Your brain is a national treasure, mine hurts just wondering how much effort you had to put into making this available. Maybe I’ll buy some of your programs and build my grandsons Cobra FWE 50 he’s really fast but is big for 8 yrs and we’re going to Mammoth you can run a 60cc big bore. Wow you’re giving me a lot to ponder 🤔🏁
thanks for the compliment. I think everyone should have my 2 stroke calculators. I first made them for my own use because often the good available calculators were just too expensive.
if balance cannot be achieved 100% it is best to make the motor vibrate in horizontal axis of the motorcycle. much much less noticeable than any vertical. :D
Interesting information but also a large amount........Call me crazy but I don't wanna study 8 hrs a day for the next 6 months to try and get a 100% perfectly balanced motorized bicycle crank. By factoring in things like ring drag, rod length, cylinder pressure,bearing frictional drag,etc... I'm gonna balance it the same way you'd balance a motorcycle wheel. I'll test how it acts on the balancing stand before I drill into the crank to find the heavy spot, then get it to act like a balanced wheel. I was thinking of plugging all the holes with a combination of loosely wadded up aluminum foil & JB weld.... Scuff up the area inside the hole, wad the foil up to where it almost completely fills in the hole, leaving a couple mm space at each end, then add the JB weld, let cure, sand off excess.....I'm thinking the JB weld sticking to both the roughed up crank steel & to the uneven foil inside. Should give it plenty to grip onto & keep it from dislodging.
I think your way is the long way, not mine. With mine you just measure everything and type in the measurements and then keep entering a bigger hole diameter till the result shows balance.
@@MichaelForrestChnl I was in no way trying to criticize you & appreciate the information you supply (unlike some people on the forums) . From a glace, it looks like lots of reading (haven't thoroughly looked into it yet) If you balance a crank with the piston, rings,wrist pin,etc..on it to behave like a balanced motorcycle wheel. Wouldn't it be much more balanced ( much less vibration) than a poorly balanced stock crank?? I see at a quick glance of the spreadsheet, it asks for things like the connecting rod weight,bottom/big hole ID,etc... Which I assume means you'd have to- split the crank open, take rod out, to weight & measure & press back in place,etc... Not sure I have enough/proper tools to do it right now, stuck with a very low budget due to health issues. Still have a welder,MC wheel balancer,small vice, small digital scale, calipers but no press like an arbor press & only one 3 jaw automotive gear puller, no more garage or workshop. Which is why I thought of using a "close enough-much better than stock crank" wheel like balance method.
@@michaelbrinks8089 it's best to take it all apart to weigh the con rod but the total weight can be estimated just by letting the small end of it rest on a weight scale and multiplying that by 2.2, and then just enter the specs of the big end bearing into the calculator and using the estimated bearing weight displayed at E11.
@michael brinks how is your statically balanced crank doing? ive tryin the same thing at the moment, got a 80cc china kit which vibrates so much that two welds on my exhaust broke.

no such thing as 100% balance for a 2 stroke unless it has the extra counter-balance shaft

it's not possible to statically balance a crank. @@roehle9962
Thxs for the excellent video. 0:56
can you use your calculator with bikes equipped with balance shaft ?
yes
Where can I purchase these software?

write in english if you want a response
You need to contact me. I have a theory you need to hear. Thank you.
I'm at 19jaguar75@gmail.com
Have you got one for a vtwin?
no, this is only for single cylinder.
@@MichaelForrestChnl ok thank you. Nice program
