So, as you can tell by the title I need help. Well here's the details. I started by upgrading my cag 47cc engine and that's all good. Next thing I did was find a complete bike and purchased it great deal ($20) anyways I could not for the life of me tell what kind of frame it is. I'm guessing its an mta3 frame it looks like a gp mx3 to me. Anyways now for the question I have.

All of these 47cc engines has two threaded holes above the clutch bell for the bracket to connect to the frame for added support. What I have realized with the fame I have is that I can't find a good bracket to apply to it. I'm stuck. I attached some photos. its about a 3 in. gap between the connection plate from the frame to the threaded holes for the engine bracket. any help or suggestions will be greatly appreciated!

thanks,
Jon

go to a machine shop they will stamp on out for you. I had the same problem except I had lost my triangle bracket, so I simply cut a piece of sheet steel, marked where the holes were and drilled it. Problem solved.

Those brackets are crap anyways...I use 1/8 -3/16 steel to remake mine then weld them to the frame for extra strength....


That frame you got is so weak...That little upper engine bracket holds the weight of the engine,,torque of the engine aswell the weight of your leg pressure while its being ridden..............

On my thin walled tubing framed trophy cag I added an extra mount on the pullstarter side...

Thanks a lot for your suggestions guys! I guess I could machine a piece of metal.... I have no welding experience though so that sucks but I can imporvise. And that bracket is very important too right? What would the outcome be if I went without an upper bracket?

If you went without the upper bracket theres a possibility of the engine loosening,,,engine plate breaking at the welds and the exhaust loosening up at the headpipe............

Two pieces of L angle and some screws and you can make one like the last cag pic.........I forgot to add that there was limited welding involved with that one and only took 30 mins to whip up and install...................

in most cases, if you can get a few bolts in it, it will be every bit as strong as a weld, especially if you dont have a good weld...LOL i prefer welding simply because i have the tools and the knowledge, but bolts hold just as good...and if your hole is a touch off, you can ream it bigger....cant do that on a welded piece if its a hair off...LOL

If you were to make a cardboard template and mail it to me, I could machine one pretty easily. I own a machine shop full with CNC's and the software to program them.

Be around $40 bucks.

Ied take him up on that offer. I would punch it out on the Vipros with some 12 Ga carbon steel sheet to make it super strong too.
