Super 9 / Is Technigas RS II the only exhaust available with a BBK?

« on: August 16, 2011, 09:12:00 PM »

I am upgrading to a 70cc Malossi, and getting a 19mm carb (Probably Arreche) and shopping for exhaust pipes.

I am interested in a couple pipes including the Yasuni C16 and Stage6 Pro. The Technigas RS II is an option as well, I currently have the Next R with the stock engine. I can't find any other options for the Kymco other then the Technigas from a couple places. And those places only have it in chrome.

Anyone have any online resources where I could check out other pipes available for the Kymco or is the Technigas RS II in chrome the only option available?

Super 9 / Lets talk tires

« on: July 17, 2011, 04:34:29 PM »

Just curious what everyone is using.

I had the original up front and it was getting dry rotted ( 4 years old & 15K km) and I needed to replace the rear anyway. It was the third rear tire I have gone through due to nails and plugs that wouldn't hold up.

Anyway I picked up the Michelin Pilot Sport SC for the front and rear. The difference is amazing; the grip is excellent (dry and wet), ride nice and smooth, absorbs small bumps well, and begs to be riden at an angle......... so much fun around turns now. I highly recommend this tire. I never imagined there would be such a noticble difference just from a tire upgrade.

Anyone else have a preference?

Super 9 / Squeezing a little more power, modify airbox and manifold?

« on: June 21, 2011, 03:48:22 PM »

Hi all,

I have an '07 Super 9 AC that has been good to me, 15,000km good so far. Early on I played with the transmission; upgraded variator, stronger contra & clutch springs, played with the roller weights. I also put on a tuned pipe and opened the jet a little. It is pretty well dialed in and I can get it to top speed with consistent RPM's all the way through to about ~45MPH depending on the wind. (Speedo indicates 50 or more with needle to the M in MPH on speedo).

The next obvious upgrade would be a 70cc kit, pipe, and carb. But until then I was thinking of modifying the air coming into and leaving the carburator. I have an upgraded manifold that is a couple MM bigger in diameter then stock and noticed the hose from the airbox to the carb seems restrictive as well. I saw somewhere (yahoo groups?) a mod to replace that tube with a radiator hose.

My question is would opening the airflow to and from the carb a few MM provide any additional power? I have read the only restrictions to the AC in the USA is the speedboss, exhaust and air intake and not the CDI. The manifold I have is for/from a Canadian version of the S9.

Is this modification worth it? Obviously I would have to adjust the jetting........... just wonder what kind of (if any) performance increase should I expect.

General Discussion / Question about a warranty issue

« on: January 01, 2009, 03:14:14 PM »

I bought my 07 Super 9 back on 7/31/07 new, put 9700KM on it before I had an issue. I have heavily modded the CVT, only engine mods were a performance pipe and drilled the main jet a size bigger to accomodate it. This pipe and jet mod was done around 1500KM. I have used BelRay Si7 2 stroke oil consistently, it has never drank any other oil. The CDI or rev limiter was never altered.

I was riding at WOT (like I always do) when it stopped. I knew the piston was seized. Took it to the shop, they found a piece of metal had got into the combustion chamber and nicked the piston head, top of the piston, as well the side skirt but couldn't figure out where it came from. They installed a new piston and jug not knowing if it would be covered under warranty because of the exhaust pipe mod. After installing it they noticed it still didn't sound and feel right so they split the case open.

They found a main bearing next to the crank had failed. The piece of metal was a part of the bearing cage that holds the ball bearings in place. As a result pieces of this bearing worked it's way up the transfer ports, damaged the gears for the oil pump as well the piston. The dealer ordered and installed; a new piston, new jug, new head, new crank, new main bearings, and a new crank....... basically a new engine top and bottom. Over $500 in parts alone and 8+ hours of labor.

Kymco wants pre-authorization for any engine work greater then $250. Because the dealer had already invested in installing a new piston and jug splitting the case open took the repair over $250. They feel that Kymco will cover it and commented no mod would cause the failure I experienced. Kymco is dragging their feet though, they don't open until the 5th of January and the Dealers bill for the parts will be due before Kymco decides.

As a result I gave him $300 towards the repair to get my scooter back and out of his shop. If Kymco denies the claim then I will have to pay the balance (he will charge me cost on parts, help with labor rates) If Kymco approves the claim then I get back $200. Either way I am out $100, why? Is there a deductable for engine repairs under warranty? I was going to ask the dealer but he is gone for a while.

Do you think Kymco will honor this? If not then why not? What is the $100 for, anyone hear of this?

Thanks in advanced and happy new year!
