Looking to put together a new top end for my bike to hold me out while I piece together my ground-up 4 mil. I currently have a set of big bore drag ported jugs with stock carbs, and T5’s. I’m interested in sending some stock jugs to redline and getting their playport package along with a set of SLP pipes which I will reuse for the 4 mil. Being that I cannot find a good set of virgin cylinders locally, where can I find a genuine set online for a good price? I know a lot of the “genuine top end replacement cylinders” on eBay are Chinese copies and not as good quality so I need help finding which ones are worth using.
