If you have a pipe no lid, then you need a minimum of 188 at sealevel. You will also need to adjust your needle to the HRC needle, to get the best performance.

You could also get the Dyno Jet jet kit from an online store and follow the directions they give as a starting point!

i ran the stock pipe with a HRC end cap, and no air box lid...I used a 185 main and left the needle stock....it ran great, and was much faster....this is at 0 to 3000 ft....

I think if you take your baffle/spark arrestor out, take off the air box lid, get a high flow air filter, you can go up to a 185 or 190 and be fine.....
