El Mamito USMC Posted July 1, 2013 Share Posted July 1, 2013 Ok guys the ony things that were added or replaced from my previous build was: new crank, new berings, CP piston 12:5:1 , CRF 450 clutch and CR500 springs. The bike has a lot of power, response and torque , its just that not it doesn't have that "snaping " pull that it used to. The mec said that the clucth its a very smooth engaging one. There's no slipping or nothing. The bike its a lil easier to ride now, like a lil more civilized quad. For begginer purposes. I just would like to know if this has happpened to any one else? Just a dubt , I'm still very happy with it and ready for battle this 4th july weekend Quote http://www.offtopic.forum/data/MetaMirrorCache/06f1a7ba567102d307e3f721efc437ad.jpg Zorros racing.. #123A - Baja 500, 2014 FINISHER !!!

CJM Posted July 1, 2013 Share Posted July 1, 2013 Possible jetting issue? Never heard of this sorta thing unless you change a cam or go up alot in compression on the piston. I will say that my 400ex when I added a 04-05 450R carb and I went to 426 on it caused me to shift my power around. Bigbore+better carb imho. I had to go for more speed on my back sprocket (drop teeth) b/c 1st and 2nd and to a degree 3rd came to quick. Is the above whats going on mamito?

CJM Posted July 2, 2013 Share Posted July 2, 2013 Very strange, more seat time is needed for sure to know what it is. Quote 04R work in progress Link to comment Share on other sites More sharing options...
Immortal ATV Posted July 3, 2013 Share Posted July 3, 2013 Only thing I can think is you are losing compression or the rings are still seating.....other than that maybe add a tooth to the rear.
