I had a couple I bought on eBay. Then I sold them on eBay. You can't trust sellers to always know the application. I finally figured them out so I could inform bidders as to what they were bidding on. You have to run a tall air filter to have the clearence so you don't limit air to the carb. I think I read 1 1/2" or more. If you are running a 3" tall filter like I was, it just won't work.
