05 Motofino 49cc to 150cc

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







and my helper with her safety glasses on

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








And my "cowl hood" that im working on installing lol

Looks good, hopefully it all holds up.

Love that hood!

Thanks Mike... I hope so too!! I had the heat turned up pretty high when I was welding this time lol

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]

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]

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

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...

Congrats!
