nice Dr_C

I had to do the same to put a groove in the top surface of my liner for a guitar string.

I'm curious if you found any contact between the big end OD and the cases and how much clearance seems to be necessary.


do we have the same problem Bergsmlerg ? .. that bastarto who steals the firecrackers must be the same one
Thanks from Dr_C

The very same! A real pain sometimes but hes the only one working for free in this project. Otherwise I would have canned him long time ago...

On old drag racing trick! I use a fabric thread in this engine to keep compression on the head gasket, to prevent coolant from leaking! Very "high tech"!

No contact at all! I think I had about 0,5-1,0 mm clearance. Can't check that until my liner is back from... "honing"?

firecracker fuse is best

re. the FI - very interesting!, so do I get this right, the sensor on the cam is all the timing data that the ECU gets for ignition and fueling? at any rate the fi must have been fun to solve, very interesting to think about at least

Yes, one trigger for both fuel and ignition on the cam (well, same rev at least). That means no wasted spark (higher energy available, less power consumtion). Flip side could be less accurate ignition on low revs (varying speed during one cycle), but I do not operate much in that region...

!interesting! ... thanks

Maybe this is all covered in the previous thread? I skimmed but didn't find info - but I wanted to ask what sensors you have?

I'm doing a gedankenexperiment on updating my DR-Z to 2000's EFI technology

I purchased most of the equipment and sensors from MegaSquirt | Engine Management System | Electronic Fuel Injection - DIYAutoTune.com
That's one safe way of ensuring everything works together. The cam sensor is a normal Hall effect sensor, which I bought from: https://www.elfa.se/elfa3~se_sv/elfa...0-38&toc=19236

How would you suggest I connect my coolers? Parallel/in series, flow direction?
