sheerider11 Posted January 5, 2015 Report Share Posted January 5, 2015 Did you measure your cylinders?? Was the bore true? Was it an egg shape? Was your ring gap correct? Did you do a leakdown? Did you pressure test the cooling side? Just putting in new pistons isn't going to do a thing. It was probably a waste and I personally wouldn't run those pistons unless checked by a competent builder. Quote Link to comment Share on other sites More sharing options...

bpomps215 Posted January 5, 2015 Author Report Share Posted January 5, 2015 Nevermind i found how to pressure test it, i did not measure the cylinders but they did not look like an egg shape the ring gap was correct, i just need to know were to start now Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted January 5, 2015 Report Share Posted January 5, 2015 Leak down test and pressure test. And of course they looked fine. You'll never see .030 out of round. There is 6 measurements to take and then some quick math. A cylinder is bored to the piston as well. So a builder will measure the piston and then bore accordingly to the clearances for that specific piston. I will say, a good builder will. A dealer will just bore to what seems like what ever is on the machine last. Quote Link to comment Share on other sites More sharing options...

Larry's Shee Posted January 6, 2015 Report Share Posted January 6, 2015 What was ring end gap? Have the cyls measured properly, 6 spots, top, middle, bottom, front to back and side to side. Measure pistons and calculate clearance. If out of spec bore and new pistons. Leakdown test before teardown would have told of bad head gasket. Then after assembly to ensure no leaks.

sheerider11 Posted January 6, 2015 Report Share Posted January 6, 2015 Im just going to bring the quad to my local motorsports repair shop im getting fed up and rather just pay to have it done Sent from my iPhone using Tapatalk your not listening. You fucked up. It happens. follow this list 1. leak down test 2. pressure test rad/cooling system 3. disassemble top end 4. send top end to a builder to get you what you need. pay them 5. reassemble top end 6. pressure test rad/cooling system 7. leak down test 8. ride you cant just slam new pistons in and say it has a rebuilt top end. do some research and learn what/why/how shit works and what is needed 1 Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted January 6, 2015 Report Share Posted January 6, 2015 Whee r u from dealer is not the best option, most dealers have no clue.

bpomps215 Posted January 18, 2015 Author Report Share Posted January 18, 2015 Finnaly found what was wrong with the shee, turns out the cylinders were bored 30 over by the previous owner who told me they were stock, so i had put stock pistons in, now im redoing the top end with the right pistons and a good cylinder honing Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
