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.
