any1 here have a Semi auto/Automatic 1speed engine ? kids ATV ,pitbike

hi !

Looking for INFO, hopefully this forums Section isnt dead:

06.12-2017
EDIT: ive come to conclusion that Semi automatic might have maybe just maybe diff measures, Hence priority is on Automatic 1-speed version engine....




as per Title, has anybody here got a Semi auto/Automatic 1-speed or 3-speed engine ? china made so called "honda monkey type" engine's..


from either in a kids ATV or at a some kids pitbikes....49cc 73cc 90cc category commonly. also on some 107cc and 125cc engine's that are same Automatic 1-speed.

even a spares joblot dismantled engine will DO as a source of info im looking for.... if lucky, some1 has spare clutch cover casing already separately and parts at it in place, so it would be very easy...

for example, 1-speed Automatic engines are usually on Youth/kids ATV's, like for example on Kazuma meerkat-50cc, etc brands and its Clones, not juts kazuma alone !


im looking for a measurement info for Clutch "pushrod" and adjuster parts, so that i could re-produce them locally by lathe.

like so engine of this type, if identifying only externally.. you can see the Clutch M8 nut and Adjuster rod externally:

Measurement info for this "adjuster rod" part that is with M8 size nut on the Clutch cover casing, as above:

i cant get them parts ordered as OEM, not available in my country. and my freeby salvaged project engine is missing them parts. Not either Economical to order overseas import as new parts.



i only have sample photos of them parts but no Measures.

in total im missing 2 vital parts of the adjuster assembly. i have sample videos from youtube and some more photos from web. so i have info to show.


it would be fantastic if someone would have these parts and able to help.

im willing to pay little fee for help, if its needed.



ive now spend 1,5years waiting for a engine to turn up on Bike Breaker yard 300km away from my home, to take Measurment data from, but no luck yet, not a single engine or remains...
so im getting desperate. i live in a arctic cirle backforests about no where, very little population and machines around, no help.


any China made (as titled) engine is ok for this info as a source. no matter what manufac/brand. they all should be accurate clones...


i have 1-month left before Xmas closed-up/holiday, to Produce them parts at my ex-machinist school. after that its Jan 2018-> next opportunity to get onto waiting list...


please, send me a private message if you can help, so that i get e-mail notification. i dont use this forum regulary ! so any reply posts on this topic might get missed out...


i hobby various Chinese made mopeds scooters atv's etc small engine's. i have many projects, and This piticular 1speed automatic motor is in Desperate need of a Help, as per Titled.

List of missing parts, that need accurate Measures-basic handsketch drawings, and some photos wanted too.


1. adjuster bolt

2. some sort of "bushing insert" is missing , that is located between "pressure plate" and ^^ above shown Adjuster bolt.

pressure plate is the part#3 in this photo:

the missing "bushing insert" most likely is Threaded inside as it works in Combination with the "adjuster screw".

- "bushing insert" shows at this video^^, from 1min35s , right after Clutch cover casing is taken of.
- from 1min39s shows the "adjuster screw" from inner side, when its in place at clutch cover casing. obviously look like it doesnt have any "extra" parts fastened into it. this should be double checked.
- at 2min14s person at video removes the "pressure plate" , and the "bushing insert" is still in it at the Middle in place.


3. missing part is the "external M8 locking NUT" ,but that should be afaik Metric standard M8 nut. not a problem.



at my Clutch cover casing. i have the oil seal in place, for the Adjuster screw, nothing else in place.

as previously mentioned, all these automatic engines should be identical, but a Simple measure check would confirm basics...
-Depth from gasket surface at Clutch Cover casing, to Adjuter screw hole flat surface Would Verify that clutch Adjuster parts do not varie by measures, and are cross fit able...



i used to be a Metal worker, TIG welder etc Sheet metal fabricator. i have a degree from Machinist school, where is studyed 3-years nc and cnc lathe's mill's etc. old school Fanuc nc. regulary i used also manual Lathe's when at school. at school i spend my freetime Making motorcycle parts, which i have Continued until this day, School ended at year 2000.


so, hopefully a help given is accurate. NO NO for loose verniers or rollmeasures, FAIL.

handdrawn basic sketches dont take more than 5-mins, taking a photo 15-seconds.
writing into this topic X amount....


but if needed, i can draw them hand sketches and e-mail to Helper. anyway them are not much different from 5yo child drawings, so no big deal should not be a issue for any1 to draw.


Also Tips welcome if some1 knows usable sample photos at web for them missing parts, as a Comparison visual material, for double check purposes.

i have spend mahosive hours looking from web with not much results, but hey some1 might know "new to me" finds....

up !

does any1 have any help available ?

as a souce of info is needed: Automatic 1-speed engine from Youth/kids ATV's 49cc 73cc 90cc. on some occasions 107cc or even 125cc.
