Hi all, Im a new member but a long time reader.
New Predator 212cc. OHV. 6.5hp.
Some breather mods, rejet, lightweight flywheel, stiffer springs and governor removed puts it at about 9-10hp and up to 5000 rpms.
Future mods would be shave head for higher compression ratio and more aggressive cam. So maybe 12-14hp and up to 7000 rpms.
Its installed with a torque converter on a tractor style gokart i made. It gets ripped around on the culdesac with the kids and used as a pit vehicle when i go to the race track. Looks like it will get 20-30 hours of run a year.
Temp used in will be 40-100°F. Planning on ripping it around in winter too but my garage is heated so oil will be no less than 40°F.
0-3 hours was Supertech 10w30 (blue bottle)
3-12 hours is same.
2 things that worry me. Sump holds just 0.5 quarts and being a flat tappet cam with stiffer springs.
Factory recommends 10w30 but thats for ungoverned motor that barely sees 3500 rpms.
I know i need high zddp and possibly a synthetic.
What oil should i use to change once a year with my use?
