I was browsing the puch kits out of curiosity, and noticed they had a kit/head for $120. 7cc, after taking a closer look it looks to be a k star kit.. Is this a blaster kit with all high end, I read in the 50cc threads that the 50cc kstars are blasters. im not looking for a race bike, I just prefer the sound and feel of 70cc. Is this kit going to have some decent bottom end?
