Hey crew,
So I have a newer non-hemi 212 predator. I applied the stage 1 kit form OldMiniBikes and also added a flywheel to the equation. I added most of the parts and noticed that after the fact the pull cord was soooooo tense when trying to pull the engine by the valves. I did some trail and error and removed the valve spring and replaced with stock ones and it went back so a smooth pull. Can anyone shed some light on this if it is extremely hard to pull over the engine once you put on the 18lb valve springs? I thought it wouldn't be too bad as these are basically the lightest performance springs you can get. Maybe the valve lash is too tight? I set them at the stock specs but maybe they tightened up after an hour or two of use. I literally broke 2 pulls trying to start it and i usually need someone to sit on the bike when I pull it over so i don't pull the bike up with the cord...
Any advice or recommendations would be appreciated.
