I did some research on how to use an electric pump and keep the pressure low. Then I remember what I learned when I worked in industry and we used a pressure rupture disc that protected our pumps too much discharge pressure, especially positive discharge pumps. The rupture disc was mounted on a...

That’s a safe level of ZDDP. When it comes to zinc levels, too much can cause excessive wear which is the exact opposite of what zinc is supposed to do.

My FH580V has 1,418 hours and is 19 years old. It starts and runs great with zero oil usage or smoking. Just to satisfy my curiosity, I checked the compression too and got 125 and 126 psi so I would say you have a healthy engine.

Right. When using an anti seize, it is recommended to reduce the torque setting by 30%. So, as an example 30lbs/ft would be 21ft/lbs. There are different anti seize compounds such as graphite, copper, nickel etc. so it’s advisable to choose the correct compound for the application.

I installed this kit on my relative’s Hustler’s FR691. Fit was perfect. If I have this engine, I would install this kit for engine longevity.

From my experience, the valve lash check/adjustment can often be the root cause of many problems., especially if the valves have never been checked or adjusted after about 30 hours of engine run time. Valves will need a relatively short time to ‘seat in’ and then require a precise adjustment...

That’s right. Not only the cylinder was damaged, you can expect the lower end to have excessive wear. Personally, I avoid mixing new parts with old parts. Never ends well.

I would add a recommendation that since the oil changes have been so drastically neglected to change as recommended above and then do another change after about 15 hours to flush out contaminants and sludge and then change every 30 hours thereafter with good quality full synthetic 10w30 or...

My Kawasaki FH580 is 19 years old and has 1,408 hours on the meter. I have changed the oil/filter every 30-35 hours. With a couple of simple mods to the engine, it runs stronger than new with no oil usage or leaks. Take it for what it’s worth. BTY, I checked the compression 3 months ago ...

BTW, back to the FH580 engine, part of the maintenance that I did while setting the governor, I removed the housing to clean the engine cooling fins and discovered that the breather cover was leaking oil which made a big mess. I pulled the flywheel and gave it a thorough cleaning of the magnets...

Thanks. It was a great learning experience and boosted my confidence in doing the cam timing that was not factory stock. Before starting the engine, I checked and rechecked my work 4 times because I kept doubting whether I had the cams timed. Once I kept getting the same results, I went with my...

I remember the pet rock stupid fad. I wondered at that time why didn’t people just go out and pick up a rock anywhere instead of paying for one?

Unfortunately, our society has evolved into a more unethical one. My feeling is that your customer only cares about getting a new expensive mower on your back.

Yep. I have a background in motocross racing and always performed all repairs, maintenance, and modifications on my own machines. I also have a Suzuki Vstrom 650 with cams from a SV650. Same basic engine but the SV is tuned for more midrange/higher RPM power. After researching the SV cam lobe...

As another note, when I did this , I also checked and adjusted the valve lash. Over the years, I have checked/adjusted the valve lash to a slightly loose .004” (snug .005”). 3 valves had not changed in 150 hours of run time. One exhaust valve was at a snug .006” so, being the picky guy I am, I...
