Hahahhah 

That's funny 

[Super9r]

..it really grabs and sets you on your way, as long as you get it dialed in, along with the rest of your setup...

...here's mine, on nina, and it's the most torquey setup, take-off thru top speed that i've ever been able to dial...

..all these bits are seated in by now, and i'm really liking the way she's performing...

..i'll start at the beginning..

..malossi air filter, oem carb with a 38pj and a 122 main and a redneck needle mod that raises it .025", ngk br8hs (not hsa)  plug indexed to 7:00 (best i could get thisn), tecnigas next pipe( $75.00)

..using amsoil interceptor injected...

..malossi variator and drive boss with 6 gr dr pulley sliders, oem drive face..

..Gates BOOST premium 732-18.5-28 drive belt..

..naraku gy6 styled (unrestricted) driven pulley and torque driver, malossi blue 1500 contra..

..dr pulley HiT clutch set with 31kg clutch spring (next to stiffest) and 9.2kg pillow springs (stiffest)..

..with a warmed-up, hard throttle take-off, nina jumps at 8000  for about 1 second, then launches at 9200...

..maintains 9200 on a flat ground run up to 50 indicated...

..she will peg the speedo, and i mean peg against the side of the instrument panel @ 9800 on a downhill...

..never falls below 8300 up even my steepest hills...

..the best part is, that i can feel acceleration and torque throughout..and that makes riding this scoot ssso enjoyable...


                    

So word,

  Are you still running this set up?  Well with the exception of the belt change?  I am looking to do much the same mods.  You think the neddle mod was a must do? Did it change the mid a noticably? 

I'd like to find a bargain on a pipe?  Retired and need spend wisely if I want to get the ouput I am happy with. 

Sounds like your set up is pretty good with the stock carb.

You think with the stock air box modded I'd be able to get close to your setup? 

Keep up the awesome thread.

You think the neddle mod was a must do? Did it change the mid a noticably?  

..the needle mod is pretty much a necessity if you run a free-flow air filter and a pipe....

..i'm down to a 120 main jet from this setup..

..still running a 732-18.5-28 belt, and it's a Gates, just not a gates BOOST...with the boost, i actually went to 6.5 Dr pulleys...

..Now, with the regular Gates, i'm going to go back to the 6 gram...

..itsa fine line between dropping in and out of the powerband...


..main thing you probably need to do is check your driven pulleys, and see if they are restricted (bet they are) and replace them if so...

..that's easily 10 mph increase

[wordslinger]

...also, make sure the drive boss, and cdi are de-restricted...


                           

[Super9r]

Well I have the Naraku vari, 1500 contra spring and clutch spring set on order. (Boss included)
Have stock driven pulleys and clutch on the 03.

The Naraku pulley set is out of stock so I check the A 50 set at the local dealer runs about the same price as the Naraku.  Not sure which way to go wait for the Naraku or buy the a50 23010-LDC8-C10. advice?

6.5 and 7.5 generic rollers plus the 8.5 stock and the 8 that comes with the vari.

Also the Naraku filter element for the stock box.  No pipe at this point.

With that setup what jet range should I try? What roller and clutch spring rate should I try first?

Thanks
Arthur

 So by your vari thread I take it you would go for the malossi over the Naraku I ordered?  I just initially want a little more umph and topend.  Of course a pipe will get ordered too.  I'd like one on the "quieter" side of tuned pipes.

[wordslinger]

I wore the Naraku var out in no time...Malossi is best variator upgrade i've ever ran...and i've tried a lot of different ones...

...also wore out the Naraku torque driver...it's hard to beat OEM parts...

..There's no need to change jets, unless you install a free-flow air filter or a pipe...OEM main jet should be an 82, and i wouldn't advise putting in that 92..

..as far as rollers and springs, every scoot is different, but the idea is to get initial take-off rpms at or a little above your powerband...which should be @ 7500-8200 on a oem setup..

..then just hold that rpm until you approach top speed....let the cvt do all the work!!

[Super9r]

The 92 jet is listed as the oem unrestricted jet in the service manual.  78 is listed as the speed restricted size.  I'll try the 92 tomorrow when the wifey is at work today is her only day off sooooooo.

Once I get the order and try the stuff out hopefully I'll learn to tune a cvt....more so how not to ore so...lol.

The A50 full pulley assy does come with the derestricted pulleys right?

Thanks for the reply.

[wordslinger]

..well, I bough a complete clutch assembly..a50, and yes it did have correct pulleys ..someone else here bought just pulleys, and the non moving pulley half was from a restricted set....

...that's big jump in jet size without increasing air flow....my 2004 had a 82 main, and the AC super nines generally have a 75 main...

..look at your plug...it should be a nice, dry, brown kinda caramel color...

..in fact, i would put in a new NGK BR8HS plug and ride it a few miles, then look at it..(sorta like plug chop)....

[Super9r]

Yeah i am going to change it and take a look at the plug.  Autozone only had the br8hs I have it and a br8hsa coming in from another store tomorrow.

First I was going to look at the used plug ride it and compare.  It is after all going to be richer so no harm should come of it right?.... Famous last words.

[Super9r]

Is there a stock airbox restriction?  I am pulling off the exhaust to check it tomorrow too if all goes as planned.

Have you done a gps speed on nina?  Is your speedo way off?  Mine shows 50 when my phone GPS shows 42.

I do like the blue color of your scoots too.  But think I'll keep mine black and red.  Might do the back left and right body panels in matte black.  When I order a replacement for the scratched left side I'll sand and paint it to see how I like i matte black compared to red.  The red is really nice and can be seen well from the side.

[wordslinger]

...i've not found any airbox restrictions on any of the s9 that ive seen..


..dont bother with exhaust...it aint restricted...


..ive ran both those plugs...seems the "A" might have ran better in nina oem....hmmmm...

..richer wont harm much of anything, .long as you got a fresh plug with y' to put in if it fouls...lol..

..does tend to build carbon over longer periods of time, which is not desirable....


..i gpsd nina a while back, and she was 6 mph optimistic  @ 40...

..at 55 mph indicated, she gpsd 50...

..i have not had a chance to check since she's pegging the needle...

..looks like 65 indicated....

[wordslinger]

..the really fukn awesome!! thing is, that at "65" ind, nina is only turning @ 9400-9600 rpms...

[wordslinger]

hopefully I'll learn to tune a cvt


..itsa must-learn...

           


..but before that, you MUST know that your fuel mix is damn near spot-on....

..a rich fuel mix could be mistaken for a cvt issue, performance-wise....
