Ok I have a trx 450 r I just installed a ct racing pipe with header. A spr metals rev box. 188 ct racing jet. A 50 piolt jet. I have the dyno jet needle on the fourth postion. No air box lid. k&n air filter with prefilter.I live about 1000 feet above sea level a little bit less. My problem is that when i go to rev it out it surges it could rev out alot better than it does. I think its not making a negetive air pressure at high speeds. So im going to put the lid back on half cut outlike the hrc lid. Any help would be awesome to get my r running in tiptop shape. Oh ya the low end right now is amazing. Thanx craig
