So today I put the engine back together. Installed the valves & had the head milled .090". I have to re-do my exhaust with this "P" head because the flange is clocked differently.

I rehoned the cylinder and gapped my rings to .009" for street use. Lapped my valves and took a straight edge to the cylinder to make sure it is proper.

I love how clean this engine is inside. It looks like it doesnt even have any miles on it. I pray that this one will last!

I will pray with you... Nice work

Thanks Rob!!

Here some pics from tonight. I got my motor mount all ground down and ready to reinforce aka weld.

Also secured my plastics a little bit better. All the wheelies seemed to break just about every tab that held the nose on lol

Hmm.. I think one whole person follows my build... nice lol

Anyways time for sum updates.

I reinforced the motor mount last night with metal from a leaf spring. I sure hope this metal does not tear. I made sure to tie it into both the motormount itself as well as the frame.

Also relocated my muffler, as it use to scrape if I leaned too low before, and the flange on this "P" head is clocked differently. I still dont know if I like the outcome or not. I kinda rushed it because it was getting late and said F it and welded it together!!

Excuse my ugly welds

Yep I must admit, I generally read more than post, but do when I feel the need. Don't worry, MANY are watching and following. ;)

MEAN_MOTOFINO 03-18-2013 06:54 PM

Thanks a lot guys, you are the best!!

And rob there is already a headlight and tail light. The black peice on the front blocks the headlight so its only run in the day time until I figure something out.

Im hopefully going to be breaking this engine in later on tonight if everything goes right. I noticed when I drained the oil that it was that thick weird smelly break in oil that they ship with the new motors, and it was very clean, so I doubt this motor has barely any miles on it. The rollers also look brand new and the drive faces have absolutely no wear on them : )

MEAN_MOTOFINO 03-18-2013 10:02 PM

YES!! I got the scoot running tonight & broke the rings in! :yay:

Its quieter than the other engine...maybe because the muffler is mounted further back but the engine itself is also very quiet with no ticking or knocking whatsoever. Here is a pic of the variator that come off that engine...
