redryder Posted February 21, 2007 Share Posted February 21, 2007 Since acquiring my 02 RT in 05, I have always done my own maintanence; including TB synchs. After listening to the well argued (on both sides) of the manometer/TwinMax debate, I decided to go with the TwinMax. Some of you may recall that my first TB synch was an utter and complete failure resulting in me fargin' my bike up so bad that it wouldn't even start. Ken H., a man with the patience of Job, helped me get it going again in just two easy days. (A side note for any of you about to do your first TB synch: the 1100 and the 1150 are NOT the same, and if you do a 0=0 on an 1150, you will spend a few nights howling at the moon and will be called a complete idiot by a few on this forum) After Ken H.(did I mention that he was a saint????? )got me going again I finished off a very meticulous TB synch with my brand new TwinMax. Since that time, I have had a wonderfully surge free 1150 single spark. Since I can't ride right now, I have taken the opportunity, with Red102's assistance, to give Artie a very thourough physical. With TwinMax in hand, I gave Artie another thourough synch. Taking him out for a much, much too short test ride, I found that the surging was back . Hooking up Red102's TwinMax, I found that mine is off by a significant margin. Does anyone know of a way to recalibrate a TwinMax? It will zero out, and playing with the sensitivity knob does cause needle deflection, but the box appears to be off calibration now. So, it looks like a manometer is on the horizon. Now for the manometer question. I know Ken and several others prefer water manometers. My nephew has a mercury manometer. I haven't used one myself, but I don't want something thats going to bounce around and fluctuate wildly from the vacuum surges. But at the same time, I don't want something that is going to be so viscous that it won't show the slight changes needed to make the surge go away. So, at the risk of getting a lengthy battle started, what do you good folks use in your manometers?? Water, oil, trasmission fluid, mercury, beer (no wait, that's what you put in YOU before the synch isn't it?)? Link to comment
