Let me start off by saying how appreciative I am of this website. I purchased a 1988 Vmax a couple weeks back that was in great condition. I've had many questions since my purchase and most have been answered with quick use of the search bar.
I've been riding the bike for a couple weeks now and noticed that I'm not getting the "kick in the pants" at 6000RPM as most of you tout. I decided to make sure that my vboost was actually functioning. The servo cycles upon switching to run, and I pulled the air box to make sure the linkage was all hooked up. I decided to pull the plug on the servo mid cycle so that the vboost was stopped in the open position. Upon starting it I noticed that the idle seemed louder(?) and I actually didn't need to use the choke for a cold start. I took her for a spin and it seemed like there was much more power (I'm assuming the vboost was on the entire time now). I've read that many drive around with the boost on all the time but I just don't like the idea. So now my questions:
1. I'm guessing that I need a new control unit. I looked on the micro-machines website and they have an activator and controller. I'm assuming I need the controller but how do I know if I need the activator?
2. The previous owner told me he thought the tach was broken. In his words "It seems like if you're going 55mph the RPM is at 5500, and if you're going 65mph the RPM is at 6500". I'm just curious, what is your RPM at when you're cruising along at 55mph generally?
Thank you very much in advance, here's a picture of the bike also.
