I think the TT runs a 520 chain, different carb, rubber rear hub, as well as different sprockets.

I got my exhaust this week, put it on , and it is definately lean.I can feel it while riding,sorta surging and if i reach down and pull on the choke it clears right up and runs strong.I ordered a complete set of stock jets (should be here next week) and i will goto the shop and drill em out one size and try them(we have orfice bits at the shop)I will shim the needle as well.
From what you have read , do you think the secondary carbs main jet needs any adjustment? or just leave it as is?What do you think on its opening timing?

As to jetting, my XT350 usually had eight disks in a Supertrapp and always had a drilled out airbox. My plug did not look right until we went with one size larger main jet in both carbs. It also gained a nice little punch off idle by going up one on the pilot jet and closing the airscrew a bit. I can't remember how much.
This was in the 80's and the Yamadealer had all the jets in stock. You can't get to the airscrew until you drill out a plug under the carb. And my standard warning - DO NOT BEND THE FLOAT when you open the carb. It takes a special tool or hours of trial and error to reset the float height. On that miserable POS of a carb the float height is set with the carb ASSEMBLED. God only knows why.

My '86 XT350 was adjusted to have the secondary carb start opening sooner. I think the linkage was adjusted to start immediately. I wish I had copied all my notes before I eBayed my carbs and shop manual. After three years my memory is going. And the guy that did mine really did it right so I tried to share. If you search on my user name for XT350 and jetting as far back as you can go and compare it to now hopefully it won't show Alzheimer's setting in.
So just for the record, my bike was bored twice over and had a higher compression Wiseco forged piston. Plus the air box was wide open and it was running a Supertrapp with 8 disks - sometimes 6 for more grunt. It was geared one tooth higher at the countershaft and STILL pulled hard until the CDI cut out. So I tended to rev the pee out of it. In other words, all that extra fuel may not be needed for a relatively stock engine or easier use.
