Top end overhaul

Tore this one down quite a while ago and finally had time to put it back together. I ended up waiting the longest for the machine shop to finish up with the cylinder which needed to be resleeved. The owner had a friend rebuild it previously who forgot to put one piston pin circlip on... caused huge damage to the cylinder wall but still ran. Burned oil like crazy. ![20170926_113231.jpg](https://steemitimages.com/DQmZiLeYYjGR4bPrALjQSXA282qZMPnveSRpR4acU3qifzM/20170926_113231.jpg) ![20170927_114106.jpg](https://steemitimages.com/DQmWjwVHiiFv2ZZLE2Sh63jPRtTVb1UQ4V7WXcSHCwZUGFY/20170927_114106.jpg) ![20170927_114218.jpg](https://steemitimages.com/DQmfTb66dJ7KvCsjvPZvcqYKibfqsnYZrSMznzhzhboqKNq/20170927_114218.jpg) ![20170927_114250.jpg](https://steemitimages.com/DQmbKTK3nDKNtXvt5JAkvWch57TqRdyJAwV37fLyyAPqGJ5/20170927_114250.jpg) ![20170927_114321.jpg](https://steemitimages.com/DQmQWCtiPEMVafCLHZxUfYvyMiCE6NgLehJ3ATjmr1TEH4t/20170927_114321.jpg)

Now the pretty new parts

It took a long time to find a sleeve for this cylinder and then the machine shop ruined the first one and I had to track down another one... There was serious carbon buildup on the valve train and whoever rebuilt it last time used an extreme amount of blue silicone... I hate silicone. ![20180430_215917.jpg](https://steemitimages.com/DQmRcrs4iCCjRpzbdGNp3ioUREkNRHEtAEnoDEqK6yo3Ef3/20180430_215917.jpg) ![20180430_220024.jpg](https://steemitimages.com/DQmTAMduzsbbqNp9FTejbXkehr8sv3FJ1rCqrff2fQLiKi4/20180430_220024.jpg) ![20180430_221513.jpg](https://steemitimages.com/DQmVuzhbXhDmYyAkAp9q7a4a7a3oqddHZkaRxKQFXzsnUQL/20180430_221513.jpg) I'm a huge fan of Wiseco piston kits, price is good, good quality and gasket kits always fit. ![20180430_223026.jpg](https://steemitimages.com/DQmcqn1Lb3o9MBDA2yzx9zRXzXnjSPTvgdXr35VRyCxQjrq/20180430_223026.jpg) ![20180430_231756.jpg](https://steemitimages.com/DQmcNyRMcGFJV8CCxsbeLngaFJGXDiB2ruCF1vize8owhCQ/20180430_231756.jpg) ![20180430_232309.jpg](https://steemitimages.com/DQmexfLJ6VjVftUmj49nPefcpES74qwEJJW9wnXAYd6vTqG/20180430_232309.jpg) ![20180501_000330.jpg](https://steemitimages.com/DQmWTc5GHkJgHeRhNg58xoppFrhKNPivfZV5mjG2qbi7FQK/20180501_000330.jpg) Its always hard to decide where to draw the line on older machines with when to fix it or let it die. This one could easily become a money pit for the owner if he isn't careful. I went with only fixing the necessities to keep it running smoothly. ![20180501_010215.jpg](https://steemitimages.com/DQmXxvqtzweptbkDWc14RdmZHXBoL26enXcVyYCymiKdHVo/20180501_010215.jpg) ![20180501_171929.jpg](https://steemitimages.com/DQmevw2FKnKK9QZuapGd7BCktb9SPH4LtGDeV1EzMPbG1xR/20180501_171929.jpg) This one has a lot of cosmetic damage as well from pushing cows around and other such farm chores. ![20180501_171936.jpg](https://steemitimages.com/DQmdhfCS1vA6tAc5Di33N9DdjvAYoh8SYpqc9AEWynCcCvL/20180501_171936.jpg) Thanks for reading through! Hope some of you liked seeing a bit of what goes into a quick top end repair on an ATV. Peace.
