hi all can any one tell me what is the best maker for hi comp. piston 11.5:1 that i can us it in the stock engien with out changing the stock bore and im thinking of the RWR piston for 240 $ any info needed and do i have to install valve springs and titanium returner and do i have to install a cdi for it and what all of you think a bout the cdi whech one is the best .

 

I would say that the Woods is a good one, Pami is a good choice also. I think that DuneMe may have a Pami 11.1 available, not sure though.

You don't have to change the CDI but I would highly suggest it. I would go with the Woods or Pami CDI

 

i have the woods piston and like it i can still run pump gas when just running with the kids. but i talked to gary at tvi and he has a few pistons to choose from. the springs don't have to be changed, but you might want to get a copper head gasket from tvi, if you want to do it later, stock head gasket was $48, the copper is $40 and i'm told you can use it again.

 

do i have to go for a biger carb or just stay with the stock one and what a bout the valve springs do i have to change it ?

 

you won't have to change any of that other stuff, you might want to later

 

what do you think guys does it worth to change it to a biger piston i only ride it for a long jurnys and some drag races and im not a fan of the engien mods and im a fread that will dameg the engien in the futuer

 

In my opinion, if you are going to go into the engine, might as well go with piston and cams.

If you just bump the compression up a little with an 11.5 piston you will not feel a huge difference. With piston and cams you will feel a nice jump in performance.

However, with that you will probably need new valve springs, and will want a new cdi to use the new power, and probably a carb.

Just my two cents.

do the cdi first, if you go into the engine , do the cams and springs also, and you might want to port while your there also.
