Hey are there actuall three different covers? I thought there was only two? Anyone, anyone.

Aaron

 

[aaron]

I thought there were only 2. And is very similar, but I never seen one like it. I have to take a picture and post it cause its pretty funny.

Aaron

 

[aaron]

The on the left is Scotts, the middle is mine that I fucked up the bottom, and on the right is a vert cover.

 

[aaron]

Oil covers are apparently different from vert to sloper. These pictures don't show as much as I'd like the triangular hole patern difference, but you still might see it.

 

[aaron]

Yeah... I never noticed until recently. I welded up the crack in my oil cover but could user another head cover if you've got one.

Aaron

 

[aaron]

Scott,
I cracked it on one of my get offs that Joe doesn't think that I ever have. I didn't realize it was cracked until (obviously leaked oil) I looked at it from the back. It was good practice welding aluminum. I can weld aluminum ok, but need to work on it. I didn't realize that there were to different types of oil filter inspection covers so I figured with all the covers I thought there, now there are only half as many.

Making brackets to mount it wouldn't be to much an issue, mounting it so the oil holes that feed it would require some brains.

Aaron

 

[aaron]

Oops, I fucked the breather baffle up on the head cover by tampering, and the oil filter inspection cover from the get off. Just to clear that up.

Thankso Branso

PVL packed and leaves tomorrow UPS. The extra stator is not a spare, can you fix it for me? I forgot to send the receipt for your records in the package so I will send it tomorrow seperately.

I spent a few hours talking shop with John Heeley tonight. After discussing static timing vs dynmic timing I'm glad I switched to VP U4 gas and I would like to statr on adjustable cam chain timing. Can you whip somethin up for before the next event?

Aaron

 

[aaron]

Just that head I've spoken to you about. Do ou want me to melt something else? Wait til you see what I did to the RS? I brake all my motorcycles.

Aaron

 

[aaron]

Yes I meant rotor. I come with my own decoder ring. What is the dynamic compression ratio that would put us in the 96 octane catagory? 8.4:1? I jus learned how to do it, and I came up with what I thought was 8.0:1.

Aaron

 

[aaron]

Alright I went back through it and got 8.879:1.

Also Anytime you want to jump in here and help me would be great...


Aaron

 

[aaron]

Ok now what I get it is with a street grind cam @ 48abc 10.4:1. If this is the case then is the trade off for bigger valve openings a more efficient way to make hp then higher compression? What the fuck? I guess this is where I should just do what you did cause it worked for you, but not knowing I think is sucky. The more math I do the more a stock cam makes sense at loudon.

Aaron

 

[aaron]

Sorry when I said bigger valve openings I meant the duration the valve was open, so longer durations in relation to the degrees the valves open and close. The way I'm reading this is that real compression is at intake valve close @ abdc. If this is the case then less degrees would be btter. Obviously something isn't coming out right but I must get to the bottom of this. I have a feeling it will be more like you'll get to the bottom and then I'll go, "Ohhh.... right... thanks".

Aaron

 

[aaron]

Also if that formula is correct then essentially you can up your compression by making so much valve clearance that your intake never opens...

Aaron

 

[aaron]

ok, that does help.

That was just enough, and at a level I can get. Especially with previous conversations about making and making torque for the 175.
