Weird question but how long will a Blaster's engine brake?

So you are coming down hill off a mountain or slope and you let the engine do the braking because you do not know any better. Obviously, since you are mixing 2 stroke 32:1 btw, the engine is now not getting any lubrication because you are off the throttle.

How far will it go before it seizes up? Saying this slope is, hypothetically endless.

Thanks @Larry's Shee . When I ride I am aware of the above so coming down hill the throttle will be blipped every 2 or 3 seconds. I never freewheel will clutch in for long.

Reason for my question is, if my kids and their friends use the Blasters, they obviously do not know any better. SO I just want to have an understanding how strong the engine will be in such a case. If that makes sense.

It's not a long hill as such, it's actually dunes. I believe of which the highest would be around 60-70ft and declining around 15 degrees. So it's up and down etc.

Modifications range from full FMF on one bike to stock to oversized piston on the other. All aimed to be tuned slightly rich.

I do run a high quality 2stroke mix I believe. Castrol Racing 2stroke.

Current ratio is 32:1 but I agree with you and will start taking it up to 28:1 when I plan my next plug chops on the bikes.

Regarding the over rev, that is also a concern for me. Thought of adding a block inside the throttle to limit it to 3/4 throttle max. The adjusting screw is just to easy to override. That should surely help a little. How much? I don't know. LOL.

Thanks @Larry's Shee and @Blaaster .
