01-04 gsxr 1000 stroker
looking for some info for a buddy of mine. hes thinking of building a 3x4 this winter. any of you had expirience with these? Im hearing they dont live very long, but that seems to be the case with every bike when you mention stroker, so im optimistic. hes planning on running some nitrous, nothing radical, probly 30-60 hp
something else that was suggested was just go for the 3mill and put on the 05-06 head as its supposed to be a way better design
opinions?
thx!

If he's going to have it ported, it won't really matter which head he starts with. The 05-06 head uses Ti valves, whereas the 01-04 valves are ferrous.

I haven't heard about a problem with Ti valves and nitrous, but then again, this forum is about my only exposure to such drag-racey things. If heat is the problem, bronze seats should solve it. If you're not going to do a full CNC port job, then the K5 (41G) head's ports and larger intake valves may be better-suited to your application. Of course, our K3 (18G) motor was always fast regardless of cam timing, particularly on top, whereas our 41G motor (prior to Jim's CNC porting) was good in the midrange, but seemed to run out of steam kinda early. I'd probably start with the standard head and only upgrade to a 41G head if you think you're losing out somewhere.
