Only five runs tonight

[RacingJake]

I guess she know's how much it's cost to drop a few tenth's

My wife will give my bike the eye sometimes and say isn't that a new thing on your bike. I just say I bought that last year then she gives me a funny look 8O Take's me about 6 months anyhow to get it out of the package.

If you can run 9.80 all day long you could try some heads up racing this year.

Were still getting better. 1.39 60' she went 9.77 at 130 mph off the gas at the finish line. 1/8th mile was 6.16. Pass just before was 1.41 60' 9.82 @134. I had one or two time tirals run 135 mph. I'm starting to get the clutch sorted out. Took me 4 rounds to win the bike class tonight.

[RacingJake]

Congratulations on your Class win !

Hey your running in my neck of the woods with that 6.16 8) If your like me your thinking high 5's one day :twisted: .

Let me know when you have a few run on video's with that 1150 head.

Re: Only five runs tonight

Checked the cranked again and it's not twisted, checked cam timing and all springs, keepers, rockers and chain; they all checked good.

How did you check to see if the crank was twisted?

[RacingJake]

I use a high tech tools....... a plastic straw and a wire tie.

Remove #1 and #4 plugs and set the engine on TDC. Run the straw down the #1 hole until it hits the piston and push the wire tie down around the straw until it hit the top of the sparkplug hole. Then do the same on #4 then do #1 again and see how much of a gap you have. The bigger the gap the more twisited the crank is.

Now this won't tell you if the cranks is twisted at .001 of an inch but I'm not worried about that I'm looking for anything above 1/8.

I do this every time after a weekend of racing just for piece of mind and I've never seen a gap develope yet.

Jake, did you get that shattered thrust washer sorted? Back on the track yet buddy?

[RacingJake]

Not yet Mark,
I've been installing a 24ft above ground pool that i also dug a foot and a half deeper for my kids. You'll be surprized how much dirt can come out of a 21' circle.

It might be awhile until I drop the crank out of her. Most likely send it out for repair. Got my eyes open for another crank so will see whats happens. Until then my Sportster is going to get a good workout.

Hey, didn't you laugh at me when I told you I used tub and tile cleaner on my carbs??? You have a lot of room to talk!!!

LMFAO

[RacingJake]

Was that me....... ahhhhh..... Lime-Away ..... OK it was me, but everytime my wife find motorcycle parts in the tub she goes crazy.

I was thinking of something along the same lines. Just thought I would check with and expert!
Thanks. 8)

Kevin, just saw that you asked this.

Jake, awesome tip. Thanks man. You should put that in the tips and tricks section. Seriously.

I also had another question for you. I want another opinion. You commented
in my leaking seal thread but then never came back.
Do you think I am going to be able to swap out that output shaft seal
without splitting my cases? Or do you know for sure that I will have to.

I want to know because if it for sure cannot be done then it would be
really bad of me to pry out the mangled remains of the seal that is in
it.

Sorry if I hijacked your thread buddy, I just know you drag guys are really
used to tearing them down and what not and may have a better
idea about something like this than us average Joe riders would.

[RacingJake]

Not a problem Mark.

Is your seal still in one piece, no holes? make sure you have the o-ring behind the sprocket spacer that's between the bearing, if that's missing it will allow oil to leak around the output shaft too. You could try and turn the sprocket spacer around so the seal will be touching some new metal.

That bearing half ring is going to be a small problem.

If you have some tools you could try this, drill a small hole 1/8"near the edge of the bearing half ring just enough to go through but not touch the bearing behind it. Then with a punch knock it out without breaking the groove off the case. Once out you drill two small holes 180 degrees apart and install sheet metal screws into the oil seal, again don't touch the bearing behind it. With pliers grab the screws and work the seal out. Grease up the flange area and tap a new seal back in, this will take some time and a few trys. You should be able to re-use the half ring and tap it back in the groove with some lock-tight.

The main thing is to limit the damage to the half ring and seal.

Double check that o-ring on the output shaft, maybe that's the cause.

Like I said it's a SPITA but it worked on my 750

Jake's .02 cents

[Hoomgar]

I replied in the tech section since you posted in there too Jake.

Then I asked yet another question :?

Thx man
