Default engine work

So I knew I would have to do a top end rebuild. I took the valve cover off and started into the engine. The engine hadn't run in years so who know what kind of crap was in there. The pistons looked pretty good, dirty ... but good. my compression test was not so good... I think they cam up around 120 per cylinder. Thats way to low. So anyway ... on with the pictures.



Cam chain looks pretty good, and the cams and lobes were all good.



heres a close up of the piston. as you can see it has 0.50 on the piston so that means its been rebuilt before... uuuuuugggggg where am I gonna find 0.50 oversize piston rings.


Wow look how dirty the valves and head is...




The cam towers/barings look great I hope the valves and stems are still good.


exaust and intake buckets all removed and kept in order.



So I pulled the valves ... what a pain in the *** that is with out the right tools. I finally made a spring compressor with an old socket and a C clamp


its took a long time but if finally got the jugs and valves all cleaned up... I also painted the jugs and the head. the valve stems were good and I replaced the valve stem seals ... so lets see what it looks like all together.



So I decided that I couldn't find any oversized rings and pistons so I would just hone it up and see what happens.... stupid ... I know... anyway...





I'm pretty stoked about the way the engine came out ... it just needs a lot of aluminum polishing. I wasn't looking forward to that.


Ok thats enough for tonight... I go in to the frame tomorrow.

Thanks, Matt-
