I can buy Shell 80W/90 here in PRC, without too much effort. It's not available everywhere here, but at least one of the stores that I shop at stocks it, so I buy a few tubes of the oil as needed. Currently have 4 tubes sitting on a shelf in my garage. Same as this gear oil sold in bulk via Taobao http://item.taobao.com/item.htm?spm=...id=9229848577&Quote:

Well not quite but nearly..
I got the trans cover off today.
Scoot has around 2.5k miles and I wanted to give the trans an oil change before winter sets in.
The oil I drained out was milky :confused1: is this normal?
Any how, 250ml fresh oil in and I also added 50ml of ZX1 micro oil. I have been using this for years on my cars and I am impressed with the results.
Next oil change for the engine will get similar oil treatment.
While the trans was apart I gave it a good clean with MuckOff degreaser and a hose down, finished of with compressed air.
Tomorrow, weather permitting is a plug change.

No, its not normal Rob. I'd say that there is either water that has got in and mixed with the gear oil or else they have used some odd type of oil which might be possible. Might be worth taking a sample of the oil to your dealer to check. Otherwise, run the new oil for 500-1000 miles and then do another change out. Oh and pay attention to riding through areas that are flooded or where the transmission bathes in water. BTW did you take the variator pulley off and check the condition of the 6 roller weights and the variator ramps (the location where the roller weights sit and slide up and down the "ramp" by centrifugal force as the variator spins) If not it is a good idea to do so, as both the roller weights and the ramps suffer wear. I'd suggest replacing the roller weights with "sliders" which are a wedge type of shape, and likely due to the design to cause much less friction between the surfaces of the slider and the variator ramp and ramp walls.Quote:

AT first this might happen only periodically, but as the mileage increases it will become more frequent. This phenomenon occurs when trying to move off from a standstill, the scoot will be real sluggish as though it is in a higher gear. Once it gets some momentum it might feel as though it changes down a gear and comes right. What is likely happening is that one or more of the roller weights has/is becoming worn and likely scoring out part of the variator ramp wall too. This causes the affected roller weight to get stuck or caught in a fixed position within the variator thus not returning the centre of the variator as it should. The roller weights need to have free movement up and down the variator ramp. The roller weights are constructed from an alloy with a synthetic surface coating which is likely heat and friction resistant, but does wear out over time through use. When this coating is lost or separates exposing the alloy, this causes the alloy to "cut into" the variator alloy surface causing gouging to occur which in turn hinders the movement of the roller weight leading to loss of proper centrifugal movement and impeded functionality.
Just saying..,
I don't think this is an option, the cover is designed in such a way that it is vented. Good idea tho'Quote:

The unfortunate thing in the UK is that Chinese scooters/bikes as only sold through "box movers" there's no service at all, they are assumed to survive the 12 month warranty period and then you are on your own.
I will try and investigate the slider option, as I believe prevention is better than cure.
EDIT - I also swapped out the spark plug for the Iridium variant - I will post on how it performs...

Hi WirralGhostHunter, I have just replaced my 35 watt halogens with 55 watt globes on my Jetmax and I notice the lens gets rather hot. I did not feel the lens with the lower wattage in so I can't compare. I am a bit concerned about the reflector etc being damaged . Can anyone let me know. Regards

Hi ethron, I think I recall bikerdoc doing a similar mod before he went the HID route, and he commented on the wiring getting rather warm, I always refer to his posts before I tackle anything (he's virtually taken his Jetmax apart, so he knows it quite intimately. Because of the crazy laws in the UK, I couldn't chance swapping out for HID's, but I did find some alternatives lamps ( I posted them here ). These give a really bright white light compared the the standard yellow light. Although not HID's, they do a really good job. Perhaps I will try and make a night video to show how the perform....Quote:

The workshop did it last time so maybe they added a little more than they should have - so as I put in exactly 1.5 ltrs, I'll see what comes out at the next change and let you guys know (I've dipped into the oil filters bikerdoc sorted for me :thumbsup:)
The scoot hasn't stalled on me - I give it a little longer to warm up now - and I feel the iridium plug was well worth the change.
I have some more little mods I plan on doing next week, as the days are getting shorter, nights longer and its getting bloody colder too.
The first simple mod is to fit my new handle bar muffs, they wont make my scoot look any more elegant, but even with winter gloves on, my one hour commute each way is making my hands very, very cold....
I have my new stop/tail light to fit as well, I think I have a position sorted out for this (at present my top box shrouds the brake light. I also have some rather smart mini projector LED running lights (these are freaking bright), I still need to work out where to fit these. Any how here's some pics, I will post again when they are all fitted. Ride safe guys..
Cheers WirralGhostHunter for the reply. I should have said the 55watt halogens are not HID. I just love your Stop/Tail idea and what a great spot for it. My LEDs are Stop only and I would like the Tail light to be on the box as well. I may get one of those LED units. I wanted to upgrade the "running lights" which are dull little push fit globes but found the LED clusters will not fit through the lens hole. Same with the amber flashers, a 20watt globe will not fit through the lens holes and I am thinking of getting LED flashers which are mounted each side higher than the 10watt standard flashers. I have just come back from a ride, only about 20 km and the headlight glass was hot. I just wish I had felt the glass after a ride with the standard halogens fitted. I might be a bit paranoid on this but I don't want them to blow or damage the lens. The higher wattage halogens are heaps better showing a whiter light and further beam. Cheers to All
