I've had my eye on this motor for over 10 years at the junkyard but he always wanted way too much for it. This trip I discovered the situation there was only getting worse - pigeons.
It turned over still. After he gave me a much more manageable price of $150, I manage to.. uh hum.. scrape out enough to get a socket on the head and remove it - STD bore.
Took the plunge. I'll follow up after some serious poo removal.
:jaw:
dude.
:whistle:
Oh my...
Is that "stuff" corrosive?

I've always heard it can be, especially to raw aluminum. Plan on plugging holes and spraying it off this evening. From far away.
id put that thing in the bed of the truck and hit the automatic car wash like 7 times. maybe 8.
Yuck!
That's love right there.... damn!

Polishing a turd after pressure washing it first
I can tell you that chicken shit is very corrosive...I'd buy the BIG jug of WD-40 on the way home from the car wash...
WOW!
And I thought some of my projects were rough...
The diseases in there may change the world.
Motor cleaned up fine enough! I think the poo actually helped strip the crummy rattle can paint job so that's a plus.
Engine now 100% broken down and dried off. Unfortunately I am not the first to crack this one open - had at one time had a detonation and was rebuilt, however it was all correctly assembled and seemed to have been a good job. Crank bearings are way tired but not the rod bearings :umm:
So I was puzzled about the look of these pistons, and after a parts number search they are as I suspected - Banshee. 1UA00 stamped inside so they are OEM Banshee pistons.
Without the tang removed, how well would this have run??
Although it is recommended to remove the tang from banshee pistons, I have seen quite a few posts where they were run without being removed with no problems.
As long as the skirt is not worn causing the piston to rattle it seems to work.
Still cut mine though.
Looks like you did well!
It's worth it for the cool story you'll always have with that motor!! I've had to pull topends off and cut the tangs to quiet noisy motors guys didn't cut the tangs on.. you won't notice as much on: a tight bore, nice chamfers on the intakes or intakes not enlarged at all but it's noisier. once just to see i looked at the wear on the tangs and just removed that much which was about half and then rounded the edges and chamfered the intake worked ok but why not just remove it? The engine actually wants as much piston out of the way of the intake air path as soon as possible.. i'd love to see someone make (single ring for racing 2 ring for street) pistons with cut outs instead of windows for the RD350 & 400's...
