Don't know about the 1500's splines, but I would assume they are similar to the 750. Watch out for the plastic oil pump gear though. it was replaced with steel in 2000 or 2001. The plastic ones have a very high failure rate, and it requires splitting the cases to replace. If it fails, you will need another engine, or a complete rebuild.
Most bikes need their splines lubed, but the 750 seems to require it to be done way to often. I wouldn't have a problem with it if it only needed to be done every 50,000 miles or so, but 10,000 miles is ridiculous. My former Goldwing 1200 did not require the rear splines to be lubed, the shaft went inside the final drive gearcase, and the splines were lubricated by final drive gear oil. There was an oil seal on the gear case, just like on a car transmission. But the front splines still needed to be lubed, and to get to them you had to remove the gearcase and pull out the driveshaft.
