LCW Posted January 31, 2014 Report Share Posted January 31, 2014 So girl bought a bike from a buddy, who happened to have got it from another guy. The bike was a 4mil on gas with a Herr Jugs motor in it. Well my buddy got the bike and trashed the trans day one. I ended up putting an override in it for him and all was good even on gas. He rode it for a while then decided to go to alky. I hooked him up with some carbs and put some new domes in. I dialed it in and he ran it for a while. He got tired of it and then my girl decided she needed it. She bought it in the back end of the summer so it didn't see much run time. We decided it needed a good cleaning and pulled the motor to proceed. As cleaning went on I decided to pull the intake to polish it up. Upon pulling the intakes I decided to have a look in the cylinders. One has some decent scoring and the other has no hatching. Soo, it's time for a rebuild! Here are some pictures for everyone to check out. Turns out it has the infamous 29L/R rods on a wang crank. Oh, and the guy that had it before my buddy decided to port the piston windows himself. Maybe that's why not even a year and a half later it needs completely rebuilt. Scored up side piston. Note the awesome port job.. This piston actually almost looks worse than the scored side piston. Note where the burr got away from the ported and chewed up the piston. Scored cylinder. Other cylinder. Exhaust side of scored piston.

LCW Posted January 31, 2014 Author Report Share Posted January 31, 2014 Yeah, that crank is coming out. Anyone want to buy it from me? All it needs is new rods.. Quote Link to comment Share on other sites More sharing options...
LCW Posted February 2, 2014 Author Report Share Posted February 2, 2014 Not really any updates as of now, not sure what path we want to go down. I know I'll probably keep it a 4mil. Since these stock jugs are at 66mm, I might fondle the idea of going to a cub. In the mean time going to get the bike apart and ready for powder!

Deadbeat Posted February 2, 2014 Report Share Posted February 2, 2014 so what brand of pistons are those that can take such a big port cut into them without breaking apart, just out of interest.. Quote Link to comment Share on other sites More sharing options...
LCW Posted February 2, 2014 Author Report Share Posted February 2, 2014 They are just a set of 795 Wisecos. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted February 2, 2014 Report Share Posted February 2, 2014 Those windows add how much power ???????????????? Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted February 2, 2014 Report Share Posted February 2, 2014 Honestly, those windows are a bit large but in a purpose built every trick in the book motor..... They are good for about 1 to 2 HP. Not really worth it. Quote Link to comment Share on other sites More sharing options...
LCW Posted February 2, 2014 Author Report Share Posted February 2, 2014 I refunded him his money. The crank is not totally junk, it was pulled from a running bike. As far as using it for a new build I would not. He mistakenly comprehended that the crank was in perfect shape, when in fact it's not in perfect shape. If you have anymore questions about the situation feel free to contact me. Quote Link to comment Share on other sites More sharing options...
camatv Posted February 2, 2014 Report Share Posted February 2, 2014 whoops.. that motor obviously ate a lot of dirt.. Quote Link to comment Share on other sites More sharing options...
LCW Posted February 2, 2014 Author Report Share Posted February 2, 2014 Actually cam, my buddy that owned it before had some issues with blowing the centers out of plugs. Don't know if it was a bad batch or what. I think that some porcelain was the culprit on this instance. Quote Link to comment Share on other sites More sharing options...
