Losing acceleration and general lack of power
Just started my 3rd season with the 2012 Vstrom Adv. Love the bike but am having some performance issues since I passed about 18,000 kms. That lovely, linear power up through the rpm's and gears has disappeared. Replaced with a lot of engine noise. It's not engine knock, the bike just got louder, sounds like an exhaust leak but no one can find one) The bike feels like it is hesitating when rolling on the throttle in the lower gears but picks up nicely at about 5500-6000 rpms. Above 5000, the bike seems fine with plenty of power but below 5000, it just seems to be all noise.
I had it to a very good mechanic after I took it out of winter storage. He did all the usual stuff, oil change, plugs, air filter, new front tire, adj. the valves and basically gave it the "once over." I didn't really notice a big difference except for the gas mileage which seems to be much better since I had the work done. But the same noise and lack of power in the lower gears\rpms.
I am beginning to wonder if I just got used to the 650 and need more power but I don't think so. I also thought maybe this is normal as the mileage is put on the bike but I don't think so. I am at a loss for what to try next and would love to hear from others about their aging vstrom. I had a short ride on a 2004 vstrom (with about 46,000km) and it blew my bike out of the water in the lower rpms\gears. No comparison could be made, the 2004 had sooooo much more low end power.
When I first got the bike, I would occasionally be in the wrong gear but the bike still drove fine. Now, If I am in 3rd and should be in 2nd, the bike barely goes anywhere until I downshift. In the past that was seldom an issue. With 2 up, as expected, the power loss is worse.
Thanks guys....and Help?????
