modifying the crank oil holes
Has anyone tried the following on a 12?

(Me)I have a question about the oil holes on the crank. they look like they have a "tail" I assume its for better oiling?
(Teddy)
They are toward the rotation to help force oil into the holes. One of the tricks I found on the ZRXOA and also something APE does to all their cranks.
Since mine is apart, and i plan on really giving it a hard go this yr(lots of spray  ), I want all the tricks in the book that will help it live. This looks like a way to get more cooling oil to the rods and put less strain on the oil pump. anyone else do this?

are you having a problem w/yr rod bearings?
he has done a mod to his mains (which never seem to have problems) did he also do it to his rod journals?

no problems with rod bearings, Mr X Dot said they looked good(going with a new set after rods are resized tho) but im upping the spray to have around 305hp total (motor plus nitrous) and didnt think it would be a bad idea to have better oiling. since the rod bearings are fed oil from the crank, it looks to me having extra oil forced into the crank at the mains would only put more to the rods. i dont think the rod journals are touched, but i think the "tails" would be away from the rotation if it was done to maybe pull oil out of the crank?

I have seen either no chamfers whatsoever (some factory superbikes), symmetrical chamfers (common) and symmetrical fillets (uncommon). I've never seen asymmetrical chamfers. In the spirit of not messing with success, I think I'd run your bearings just like you did before. If you find that you have some bearing wear issues related to your nitrous setup, then take measures to change the lubrication parameters, starting with higher oil pressure. Trying to divert oil from any part of the crankshaft seems imprudent.
You are going to mag, true, balance, index and micropolish your crankshaft now that it's out, right? If you really want to get your swerve on, you can try some surface treatments like WPC microdimpling, NeoSeal or whatever got Josh Hayes disqualified from the Daytona 200 last year.

I might look into that. What's included with a stroker by marine?

Tim,
where do you get this stuff? 
I had to resort to google:
get your swerve on
Pronounced 'shwurve'.
US Basketballing term brought into common useage with the meaning to fall into a set pattern or playing rhythm
get your swerve on
To get so intoxicated that walking in a straight line becomes impossible.
Get your swerve on (past tense use):
Lyndsey sure got her swerve on Wednesday night; she was so drunk, we had to help her walk home.
to get your swerve on
(v) A compliment of skill. If you are about to get your swerve on then you are confidently preparing to enter the conflict. If you got your swerve on it means you accomplished something skillfully.

I emailed Marine about mag, true, balance, index and micropolishing the crank, also asked about a possible 2.6mm stroker but I doubt that will be in the budget. I actually want to get this built before next fall....

It takes - no shit - about ten minutes to do a true/index/polish, and it should only cost about $30-40. Magging is usually another $25 or so and balancing is another $50. All of this stuff can be done same-day by a competent shop, even if they have to outsource the balancing or truing, as few shops seem to do both under one roof. Out here in Perpetualsummerland, Marine, Castillo's and Automotive Balancing all swap stuff around according to who can do what and when.
Stroking a crankshaft, with subsequent nitriding, could take some time. The crank builders like to nitride in batches to save money, at the expense of time. I would recommend doing this on a spare crankshaft - even one with some light damage to the journals, provided there are no deep cracks - in case anything untoward happens either in terms of the crank itself or to the schedule. A friend of mine who's building an experimental aircraft engine waited over 13 months for his crankshaft to be radiused and nitrided. Not an uncommon occurrence, BTW.

Re: Getting my swerve on.
I picked up a lot of stuff from Chapelle's Show, back when Comedy Central was still funny. That phrase, along with, "I didn't know you liked to get wet!" (Wayne Brady, upset that Dave said that he made Bryant Gumbel look like Malcolm X, coerced Dave into smoking a sherman) are two of my favorites, especially when they're used out of context or inappropriately (e.g., staff meetings, expense reports, Christmas dinner with the in-laws, etc.).

theres snow here way over my knees  ..... I could use the bad crank that originally was in dads bike. we bought it in pieces and a new crank was included (guy lost intrest in fixing it) it has 1 bad rod journal. if its in the budget... that would really even the playing field with the 14s

Send yr crank to David Eden at Marine Crankshaft in LA.
he won't take months to stroke it. Ask him at the onset how long it'll take, and he WILL give you an estimate which he will meet. Generally 2-3 weeks, sometimes a bit longer depending on shop loading.

APE did that crank. From what Jay said, they do that mod to most all their cranks.

Just call Mr. Eden from Marine, he always seems to answer the phone. They can do perty much anything you can think of. Jay is a good guy as well, you can PM him on SH.org site. I think APE might be a little bit more pricey.

I agree with Karl. If Marine gives you a time frame they will meet it. They have always given me a time window on repairs, weld-up strokers, removing a counter balancer gear, etc.
The only time he wouldn't give me a time frame was for my billet but that was a custom stroke with offset journals, etc...Not just an off the shelf type piece. That one took me 8 or 10 months to get. I'm sure they wait until the get a few orders together for billets before the even start cutting the bars.
It was worth the wait.

David called just now, my crank is ready to be shipped back to me
On Jan 10 he received my #1 crank to check, straighten, polish.
At that time he said he'd "get to in about 2 weeks"
damn! 2 days late!
(but i betcha it was ready on Friday, 1 day early)

got an email back from Marine
Scott, we can check the crank out. Magnaflux, straighten, balance & micro-polish for $175.00. We can stroke the crank 2.6mm, which includes all the above plus detail & ion plasma nitride heat treat (surface hardening) for $925.00 (without balance $850.00) All journal diameters will be stock.
Regards
David
not sure if ill get the stroker this yr or not.... have to ship Jim the head and get the chassis work done first

You might ask him to check the index too. For some reason, I often mistake "index" for "check index" when I write, even though they are vastly different things. Checking index is measuring stroke lengths and timing, whereas indexing is the modification of stroke lengths and timing to a fixed set of dimensions. Checking index is cheap and easy to do. Indexing is obviously much more involved, although it should be part of building a stroker crank.

thank you Tim. i was just getting ready to ask what indexing was !!
i like that little oil hole mod tho.. wonder if there are proven benefits? i'm sure theres something positive on it's side..

I hope Brenda Sue doesn't mind me showing you guys a picture of her crank. This is the crank from her ZX-11 originally built in 1998. Note the oil holes. This was not my idea but was something Steve Rice used to do on his
500 hp ZX-11 Funny BIke. Since he used stock cranks and he ran them a whole season before a precautionary change-out, I figured it couldn't hurt. He said it improved the looks of the bearings.
