Tomos made strange noise, pedals seized, now running fine?

Fine-ish should I say.

2018 Tomos Sprint

Driving down the block, engine was warmed, make it about .5 mile from the house and I hear this crash/bang noise coming from my bike. Pulled over. Pedals were kinda seized up. Engine ran but bogged down after a second (unsure if related as I was also farting with new carb all week and it was much colder on Saturday). Bike didn’t wanna move. Finally got it to roll, pedals eventually regained some function. Fired up engine, made a very high pitched almost screaming noise, which has settled to just a hum/whine of sorts.

My gut tells me transmission but I’m also a noob. Any suggestions? I will try and upload video this afternoon.

Sounds almost like you soft seized, did the pedals spin forward but not backward?

My gut tells me to pop that cover off and clean out.

I’ve had a beer or six since but I can almost confidently say that was the case. Also “soft seize” would be an accurate way to describe what happened however I’m not familiar with the term. What exactly is that

In my opinion and I’m a tuner of two cycle engines for more years than you’ve been alive in your parents basement (You being A liberal and all Just kidding ha ha)

I had to take 250-750cc Kawasaki triples, Suzuki doubles, triples and others from one shop to another untuned hoping they wouldn’t seize!

A soft seize means you can still keep going but there’s Piston, ring cylinder and damage!

No matter how you wanna be a denier unless you pull the top end and inspect everything! cylinder, piston, expect especially the underside Piston and rings, checking Ring gap, without checking everything is a waste of time!

Case crank support bearing went south. You clutch nut might have backed off.

Soft seizes usually don't scream then go away but a bearing will.

Everything I’m reading about soft seizes on here say the exact opposite?

A bad bearing stays bad until it’s replaced right? I’ve never known of a bearing to be quiet after it starts to go.

My bet is the sprag clip broke. If you are riding and lift your feet from the pedals do they spin around on their own?

It loses a ball click clack it stops screaming or it rotates in the recess.

The seize would have a compression loss at least open her up report back.

i'd pull the cover for a peek. probably nothing, but mine did that and i grenaded a clutch shoe. it still ran more or less normal!!! i would have broken a bunch more shit had i not.
