You really shouldnt be downshifting to first unless your going to stop either at a light or stop sign or other reason and then you put it in first just before the bike comes to a stop or to neutral and put it in first before you take off. the input shaft of the transmission is spinning too fast at 30 MPH to engage such a small gear without grinding or clunking. I never go to first till the bike is at least down to 5 miles per hour. Theres no reason to go to first at 10 mph, stay in second.
As far as choppy shifts on a vulcan 800, the front sprocket is a 17 tooth. The gearing is just a little too low. Remember this bike is a sport/cruiser. Ever hear how the engine screams when going 60mph? change the front sprocket to an 18 tooth. What a difference in shifting. No more getting seasick. And 60 MPH sounds more like a crusier. It brings the rpms down by about 400 and it dosnt change the takeoff from a light or dead stop. It brings the bike from a sport/crusier to a CRUISER. Like a new bike. Go to www.sprocketspecialists.com
