[QUOTE="DEANSFASTWAY, post: 640303, member: 31309"] On a sidenote Id like to say that the Kibblewhite products are good stuff . I must have installed about 100 sets of TRX XR400 springs in the last three or four years and NEVER had an issue with them. Ive seen some other brand valve springs on other shops built GSXR liquid cooled drag motors where there springs were so tight you needed a deisel battery to crank the motor over and thats after the plugs were pulled .This unwarranted drag saps power. The motors were built by a big name Superbike shop who shall remain nameless They should have been on a big block chevy .We were worried about breaking the cams so we swapped them out for some looser springs and probably freed up some power. The bikes ran good but the owner ran out of $$$ and soldout .Nestrick it might not be a good idea to run HD springs with the Ti Valves because of risk of pull through or excessive wear on the valve face or keeper slippage. The Ti valves are softer than the stainless intended valves ,maybe Mike Perry or SFO or RICH might have some thoughts on this.Ive seen some 250F Ti valves where the valves almost looked like giant roofing nails The kids were push starting the bike for awhile after they got tight. Maybe I can send pics to Rich and he can post . [/QUOTE]
