boot to reed cage gasket

[Foxx4Beaver]

absolutely....whomever you send the cylinder off to, make sure you let them know it's cracked...take a black Sharpie and mark where it is. Most places are pretty good at looking for, and finding cracks on their own...but you'll be better off pointing it out. Check it really good for others too, around the intake bridges and exhaust.

probably a good thing I looked at it.lol I already spoke with millennium technologies and plan on sending it to them. I guess a $450+ top end job is cheaper than a total rebuild.

[1FAST450R]

Is millennium technologies the best place to go? I want to get done correctly so i'm not rebuilding again too soon.

[Foxx4Beaver]

if you're closer to the west coast, then I'd go with Millenium....if you're closer to the east coast, then I'd go with Power Seal.
Either place is good....it just comes down to "turn-around" time...choosing the one that's closer to you.

[1FAST450R]

im in Maryland. I will look into Power Seal.

[Foxx4Beaver]

Power Seal's in Pennsylvania...so it should be the better choice.

[1FAST450R]

and their prices are cheaper. that is always a plus.

[1FAST450R]

how does this look in your opinion?

[Foxx4Beaver]

not that good...hard to give an honest answer without actually having it in hand, but the crack was the 1st thing I noticed...very little, to no cross hatching left in the cylinder walls...it "looks" like the plating started flaking off around the exhaust port.
It's ready for a fresh top end.

[1FAST450R]

Yep. Exactly what i was thinking. Not bad considering that it was the original top end. I had planned on doing the top end this year anyways. Sucks because the weather is finally starting to turn. Guess I'll just have to ride around on the lazyboy(KQ750) for a while.

you're definitely going to want lap the cylinder AND head mating surfaces before you start putting it back together!....so when you get it back from the plater, don't put the cylinder studs in until you're absolutely sure the mating surface(s) is/are flat, or you'll stand a good chance of having a head gasket leak...then you'll have to pull it apart again and start over...which is what I'm thinkin the previous owner neglected to do, hence the red sealer.

[1FAST450R]

Will do. Thanks for all of the info Foxx. I greatly appreciate it.

well i'm sending the cylinder out to powerseal today for repair and plating. got the other goodies in and now its just a waiting game. just in time for the good riding weather!!!!!

[Foxx4Beaver]

nice!...good to see you got new studs and nuts!.

[1FAST450R]

yes sir. took your advice on that one. its worth it to make everything fresh. hopefully i can get another 16 years out of this cylinder. i actually called the po (original owner as well) and asked if he ever replaced the top end and he said no. so 15+ years out of a top end isn't bad.lol
