I can't stress enough how much you want this racing kart split ring adapter plate for your Doodle bug mini bike.https://www.ombwarehouse.com/Doodlebu... You can see I almost got the tallest gearing ever, 35 tooth on the rear. You don't want to go that tall less you got a jack shaft to even change the gears more. Best thing, my stock doodle bug sprocket was as big as the tire, and would hit any #3 or larger rock kicked up cornering on that side. This is the 54 tooth split ring sprocket and plenty to small. Warning; if you using the stock 97cc engine, you have to with more teeth on the sprockets, If your using the the Harbor Freight 213cc you can start with 5 teeth lower, 65 tooth. Get these $11 sprockets from OMB to start to. Till you fine the perfect gearing you want. Remember, you can always cut the #35 chain down, but to lengthen it is kind of stupid of you bought the small gear like I did. But I got a jacksaft, and jacksaft gears are only $6 to $15 for the biggest, you have to check on that, I'm close though. Don't let all my comments bother you, I'm just bullshitting up the weak minded trolls that don't know the difference yet and come here to start shit sooner or later, mostly cause they're jealous as anybody would be, you got one first from watching Mr. Midshipmans channel. Sides we talk to our friends, not our neighbors the same way and they talk the same bullshit to.
But let me give the trolls credit where deserved, they ruined my channel. Constantly trolling and badmouthing me to, make me angry. So I hope I'm acting angry enough now. I laugh at em for trying to anger me. That's what some channels told me.
