thats what i said mate going to with a 49cc twin how would i go about making the frame wider or increase its length ?
You need a welder and rectangular shaped steel that matches what ya got.......
Id start out with either an X1 frame or an x7 frame..........Theyre both wide enough and long enough and is easier to mod the way you want....,
To widen the bike youre gonna have to split the bike in half by cutting the tubes from the neck,, add longer tubes towards the neck and bend them til the frame is widened,,,after that you need to weld in supports and the engine mount....After widening the frame and swingarm youre gonna notice the rear tire looks out of place and wont line up to the engine so a jackshaft is gonna be needed.............
I had a cag with a similar frame...I strengthened it to fit a KTM50sx engine but have opted for a sick and hairy methanol /alky powered dual carbbed 54cc engine...............
