I would read up on what you want for porting. The short answer is yes, but there is a much longer answer for sure. Check out the 2 stroke tuners handbook. It helped me a lot to understand the engine and what I want porting to be like.
I also just saw that Treatland has the 70cc vip kit back in stock.
I really want to grab one for my VIP, but it would be a little scary on my mini bike.
