Aahhh yes just squeezed into the shed and held the chain next to the mini bike.. The quads chain is definitely bigger... Pics attached
So guessing 6mm on bike and 8mm on quad
Yes theres a #25 on the minibike and a TF-8mm on the miniquad.
Just know if you buy another TF-8mm pinion and rear sprocket you can make the pocketbike TF-8mm or the pocketdirtquad to #25 to keep both chainsets the same too.
Theres 3 different types of drive chains they use on pocketbikes , pocket dirtbikes and pocket quads.…Technically theres actually 4..
#25 is like linguini, There s nothing smaller for these pocketbikes
25h is slightly beefier as H stands for Heavy Duty..The first pic shows a 25h.
TF-8MM which looks exactly like the oval shapes of the chainlinks on a timing chain.
#410 which looks exactly like a bicycle chain just slightly wider...…
#410 chain is also used for chaindrive garage door openers..
Theres a parafin wax and oil treatment you can do with some heat inside a metal can that's done to new chains to properly pre-lube to protect the chain from initial damage to the link rollers when initially used.
Im sure theres like 1000 vids on utube on the process that can be researched...Its actually very easy..
Another point to touch upon is whether to use or not to use a masterlink….
I say buy a chainbreaker tool that can do both types of chain and mend both chains without a masterlink…...Theres nothing like losing the link and having to carry or push something so small home.....
