I'm working on ungoverning my HS 142f and since I haven't seen any "how-to" post which I'll find useful, here is mine, for now "work in progress". I'll keep updating this first post as I can invest hours on this.
Special tools needed:
- Balancer Puller (to pull the flywheel, learned kind of the hard way...) (Looks like you can borrow it from AutoZone) (https://www.amazon.com/gp/product/B01LZLUJJP/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1)
Pieces needed (thanks to Jakeguy24 on this post https://motoredbikes.com/threads/huasheng-142f-to-144f-upgrade-questions.53246/page-2 ):
- Honda or old HuaSheng FlyWheel (Honda part number is flywheel is 31110-ZM7-004) (got from ebay ~$20)
- Honda or old HuaSheng CDI (Honda part number for the Honda CDI is 30500-ZM7-014) (got from ebay ~$10)
Steps:
- Remove plastic cover
- Remove CDI
Comparative between CDis, top one is the new one
- Remove the nut and the metal part of the rope puller
- Checking the differences, as expected, some degrees difference on the shaft hole between flywheels:
- Trying to pull the Flywheel with a "home made" puller (Spoiler alert: went wrong)
End of part 1, I'm now waiting for the puller to be delivered and then I'll keep updating.
EDIT 1 (May 1): I was able to pull out the Flywheel with the puller:
EDIT 2 (May 3):
- Motor is assembled back:
*** Gap between flywheel and CDI it's a little bit to big, the closer the better, even that it worked just fine like this, I ended up moving the CDI closer to the magnet
When I pull the rope, the rpms go up on the tach meter, so ready for a real world test outside, probably tomorrow.
UPDATE 3 (May 5):
I tested it yesterday and it worked, I had to re-adjust the mix screw, but after few tries it was up and running and it reaches 9k rpm with no load (back wheel on the air).
Feel free to add comments to improve this How-To and I'll take care of adding them to the right step here on the first post.
Thanks to all the great people in this forum that helped me accomplishing this and special thanks to CrazyDan
