Super 9 / Kymco super 9 LC part interchangability
« on: April 06, 2020, 04:57:09 AM »
Hey guys. I've been working on a bit of a Frankenstein super 9 for quite some time due to the lack of fun parts for the scooter.
  Does anyone know if the drive face on the front pulley (the metal plate with the plastic fan blades on it) is interchangeable with the gy6 139qmb one? They look very similar, have the same bore diameter and # of teeth.
Mine skittered off at just over 14,000 rpm (very, very high strung engine at this point) due to some stupidity in starting it with a drill while cvt tuning and ended up in the evil neighbors yard. He has decided he would rather keep it himself and has bribed it for more than its worth  >:( oh well.

On a side note, has anyone successfully put a inner rotor ignition on a s9 LC? The stock ignition is holding up somehow at high revs but i'm sure the timing curve is far from ideal. 



Cheers!

whoops, missed that on accident. Its the lc. Thinking of going with the malossi sport bbk, technigas triops exhaust (would have gotten the trek but didn't see any available in canada and don't want to pay duties) a 90-108 main jet kit, some extra plugs, a roller weight kit and a medium contra spring. I think that covers all bases to start with and should get get me some extra kick. Hopefully I didn't miss anything.

Thanks guys! Exhaust and bbk will likely be on order later this week.
May as well get it all done in one shot I figure. Ill be sure to post here if I get lost with the install or tune and cant find what I need elsewhere on the forum.

Thanks for the quick reply. I assume the malossi sport bbk is pretty much the kit of choice for longevity thanks to the fact that its cast iron with dual rings. Is there an adjustment screw for the oil pump? never heard of one brought up in any off the stuff I've read but given what you just said it must have slipped by me. Tied open would make it run rich as hell on oil during anything other than WOT no? seems too simple to work right to me.. but i have been very wrong before.

Also.. Though this has probably been asked before more times than it should need to be, is there anywhere that has good resources on jetting. Im totally new to carbs and have always gone to injection with all my bikes and vehicles. If anyone has some suggestions on a RANGE of jet sizes (since it would probably be impossible to ask for a single size) that would be awesome. I was guessing maybe 95-110 main and 38-42 idle.I dont really get how the needle works and how that would be resized other than "bigger". Would it need to be touched for just a bbk, maybe a pipe in the future.

Super 9 / jiangwayne exhausts?

First time poster here. Picked up a super 9 not too long ago and love it so far! I got it with the intention to build up somewhat, more for reasonable pickup than top speed. With the cdi de-restricted it seems to do 80kph just fine which is all that I feel will ever be needed for me. However when doubling up, acceleration suffers unsurprisingly and things get quite sluggish as soon as any inclines are taken on. If there are any others on this forum from vancouver BC or have been here and can relate. My end goal would be able to manage the speed limit up the second narrows bridge (70kph limit) without getting run down by some lifted ford with a hater pipe. For a more general reference id like to be able to do maybe 65kph up a 3-4% incline with around 300lb of people on board. 

With the background out of the way and diving into the question. From what I've read on the forum, an exhaust and some jetting/ variator tuning should get me to where I want to be. I'd love to dive into a 70cc kit but i really don't want to have to think about premixing fuel on top of the oil pump as the storage bay is almost always filled with items which would not like to have 2 stroke oil in or around them. Has anyone successfully ran their bbk with only the stock oil pump? People on other forums sounded very weary of doing it. With the assumption that it would be a bit risky to skip the premix, starting with an exhaust, jet kit and tune will probably be the way I want to go. Has anyone here had any experience with the jiangwayne expansion exhaust. I have heard one rave review on a forum and nothing else whatsoever on them. Seems to be of decent build quality and its a good bit cheaper than something such as a technigas triops. would love to hear some input if anyone had direct (or indirect) experience with the pipe itself. Also if anyone would just so happen to have a used pipe, jets or rollers in the greater vancouver (or maybe bellingham..) area I'd probably be happy to scoop them up pretty quick  ;)

Here is a link to the exhaust if anyone is curious.

Thanks for any help in advance!
