My 2001 Yamaha Bear Tracker will not start. I have narrowed it down to no spark. I replaced the coil and still nothing. When I was putting the old spark plug boot back on there were 4 pieces that came out when I unscrewed it. A very small flat disk, a small spring, a white cylinder and the gold grabber. I wasn't sure the order of these and don't know if it makes a big deal. I put them back in first the small spring, then the tiny disk. which came out in two pieces one almost the whole disk and just a chip. I put the big piece in and left out the chip. The white cylinder was next and the gold grabber screwed in. Is it the boot or a problem above the coil. Please help. I don't think it is the plug either. The one in the quad isn't brand new but it isn't an antique and I tried the back up plug too.
