You can do 7k+ on engine oil with ease full synthetic. Same can be said about primary. I use M1 90w140 in gearbox and plan on changing every 25k. Most people never change the gear old on there manual transmission gear boxes or rear ends even past 100k. Long gone are the 3k/3 month oil company scams of the past. Not so long ago conventional oil change recommendations at dealerships were 7500 miles and with modern oils they are back their again. My Honda HRV under my driving conditions gets changed every 7500-8000 miles.

I've been riding Harleys since 1975, I'm on my 4th one. I change my engine oil and primary every 3000 miles and my transmissions and my fork oils every 10k miles.
Drain your primary after just 3000 miles. You'll find the magnetic plug already caked up with clutch materials crud after just 3000 miles.
The manufacturer's extended the mileage intervals for you wear your cars and bikes out sooner forcing you the consumers to buy another. Marketing 101
If you plan on keeping your bike for ten to twenty years. Change your oils more frequently.

I agree with Jamesroadking. We buy a 20000 to 40000 thousand dollar toy and then worry about saving money on an oil change. Come on guys! Change your oil and buy good oil. I wouldn't run my car over 3500 let alone my Harley. Every Harley I've owned the top end starts getting noisy at about 3500 miles.

As it turns out I, follow HD's maintenence schedule, but they (or I) couldn't possibly know or prove it one way or another. The only "proof" required of me is receipts, which only prove the date I purchased oil and filters.

Is anyone doing extended oil changes? For instance 10k on motor oil, 20k and 20k on primary and tranny? Using Amsoil or Mobil 1? Just wondering if any one actually did it and has any results good or bad. Thanks. Harley says 5 15 and 20 with syn 3. Amsoil say 10 on the oil, 10 on the primary and 20 on the tranny if using their engine oil, primary and transmission fluid. Using the 20/50 in all three holes they say 10/30/20.
A quart of oil is roughly $10/qt. Primary and tranny take about a qt each. That's $20 every 5000 miles if you change it then.
If you can't afford that, you don't have ANY reason buying and riding that $25K+ bike. Sell that bike and put the money from the bike sale into your home's maintenance/upgrades...it's an APPRECIATING ASSET, as compared to that DEPRECIATING ASSET you are riding around town.

Not sure that saving money is the reason. It is a reasonable question- Especially for those using synthetic oils, many of which claim a longer change interval.
I use Redline oils, probably one of the spendier options out there, but I still stick to the 5K change interval(10K primary, 20K transmission). If the oil still has life in it, using it longer shouldn't be a problem, I wouldn't think- but to know that you'd have to have your oil analyzed, and that's not exactly cheap.

H-D dino oil every 3000 and the other two holes once a year or every other oil change. Redline in the tranny, Formula+ in the primary.
Being that I was easily able to afford to buy this super-expensive toy, then I can certainly afford to change the fluids whenever I want.
Just me, other opinions will vary.
