Hi
I have a 1997 Raider 1100. Last year i took off one of my waterboxes. it has 2 waterboxes and i thought taking one off will increase my performance. i also rejeted the carbs with a 80 low and 120 high jets. it ran lean and then when i tried to adjust it ran rich. So I went back to my stock settings and to the 75 low and 107.5 high jets . Thats what it came with. My problem is that the compression dropped from 138 PSi to 130 PSI. When i was messing with the exhaust and the jetting the thing ran bad. I couldnt get the speedo to read over 60 or 61 MPh where before i messed with it It read a constant 69 to 71. I did minimal mods. I went to a pre mix ( didnt like the injection) and i had the head milled, because when it was brand new the compression was very uneven from one cylinder to another. I also had the prop repitched to a 17 21 pitch. i added some older ocean pro flame arrestors and thats about it for the mods. I had it radared at a high of 63 mph even though the speedo read 68. I also have another strange thing happening. If i take all the spark plugs out and crank the motor it cranks fine. if i try to put the compression gauge on a cylinder to get a reading the motor cranks a few times and the starter spins like the bendix is not pushing itself to the flywheel. If i put the other 2 spark plugs on, the starter works and i get a reading. Could you help me or am i a candidate for a new motor soon. i tried to maintain it really well, but I unfortunatley let my friend mess with it.
Thank you
Rob
