I need to find out how many teeth the intermediate shaft on a newish, well late '09 aerox has. I would just whip it off and check like I know someone will tell me to do but unfortunately I don't have and gear oil and need to use my ped everyday for work and shit so can't afford to take it off the road for more than an evening! Any advice would be great. And what would be better, primary or secondary? The bikes over revving at top end like I though it might lol Cheers
