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...............

This type of frame would be a better choice for your type of project.......Its plenty wide enough,,has a place for a jackshaft setup and just needs a solid mount swingarm added

Youre gonna need a diff frame unless you like doing alot of cutting,,bending ,, welding and grinding..Without making a jig its gonna be a lil difficult keeping the frame square and even and keep it from warping from the heat of the welder..............Even the rectangular steel isnt too cheap compared to square tube and isnt easy to bend either without kinking the rectangular tubing........square tubing is way easier to bend without a mandrel tubing bender............

I already have a twin engined pocketbike and am in the process of making a triple engined bike and was thinking a triple double setup would be the shiz til i found out how much the build was gonna be in the end.........I cant condone spending $4 grand to build a triple deuce pocketbike from scratch.....

It cost me only $30 bucks to build this one.............



This is my triple engine dragbike frame...........

Anything is possible but it will take alot of mods. First I would want to lengthen the front section rect. rails, then add some lower rails up to the neck and neck braces. Then lengthen the rear arms. You can use 3/4" x 1 1/2" rectangle tubing, cut the rear arms in half, and slide the the new tubing over the stock arms and run a round 1" tube up from the rear part of the arms to the upper frame. See the tubing I got for my Cag to Polini water cooled bike. The alum is for my avatar Lucky 7 to move the rear arms back 4".
