Dynojet jet kits increase horsepower, improve throttle response, smooths out powerbands and in many cases improve gas mileage as well. Since most carbureted motorcycles, dirt bikes and even ATVs have to pass some type of smog test by the manufacturer, they can be 'choked up' stock and a jet kit is just the answer to breathe more life into your ride...
Carb Jets...again?
OK, so I've put the pipe on the bike and immediately felt the difference in the midrange. But not being satisfied, I put the K&N clamp-ons on, removing the stock airbox. I only had the take the bike half way down my street to tell I was way too lean. My buddy says I can install the jet kit myself, but the more I look at all the little parts and think about how expensive it will be to replace the carbs if I botch the job, the less confident I feel about it. Especially when Dynojet says you have to sync the carbs and do different adjustments. I thought it would be as easy as unscrewing the stock jets and putting in the bigger ones. Even though I feel comfortable with a wrench in my hand, carbs are a finicky baby. Am I better off trying to find a shop to install them or am I overly worried about nothing? Part of me feels like if they were so difficult to install, why does it seem like everyone has one? How do you know you're dialed in at max performance anyway?
If you can't follow through, you shouldn't be modifying things.
If you botch the job, you're likelier to put a hole in a piston than "wreck the carbs," unless you're really a dolt and cross-thread something.
