Upgrades: What would you do first?

Seems to me that my problems lie in the area of carberation... I don't trust myself to tune the carb correctly so i guess i will go about finding somebody who is.

My airbox has also been cut open somewhat.. i've used electrical tape to get the hole back to its original size, but i'm still lacking the snorkel. I soppose this may also have something to do with the power issues i'm having.

I would do the R1 brakes first. I had it done to my bike, and my buddy bought a 91 with stock brakes. Same road swapping bikes we were amazed at how much less pull, and more feel came from the brake upgrade. The old brakes felt very wooden. The R1 brakes would save you an easy car length at 50 to 0 with more control.

If you are going to have it dyno tuned open the airbox up. They will be able to make use of the extra air.

Don't modify your airbox. I tried it a while back and did get a small increase in top end performance but midrange suffered big time. The dyno guy I used to test with said the needles were part of the problem with an opened up airbox. In low to middle range it was almost impossible to get the airfuel mixture right across all cylinders.

Recommendation was standard airbox or open (individual) filters. Nothing in between, unless you went for injection and had a big wallet.

Just my 2c

If you're going to upgrade your brakes ... don't overlook installing steel braided brake lines. Makes a big difference.
