Well Josh, all I am saying is that to heavy of weights will cause that. And since you have a A9 high rev cam and 8 gram weights that may be to heavy and the motor is trying to make more rpms but the heavier weight have caused the belt to climb to early and that will cause the rpms to drop, then start to climb and will drop again and it repeats until the motor catchs up with it.

I agree with you " about the weights being to heavy but I guess it all depends on the variator also " and I'm curious why it just started happening in the past week . Just anothoer possibility and why now maybe the motor is just breaking in and making more rpms. Oh and as far as the report to admins I will let JR and or Jerry respond you would not like my response..lol. Alleyoop |

I deleted the report. I would say all is on the right track and all seem to agree to disagree. I applaud Alley for his patience and keeping this thread on track and geh3333 for working toward making this thread a good base of knowledge and realizing it's just a difference of opinion.

JR That's why I sent the report so the whole stupid Sh-t would stop , I didn't want to respond to his trying to demean what I know ." Childish acts " but since he decided to post about the report I guess it dosent matter does it . That's why someone who can't work with others shouldn't be in control of keeping the peace . Again a very childish act alley . Even when someone tries to help you post ignorant Sh-t . I'm not goin anywhere alley . |

I posted what I said because I felt like that the post Alley made that gave in your report was a difference in opinion, not demeaning at all.
If from idle you open the throttle it should rev right up and SHOULD not loose any rpms, if it does your setup is wrong.
Your problem has nothing to do with your clutch and that already has been mentioned by Rockynv someone who knows how the cvt works.
Alleyoop
I also mentioned in my way your opinion was valued also and it seemed that all had learned to agree to disagree. So let's leave it at that and move on.
JR
A difference in opinion is one thing , do you think it would help ou if I started posting to take the advise of " so and so " because he actually knows what he's talkin about right after alley post ? You and I know what he is saying . Yes an opinion but an ignorant post meant to p-ss someon off . |

That is correct, notice he has a A9 high rev cam and 8 gram weights which in my opinion are to heavy and to heavy of weights will cause the rpms to drop then pick up and may repeat, that is why I asked the question. Maybe to help the troops out I should write up a topic of how a cvt works and what each part does and if one part is not working right what it will cause. Alleyoop That only happens when you hit inclines. This change is sudden, it literally sounds like i'm driving a stick and just upshifted. Or like i just let off the throttle a little. Specifically it sounds as if there is a sudden reduction in gas in the a/f mix causing it to run lean and loose power I put back in the 7g sliders when the problem first started, I had soo much power and it revved so high before and the 8 grams leveled everything out. Anything lower than 6.5 and I loose accel, top speed and waste gas on unnecessarily high rpms The engine had been broken in for awhile now. I ride this thing city to city daily The problem started over a period on 1-1.5 weeks gradually getting worse. I know what the problem is. When the bike gets to a curtain rpm the diaphragm gets sucked down. just can't figure out why yet. Never got around to working on it today. I just remembered I checked and cleaned the variator since the problem started and everything was fine. One way I tested this is by physically looking at it get sucked down while revving and removing it completely and doing a wot run. It no longer sounds like its switching into a higher gear and keeps accelerating. Only problem is there is no gas cut off and it quickly floods as soon as it idles. |

I don't know what's going on with the posting, the post I made that you quoted is gone? Maybe I need to see if our server host is having issues but at least you saw my post and it's still here in the quote.
As I said it's time to move on and see if the OP problem can be solved.

Then it is like I said back a few pages ago, the diaphragm is not holding the pressure it is leaking and dropping the needle. Then it builds up the pressure again and it lifts the needle all the way out again, very common when they have a little leak. If it was a big rip it would not raise the needle out very far and you would get this happening at much lower mph. To test it you need to wipe the cylinder dry then fold the rubber creating a saucer out of it and tilt it and pour just enough gas so that it covers the rubber and the plastic holder by that area. Then see if the cylinder gets wet from gas in that spot and repeat until you checked all around the diaphragm. The other thing is check if the cap is actually sealing the diaphragm.  |

It no longer sounds like its switching into a higher gear and keeps accelerating. Only problem is there is no gas cut off and it quickly floods as soon as it idles. Ok so we are getting back to the #1 suspect of diaphragm now. The diaphragm reacts to the vacuum differential on either side of the carb and at WOT starts to close to prevent going to 0 inches of intake vacuum. That ability to automatically compensate for vacuum drop at open throttle is what makes a slide carb the next best thing to fuel injection. You may need to check anything that can cause reduced intake vacuum like your intake for leaks, failing vacuum lines and your valve clearances along with really scrutinize the diaphragm for signs that it had slipped out of place or has any leaks in it. It may have just lost its seal where it mates to the slide and is pressed altogether which would not make for a very visible leak. Alley's leak-down test is a good way to check for that. Continue playing Dick Tracey (famous comic strip detective for you younger folks) and you'll get to the root cause. |

I really don't know to say it any plainer.The diaphragm gets sucked in. Not falls back into place.Sucked in, like I see the rubber creator into the carb for a split sec, then rise back to its normal shape. I've tries 3 other diaphragms, same thing. I just bought another carb, I'll test and reply back

Have you checked the valves ? The exhaust valve may be to tight
