yes i had to cut and notch the frame to get it to fit on roadmaster,i since had bought a new bike a scwhinn del mar cruiser and put my engine kit on that. dont use the roadmaster sx sport or a next avalon.
its a very tight fit,dont do it,not worth it. use another bike if you can.
sparkplug/boot,intake/carb and air cleaner does not fit.

the engine will fit on the bike,its a tight fit thou.
#1 you will need to make or buy a curved or short intake for your carb.
#2 you might not be able to use stock airfilter,tie foam filter over carb.
#3 you will need a short sparkplug and you will have very little room if at all for the sparkplug cap. Goodluck.
do you have a cruiser bike or anything that might fit the engine,it dont have to be a v-frame as long as theres room for a engine.

dude i just took out my dad's bike from the shed and it is the older version and the frame is even biger than the new one
I just did a Roadmaster install. It was a real pain. Wish I would have read this thread before building it. It did turn out sweet though. I had to grind out the engine mounts so it would set lower in the v frame. If I had the right tools to grind out the brackets properly, I would make this a regular build.

My neighbor and I both have Roadmasters. Stripped down they sit on the sides of our house we used them for parts. He got his for $50 and I paid $60. Who knows someday maybe we will do something with the frames.

you maybe could have turned your head around and face the plug forward,but anyway you did a great job and got it to fit.
here is a link to my new bike with the same dualstart engine that was on my roadmaster:

Hey Cab,
Your right!! I wish I would have know that.. ARRGG.. Now I'm wondering if I would have done that, would I have even needed to grind out the motor mounts at all.. I will diffidently check into this and let you all know. This is a nice build other then that so I might be back to working again with this bike. Can't beat the price of $85 for new bikes with front fork shocks at Wally World.
Thanks,
Tony

Hey All,
Roadmaster install updates. I'm going on my third install on the Roadmaster SX from Walmart. This bike is like the best build if you got the 50cc Grubee slant head motor that has the carb mount right to the motor. The front sprocket gear shifter has to come off.
i use the two bolts that come with the kit, that are used if you are drilling a hole in the frame, and used them for the front engine mount studs. They are longer. Just cut off the heads of the bolts. You also need longer bolts for mounting the ignition coil. And of course you need to do the trick of turning the head around so the sparkplg fits under the down pipe as cabinfever1977 mentioned. The break pads do wear down fast so you need to stay on top of them. I also do a little trick for mounting the chain guard. Starting from the back end, I fold down the cover up, and squeeze it in flat, with a vice, just past the rear down bar. It fits perfect this way. No extra parts needed for mounting it. I also install the dual handle break on my installs that you get from sickbikeparts.com. I wouldn't built a bike without them. As someone mentioned in here, it's now how fast you you can go, it's how fast you can stop that counts.. lol
