Frame mods from 50 to 150 frame.

[oldsman]

I am doing the opposite what others do. I am putting a 50cc on a 150 frame. I wanted the look of the 150cc gator but the plastics will not work on the 50cc. So I am putting the 50cc on the 150. I have talked to the dmv and if I show my work and can show its a 50cc then I can register it as a 50cc and not need the MC license and insurance. This is the look I want.

This is the 50cc frame mount that I have to weld onto the 150 frame.

This is the 150 frame that I have to put the 50 mount on. I will need to remove upright stand in order to have the clearance for the exhaust.

Here is a couple of pics of what I am dealing with. The one with the brass looking pipe is for mock up. I am going to use 1.25' pvc pipe and mock it up that way. It is cheaper that way and easier to do. I hope to have it mocked up tomorrow  and be ready to weld up the real one. I was going to add a few degrees to the rake but it will interfere with the plastic mounting. I will have the frame blasted when I am done with the welding and have it powder coated. Plastics will be painted metallic black/metallic silver when I am all completed.
Shock location (150 closest)
 





It may not seem like alot of work but it has to be aligned perfect so it will roll true. I plan on duel shocks but a 50cc swing arm is not easy to find. So I am going to mod the 150 swing arm to work. I am also going to make a mount for a surprise I am going to add. I'm not going to say what it is so be sure to keep up with this to see what it is.

Interesting project. I'm staying tuned to see how it goes and what the surprise is.

One thing to ensure is that your 50 cc engine doesnt excede your max speed and max hp kaw before you have it reregistered as a 50 cc

I think i broke them rules already. They just want to make sure its a 50cc. Well it is but thats another story.

[jmkjr72]

That may make it so they wont let you register it as a 50
The state may check to see if it excedes the top.speed allowed or check the hp

[oldsman]

Let them Its a 50cc. If they want to check the speed then Let them. I have plenty of worn out belts lol

And six months down the road when you get pickec up and aressted for riding an improperly registered bike withno endoresment becuase you were going faster then allowed on a 50 dont complain about leo enforcing the laws

Here we sometimes change the serials for 50cc ones... I know it's not legal that much but police does this to Chinese scooter/atv/etc. which came without papers or serials. Like, if you have a 50cc engine and a frame with no tag, they give you a 50cc tag. They put a plate with a serial number and give you the slips for the bike. So people used to take out 90cc frame tag and put 50cc one instead to register it as a scooter and not as motorcycle, or for the people like you who used 50cc engine on 90cc+ frame. Like my friend's TGB 125cc which was converted to a 50cc 2T (piaggio I think) because frame is larger and more comfortable on road than the 50cc one and he had pain finding the right parts for the 125cc.

I have been working on the legal issue of this before I go to all the work of doing it and then the say no dice. I was told that they could do it if I have the highway patrol inspect it when im done. I want to know before hand. I have it mostly mocked up with PVC pipe so I can get it right and if it dont fit the pvc is cheap and easy. I have been working on my new handsome boy this week. Quicker to get it running.
