Massive frame. How do I mount a predator 212?

[LucasTW]

Hey guys! Just starting to get into gas bike stuff, and looking to do my first build. I have a custom chopper bicycle with a 3 speed jockey shift that my dad made a while back. Looks insanely cool. Needs clean up and paint. The only issue is, the mount from the Death Row 212cc kit will not work, as the frame is way too long. Would I have to use a standard mounting plate like you'd use for go karts?

Or is there some way to alter the stock bracket?

Pics and more pics so people know what's up and can help you better. Got a smart phone?

I'm thinking you could use a "stingray" or "chopper" 2 stroke motor mount on the chopper. Then, attach the four stroke mount to the stingray mount.

That mount is only good as a work stand. Adapting adapters to adapters is never a good idea.

Man if that's your first bike you've got trouble they warn you at Gazbikes it's for experience bike builders they f***ing mean it and they also say Death-row Bikes they f***ing mean it too.
Even experience bike builders die on them like on YouTube after building one said tomorrow I'll make a video on popping wheelies guy never made another video again.
Don't put any gas in it send it back get something else in exchange. Talk to other motor bike companies they went hysterical on explaining the dangers of it.

But a Harley bicycle frame look like it would match rides low has a big V frame at least you can get on it. I could not even get on my bike with it then it has the exhaust right next to ones testicles one could not get on and off without burning your nuts off no matter the precaution.
Even if the bike falls over it will break both your legs.

Would something more like a Predator 79cc be a safer bet? The bike itself is a full steel frame. Fairly heavy. I wouldn't want to go smaller unless I were to modify a 49cc.

When going 212 you need a very sturdy mount. Very basic bolt-ons like gov removed+a carb and exhaust get them to 9+hp, its nuts. If its full steel like you said, I would recommend welding a motor plate to the frame. No dealing with bolts loosening, threads stripping, or TQ moving the plate around and messing with your chain tension/alignment. I'm not a big fan of the death-row/gasbike style mount on anything over 79cc because the bolts can loosen under the TQ and allow the motor to move around or crack the frame once there is some play on the mount.

I have a stretched frame that I decided on welding a square tube across the bottom between the seat post and down tube, then welding a motor plate directly onto that. A couple bucks extra for 4x stainless bolts+nuts and I have a super strong mount that won't ever move for a fraction of the price purchasing one.

The lady a part owner of another bike company said yes it was, but I don't see a hell of a lot of difference on wieght and size.

Took my tape measure out very slim inches in difference I don't have the specs on it but you can compare, if you half to have predator I would say go with the 79cc
I want something with gut too but I don't wanna splatter mine out out on the road.
Good luck.

Just to let you know inspector can be a little out there. He means well.

Best bet is to post some pictures. Plenty of experience around to help.
