mikechief Posted September 10, 2011 Report Posted September 10, 2011 if you have .5 mm plus the thickness of the ring that's about .060" . How thick is your squish ? I would think your piston would smash your head before your rings pop out . Do you have a link for the sleeves you're running ? Quote

I would think your piston would smash your head before your rings pop out . Do you have a link for the sleeves you're running ? thank you dear for replying to my post , i would say squish is about 0.045-0.050 and with the old 4mil motor my piston kissed my head, rings did not pop out i m still useing the same piston for this 10mil motor,i would ask what is link for the sleeves?

mikechief Posted September 10, 2011 Report Posted September 10, 2011 the sleeves aren't stock are they ? Where did you get them ? Quote
banshee9090 Posted September 10, 2011 Author Report Posted September 10, 2011 the sleeves aren't stock are they ? Where did you get them ? it is wsm HEAVY DUTY replacement sleeve i got that from ebay http://cgi.ebay.com/ebaymotors/YAMAHA-BANSHEE-ATV-2-STROKE-PISTON-SLEEVE-HVY-DUTY-/200423423313?pt=Motors_ATV_Parts_Accessories&hash=item2eaa2abd51 Quote
mikechief Posted September 10, 2011 Report Posted September 10, 2011 ebay says your sleeves were stock porting . Did you change anything ? How does it run ? Quote
banshee9090 Posted September 10, 2011 Author Report Posted September 10, 2011 (edited) ebay says your sleeves were stock porting . Did you change anything ? How does it run ? yeah i only lined up the bottom of the ports with the top of the piston at BDC i did not touch the top of the ports due to timing is 199*/130* so the motor running great and strong but i m worry with high rpm and temperature the rings might pop out i do not know if accident waiting to happen.

tedd1 Posted September 10, 2011 Report Posted September 10, 2011 how thick is your base gasket in these pics? If you are worried about the top ring, run a thicker base gasket or a spacer to get a clearance you are comfortable with it. Quote

If you are worried about the top ring, run a thicker base gasket or a spacer to get a clearance you are comfortable with it. yes dear my base gasket right now is 1mm, that is good way you suggested ,i m going to run another 0.5mm stander base gasket so the squish will be 0.059 do you think it is good squish for pump gas or i have to replace the dooms?
