I just won an eBay auction of 16x various jets. Most are going to be unusable but included is a 38, 40 and I think 42 idle jet, a 95 and 100 main and a 110 main. The rest are eith way high or way low. For under $10 shipped I really couldnt go wrong. Still need to get an assortment nearer the sizes Im interested but couldnt pass up this deal. Seller posted they were used for his son when he used to race motocross.
