if it ran perfectly good, just turn that exhaust cam back one tooth & go for it!
we'e all had the same trouble, just be accurate in what you do & it will all work out fine.

There is spark firing mark as well so make sure you line up the staight line.
With WR timing the left mark on the exhaust cam and the right mark on the inlet cam should line up with the gasket surface of the head. With YZ timing the right mark on both cams should line up with the gasket surface so you should just turn the exhaust cam 1 tooth clockwise.
As for jetting with YZ timing try the standard DRQ needle in the 2nd clip position from the top( 2 leaner than standard) and a 45 pilot, 170 main with the fuel screw about 2 turns out. Adjust the fuel screw to suit conditions. You may need to adjust jetting slightly depending on your exhaust and altitude but this should put you in the ballpark.

MJ first, then needle. don't change the PJ if your happy with it. i was recommended 48 & used it coz 'they said so' gone back to 45 & it's lovely.
