so how about it can i use high comp piston for a drz in my z? or how about cams?

 

Yes, they are interchangeable. Add a carb and you will see noticeable power gains.

 

well i found drz cams from wisco p#4714m09000 for around $130 its a 13.5 to 1 its for the drz shows the same bore and stroke as the z 90x62.6 anybody done this yet ? how can i find out the stock cam specs and what the aftermarket cams have ? im not going to do 1 without the other who makes cams? i cant find web cams site and whitebrothers shows they have cams 4 the drz but specs? are the cams for zs going to be ground diff for a quad? building power the old fashion way[img]i/expressions/face-icon-small-smile.gif[/img]

 

The motors are the same as far as these parts go so you can order DRZ parts and expect to acquire the same performance gains.

 

thanks 4 the help if you know any good cam sources let me know thinkink of a carb swap fcr quiksilver how about alchohol?

 

Many places have cams and Trinity is going to have Web make a special grind for the quads. Alcohol burns cooler and makes more power, but it burns more than twice as fast as gas. Unless you are building a drag motor I wouldn't bother.

 

The 400z motor is the same as the DRZ400s but you can use the DRZ400 kick and DRZ400e parts (cams, carb) if you want to get the compression up on the 400z to the DRZ400 spec ( Z 11.1 DRZ 12.1) change the base gasket to the DRZ400 kick gasket. Here is a sight with alot of good info it is a DRZ forum so search for what you want to find out. Http://www.people.ucsc.edu/~mnelson/drz/DRZ400s.htm also check out Thumberracing.com and look at the 470 kit for the 400s that would be great on the 400z.

 

will we be able to run pump gas if you change the gasket? 12:1 is kinda high for 91 octane.

 

The Z400, as it is, is supposed to run on 87. When you up the compression to 12.1:1 you're supposed to be able to run on 92 octane.

I'm wondering if this turns our low end to crap.

 

92? haven't seen that here in california in years. we have 91 here [img]i/expressions/face-icon-small-sad.gif[/img] anyway, as for the low end, wouldn't you think it would improve it?
