I've got an 88' with the stock cylinder that has a full race port from Jerry Hall, bored 2nd over, fmf fatty pipe, stock carb, stock reeds, stock bottom end, and stock ignition. I'm wanting to get a little bit more from it on the top end and I'm just not sure where to go. I would like to keep the stock cylinder for now. Running mostly in the dunes so low end is not a huge priority. Any suggestions are appreciated!
