How much will a motorcycle tire swell at 300mph | Will it EXPLODE?!?!? | Lark Machine Co

- I need to do some more testing on the beast and now is the time to spin up the back wheel and see how much the back tire will grow.
Kinda scary!!!
Put a motorcycle strap on the swing arm to over the frame to mimic your preload so you can watch your chain rub. I run one with a rachet strap over my frames and hook them onto the rear of the swingarms. I do this when I adjust my chains! Then set the bike on the ground with your weight in the cockpit to mimic almost full load. ( If you want to really be accurate, now that the bike has done a few runs, add some ballast to represent the bodywork, batteries and everything to race day weight. )
It looks to me that the chain is making contact with the frame on the inside. (Could be dry chain sparks!) And by preloading the suspension to stock ride height it will make it easier to determine how far back you need to set your rear tire.
I realize I'm late to the party, but didn't see anyone reccomend this to you. Hope you've thought of that idea before now.
Thanks for all the comments and views!!!! Chain tension under bike load is good and the chain has much less slack. I'll take a video next time I run. I definitely need more lube. Every run I sling almost all the grease out!!!!
Keep it up boss it’s been awesome to watch progress and love the diy angle of everything!
You da man. I was reading you comment expecting to rhyme!!!!
Excellent stuff
Cool test. Wouldn’t there be even less clearance on the top when the full weight of the bike is pressing down on the bottom?
There is something they call a standing wave that move through the tire. I guess the deflection on the tire on the ground deforms and pushes rubber out past the ground. I have no clue how that will effect the swell, but at least we are beyond what others have run successfully
One good thing, will the tyre swell help with your top speed ?, sort of like removing a tooth to your rear sprocket , but as you ride along, looking great Shea. Couple of chain guides or rollers wouldn't go a stray, that was a wicked video of the chain !
Finally something works in my favor
Keep up the dream!!!
Thanks for the support!! It's getting close to being a reality!
This is got to get you some Views
Out of curiosity why does nobody make the wheels the electric motor?
Mostly for bicycles there are some for motorcycles. It would be ideal for landspeed, but lots of unsprung weight would make a motorcycle non ideal
Build the modular Thorium Reactor as a fluid fueled salt breeder that starts with old nuclear bomb 235.

Nice, Easter egg find!!!
Seeing the tire expand at speed is wild! Also super crazy what is going on with the chain. When you do a speed run with you on the bike will you use a riveted master link on the chain?
I wasn't planing on it running rivoted masterlinks. That might be a better idea though. The chain is doing some crazy stuff!!!!
@@sheanyquist Yeah the chain almost looks like it's flowing like water. It would be interesting to measure the temperature the chain gets up to. I wonder at speed like your tire the chain gets LONGER as it heats up to that speed. That is what makes high speed vehicles and planes so interesting. I am sure with high speed bikes there are all these little things that are not in a book you can reference. You are doing cool stuff!
I am hoping we are just one big jump in battery density so it's fairly easy to convert old motorbikes to electric. I want to see people riding crazy electric conversion 60hp+ Ninja 250's.
@@wootks it funny you mention the temp. It was hot to the touch after just one test. That might be an issue
Won't even expand even more when hot at 300mph?
Heat will increase the pressure. It shouldn't have to much effect on expansion
