check out this website Click its a small comapany out of PA and the owner is great to deal with and will do anytihg to help you out and get your engine running great and the prices are very reasonable, much cheaper then FST or Alba........the CWR BBK + the stroker and you get 450cc's plus the pistons are hi comp i think

 

also dont forget some nice billet ajustable cams or a re grind and lift on your stock cams if you want to save some money

 

in stock form the warrior may be more reliable than a z-400 but do everthing you want to do and the warrior you used know wont be there and the z will be more relaiable with liquid cooling and still put out more power with better suspension to. and with a better resale and the warrior is just to out of date.

 

to me it's going to just come down to what a person really likes to ride,sure the 400 is fast but when i rode my brothers i didn't like the feel of it but i have been ridding my warrior for years.i guess you cold say what ever floats your boat.to me the warrior has never been a racer or anything like that but they are fun to ride.

 

same here, i rode a z400 once, and didn't like the way it felt. I like the firmly planted to the ground feeling that my warrior has. If you're planning on keeping the stock suspension then the z400 would have an advantage, but I plan on replacing my shocks, axle, and a-arms with better aftermarket ones anyways so that doesn't make much of a difference for me. the z400's may be a little better than the warrior's stock shocks, but they still wouldn't be good enough for they way I ride.

 

warriorboy22, I think that you would be more happy if you sold the warrior, and used the money from that and that 1300 for a stroker to buy a raptor. You said that you wanted to be able to ride trails all day and not worry about overheating. Then I think a used raptor would be right for you. For about 3800 you could probably get a 2001 or 2002 that already has a pipe, jet kit, and pro flow filter. Plus the raptor will be faster than the warrior. The low end torque of the raptor is awesome I really think that you would like it if you like to ride trails. I saw the pics of your warrior it is pretty clean and it looks good. it is probably worth alot. I seriously think that you would be more happy with a raptor. Then if you want to go faster with the raptor well they have some potential. I just got mine running and tuned in and it is scary fast.
