    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Go more on the screws or needles?

Can't remember the last time I did a redline run except when I stopped at neutral on my way to 2nd. LOL

Yes, I agree posplayr, I fully intend on giving her a mild "shakedown" ride and check the plugs before buzzing down the highway at 7000+RPM.

Finding out I'm too lean there would truely SUUUUUUUUUCK! I've had the pleasure of cleaning melted piston off the inside of an engine block with one of my stock cars, huge fun, oh yea, loved it..........
 
If you noticed a change due to the exhaust you might be in for a change to the mains which means the needle might need being redone. Best to wait for the rain to stop before doing any redline pulls though :eek:
I have to immagine this has happened over time. It seems louder than when I first punched the exhaust out. I'm guessing the "stuffing" is slowly exiting the pipes now that it can get out. At some point it will stop I immagine. And like I said, I've added a .875" hole to each side. I first drilled them with a 1/2" drill then knocked the rest out with a 3/4" dowel. When I used the dowel there was at least .063" a side of room for it, and I made sure I got all around the edges good too....

Just out of curiosity, you don't red line it so you are obviously not after more power...
So why go through all of this? Pipe punching and jet changing and all of it?
 
Pipe punching is because my seventy something year old mother gave me the bussiness about my little bike being too quiet. " Son, you have to get louder pipes on that thing, it doesn't even sound like a motorcycle". Go figure, I'm still listening to Mom.

As far as getting it to run at "peak", I have built and drove race cars for over 20 years, (retired for 10+ years). Successively at that. I hold several records locally and the guy I built race cars with still does it in WI for Coleman Chassis. He uses the designs we both came up with years ago and the car he currently is working on has allready clinched the local championchip. And I am an engineer that designs and personally builds automated printing equipment.

To answer your question without the long disertation......... because Mom said so and I have that stupid, overthinking, get all you can from what you have, rediculous engineering brain...................LOL LOL LOL

OK so she made a suggestion. :-\\\

Whose bike is it? :-k

Is her name on the title? :-k

Does she ride it? :-k

Tell her she can punch out her OWN mufflers. If YOU want a quiet bike, you should have kept it that way. :o

.
 
Agree Steve..... But it's MOM......and I do like a little temper in the throttle too.....I'll work through it I guess. LOL
 
OK, the results are in....(minus the highway run)............ With the needles raised .020" and the screws at 3-3/8 turns out..........SUUUUCK-O! So I put the factory spacers back in the needles and set the screws back to 4-1/4 and......WAY BETTER!

Short answer, it is better the way I had things before.

Thank all of you for your help along the way.

Side note,
When I was doing the coil relay mod I accidentaly sparked my meter probe from one of the coil's + terminals to ground, (the way I had the coil laying there when I did this I should have known better). Anyway, my first thought was, OH SLIT!!! I just butnt out my igniter box. It fired up perfectly fine so I went on my way feeling lucky.

I can't remember who, but someone in this post made hints to check the spark. Now not 10 minuits before, I was running the bike in my shed with no issues. When I was checking the spark, # 2-3 had none. I thought, well maybe the plug isn't grounded properly. So I put it all together and sure enough, the coil that I had shorted a week or so ago had no spark when I started it. I put my spare igniter in and poof all was well.

I guess better to happen in the shed than 100 mile away from home.
