Hi

Let me list what I have and what it's doing and lastly what I'd like to accomplish in here. All knowledge and experience are appreciated:

2012 Super 8 50 2T - In Colorado Denver

======Upgrades:======

Malossi 70cc BBK
Stock air filter - Snorkel out
Dellorto 19mm Carb - 91 main jet
Leo Vince ZX-R (Cone taken out)
Malossi Variator - White Contra spring - 6Gram rollers
Malossi Racing red torque springs


=======What's it doing?=========
 
--- 0-5 or 0-10mph is VERY sluggish, then it takes off with full power upto 35mph. Then crawls to 40, 45 and 50 wot
HOWEVER the SLIGHTEST hill, even one I didn't notice it's a hill, it'll make it hard to accelerate from 25mph and up... sometimes it even stalls at 30-35mph at WOT
when there's head wind or side wind.
Steep up hill kills it all the way to 25mph.

So what can I do to remedy this? I also want to be able to hit 60mph mark.


========The parts I'm waiting to be delivered next week:=======

Malossi Primary gear MHR 15/44
Malossi Delta Clutch + Wing Bell (then going down to a sports torque spring)
Malossi Torsion controller
Malossi Red contra spring 35%

Any help is appreciated.

The stock jet is a #82 in the 2t super 8. The 4t might use a #70 but not the 2t. They are wrong about the #70.  You will not go lean with that. I lived in Red Feather lakes ( Mts near Fort Collins) area at 8000 ft in Colorado with not a problem. The exhaust is not that restricted in that scoot. My super 8 2t never got better the 60mpg. With or without the stock pipe.

1. Understood. Will change the jet to #91 . If it is indeed #70, should I still change it to #91?
2. Hmmm.... I already bought the Leo Vince SP3 exhaust... so I guess I'm stuck with it.
3. How do you do a tune up yourself btw? What is it that needed tuning every 2000 miles?
I don't want to have to pay sportique everytime couple of months for tuning if I can do it myself.

Thank you again for sharing the experience.

Thanks for the video, Pimpy, I have been reading all your replies here.

I actually need it to go beyond 50mph, and the above parts are what I was told to get.

The jet though... I'm in Colorado, so we have 1/3 less air here. Plus Sportique told me that they use a #72 , otherwise it'll become too rich.

1. What do you think? And why #92?

2. What do you think of this video: *he has 9 pparts to it and this is part
