Well another update - I stuck the scooter on blocks and revved it, no belt slippage on either belts which is good news.....but the rpms do not seem to increase much from the 3/4 throttle point. Wondering if this is because the engine needs to be broken in a bit, but next step seems to be what a couple of you smart (smaht) fellows eluded to...that being get a Tachometer and check the rpms.
