I had a little problem with my TE-610 when I started to check my valves. That problem was that I broke off the high pressure FI elbow that is mounted to the baseplate on the fuel tank that holds the PUMP/FILTER, and pickups. I was able to locate a new OEM replacement and in the interium, I decided to check every external nut and bolt on the bike. This was a good thing as I found: Loose upper motor mount bolts-- Which cured my RPM dependant vibration Loose clamps on the throttle body----Which cured a hesitaion simular to a symptom of a bog with the accelerator pump. It also cured my decel pop. Mind you I do have a vince can and had the dealer retune -remap the ECU, but the pop was still there on occasion. Dan at Motoexotica did a top notch job, and in no way was the pop a result of what he did. I also decided to check out my steering stem bearings. To my suprise, the outer reatiner on the bearing is plastic. There was lots of white grease, so I cleaned them, lubed them and reinstalled them. I was not however able to fix my steering stem lock Shameless plug: I also had Cliff at RPS in Shingle Springs, Ca revalve the forks. Even though I did not have the external compression adjusters added, this thing is like it is on rails. I use to bottom the front tire on the fender on a high speed ashpalt turn, not anymore. It also does not have that nasty rebound. Once again, I told him what I wanted, and got exactly what I wanted. I had the time to remove my wheel bearings as the bike was getting new tires installed. To my suprize, there was little to no grease in the suckers. Getting the seal off the bearings was a real treat. So after a cleaning, and re-lube, the bike rolls much better. This would be top priority to check out. The timing chain adjuster was only out 5 clicks. Valves were right in spec. I think next time I am going to use better gaskets as one of the gaskets were leaking... Next the swing arm.... No time to do that, but I did remove the shock and checked to play and ease of movement. Spot on as far as that goes. Mabey I will tear down the rear next....
