CSC TT250 Ebay exhaust installed and high flow foam filter
 

Ebay exhaust installed. Had to weld on a new mounting tab for the muffler and make an indent in the pipe for the clutch actuator. Installed a size 40 pilot jet and added a 42mm foam high flow filter which eliminates the stock air box inlet. Starting this "beast" is easier now with the bigger pilot. I also eliminated the emissions components. I kept the air-box on for now until i can do the trash can mod. Performance and sound from the air filter and exhaust is awesome! There is a definite pull from 5k-7k rpm now (I weigh 170lbs.) I am going to go up one or two sizes on the main jet when I get the correct jets. This kit is available on Amazon https://www.amazon.com/gp/product/B0...iglink28144-20

I bought this carb kit on eBay

but the main jets are the wrong thread type.
The pilot jet was correct though

Currently 50 miles on the odometer and will be switching to T4 15w-40 Rotella soon. Oh and I am breaking in the engine by doing some Hard pulls up to 7000rpm then riding it easy and repeating numerous times. There is no way I can keep the rpms under 5k for 500 miles with the hills here in Maine. Plus the long stretches of 55mph roads.

Man those TT's are good looking bikes. And yeah you need some more fuel on the Main circuit.

Very nice work! looks great.

Sweet !

Disable the air injection. It's hell on muffler packing without a cat to suck it up.
Just plug off the vacuum feed and stuff something in the big rubber hose.

Yes, thanks. I did this already. I plugged the hose that comes off the engine and capped off the inlet at the carb flange. :tup:
