I have my DS 650 motor apart,needs a cam and a damaged crank bearing,I would like your opinion on tips,clips,ideas,I race desert and stock motor is pretty fast,but faster would be nice!!!maybe able to hit 100mph on straight aways!!!This is a full on BAJA prep quad,elkas,17inches of travel,+3 arms,GPR stabilizer,flexbars,the quad will handle any terrain,reliability is a must!!
Open for suggestions!!!!

 

If your going to rebuild it I would go with a 770 from mr hp or better yet look around and you can find a complete ready to run 770 or 800 motor for less than you can build one
you will want it set up for desert rideing and not a 300' drag motor

 

Before I went full on drag with my DS, I was desert racing a built OMW 730 with an OMW 46 Lectron and it ran flawlessly!

I agree with Ray, if your gonna rebuild and have to get the crank fixed get a stroker.
