Hey guys, I just picked up a stock MC28. Only mod done to it is the HRC030 card. I was wondering if I need to rejet the bike or should I be ok running it for a month or two as is until I get some new pipes. The bike is running at sea level if that makes a difference

Also, this is my first two stroke street bike. Does any company sell a workshop book (ie hanes)? I want to change the two stroke oil thats in the bike. Should I just pour out whats in the oil reservior and refill it with the new oil (going to run Motul 600)?

Thanks
Pete
