bought a 2009 assault. Ive only been able to get 8050 on top end rpm,changed weights and spring in primary no change. so yesterday i checked the exhaust valve gaskets and they were blown out, so i put the newer style in it out of a 2015 rmk. still same rpm hit 8100 once . i checked the synch on my pcv tps and changed that to match. now the problem is it wants to cut out on bumps. sounds almost like it runs out of gas. any help would be appreciated. thanks
