can u use 2 intake or 2 ex or 1 of each i just got a used z05 going to get a full ex and woundering about cams and a pistion what would be the best for woods riding

There is 1 intake and 1 exhaust cam. Going with hotcams and a piston is a definate performance booster.

Give us a call if you'd like to get some ordered up/.

get the hotcams but don't change the piston unless you need it!! use the drze base gasket on the jug and your compression ratio will be 12:1 with the stock piston! anything higher than that will have to run on race fuel only!! also go ahead and get a did timing chain from paul at advantage cycles, use the drze valve springs and get some kibble white valves. all this will pretty much bullet proof your motor for trail riding and hill climbing!! talk to paul at advantage cycle, he is a site sponsor and sells most of this stuff in a kit form so you have everything you need from the get go!!
