I am wanting to put some aftermarket/mods on my ltz 400 right now i have a full system pipe and k&n filter. I was thinking of putting a cylinder works 435 kit that all you have to do is bolt on or the antha 435 kit thats the same thing and hot cams and rev box. I am wanting to know if these are good choice of mods and if i should do any other mods thanks.

 

very good choice of mods you will be happy with it gonna pull hecka hard 450s will be seeing your tail lite my sons z400 has everything minus big bore and he can run away from stock or mildly build 450s

 

Ok thanks would you go with the 435 kit or would that cause me to have problems on my engine.

 

yeah we are thinking of the 440 kit when ever we wear it out it still runs hard and does not smoke or use oil. all we need is big bore and carb it has ESR full pipe and no air box plus rev box and hot cams.

 

where do you ride at I am guessing not too far from dunes because of your user name

 

Yeah i ride at the dunes but mostly trail and tracks and open field riding. I dont want to be having to fix my ltz so if i dont want to keep fixing it you would say not to go with the 435 kit.

 

If it is installed correctly you will have zero issues with a quality (wiesco, athena, cylinder works) big bore kit. All you have to do is "bolt it on" after removing the valve cover, cam chain tensioner, carb, head pipe, coolant, cams, cylinder head, cylinder, piston and then put it all back together with the new parts. You must also upgrade the valve springs if you plan on getting a rev box (if you don't want to be fixing things).
I wouldn't do it without first getting a pipe, filter, carb and cams,then see if you still think you need the 434kit..

 

its worth it but you need everything else to get the most out of it

 

ok I will prob just kit the 435 kit and hot cams.

 

dont forget a bigger carb! you'll definitely need it with a bb kit and rev box!
