Best Zuma Parts Package 1

[marylandmark]

Here is what I am looking for-

what is the best set up and the set up you would order and WHY.

I am going for a stage II so I need:

70cc cylinder- what brand and cast or aluminum or whatever else.

carb- brand and size and any other things I should order just in case (needles, extra screws/bolts in case some thing strips, etc)

Pipe- what kind and finish and whatever else I should know (04 silver Zuma so crome or ___?)

Variator- brand and whatever else I should know?

Belt- Kevlar or stock or brand name or ___?

Clutch springs- 195lbs rider on slightly hilly terrain that is 0-235 feet above sea level. I don't care if I have to order every spring out there- rather have them on hand than not but would like to save $$ if I can by not doing that...

Airbox- get one, don't get one or hole saw with dirt traps like these:

ANYTHING ELSE I FORGOT?

TOOLS NEEDED? I can buy them and if whoever ends up doing my mods brings theirs I can return mine or keep it if I would ever use it again.

doppler s3r variator is a good one, they are rollerless!!

[Lennox]

Mark, have you decided on anything yet?

Where do you find those dirt traps? These might work for venting the tranny cover??

[marylandmark]

Just got back from the weekend and haven't ordered any thing at all yet...

search for Uni Air Box Vents

What is the deal with this doppler s3r variator? Anyone have more info on it?

Lennox or Jered- if this is better, why didn't you go with it?

I've ordered 95% of my parts from provo... Just was easier to order them from one source...

I am planning on looking into the molassi kit that is out now... Supposed to be about $260 or so... and it's a large top end replacement part... Should push the top up a bunch and still maintain the take off... from what I've read anyway...

THIS is why I started this thread....

Why are you looking at this brand instead of the one you already have? Did you hear they were better before you bought what you did or just not happy with the results you have gotten from the brand you have?

THANKS for everyones help!!!

If someone "waste" $$$ it is nice of them to try to help someone else from doing the same since we are all in the same boat and just want our scooters running quicker/faster when we do these mods!

[XPS1210]

the molassi kit is on the molassi web site...

I found out about it after I ordered and installed the current parts I have...

I am interested in it as it's supposed to add more top end...

my Airsol 70cc blew up already. It was caused by a leaking head gasket. There was so much expansion/contraction that the head bolts loosened and caused an air leak. Also, A tip to everyone..... remember to re-torque the nuts!!! stay away from an aluminum cylinder.

Luckily I

[marylandmark]

??

When did that happen?

WOW!

Sorry 2 hear that!

[larry-new]

...from what I've been able to glean around these parts....

It would seem that the "performance " parts available are a lot of work (both in install and tweaking, and retweaking...), not to mention $$ for the increases gained.

Remind me to tell when I put a 4bbl on my baby blue '60 Buick conv., and the gasket dumped fuel, causing a fire...pushed it to my friend's junkyard and traded for a '59 Desoto (413ci, w/. pushbutton auto...a MUCH faster car)

I digress. The parts sold here, and the packages, info, and great effort put into making the perf. thing easier are certainly nothing to put down, or belittle... If and/or when I do get perf, parts, it'll be here.

For now, I'm looking, reading and cheering on you pioneers who go for the rockets....

Larry (2004, 250 mi.. 38 mph)

[marylandmark]

LOL-

I was thinking the same thing for a bit as well....

I am going to end up doing the mods but not too wild- just trying to find out the best package to put together to try to avoid some of these issues.

NO such thing as reliable mod but if I can tweak my setup a little to make it not such an extreme mod and keep it FAIRLY "run-able" for the most part then that is what I am going to do.

I don't enjoy working on bikes so not going to even try- which means I have to pay someone for every thing I need done. Get a real wild setup that needs rebuilt every 200 miles is not in my plans.

[Lennox]

my boss walked in on me earlier, so I couldn't finish....

Luckily I have a spare cast iron 70cc kit sitting here. Last night, I put the stock jug on and GPS'd. To my suprise, with just the pipe, and carb (I took of the vari) I was still able to get a top speed of 46. The acceleration was terrible though.

Either tonight or tomorow, I will go back up to the 70cc (cast iron this time) and do some more testing.

Larry I appriciate your opinions. The way I have been looking at it, is that these scooter parts are WAY cheaper than ski parts, Harley parts, or truck parts. In a sick demented way, I am kinda glad this happened. It will give me a chance to experiment with more different parts. LOL!!!

Before long, I will come up with a bullet proof package that is FAST!

Pretty much what I am looking for right there...

