Its not CD185 any more and not a CB250, its a 233cc engine swapped custome cruiser made by my self.
Putting a 250 or a 350 cc engine in cg chasis is insanity and dangerous, it is not an art but madness.. passion what ever you name it.
when I swapped engine I knew that vibration may kill the chasis and I assured by consulting some of the finest magician of maddness Mechnics to have there oopinions about bigger engine vibrations, drawbacks and if cd-185 frame is really capabale enough to incorporate bigger engine power, torque, and vibrations and I came to know it hails from roadMaster family and strong enough and will be no problem in bigger cc engine, besides the difference was only +4~5 hp and results were quite well...
And yes there was no choice left but to put a bigger tyre becuase the engine was just killing a small 3.00-17 tyre but now... both are in perfect harmony, and dics brakes provide good breaking as well..
