super 8 50 2T derestriction

[ametisti7]

Hello guys,

so I bought this scooter last September. So far i have added a smooth boss, 5.5g rollers and a white Malossi contra spring. I also increased the main jet size from 70 to 80, removed the restriction from the air cleaner and blocked the bigger cancer pipe from the exhaust pipe. Tomorrow probably going to block the smaller one. Anything else i could do to make this thing go faster and accelerate better? Oh almost forgot - its last year's model.

If you took the snorkel out of the airbox it will most likely need a larger than 80 main jet.

Alright something like 86 with the smaller cancer pipe blocked?

Yeah I would start at 85 and go from there. De restricted without the snorkel removed is a #82 main jet, the snorkel restricts the airflow a ton so you will need to be higher than #85

alright thanks a ton bro. just if you know are there any more restrictions in the pipe, and where exactly?

Just the part that goes nowhere, it reduces power. Other than that the exhaust itself is a restriction, if you get an aftermarket pipe it'll boost up power a little.

okay thanks. unfortunately my dad doesn't allow me buying a better exhaust pipe, he thinks it will go too fast 
and finally, is the cdi box made so that it restricts the engine's rpm?

[BettinANDlosing]

For the cdi, to test if its restricted you can rev the engine on the center stand and if a rev limiter kicks in you hear it go brap brap.

okay then it isn't restricted. i'm still wondering that when i installed the new spring it decreased my top speed and acceleration a little. Does it get better over time (the spring getting more loose) or do i need to increase engine power?

and also would this setup work on my 2014 version?

The 2014 has the same engine as the '12. I would say 7gr sliders are too light, and that's why you lost top speed, 5.5g is to light use 8.5 and you'll gain speed.

[Chris0381]

I thought 7gm sliders would be too light and said "given them a try what the heck" but they seemed to work ok with my setup and no decrease in top speed until cold weather set in for some reason.

Once it got cold 50 deg or so, the scooter lost a couple MPH.

What exact spring did you use ? What color- still using the white ? It it highly advised on here to use the purple spring.

Did you cut a slot in the idle air screw to tune the carb ? That can also play a small part in performance.

How did you block the cancer pipe? Pictures please and I think you mean blind pipe. I assume instead of a cut and weld you put something inside to block it like rounded sheet metal or a sock.

my spring was the least stiff Malossi spring, the white one, and it only decreased my top speed and acceleration. today it changed it back to the stock spring.

what does cutting a slot mean? like loosening it a bit or something else?

cant send pics right now but i rammed a screw there from the inside and put some sealing cream, but it didn't seem to block it completely.

im just wondering how would the purple spring do any better? the white one didnt help at all and it's damn more loose. some next level sh** lmao

Theres your problem, you have an exhaust leak. You have to get something welded in, like a bolt or washer plate. If it's leaking all you did is decrease your performance and possibly cause a lean condition. There is NO sealer that works on exhaust, only welding. Don't try anything else until you fix this, you'll be chasing your tail around forever when the real problem is an exhaust leak. Take it too a machine shop and it shouldnt be much more than $30 to get them to totally weld it shut.

yeah probably gonna take it to my dad's workshop and seal it there. and i also installed the size 86 main jet. last thing i was wondering is that it accelerates pretty well now, so what will the purple spring and 7g rollers do to acceleration and speed?
