Rebuilding engine

[speedjunkie]

So here is my list of needed parts so far...
-e-shaft
-front and rear irons
-new rear main bearing and possibly replace all other bearings while I'm at it
-at least one new side seal
-probably some new corner seals
-possibly switch to RA Classic or Super seals
-obviously new coolant seals and gaskets, and possibly oil control rings
-spec housings and possibly get replacements or get them resurfaced

I forgot I have my engine from 3 years ago that I still haven't torn down yet. I'm going to break into that to see if there is anything I can use on this build.

Any suggestions from you guys? What new parts should I get?

Eric,

My suggestion to you would be: if the the other engine you have has minimal useable parts, buy a new engine from ray. The price break you get on buying the whole engine new instead of buying it part by part, is huge. Also, I don't care what anyone else says, RA seals are junk, ESPECIALLY the 3mm super seals. I DO NOT recommend them at all.

Experience? Proof? What do you rec and WHY?

In mine they don't break, only warp... saved at LEAST one of my engines. As for chatter marks.... virtually none after 10k

Please understand, my post wasn't meant to contridict yours. I was writting it when yours was posted.

But, my "proof" is in the amount of RA supper seal'd engines I've disassembled in the past 12 years. I have YET to see one that would lead me to believe they are anything but junk, in the form of a "seal that wont break". Sure, they are tuff seals, but they will eat your engine from the inside out. Now, I will be honest when I say, that the 2mm varity usually don't do the severe damage. And in fact, may be considered by some to be "normal(ish)" wear marks. But the fact is, that both the 2mm and 3mm leave chatter marks every time.

I refuse to pay for, or suport a seal that does damage to your engine during its running life just because it's "un breakable".

Kinda figured based on the time, thought it was odd though that you're so against them.

Certainly you've got more experience with these seals than I do. In the roughly 15k miles that I've been using these seals they haven't really left any chatter marks on top of what was already there. I'm also running the stock OMP with an RA adapter and idemitsu plus 1/4oz per gallon in the tank so I'm probably over oiling the engine in certain situations, maybe that's helping? I won't argue that they leave chatter marks compared to the factory seals, but they have saved a few of my engines which is one of the reasons I run them. In my case they've really prolonged my engines.

So, what do you rec?

Yes, the extra oiling is most certainly helping! And I don't have an issue with the idea of "over oiling" ! It does more good than bad in these little two strokes of ours!

I recommend NRS 1 piece for NA and ALS 2 piece for boosted aplications. I also dont mind atkins cryo'd 2 piece seals either.
