Hello , I'm new to the forum 
...
Now I'm facing a tricky question... I'm determined to get a Micrgi Mustang and put a 49cc or 80cc engine in it, but before I even order it, I need to know one thing so I don't spend a lot of money and find out that it was useless given my current skills in building bikes...
So my question is:
Those of you who have experience building Mustangs - have you ever had to force the rear dropouts (rear wheel mounts) to widen? I'm just wondering if when I put the engine on the frame - will the engine rosette and the rear wheel rosette be flush?? ...
Because it seems to me that the Mustang's dropouts are quite narrow... So I'm really hesitant if it won't happen that the chain won't rub against the rear fork of the frame and if the axis of the engine rosette and the rear wheel rosette will be in the same plane...
And finally - I'm asking because I can't bend the frame and widen the rear fork of the wheel mount and I won't do it either, because I've never done it... if it's necessary to forcibly widen the rear wheel mount so that both rosettes are in the same plane and the chain doesn't rub against the frame - then it doesn't make sense to me and I won't buy it..
With all the other things, such as buying longer cables, buying a longer fuel line, a chain tensioner - I'm familiar with all that, I also know that I'll need 36 spoke wheels for a classic rosette ...
PS: I'm sending the engine I want to put there in a photo - its a classic 49cc / 80cc engine kit
