clutch slipping?

bigbellyracing said:

Hey guys. I have an 07 Classic that I bought last year with 1300 miles on it. Over the winter I installed D&D exhasut, power commander, pod filter mod, GI pro, removed secondaries. The bike runs great and pulls like crazy. The one thing that I have noticed is that in the higher gears like 3rd and 4th when I let the RPM's drop and I start to accelerate hard it sounds like the clutch is slipping. With the unmolested condition of the bike and the low miles I would not think it would have a clutch issue already. I wasn't sure if maybe the engine characteristics with the secondaries removed would make sound as if the clutch was slipping. I can kind of compare it to a Yamaha vmax when the v-boost kicks in. I may just be going crazy. Any thoughts would be appreciated. Thanks guys!

I use Rotella t6 5w-40. You can get it at Walmart. Before that I used Amsoil.

To bigbelly, I'm trying to find out myself about the question of oil. Trying to find the recommended oil by Triumph, Castrol 10 W 50 or even Lucas 10 W 50, both JASO MA2 approved, is almost impossible at any of the farm stores, auto stores or motorcycle stores close to me. I have about decided to go the the Mobil distributor 28 miles from me and get get both 4T 10 W 40 racing Mobil oil, and 20 W 50 V-twin oil and blend them together to come up with a concoction of 15 W 45 JASO MA2 oil. Anyone have any input on this idea?
