I checked the main jet on my new-to-me 98 Scrammy. It looked like a 170 hex jet. I thought the stock jet was a 230. I do run at 5000 to 10000 feet, but 170 seems like it would be for 14,000 and above!

Is there any way to check the carb to make sure it's a 34mm? BTW, the plug looks good, not white or anything and the quad runs fine. It looks like a stock pipe and a uni filter.
