Alright my two cents after my front piston overheating which lead to a rebuild and things I do differently and why. I ran 15w-40 t5 back then...
If you use heavier oil and ride hard, you will slowly loose oil through the crank breather. Heavier oil accompanies an increase in oil pressure. So check your oil level somewhat frequently. Especially with 15w/20w multi weights. That lost oil will be in your air intake tube and/or burned.
What I do now is use an inexpensive 10w-40 (Autoquest, but this is regional), 5% Lucas oil stabilizer and a K&N filter. I change the filter once per season, but change the oil once per month (runs me $2.44/qt...so like $7.50/mo). If you wanna use a moto specific oil, try valvoline 10w-40 motorcycle oil. Runs $4.99/qt here. It's about oil change frequency, not synthetic, conventional or even weight really. It's also about price for most us.
*Also make sure it's not energy conserving. This is on the back.
