I have been looking for a while now for a bore kit, pistons, cam for my 04' Z250. I finally found a cam but no luck with the pistons or bore kit yet. I just want some extra power, the price isn't a problem. I would like to upgrade to a z400 but really don't have the money for it and the 250 my father bought me back in 04 so I don't really have the option of selling it.

I currently have a Yosh Offroad Pipe, K&N filter, and Dynojet jetting. I found the Web Cam at Web Cam's Site but there are 3 choices. I'm thinking the one designed for racing w/ a valve lift of .425 and duration of 288 degrees. If I would get this cam would it be hard on my motor? I'm not going to need to rebuild am I?

Also I would like to purchase a Wiseco high compression piston kit but I cannot find them anywhere. I did find a guy's sale on ebay (a guy from here). It comes w/ a ported head, Wiseco forged piston w/ a ration of 10:1. Is this about as high performance as it gets? And for $175.00 is it a good deal.

Finally I would like to sell my yoshi pipe and get something different. The yosh doesn't seem like it has the compression I want. Its not the RS-3 (i don't think) it only has Offroad on the side. I would like something w/ a big power increase. I'm not worried about how loud it is, I just want the power. I had my eye on 2 pipes so far. Ac Racing's Flow HVO which claims to add 10+ horsepower or Alba Actions slip on exhaust .

Almost forgot... I was looking at Procom Engineering's Aggressive Advance Curve CDI for the 250. It is said to increase 1000 RPM over stock and remaps the timing curves. Procom Engineering Its on their website.

Please let me know what everybody thinks on all of this. And where I should purchase the pistons.

 

dont' be afraid to say anything... wow? lol

 

heres a question why? why mod a 250 4 stroke. why not just trade it in or sell it and get a bigger bike.

 

Id ride the heck outta the 250 you have till its time to trade up to the bigger 400 , then mod it out to were you want it. But hey...thats just my two cents![img]i/expressions/face-icon-small-smile.gif[/img]

 

i said above... my father bought it and gave it to me. but for the fact that he bought it he doesn't want me selling it. (confused yet?) He's not exactly the most reasonable father. The money that I do have I need to save up for a car.

 

He"s resonable enough to buy you a quad....maybe your confused![img]i/expressions/face-icon-small-wink.gif[/img]

 

haha yeh I know I thank him for that now I need everybody on this forums help so I can have my fun :-P

 

i also took notice that four-stroke tech makes a big bore kit for the 250... but I'm guessing to get it installed is going to be pricey.

 

4 the pipe get the dmc alien it gives it alot of power about 5hp for the full system and its about 400 bucks i think and for the cams and the rev box go 4 it

 

yeh i only have like 300 max for exhaust... :-/ thats why i was going w/ either the alba or the Flow... does anybody know the performance of either of them?
