    @stinkwheeler Wow that's mental? You've been running one on your RS with no issues?

    Do what I done to my RS, convert it to kick start 😉

    @calum yea its been fine ... is it easy to convert the 123 engine to kickstart ? Or do you have the 122 engine as id imagine there different and i couldn't get hold of an sp engine or one from the rx ..... i run a extremely ported polini 160 (by mick abby) ... lectron 38 mm carb ... race inner rota with lightened flywheel ( which i also drilled out to make it even lighter ) rave 2 pnematic pv vforce reeds and a tyga stainless pipe

    The hills are alive with the sound of ... braaaap baaaaap 😁

      Probably a custom job with adapters, that engine looks like a 1 off

        @stinkwheeler Oh that's mental. I heard about the lectron carb, any good?

        Yeah I have a rotax 122 engine, still though I thought they were very similar.

        That's pretty crazy spec to be fair.

          @calum err lectron carbs are pretty good to be fair but you have to modifiy or get a custom throttle cable made as the inner cable needs to be longer ... but essentially you have no jets so tuning should be easier.... saying that it took a while to set up but definitely worth it ..... its never missed a beat in the 3 years I've owned it ... the thing with the rs is to run as tight squish as possible im on .8 atm its really quick but i hate the rs ... the side stand is rubbish ..and the lights ... im 6.2 and 30 ... so its also tiny and gives me a bad back 😂

            @stinkwheeler Yeah, fair enough. It's meant for teenagers after all.

            The Polini kits weren't the most reliable of big bore kits, had one before. Bike went mental, but standard seized. I put it down to poorly jetted, but sounds like you've got that covered.

            Brother picked up a Cagiva Raptor the other day, same age as you (little bit shorter) and that's just lovely to ride. I had a quick blast on it, probably about the same height as you, and I thought it was perfectly comfortable. It's basically a naked Cagiva Mito.

                  So what's the actual effects of these inner rotas? Never heard much about them

                    @glynn123 Common on peds.

                    Basically reverse the operation of the flywheel. Instead of spinning a heavy magnet around the stator. Spin the magnet inside the stator.

                    It's more compact and light, but won't generate the same amount of electricity.

                    But a lightweight flywheel isn't really what you want on a daily.

                    For a car, it'll destroy the mains. Makes them really annoying to drive since and bump in the road will cause the engine to spin up to red line. A flywheel is meant to be an energy store, so lightening allow it to spin up, but consequently at a reduction of stored energy.
