Hi All, just wanted to post an update for others that look at this post. I have no more oil leaks, the scooter looks nice and clean. Thank goodness it was not the cylinder as I had miss diagnosed where the oil was coming from. At the end the culprit was the missing screw and gasket that goes on top of the chain tensioner. Thank you all for the help

geh3333, thanks for the advice. So I finally was a bit faster then my buddy (barely). He is basically a FBO 150cc with ported head adn slide carb. His scooter seems to be a high RPM screamer. Anyway he did a complete rebuilt of his transmission and now he is wicked faster then me... this is what he got: * NCY Teflon coated Variator * NCY Gen 3 Clutch * Snowflack Clutch Bell * 1500 RPM main clutch spring * NCY aluminum variator face * 10 Gram sliders I was so impressed what a difference this combo made on his scoot, take off and top speed are both higher, but that is not the only story, it is so so smooth... I mean you tap on the gas and that thing just pulls so smooth or you can hammer it and it takes off... I was so impress. here is a pick of the combo...  I already ordered the NCY variator driver face, and the Clutch and the snoflake bell are next on my list.

Man getting this scooter running 100% has been a challenge. My friend who was going to get us connected to the dyno got into an accident so I do not think that is going to happen any more. He is ok, but I am not sure if the wife will let him ride anymore.
Anyway I thought I had the scooter running very good, and now all of the sudden it feels rich after installing the gears? Makes no sense to me... I just know it feels rich. I cant go WOT or it will bog down on me, but if I accelerate gradually to about 1/2 trutle it feels great, when I start going more then that I can feel its getting too much fuel and revs start dropping.
with the side panel off, I thought it was running good (it covers the air filter), so I will have to try again and see, most likely I will have to go back to the 128 Jet... just odd
That said I did go to work today and took the highway all the way in, 30 miles, even running poorly it kept up with the cars, although pockets of traffics were welcome to give her a break... I basically did not go above 1/2 trutle the whole way, still hitting 65+ CMPH

geh3333, I put in a new variator in, however I was wondering what else could be causing the belt to slip? I did put a 1500RPM clutch\torque spring last year which is much tighter than the stock one. For example I cannot press the clutch down by hand, so it is really grabbing onto the belt very very tight. In my head that make sense that it could cause slippage. Should I try a 1k RPM spring? what is your view on this? thank you - Luigi

Everything up to the oil being allover the place sounded to me like a vacuum leak problem. What kind of intake manifold are you using? Make sure spacer between head and intake manifold is not cracked.

Went for a quick ride today my rpm still feel high after gears changed still at 8k rpm.. Is that normal? I thought they would drop some. Put new variator in with everything new. I have 12grams rollers. Considering getting 13gram Dr pulley rollers

Hi All, just want to post an update. I replaced the rear tire which I went from 3.50 -10 to a 100/  10, which is about 1cm wider and 1mm taller. Man I am glad i did not go any more aggressive as it was a very tight fit, but worked perfect. My variator belt broke again so I figure while I was at it I would replaced the gears as well. I took my time and cleaned the whole transmission nicely and out in a brand new variator and weights and replaced the gears. I went from 13\40 to 16\38 (hoca) I got her all back together last night and I went for a very short drive as I want to make sure it does not break down on me or anything, but I was very very impressed with the results. She felt faster on acceleration and on my 1/2 mile test drive it hit 65 CMPH easily. I plan to do more extensive driving this week-end and I hope she can keep on being reliable. I did not change variator weights I will keep it on 12 grams and keep rpm lower. It was dark and could not see rpm, but she felt very fast, even at 50 CMPH, when I floored it I felt a nice pull. |

Hi All, since I need to take my variator apart I figure I would do gears. Anyway I opened up the gear case to see what I am looking at and when I count the gears i am counting 13/39. I thought stock was 14/40 or am I counting wrong?   |

How much room do you have between your rear tire and the back of the engine block? Thanks I'll have to pull a carculator to make sure I am not going too much over  I'll check and let you know how much space I have. |
