stripped the bike down to its frame going to prep it for paint
my choice is a black base with purple flake mmmmmmmmm

one of my mates said to me to put a 110cc engine how can i widen
the frame to get it to fit any suggestions cheers

The frames way too small and not strong enough for a 110cc............Better off getting a 110cc superbike also.......

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

only reason i asked about a 2nd frame is cause its difficult to buy mini moto frames in the UK so i will doing alot of cutting welding etc so i will be asking aload of questions.

Its gonna be sketchy but it can be done..I dont know how safe its gonna be with all the welding your gonna do to make it fit.....

A side by side 49cc engine complete is gonna be 13 1/2 inches wide from outside of pinion to outside of pullstarter

Most cags are only 5" wide between the frame rails...Youre gonna have to widen the frame to 10-11" wide to fit the side by side carbs n such or finding a place for your feet and balancing will become harsh.....

As we say in ths honda tuning scene, Build what you got. just strengthen the frame like shown above and then just fabricate a further back seat mount for a more comfortable ride.

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".
