1. What oil are you guys using in the final drive gears? Online manual I have says 4 OZs.80W90. There's a sticker on the engine that says 15W40

The oil I drained looks to be 15W40

2. Where do you fill the gear lube???? I see the drain plug, but there's no other bolt to fill it with.

3. Can the Howhit engine be bored for a 62mm piston? The wall is extremely thin by the timing chain already.

Thanks
