Re: New gixxer owner with questions
Oil cooled GSXR's don't have a separate regulator / rectifier - it's built into the alternator.
You can see the alternator from the left hand side of the motor , - Held on with 3 long bolts, behind the barrels above the sprocket cover . Some race bikes may be set up to run 'total loss' i.e no alternator / charging circuit - just a small battery to provide the sparks , until the battery runs out and then no spark . If this is the case with yours, the alternator will be missing and a blanking plug ( about 4" dia.) will be fitted to the cases.
If you have got an alternator fitted - it may be the built in reg/rec that is the problem . It is possible to bypass the faulty 'built in' unit and use an external one off another bike to do the trick. This will entail more modifications to the wiring loom and to be honest , the easiest thing would be to source a replacement alternator.
The pictures of your wiring loom show that it has been really heavily hacked about - few of the connector blocks are original and the 'fuse box' looks like something off a tractor . The best thing you can do here ( especially if you are new to bikes) is to rip it out and get a replacement loom . Any of the 1st gen looms ( 750 & 1100 ) will pretty much drop straight in with little hassle.
If your bike is a US model , then it would have originally came with CV carbs , Euro & Jap 1st gen 750's came with flatslides ( although they were VM29 carbs and pretty similar to the aftermarket RS series carbs)
I'd definitely recommend that you get your red R by donating to the site , this will allow you to browse the oil cooled classifieds and is a great source for any parts that you may need.
