How can I modify my carb for better performance, I thought that I could replace the air filter with one from K&N, but if I do that I may have to adjust the fuel jets? How do I do that? Where do I get them from? Someone out there help me out. More suggestions will be helpful, and some assistance. lol.

The performance with stock carb is fine and it is the only carb I've used in MANY bike builds. Stront, you ask a lot of questions which is ok but it shows you are new to engine operation and theory.

Learn the basics first and then progress to the more advanced stuff.

Can't agree more. After all the fiddling, the stock carb is fine. Just lean it back (as I noted) a tad and you'll be all set.

...yep, I practice what I preach. I have a stock carb on my personal bike. Its a little rich on idle to mid-throttle but works with reliable transitiona and smooth power delivery.

Just find a way to get more air in the engine. It's that simple to get easy horsepower without modding the engine majorly. It also makes the engine louder and sound better.

My stock engine has a cover for the air filter, and it breathes with just two small holes on the bottom, so I removed the cover completely so the filter can breathe wide open. The air filter still sits right over the carb, but out in the open, and it was a VERY good difference. The bike is much faster on take-off now, louder and more powerful sounding!

See if there is a way to flow more air into your intake by making a Ram-Air, or opening or removing the venting to your air filter box so more air can get to your air filter.

Hi StrontiumEthics,
I agree with all the above, get to know the basics first and do a little read up on 2 strokes first. There are a number of things you can modify on these carbys' to make them more efficient, but you do need the right tools and knowhow to do it. Engins need to breath properly to be at their best.
