    First post here hello everyone

    2015 Sinnis Shuttle GY6 150cc

    So I've just put a 150cc kit on my scooter and its given it a bigger power increase than I was expecting, top end has obviously increased quite a bit and 30mph+ it seems to pickup speed quicker but its still fairly sluggish below 30-35mph. Im wanting just a little more top speed and an increase as big as possible in acceleration below 35mph.

    The exhaust I'm planning on ordering is the Toro T1, has anyone used one of these before, or does anyone know if this exhaust would make a change to open air filter beneficial?

    Look at this on eBay http://www.ebay.co.uk/itm/322473254601

    I've been reading about variators and my engine and I'm pretty sure 115mm is the biggest size that will fit and matches the fsn casing perfectly. I've been looking at this Naraku "Racing Variator" I believe it is 115mm and comes with lighter rollers than stock so I'm pretty sure this will help a lot along with a longer belt. But again has anyone got experience with this variator or the Naraku clutch?

    Last thing is the carb, the part I know the least about. Will I need to get bigger jets now the engine is 150cc and I'd there any size recommended for the 150s? And along with all the other things mentioned, would I actually benefit from a bigger than standard carb!

    Very greatful for any help and any advice in roller weights and rollers vs sliders!
