Yes, see here (at least in my area of the states) the highest octane that one can buy is 93?! I know with higher compression that you need to use a higher octane, but I've just been using 87 octane. So, in having said that, I need to start using the better higher octane next tank! I've put the jumpers for my Jag CDI somewhere and can't find? I'm using the it now without any jumpers at all. I've found that the engine runs best without any of the jumpers.
So, Fabian, are you saying that you think I should not drill holes in piston, and just maybe bevel the top of piston for intakes? Uno, the main concern I have about the bevels, is the amount of pressure duration they can take over time? See, one would think that you would need to be very careful, because that's where all of the compression load is directed. I'll get reed valve this weekend, and just install as normal and see what happens?! I'm like you in really just wanting the low end torque, not being so interested with the highs. One thing though that I keep on hearing is that the new reed valve isn't a bolt on fix of torque?
With the link you sent, they say that one needs to use the NGK 8...................I've only been using the NGK 6. I just wonder how much a cooler plug would really help with the high compression heat on engine?
