Boom 125-11 rattle

Redex00 · 05-06-2020, 08:55 AM

Hey guys. First time poster. My bike rattles pretty bad when you rev it. What do y'all recommend to do about it? I'm going over all the bolts today but I fear the plastics rattle against each other. Thanks for any help.

Place rubber washers behind the plastic where it bolts to the bike. I've done this to on both my bikes and ATV. pretty much eliminated all the rattles.

I bought rubber washers and some felt pads. Don't think it helped when it winds in 1st but I've been reading about chain slack or the chain could be hitting something plastic. Tomorrow should be a nicer day. Oh and I realized I've stripped where a bolt should thread through.

The chain is definitely not the rattle. I think I found it, it's either the battery or the plastic battery holder. I've held both in place with my hand but it doesn't seem to stop it. It's a super loud rattle so I'm determined to get to the bottom of it!

Check the horn. My Hawk horn rattled real loud. I was happy that it stopped working so i could replace it with a better one. My X22R has the same rattle in the horn but not too loud yet. I can see i'll be replacing it sooner or later.

I'll check out the horn next. Never know. My neighbor listened to it and he says it might just be the engine. I've never had a motorcycle before, only a Chinese scooter once but it didn't sound like this does. It's almost unbearable to ride in 1st any higher than 5 or 6000rpms.
