Hello to all...

So when I had my last Sup9 in 2005 I purchased it brand new.  So I never needed to do a compression test because of that.

So what is the best way to do one now that I have the proper device to perform the test?

Easy stuff. Kill switch set to kill. Bike on center stand. Remove the spark plug. I use masking tape to hold the throttle WIDE OPEN. Make sure the tester is screwed in quite snug but don't go crazy. Too tight can tear the "O" ring, and give a false reading. Hit the electric start, and give it 5-6 full revolutions. You will see the gauge jump up a little on each revolution. It usually stops increasing in 3-4 revolutions but you want to be sure it is maxed out.
I usually repeat this twice to verify.
If it reads less than 120 but over 90 you are well worn (cylinder/rings/head gasket) but it will need parts before long, and I would address that first
If it reads less than 90 remove the tester, and pour about a 1/4 oz of 2T oil in the cylinder, spin it over 2-3 times with a rag over the spark plug hole, reinstall the tester, and repeat the test. This will tell if there is a score in the cylinder or just worn parts/leaking head gasket. If it comes back up to the good range it is  worn parts or a leaking head gasket. If it stays low it is most likely a score in the cylinder/piston

If you are within 10% either way of 120 you are good to go.

Ok well looks like I am going to be doing the 70cc upgrade!

I did a compression test this morning and it averaged about 85psi.

So looks like I need to make a grocery list of things to get.

I found out also that the scoot is all stock and there has been no aftermarket upgrades done on it.

I didn't go out and check top RPM because I know that considering I will be making some major changes to the scoot those figures will completly change.

As a heads up again IM a tall and big guy so I need to set this up for that.

So now I need to know exact part numbers and such of what to put on it so I can get it to "Scoot"!

Call Louie. Tell him Ken McLaughlin c/o Max Marine, Carrabelle Fl./Lanark Village Fl. sent you.
He will take the time to get you set up. Buy your parts on my account for wholesale pricing.

Same goes for everyone here. I respect Louies talent, and he is passionate about what he does. He is a career scooter racer, as well as lead mechanic for team Yamaha (retired) If you are not comfortable buying on my account... Just mention me, and the forum. He will take care of you.

I will definitely get ahold of him so I can make my Sup9 "Scoot"!

I'm putting together the "Grocery list" and what he suggests on top of what I "think" I need I will get.



Thanks very much!

BTW...I plan on documenting in photos each and everything I do to the Sup9.  I work at Apple as a Creative (Instructor) here in Denver and also shoot professional hockey and lacrosse.  So I kinda know a thing or two about making good in depth videos and photo presentations about stuff.

As soon as things start showing up I will start the tinkering!

BTW...

What is the main difference between the Malossi Fly and Delta Clutch?

I know that one is almost double the other in price but I also notice that it looks like the Delta would be more able to tune specific to your style of riding.

I don't know if that is something that I would necessarily need but it would be a nice thing to have if I plan on really dialing in my scoot.

I just posted a reply to the same question...

The fly is a OEM type, and the Delta is a race type. You WANT a race type for one simple reason (as you noted) tune ability.

I have a six year old Delta the has been on three bikes all using different bells, and it is still on the same shoes that came with it. It is BULLET PROOF! But. The stage6 is much more adjustable for fanatical tuning. I like it better than the Malossi but I have much more power than the Malossi is made for.

Ask Louies opinion, and he will guide you in the right direction. He is NOT a profiteer. He IS a scooter racer.
Tell him exactly how you intend to use the bike, and nothing about whatever fantasy ideals you may have. The intended use determines the components. Fantasy use, and we would all have bi turbo / blowers / Nox, and wheelie bars with a switch to give us everyday riding economy.

Give up a few MPG for a few MPH... Fine
Spend a few xtra $$$ for a longer lived part... Fine
Spend several thousand for Loads of MPH, and longer lived parts... Fine
Spend 100.00 bucks, and expect all of the above... Stupid

Your best spent $$$'s will be on the clutch, and then the jug. and then the pipe, and then the carb/intake.
A good clutch makes any bike perform better.
