spurdy Posted August 14, 2008 Report Share Posted August 14, 2008 ya i can understand that but u got something to show for it lol im just hooped, That's not true! You still have a good set of ported jugs and a 4 mil crank. Your only out a couple hundred bucks for a new top end. (Unless something else is wrong). Just trying to point out the "bright side of things". I went through a couple of sets of pistons on my 4 mil before we got it right also. Sometimes things just work like that. Anything can be fixed, it is just a matter of time and money. Good luck! SP Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted August 15, 2008 Report Share Posted August 15, 2008 why did this happen? this was a brand new topend? i dont get it. Quote Link to comment Share on other sites More sharing options...
TeamRealtreeHD Posted August 15, 2008 Report Share Posted August 15, 2008 Did your piston actually come off the crank rod? That is something I never heard of before... what caused this to happen? Quote Link to comment Share on other sites More sharing options...
J-Madd Posted August 15, 2008 Report Share Posted August 15, 2008 why did this happen? this was a brand new topend? i dont get it. Yeah that^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Quote Link to comment Share on other sites More sharing options...
2strokespirit Posted August 15, 2008 Report Share Posted August 15, 2008 If the piston broke, you will have to split the cases, even the tiniest piece of piston or ring junk can destroy the bearings and rings... Is this a wiseco piston??? Don't they have a limited warrenty? Quote Link to comment Share on other sites More sharing options...
KEVSWS6 Posted August 15, 2008 Report Share Posted August 15, 2008 I'm here to support you. We need to find out why this happened. Sounds like it was lean. Like I wrote in the email, pictures would be great. I can get new pistons out to you but you don't want to just throw it back together without figuring out the problem that caused this. It will just happen again. I have been here with multiple customers. Sorry this happened to you. We can find the problem and fix it. We always do.

tedd1 Posted August 17, 2008 Report Share Posted August 17, 2008 I had the same thing happen to me. I put the cub together and took it out once. Rode about 20 mins and it locked up. Cost to repair was under $200. I did the wrenching myself and I have decided that I did not get the ring gap right. I honed the cylinder and installed the new piston. Everything is good now. I keep the piston with the stuck rings as a paperweight to remind me to not get in hurry and double check everything. Stick with Kevin, he will get up and going in no time at minimal cost. Just be sure you know what went wrong before you put it back together. Rick Quote Link to comment Share on other sites More sharing options...
