Super 9 / Re: tune up
« on: February 04, 2009, 01:44:31 AM »
Go to the tuning tag and you can see what is needed to make your super 9 faster than a GY6 150cc.
Super 9 is a 2 stroke, you don't change the oil, it burns it off and you have to make sure you keep the
oil tank topped up. Under your seat you have 2 tanks one for oil and one for gas. You don't change the oil you just
top it up as it gets burned away.

"What Air Filter do you guys recommend with the Arreche 19mm Carb?"
Any K&N style filter. Make sure you check your plug, it should be brown after a WOT run.
Adjust airscrew about 3/4 turn out. That means all the way in to the stop and then back out 3/4 of a turn.

Super 9 / Re: Which is the best 70cc Cylinder Kit?
« on: January 21, 2009, 04:57:29 PM »
Airsal, even though it is not the most expensive. Cast iron cylinders, like the malossi and Polini are prone to cold seizing. This is because the piston is Aluminum and the cylinder liner is steel, they have different rates of thermal expansion which leads to the piston nipping up in the cylinder if held open for a long time. Also the airsal has really aggressive port timing and a massive exhaust port. When coupled with a technigas pipe and arreche 19 (or even better 21mm) carb you along with a Universal Parts GY6 no rev limit CDI, you are looking at a scooter that will see off all but the fastest 150cc 4 strokes. We don't get the fastest 4 strokes here, they would be Gilera Runner, Gilera DNA etc.

You can use it with the 50cc too. It will give you more revs which will mean more top speed. However, if you want to hold that speed up hills and have much much harder acceleration you need to get the 70cc kit and the 19mm carb too. You will get between 60 and 65mph with blinding front wheel skipping off the ground acceleration with airsal T6 cylinder kit and the big carb.

No rev limit CDI is made by universal parts. This is the one I used. With some plugs you may have to disconnect the wires from the plug and the new CDI and attach them to the old plug, although in my case I didn't. Someone else I know had to do that though.
I know it says for GY6 150cc 4 stroke engines, but they work fine on Kymco S9 air cooled also. Remember CDI the the only controls peak revs and advance and retard. The signal of when to spark comes from the magneto/stator, it is just advanced or retarded a little by the CDI. This CDI works perfectly. Spark Plug is biscuit brown and it revs to whatever your port timing will allow, which in the case of the Airsal T6 is in excess of 12000rpm. With an Airsal T6, Technigas pipe, Arreche 19mm with 90 main jet (comes with a 72 so make sure you order the bigger jet when you order the carb), 6 gram variator weights, and universal parts cdi and it will do in excess of 60mph and out accelerate a standard GY6 150cc scooter.

Super 9 / Re: Tuning new Super 9 AC?
« on: January 15, 2009, 03:41:34 PM »There is no rev limiter in the 07 CDI, buying another is a waste of money. The exhaust is very restrictive due to all the new emmissions standards. The "boss mod", a tuned performance pipe, bigger main jet, and lighter roller weights I got mine to 50-55 indicated with the Technigas type R pipe the biggest performance gain.
I have also replaced the contra spring with a stiffer one which eliminates the low RPM's coming out of turns, up hills or off top end after a breif deceleration..... no more flat spots in accelerating now and the RPM's stay in the peak powerband.
There is a rev limiter. What happens is that when the revs hit 8500rpm the CDI retards the igntion, which stops it revving any higher.
I just tuned an AC Super 9. I got the "power pack" from MHR Racing in FL. It consisted of a Technigas pipe (they forgot to include the vario weights and are sending them seperately) it also has an Airsal T6 73.6cc cylinder kit (with head) and a 19mm Arreche carb. It made a huge difference, but top speed was still only 50mph. It was hitting the 8500rpm limit on the CDI. I tried to find an after market no rev limit CDI, but couldn't find one anywhere.
I had a GY6 no rev limit CDI sitting in the garage (GY6 are the Chinese 150cc Honda clone scooter engines, used in all 150cc scooter and buggies from China) I thought, it's not going to hurt to try this, so I popped it in, the plugs where the same and it fit fine. I started the scooter and it ran fine. I did a top speed test and it did 62mph and revved to over 11000rpm (fitted with an after market rev counter). I did a plug check, and it is a nice light brown, which is exactly right. So for 60+mph on an AC Super 9 you need the following. Arreche 19mm carb with 90 main jet and K&N style filter, Technigas exhaust, Airsal T6 70cc kit (73.6cc) and a GY6 no rev limit CDI. It will plug straight in. BTW, it doesn't matter that the GY6 is a 4 stroke, the CDI doesn't control the amount of sparks, that controlled by the magneto, it just controls advance and retard, and it works perfectly on the Super AC. Next step is taller gearing from Polini, that should give 70mph.
