If you have no idea then the best place to start is Creeper's setup thread, and use Laramie's BST Bible for reference. Then check the usual suspects if you haven't already (start with the battery - even a low battery can be an issue if you don't disconnect/turn off the headlights).

I don't want to do all this just to find out that there is a difference only if you change the jets.

To be clear, I'd like better throttle response and no fresh air in the exhaust....and that is what I expect....am I going to get it...??

Also, all guidelines on changing the base gasket are welcome!!

Cheers!

Since there is one post to the contrary on some points:

Creeper thought the modest slide drilling had merit.

oops, wrong thingie

Creeper thought clipping the spring had no merit.

Creeper thought changing the jets (if necessary) for your altitude had merit.
I am guessing that if the jets are wrong you won't get good results.

Not sure what "fresh air in the exhaust" means...

Links would be fantastic!

Thanks!

I think that is a completely different exhaust from KTM (sparkie vs no sparkie SXC can). Maybe someone makes a sparkie endcap?

OK, one more place to check is down in the "Ask Baldy, Blame _________" forum. Ask for Baldy to get back to you since you might not know who is a mod that has checked with him or not.

For the sxc can,, pull the tailcap and check you should have a turbine type s/a in the center of the muffler and not the tailcap.. Mine was gutted by the previous owner.. If your was gutted get a universal round screen from JC whitney or like the bigdogs one and tac weld it into the tailcap. I was rushed for time and had a brand new sparky add-on s/a for a muffler sitting around. I removed the insert part and made a plate that slipped in behind the tailcap and the s/a screen is welded into that. I have to make a how to thread as it was easy and I took lots of pics.. but i'm better with a welder and wrenched then postin pics..

Thanks I will do just that. You can remove the end cap.

Stay tuned!

Okay? font? what should I change? (yes, i know its a friday night, but I'm home with a sick kid while the wife is at New Moon... What else am I sposed to do!?)
