Covid caught you.After a short break thanks to finally catching Covid i'm back! I've got my 66cc mounted to a new frame, my new crank seals arrived and once the rains stop we'll get to testing some ignition timing - from rotating the stock magnet as far advanced or retarded it'll go on the shaft, then grinding the key a little to get more movement, then I'll fit that fully programmable CDI that I got from aliexpress ($80 isn't too bad for what it can do!) and see if it's worth it.
Now i've got two bike frames, I also want to dyno both bikes at the same time to see what the numbers show. I'm guessing the torque numbers will add, my brother thinks they'll add until the weaker engine drags the stronger one down. FB experts say it'll only show the curve of the strongest engine. What do you think?
my negativity comment wasnt derived from merely from my ebay cnc head post their has been multiple post through out the years in which his comments were belittling and down right rude. And yes Innovation is 100% guess work you take as much information as you can and you fill in the rest with your mind. sooner or later you will find somthing that has never been done. Albert Einstein once said "I never failed I just found a thousand ways it didn't work" why because guessing is a massive part of innovationI didn’t think he was being negative at all. He was telling you the truth. You call yourself an innovator, but the truth is that innovators don’t guess at what they can measure, calculate, or predict. I went on Amazon and found compression testers.
Knowing how much material you want to take off is the way to go. Commendable.I'm glad I didn't go to town porting on mine. From what you have shown a little cutting makes a huge difference. A couple you tub vids does not make a motor specialist, I'm speaking for myself of course.
My last motor just got port matched and the intake ground out a bit and that's all. Runs great, lots of power for 66 cc.
This next one I'm slowly putting together is getting the same treatment plus decking the cylinder and head as the squish is excessive at over 2 mm. I'm trying for just under 1 mm. Also upgraded to a better fitting wrist pin and have yet to make some shims for it.
You must be getting on to farming season where your at. Spring must have sprung and all that.
