywheel at the 3 o'clock position through the cap checker thing for TDC. Then I lined up the cam markings with the block, lobes facing down, and mounted the chain, secured everything, dabs of grease and oil everywhere. Attempted to set the valves, everything seems to be functioning smoothly. Did I do this properly?

4) Can anyone Identify these extra parts Cheesy

You need a new cam chain, that one is pretty stretched.  if that plunger falls out you'll be looking for a shovel and a trash can.

Yeah, paper and rtv won't last long on the head.  probably better off reusing the old one.

There's a bolt sticking out of the starter, that's positive.
If it stalls, rotate the crank a half turn forward past compression TDC then go at it again.

L to R
a spacer, an o-ring, a bolt, a bolt, and a pin.

all of them can go any where you see a hole.

The pin goes in the center of the clutch.

Hey, I'm not complaining, you got it free and it lives.   Smiley

I havent been thru every nook & crannie on the bike, buy Im not really thinking the spacer & O ring are part of the bike. Yea, that sre looks like the clutch throwout pin,,& the bolts,, well, Id be looking up top of the engine for the long one, short one?? No clue.

Congrats on getting this far.

Looks like the previous owner was familiar with the cam chain tensioner weaknesses and made his own verslavy.

you did very well considering all you had was a box of parts to start with.
as far as the cam chain, how about a safety wire to keep it from falling out, at least just for demo purposes.

That was me, Im assuming thats why he tore it apart is because of a rattle. I had known about this issue from this forum with a previous bike I had visited with.

Assuming all the Gasket maker has cured this morning, gunna torque everything up and run some oil through it, crank it over, get soome of  that sawdust moving, see if we get compression.

I'll have to look to see again, but think 10 is flat and 11 is beveled.

the 4 bolts should be tightened all the way down.

alright, im leaving the clutch out until further notice.

Just mounted the engine, connected all the wires, and put a batter charger on the positive battery wire + grounded. all the lights come on and everything works, until you put the right hand engine switch to "Run", then I get a constant, loud, arch between the plug and the block.



I wanna tinker, but it sounds PAINFUl

don't leave that on for very long, it'll burn out your coil.

One side of the coil is hot, the other goes to ground thru the CDI.

So you got a short on that wire.

decided to just put the battery charger onto the starter and it looked like it was sparking accordingly. I couldnt wait any longer. 4 days after hovering over this engine I needed to see it TRY and run.

Ran down and got some gas, put it together half assed, fired her up!


It sounds like the timings off, can anyone diagnose this?

then I tried again directly to battery, and voila fired up a lot better than before, but really bad still. vid coming in 10 mins

The savage is really voltage sensitive.
A low battery will make it miss and pop.

10 is flat and goes against 4
11 is beveled and the ID touches 10

look at 4, 10 may be hiding there.
