??? I received some good clutching info from a earlier post on this website,but I need to know if anyone has a good clutching setup for a 98 xc 700 with boost bottles,delta 2 reeds,and PSI twin pipes. I don't know how big of a difference the pipes and such would make in your clutching setup.Another question is if anyone can recomend or discourage shaving the heads and doing some port and polish work to the cylinders. Any help greatly appreciated,I also should mention that my sled has the late style cylinders,I beleive they are 824's if I remember correctly.
