275R main jet?

[Evan]

I have been searching and reading where alot of people with big bores have jets smaller than 200 mains but I have a 275 pv and I am at 200 and its running better and better each time i increase it so is my motor odd or are alot of people running really lean?

There are lots of variables to consider. Temperature, elevation, size of the carb, porting, airbox or open filter, type of fuel. This list goes on. What works for your setup may not work for another. If what your doing is making it better, keep doing it till it's right.

All bikes are going to be different my 350 ( actually a 340 got shafted by ESR) is running a 210 main, my buddies 350 is running a 238 main, my 310 runs a 180 and my 250 runs a 185 main. I usaully fatten it up until it misses and then start tuning from there.
