I was just out in St. Anthony Idaho. I just met a guy out there who had a 400 along with his buddy. His friend but in an Edelbrock carb and he apparently smoked him..... he in turn went to a YFZ450 to be competitive against him. I just purchased the carb and installed it, but because I may have a bad valve or ring, I still don't have mine running to test the perfomance. If mine requires a piston/rings I will most likely add the 440 kit to mine. I currently run a Yosi RS-3 complete pipe and a rev box. I'm really hoping that the new carb, which eliminates the need to jetting (rather then tuning the carb) will be a help.

 

is that 470 going to be rebuilt every couple of years?? i was going to get the 434 athena kit then i bought a shee. thats what i would go with. pipe,cams,carb,good port job and you'll be ready to play with the big boys.

someday i'll get off the playground and make it to the stadium!!!

 

sandgod, who has the new lt-450 and raptor 700? is that you or buddah? damn ,your video's rock!!

 

I agree with sandgod on getting what you pay for sometimes. I didn't. (IMO) My first kit was from ct and although it ran better The head was only just sanded and it came back with stock springs. I think if you install a after market cam you should install better then stock springs. My head now was done by a guy I have used for years on all my drag bikes and what a differance. Do your home work before you do anything.

 

Buddah owned the 700r for about 6 months.. He now has the Yoshi 450z and LTR450... Our Athena will beat a 700 Raptor as well as the LTR.. We raced many times and Mr. Athena has never lost.. It's all in the combination of good parts and a guy who can port... Can a Raptor be made faster??? Absolutley!!! Can the LTR be made faster, yup, but for right now the Athena handles the LTR pretty easily..
