I've usually found OEM to be the best pads...unless you need something very specific (track,trials etc.)


+1, that's what I find, no problem with OEM pads and they don't eat your discs like the EBC ones.

They are OK until you need to change the fork oil. A centre stand (although I know some people don't like them) is still the best option for all maintenance jobs and on the plus side, you have always got it with you.


+1,yes ,a centre stand is the best,I do not see any problem to put one on ,is all ways there when you need it.

With moto engines, the exhaust valves tend to run tight over time. I've found this to be the case on all motorcycles I have owned over 30 years. The intakes, once seated, usually do not require adjustment very often. The heat and beat cycles from the opening and closing of the valves cause the valves and seats to recede into the head. I don't know if that is due to the head being aluminum or what the deal is. I'm sure the exhaust valves running hot helps speed the process. I have run into burnt valves on other motorcycles due to the exhaust valves being too tight and ran that way for too long. I've even seen valve heads broken off the stems. That equaled to a blown engine of course.

Most of the parts in the valve train are hardened and rarely show any significant wear. Because of the high RPM nature of moto engines, the valve springs are really stiff and have a lot of closing pressure to prevent valve float and maintain the seal. Some motorcycle engines do not have valve seats and instead, have the valve seat cut directly into the head. I'm sure this contributes to the receding valve problem. I'm not sure if the CB-X has this or not. I haven't been that far inside the engine yet. I could look in my service manual but it's not with me. Very few motorcycle engines have hydraulic tappets or lifters. The ones that I know of that do have them are the Honda V fours. Those engines are really smooth and deliver the power in a nice curve that would get me into lots of trouble.

I've found that auto engine valve trains to wear and the hardened valve seats to hold their position which leads to sloppy tolerances over time unless the lifters are hydraulic, which most vehicles have had since the '60s. I did have a solid lift cam in an AMC 304 that I built to a 307 that was in my '74 Jeep CJ-5. It required frequent valve adjustments, usually lose.

I was an ASE auto tech from '93 to '00. I started Suspension Techniques in '93 while in high school and later sold out in '95. I started working on motos when I was a boy. My father passed when I was young and I had no one around to help me keep them running. I dabbled in motos until my early 30's when I started doing some moto work for friends. That's mostly what I do now. Other than that, I hold a certificate in industrial mechanics and of all things a cert in bicycle mechanics.


Top post,10/10,I have all ways found valves go tight after time.
