new pistons for 96 gtx 787 where???

[siko]

i need to import all the parts for my gtx since the dealer here in iceland is to dumb to have anything in stock and they are also charging 200% more than if i would import my self...

so where is the best plase to find a personal and good service company that does not over charge on shipping and has a good prize??:agree:

please give me some links or if u are dealers here i need a set of pistons
for my motor i assaebled it few days ago but the compression is too low it is only 100 psi so i am gonna update them...

on top of them i could read 0.50 is that some kind of over size or??

Yeah the .50 is .50 over sized.
Try these, not sure bout the shipping though.

If you go to that large over size, you will need to rework the rave valves. The max is .010" and no problems...You could use out "Parts" link too for parts at the top of the page. The parts sales also keeps out site up and running. They are real fair price too.

hi thanx for quick response...

the current pistons are a 0.50 oversize then....
and the rave valves should be already modded for that size...

the previus owner bougt an motor from i think http://www.jetskihaven.com/

that susposed to be rebuilt but it ran for like two gas tanks thean the ballast bearing shatterd and broke the lower case of the motor i bougt it in that condition..

so i took it and used the other broken motor that came with it for parts the two halves of the lower case...

but i was not so impressed with the compression so i am going to replace the pistons and the rings....

it seems to me this 0.50 number on top of the piston is i deed oversize number the piston is 82.5mm..

Stock in the parts book is 82.00 and over size is 82.25
Part Number for the 1) piston and ring set is listed as 290 887 301 but might have been updated since the original number was issued.
