Started cutting the frame today, the 'half moon' on the side of the frame are so the clutch case clears up and i can remove it without removing the whole engine, I will still weld something there to fill up the gap and reinforce it. ALso cut the front mounts off. Will be welding new ones
First look the engine inside there, nothing welded or stuck, it's just a mockup engine, not the one that will be put in of course
@Irongamer727 Yup, TPR86 kit

@DanRacing You definitely want to run a DTR Engine yeah?
I know you guys are mental for tuning, but you could just use a better engine. If you're going to all this effort.
Rotax Engine, KTM Engine....
@Calum In here we make the DTR engine one of the best out there And i'll be running a 65mm bore with stroker crank by the way

@DanRacing this is exciting I wanted to do this swap as I have both bikes but never would use it
Got around to building the front mounts, trying to get the motor lined up was the hardest.
I'm not a welder or anything close, so don't mind the bad weld looks, they seem strong, will try and reinforce them even more tomorrow.
The motor is finally sitting by itself, again everything is a mockup still, will build the engine when i get the frame done to avoid any metal shards
Ok boys I wasn't happy how the old engine mounts looked, so i went ahead and did stuff right
(Getting my driving license for cars also helped me move around and get more parts and stuff)
I ordered a machining shop to make me some bushings for the swingarm mount on the engine so it all lines up good without any play.
I cut off my previously made engine mounts, fabricated new ones and tached them in place. Tried to line up the engine the best i could on center with the frame.
Engine looks pretty lined up.
Going to check everything after dinner and finish the welds for the mounts

@DanRacing looks a sweet build, I can imagine the DT engine to be perfect for a light frame like a 50cc, nice torque and good cruising
@Glynn123 This bike with all the supermotard wheels, suspension and frame is about the same weight as the DT125R, that's one of the reasons i went with the swap. Altought with the AM6 engine it was faster than a mostly stock DT125R it wasn't very good for City Riding with internal ignition and such.
The frame is actually sturdier than a DT125R frame from what it seems, alot thicker steel and very big main frame.

@DanRacing I have a 2003 beta rr 50 supermotard and it weighs nothing compared to my DT haha, although the DT is allot nicer cruising engine
