You need to replace the engine mount bolts on the Vader 125 (Grom Clone) plus add a third mount.

Since I was asked to put in the links to the parts, please look below for the parts list and links

(What I use) Grade 12.9 engine mounting bolts : https://amzn.to/3PjCDQL
Grade 8 (class 10.9) mounting bolts: https://amzn.to/48fPjk4 (This should be good enough if you are putting in the third mounting point, they are way stronger than stock but half the price of the 12.9 bolts)
(What I use RED ONLY) Mounting plate/guard for third mounting point: https://amzn.to/44LnLA9
(Other colors but a bit more expensive) Mounting plate for third mounting point: https://amzn.to/3raKGaq
(What I use) Anti-Rust Washers- you wouldn't think you'll need them but they work as perfect spacers for your engine mount. Also come in handy with other Vader mods: https://amzn.to/3Lm6Opd
(What I use) Loctite: https://amzn.to/44Pa0ke
