Should I get a cam, or get the carb bored out? I am on a budget and are looking for the best bang for my buck.

Best bang for the buck is the bored carb in my opinion.

Ive had 2 bored 43mm carbs and they were both really finicky and hard to keep the idle and part throttle mixtures right (I asked for help from JD Jetting and he sent me a needle that did help some- but he said that the big bore carbs are hard to tune).  However, I am now using a 41mm carb off a dirtbike and love it.  So I suspect if you bore it, stay with 41-42mm and you should be happy.

I have used the 833 cam and loved it.  Great power and nice over-rev power but remember that the 525 doesn't care for being ran at high revs for very long or you'll be replacing main bearings.  Maybe the 806 would be better in the long run.

I am with both these guys a 41.5mm carb is the sweet spot. The one 525 I had with a cam had the rod bearing go out. The other 3 with stock cams outlasted me and are still all running today. If you still want more rev after the bored carb a cam will get you there.

I  say cam first!!! Just the increase in sure volume the cam can make will surprise you!  A good choice on the  stock piston would be , 8/06 it's what should have came in the motor to begin with!  Then bore the carb! After seeing the results on the sea/land dyno and the seat of pants dyno, the cam should be first! But hey I don't know shit! Just my 2 cent worth!!
