I took a week off of riding to fiddle with my '08 V. The changes made a noticeable improvement in the performance of the bike.
This is what I did:
- Replaced the stock air filter, that had been over oiled by the dealer, and was dirty, with a new BMC filter (a K&N type clone)
- Removed the airbox snorkels
- Put in new spark plugs
- Replaced the worn, over size (by 1 tooth) CS sprocket with a new stock one
- [Last year I replaced the muffler with a Yoshi 2 outlet muffler]
While riding to work this morning on I-43, I was doing about 80 mph (indicated) on a straight, flat section of road, and whacked the throttle open. In no time at all I was doing 120, and had to let off while still accelerating, as I caught up to the traffic ahead. I've ridden that stretch of road many times in the past, and never got that kind of acceleration or speed in that short amount of time or distance.
It sounds a little "raw" with the snorkels out, and the low end/mid range response feels a bit raw too. But the 6k to 8k rush is fun!
After I run most of the fuel out of the tank, I will see what happens with the snorkels put back in.