I know some things about other motors- like a boat motor. You can take a 572 block and get 1400 HP out of it ... going to have to rebuild it all the time and can blow at any moment. Take the same parts, detune it to say 950 HP and will run much longer with little to no maintance. Stuff is designed to go to "X" HP but only pushing it 70% so last longer.

[Lennox]

Although your statement is 100% accurate, I still hate the words "de-tune":D LOL

I am an optimist, and say the same thing like this..... "Tuned to its safest potential.":)

...Thanks all for the feedback...I'll be watching closely!!

Now, back to a earlier mod try....tires.

The 2004 has the absolute largest (130/90-10, 120/90-10) tires made...but...but....if someone could measure the circumference of a couple of new tires...there might be variations...

The Pirelli brochure lists the complete dimensions of all tires, and there ARE tires in those sizes that show variation. My local cycle stores (motorcycle stores with a few scooters) do not stock enough tires to make any comparison. Rochester, NY has a dedicated scooter store....hmmmm....

I chose tire size as a mod that might increase performance (top end) with almost no down side...nothing to tweak or come untweaked, as it were...

Going back to basics, it would seem that changing final gearing would also be a fairly easy way to get more speed...am I right?

Larry

[Lennox]

just remember that final gears will hurt your acceleration.

[larry-new]

just remember that final gears will hurt your acceleration.


True...but a, let's see....a 15% drop in acceleration might not be very noticible, whereas a 15% top end increase ( 38 x .15 = 5.7 = 43.8) might be more helpful. A 25% increase would yield 47.5 mph.


All this is not a desirable as a real increase in power on both ends, of course......I've a lot more studying to do...

L.

[Lennox]

I don't know for sure, but IMO the stock configuration would not be able to get the RPM's high enough to gain that many mph. (in less than a couple of miles)

[larry-new]

ahhhh....

Looking over the stage 1 (for the seventh time or so) I can see the thought that has gone into that package...

Any ideas about how long these mods might take a reasonably able dude?

On a Zuma, an hour the first time, 30 minutes there after.

...for the whole bloody job??

[XPS1210]

...for the whole bloody job??


I could, with all the tools laid out... Take my scooter from stage 3 (and a little beyond) back to stock in under 90 minutes...

I can take the 70cc kit off in less than 15 minutes... Change weights in less and 10 minutes... remove the body panels in around 5 minutes...

It's not to hard once you have it figured out the first time...

Now the 1st time I installed everything it took maybe 2 1/2 to 3 hours... this was with figuring out how the heck to hook up the stock throttle cable to the new carb... (as we all know I dremmeled it to the smaller size)...

The mods aren't hard... the HARDEST and the thing that'll piss ya off the most is.... CARB adjustment! 600 miles later and I'm still F**King with it....

[mikhail masevich]

Jered check out this zuma. It does 55mph What do you think with a Polini big bore variator and weights. Why is your zuma so slow! If this guy is not lying Polini is the way to go man! Believe me man

[XPS1210]

my zuma is slow because of a curse! Grrrr......

[larry-new]

,,,I don't suppose that, say, a cycle shop would have a machine to adjust a carb w/o the plug read thing....

[Lennox]

an EGT! exhaust gas temp guage is THE MOST accurate way. #2 is a tach, then #3 is sound, and finally #4 is plug chops.

So, who around here uses what?? And what are the basic parameters? E.G., what does a higher/lower EGT reading indicate? Would a tach indicate correct carburation?? How? Sound, eh?...hmmmmmmmmmmmmmmm

Larry (who passed his road test today!)

[XPS1210]

1st, Larry you the man... passing the motorcycle test! :D

2nd, I have only used the plug chop... however I am finding it almost impossible to do this method as I run a high end full synthetic... It takes a while to get a "run plug" read as it burned pretty clean... however I for some reason have determined that my scooter likes to run lean!

It hates to be even slightly rich.... it loves to be lean... Not so good... but it's still a matter of tuning it!

[Lennox]

This is the EGT I have on my Waverunner. http://www.racepak.com/ProdFrame.html

As for the scooter, http://www.tinytach.com/tinytach/index.php this works good for scooters.

As I have said from the begining, plug chops are the WORST indicater.http://www.racepak.com/graphicfiles/F2-D1_files/image004.jpg

[XPS1210]

got to be... there is no way that anyone has a zuma doing 70... Unless it has been completely changed and there is nothing at all stock...

I'm HOPING for over 60 with upgears and a new CDI... (in addition to all the other stuff I have done...)
