Guys, I have just finished a craigslist blaster find that was missing the whole top end among other things. It was stock. I had a right side bend pipe and silencer from a blaster I had long ago so I cleaned it up and out that on. I also ported a new eBay cylinder per Ken's YouTube raising the exhaust port 1 mm. It has new boyesen power reeds and a no toil filter with no lid. I started with a 280 main and chopped today and was clearly lean. Where do you guys suggest I start now, 300? Thanks.
