Any interest in cams?

Cams are officially in. But now I need to button everything back up, which won’t happen tonight because I am going to spend some time with my wife.

Sorry for the delay and long time. putting these in – I am just being super anal about everything!! Well that plus work, house stuff, life, etc.

Since I am the first to do this I literally had no idea if the lobes were going to clear the cam caps, clear the cylinder head valleys, if the valve springs were going to bind, if the valves were going to contact the pistons, etc. (still possible at high RPM) fingers crossed.

But the biggest delay was simply adjusting the valves and having to purchase new shims several times and wait for them to be shipped.

I initially bought a kit from hot cams which I have used before on my last project which was putting in a retail premade hot cam brand performance cam in an ATV I owned and I also used their shim kit for that engine- sold almost a decade ago now.

But that was a single cylinder LTZ 400, same motor as the DRZ and KlX 400.

I quickly discovered when doing these reground cams on a 16 valve engine I needed more variety than the kit provided.

The factory Honda shims come in essentially half steps from what the hot cams kit offers. So I found myself wanting to be closer than the kit allowed me to be.

Although the kit will get you in spec, again I am being anal.

Also the kit only has a few shims of each size, and I found myself needing many of some sizes.

So I ended up adjusting with the kit first putting everything together, remeasuring, taking it back apart, reshim, reassemble, remeasure, disassemble and reshim, reassemble remeasure, order shims, disassemble reshim, assemble, remeasure, disassemble, order new shims, install etc.

Having fun yet?

If anyone decides to do these cams after I finish – just make sure that your mechanic has plenty of shims in the 2.00 through 2.10 mm sizes.
