hello everyone,

I got my vespa 300 gts 2016 used with 10k on the odo.. all maintenance done on time.

I couldn't stand the rattle in the rear clutch, so I thought the hell with it.. got a delta clutch with the bell, and a malossi belt... it was amazing the rattle is 95% gone and no more vibrations at take off, thanks to the harder white clutch springs.

anyway I got a multivar kit, due to everyone saying its night and day. installed the contra spring ( white ) and the variator with 15g rollers (for some reason I didn't get the 16s and the 14s.. but I got the kit for a good price. so I installed it and I DIDNT LIKE the way it accelerates and poor topend.. maybe because of the lighter 15g rollers. I understand that I should get the 16s for the 300gts... but theyre not available atm...

so I removed the variator and contra spring... bike was good .. but not great.. I installed the white contra spring with the stock variator and stock 13.9 rollers. and man.. I think this is the best combo for now..

so my question is.. has anyone done this before and what do you suggest I do next with the rollers or do you suggest I return the stock contra spring? well I did the VARIATOR MARKER TEST. and the belt went all the way up when it was on the middle stand with traction off.. I mean in place... didn't test it on the road..

so I know the contra spring isn't too stiff for the stock rollers...

I heard a lot about the dr pulley sliders.. 13g... does anyone suggest that this is could be the final piece of my clutch puzzle ? or should I go back to my stock spring and install the sliders.. plz share ur thoughts.. thank you!

I wont use anything but sliders in the stock variator. they work amazing. its inexpensive trans tuning at its finest if you ask me.

experimentation works best. if 13 is recommended I would buy 12 and 14s. half of each will give 13. when I tuned my 300 I had the cover off eight or nine times . and in the end 1gram is too much jump and I added 1/2 gram plastic sleeves inside the sliders. but this tuning was done in conjunction with changing fuzzy washer thickness as well.

when I tuned my 500 it was much easier as it has an RPM gauge. so you could see how much rpm was jumping with changes. I bought an RPM gauge for like 10 bucs off ebay. connect to spark plug lead so its very easy to connect. havent tried yet but I want RPM info for future tuning on my 300

if you didnt want to experiment I would recommend 13. they were better all around than stock with no annoyances. 12 was a bit revy but fun.
