I write here as I need some advice with my problem that the scooter is dangerously slow when pulling away from a start / stop or after i've slowed down to a very low speed (very sharp turn for example).
The bike is a Vespa LX 50 2009. 4V
I have just installed a new variator, rollers, belt and clutch spring. It's a MALOSSI Multivar 2000. It came with a clutch spring so I put that in too. But I didn't put in a new clutch.
Now the result is that when I pull away on flat ground it is so slow that in traffic it is extremely dangerous.
On flat ground it struggles for about 40 metres, then it kicks in and then it goes superb! I can get 75kph now, where as before I was getting 55 - 60. So it the new variator has made a massive difference.
If I start at the bottom of a hill, it takes ages to kick in depending on the ascent.I worry if it will make it up long steep climbs. But if I have speed up already, it's races uphill.
I gave the carb a good clean out before installing the variator. And also yesterday tried resetting the float in different positions, but haven't seem to improve it's pull away.
Would it be related to the clutch?
It's the original clutch and the engine has done 27,000k.
I will take out the carb and clean it again, but it runs so well once the speed is up that it doesn't seem to add up to me that it's a fuel line problem. It doesn't cut out or splutter when I slow off the acceleration.
Thanks in advance for any help.
