Engine build question

I come from a family of muscle car lovers. I helped my dad build stockcars for many years. Helped him with his prostreet '68 nova and currently working on his '81 Z28. I also have a few projects of my own. Tearing down and rebuilding these engines is pretty easy (to me). How tough is it to build up a bike motor? I have a 99 gsxr 600 which is my dream bike. I would love to build a 750 for it but is it worth the time and money? Any input helps.

Thanks
 
ok cool. How easy is it to find a decent 750 for it? With it being the last (or second last, i dont remember) year of the carb. motor i'm sure there isn't much left out there with lower KM.

Sorry, i'm new in the bike scene so i dont really know how easy or hard it is to come across original parts.
 
the 750 motors weren't carbed. all SRADs in 750 were fuel injected. that was the generation where they switched over from carbs to FI for the 750 and following 600cc generation got the FI.

if u want a project then go all out and swap in a 1000cc engine. Google it, its been done numerous times.

Actually the SRAD 750 started in 96 I believe and for 96 97 it ws carbed. 98 and 99 got the EFI.

Yes i believe you are correct


Bah, this seems a little more dificult than i thought. I think i'll just stick to building cars and when i'm ready for a bigger bike, I'll just buy bigger.

The skills are transferrable, but the scale is quite different..and all the things you learned about small-blocks aren't quite the same for bike stuff. You need metric tools, lower level torque wrenches, bike machining guys, different techniques. It's not impossible obviously but it would be a learning experience.
 
Also, the reason that one "rebuilds" a small block Chevy is often that the parts supplied from the factory were not high performance parts, and there is a lot left on the table by the factory for improvement.

That's not the case with modern sport bike engines. Yes, in many cases there will be *something* left on the table, but it's small by comparison and the penalties associated with "improvements" will often be much larger (reliability, having to use race fuel, etc), and unless you are building a roadracing bike for a national championship, it isn't worthwhile to go into the engine.

There is no point to rebuild a GSXR600 into a 750. Just buy a 750 and be done with it.
