rm 85 motor in a Raptor 125?

[exhausted]

Has anyone put an rm 85 motor in a Raptor 125 frame? I am in the process of doing it now ut wohld like to see some pics of engine placement if anyone else has done it successfully.
Main reason we are gonna try the raptor frame over the cobra or jb frame is that my son races his 4 stroke raptor and loves the chassis and the size. He feels too big on the smaller frames.
Anyone tried it?

I think there was one for sale in the classifieds. Haven't seen any in person but shouldn't be real hard to do. Does the raptor motor bolt through the swingarm pivot point or in front of it.

It bolts In front of it. Getting the motor to sit as far back as I want it is being a bit challenging. Where we have it right now has the drive sprocket further in front of the swinger pivot point than I want, but I think we are gonna try it like this anyway and see how it works. If I have to run a tensioner of some sort, so be it. The only other thing I was wondering is if there Is an easy way to e tend the kickstart out to get it to clear the frame of the quad?

On our Mod which is a CR motor in a Pitster frame. It has a roller under the swing arm pivot point. No other type of tensioner. As far as extending your kick starter I cut the part that goes on the motor shaft off and welded it to a short piece of 3/4" od 4130 chromoly tubing and then welded the kick starter to the other end. Also I cut a slit in the tubing to allow it to tighten down on the shaft better..

Awesome. That was we were planning to do, but wanted to make sure there wasn't an easier way first.
