365 BB Kit

Ok, I think I'm ready for assembly. I may sharpen the bottom of the cylinder spigot next to the transfers. I shaved her down .026" last night, so I should have my .020 squish.

Nice. I'm anxious to see how it runs for you.

 

[bjorn773]

Brad, do you usually taper the spigot area next to the tranfers toward the bore(sharpen)?

No I do not. I'm assuming you did curve the roof of the exhaust a little more? I kind of fell off the wagon on this thread. Sorry.

 

[bjorn773]

I did. I can't seem to get a good picture of it though. The center of the port is the last area to show light when I put a light in the plug hole above. I would be nice to have a bit more arch, but I'm nervous about raising the roof much more. I have a very good bevel/chamfer, so I think I'm good to go.

I agree with what you're saying. I hate raising the exhaust in most cases. Racers run pretty flat ports and get away with it, perhaps at the expense of ring wear. Furthermore, most guys bolt these on as is, even with convex shaped roofs, and get away with it. I think you'll be fine. Gonna have it running today?

 

[bjorn773]

I have to get it back together yet. It's looking to be a busy day here at the shop, so I have to make money before playing. Hopefully I'll assemble at lunch and rip a few rounds tonight.

What's a good number on ring end gap? I have .008" on one ring and .007" on the other. Is that too tight?

That's great!

I torqued the cylinder down with the old compressed gasket with a very thin coat of aviation form-a-gasket. My squish is .0215" I guess the sealer must account for the extra .0015"
Am I better off not using any sealer? It's a paper gasket in good shape, I was just concerned about the seal being a used gasket.

I'd leave it as is.

 

[bjorn773]

Will do, thanks

 

[blsnelling]

You'll never see the difference of .0015".

The moment of truth has arrived.

Looks good.....does it run?!?!?!?

 

[bjorn773]

It fired right up... the carb was way out of whack, but once dialed in it runs strong. I need to get into some wood... soon

I have to cool it down enough to pack into my harley tourpak. Once home, I hope to be able to slice some rounds.

 

[TRI955]

Good to hear!!!!

HAHA!! It looks just like the 365 I put a BB on!! Same bar as well!!!

LOVE this saw!!!

 

[bjorn773]

Well, I got home and put the b&c back on. Then headed right over to what was my splitting stump. I started cutting cookies... man this thing really flies. It's definately a different feel than the 385... I see where it's hotrod stigma comes from. I think it may just give my 385 a run for it's money. It sure is a more exciting feeling, quicker revving. Once I find some more wood to cut, I'll try to shoot some video. As for my old splitting stump... may it rest in peace... or should I say pieces

 

[blsnelling]

Great news. It's probably faster than the 385 in fair sized wood, but I doubt it has near the torque. That's where 385s are impressive. Now you just need to port your 385
