GSX-R Has Arrived

October 15th, 2009 by BT Leave a reply »

1989 GSX-R 750L Initial viewCrappy picture…I know.  The GSX-R arrived yesterday.  It’s worse off than I thought, but will surely make a great long term project.

I do have the tank and some of the body work, but it’s not on in this picture.    The back tire is a nice fattie!

So..I’m not sure where to begin with this thing.  I tried jumping the battery just to see if the lights and starter work, but it’s absolutely dead…so obviously a fuse or electrical problem.

All three calipers are frozen as well.

My immediate plan, aside from kind of chilling out for the winter, is to maybe get the calipers off and rebuild them over the winter.  I’ll poke around at the electrical issues, but not much until the spring (my garage is not heated).  The gas tank has no cap so it’s all rusted inside…another good winter task.  There’s really not much I can do I guess until it has a working electrical system and the ability to put fuel into it.

Another good task is cleaning out the carbs.  There is no way they’re not totally gummed up.  Does anyone know how to get the air box off of a 1989 GSX-R 750 so that I can then proceed to get the carbs off?

I almost forgot to mention – the guy told me this was a racing bike before he bought it in 1994.  That seems to be accurate since it has a racing seat, front slick, and little twisted wires through and around most of the bolts.  Supposedly the engine is build and has Wiseco pistons and some other crap and output is (was) around 130+ horsepower.

That’s too much.  If I need to do a top end rebuild, I’ll de-tune it.  I don’t need or want that kind of power.  The stock 102 HP is more than enough.

      I was thinking the same. I’ll just try to get it back to stock. THanks for your advice. I know next to nothing about these, other than they look cool. I like your idea – the airbox will get whacked this weekend. I did determine that the battery cables were just corroded and now I get guage lights and taillights (and some response when I pull the brakes). I agree – it seems like the clutch switch or neutral sensor is whacked.

        I’ve had several 89 gsxr’s and all seem to run best with the stock air box. A tuner told me it has something to do with the sling shot having a shorter stroke motor? Not really sure. I know my current 89 is running a stage 3 jet kit and full Vance and Hines race pipe with K&N filters. It has a small flat spot at low RPM’s that I can never tune out? Good luck with the bike, the old oil coolers never let me down!!!!
