I always look forward to your videos! Build looks awesome. Seems like a lot of people are having problems with those flame arrestors. Interesting in the Rivas for sure.
Thank you for watching. We sell Jetting kits on our web site. If you order there, please give me all your specs in the notes section of the shopping cart. I need to know what ski, what engine, all engine mods done, what impeller, and elevation where you ride. Fine tuning is something you will need to learn, it is hard to "teach" that on a video. Look up and learn about piston wash.
