Well, with a few days off over the holdays, I’ve gotten the 305 Dream to the point where I don’t believe there is anything unsalvagable here, and it won’t take an exorbitant amount of money to put this thing back on the road in nice shape. The last few hours of work have been to get the frame stripped of all other parts, so I can start cleaning it and getting it ready for blasting and paint. Here’s the parts that will be going out for paint, plus the tank, once it’s clean inside.
swingarm, front fender, frame
front fork, sidestand and footpeg mount
I have a large list of parts I need (sent off to cyclepsycho to see what he might have), and a couple of unsolved problems. I am as yet, unable to remove the steering head nut from the top of the stem. I think I managed to move it with a pipewrench, so I gave it another soaking in Kroil and will try again later. I still have one piston with the rings firmly stuck in their grooves. and lastly, I broke off a screw in the bottom of the fork (it holds a chrome cover in place over the front swinging arm and shock). I then tried to drill it out, but the drill wandered off course, so now I have a hole through the screw at an angle, and it goes through the threads partway down. Grrrr… I’ll have to spend some quality time with the dremel tool and see how bad off the threads are when I’m done.
the screw that got the best of me that day.
But overall, pretty smoothly so far. at this point, it’s about getting the frame and painted parts cleaned and repainted, cleaning out the bottom end of the motor, having the cylinders honed (bored if they don’t clean up well at std. size), and the start cleaning and re-assembling.
meanwhile, it all waits in a tidy pile. More pics later.
Well, I now have the engine out of the frame, and the cylinder head and both side cases off. The news isn’t all bad. Most of the engine looks in fine shape internally, as you can see here:
obviously, this engine has been sealed up, and has the low mileage indicated by the odometer (5129).
There was a little bit of sludge in the bottom of the side case on this side, but nothing dramatic. removing the cylinder head, however, revealed a whole ‘nuther picture:
obviously, the left cylinder (on the right in this picture) had some water in it for a while.
and looking at the cylinder head, we can see why:
if you expand the picture and look closely, you’ll see that the exhaust valve on the left cylinder (again, right side in the picture) is slightly open. so water vapor got in through the exhaust pipe, condensed into a puddle, which then evaporated and rusted the cylinder.
still, nothing here looks unsalvagable. the cylinders are currently soaking in Kroil, hopefully, i can beat the pistons out pretty soon and see what kind of shape the cylinder walls will clean up into.
thanks for reading. more as i discover it!
Well, I am part way through the disassebly of our Honda 305 Dream project. Some has gpne pretty smoothly, a few bits are being obstinate. One of the easy parts was the cool aluminium carb cover:
the carb cover is intact and in decent shape.
the right hand engine cover is being obstinate, the screws are rusted and only 4 have broken loose so far, and i’m puttin’ the hurt on my impact driver bit. I did get the alternator cover off, and what i found wasn’t really good news:
uh-oh, i think we’ve had some water in here…
After I saw this, I did drain the oil and there was nearly a quart in the engine, so it hasn’t been *empty* for all these years, but it might not be re-buildable. soon, i’ll get the engine out and apart and we’ll see.
Here’s the pile of parts that have come off so far:
headers, seat, battery holder, etc. not in perfect shape, but usable.
So the challenges right now are: how to get the frozen rear brake backing plate out of the rear hub, and how to get the footpegs off so i can take the engine out of the frame. Suggestions are welcome, as always!
