the CH250 engine is back on the frame

I put the engine back on the frame to start working on the subframe. It needs an offset of 41mm. With the use of templates I'm making a drawing to build the right side swing arm. 
I am using the ComposiMo Yamaha Zuma stretch as a starting point. Credits there.
I'll have to remove some parts of the frame in the back, because I decided to go for a 170mm/ 6.7inch stretch. Pretty long but it can use a serious stretch visually. It will be trial and error to find the right length.

getting somewhere with the CH250 Spacy Elite hub

Today, I did some work on the hub. I made a removable center piece, so you can fit different rims.This one's inside diameter is 62mm.If I want to change it I can change the center ring.I have to find M10 lug bolts, not very common apparently. The second option is to use long M10 press bolts.Or make the holes larger to fit M12 bolts.

The next thing is to fit it on the frame and see what the offset will be.
