Not sure if you can get much from the video, but here it is running:

https://youtu.be/xoRAR-xQjCQ">https://youtu.be/xoRAR-xQjCQ" type="application/x-shockwave-flash" wmode="transparent" width="640" height="390">


Last time it was ridden was 11/25/17. I clutched in and it just randomly died on me. I was able to jump start it and that's when the detonation started. I had to ride it about 10 miles home doing WOT in 3rd and 4th gear.

Starts up no problem, timing doesn't sound off. The coil/wires/plugs have all been replaced within the last 2-3 years.

Thanks in advance if you have any ideas.

edit: here's the link since I failed on the imbed - https://youtu.be/xoRAR-xQjCQ

Perhaps something wrong with an exhaust valve?
Messed up seat or maybe hung open a little?

Actually, the more I think about it, If one spark plug wasn't firing, the air and gas would go on into the muffler to be ignited sometimes by the other jug.

I think the first step here is to determine if one header gets hot first when you start it up.

You may just have a bad plug or some other dumb cheap thing.

Thx, Nate. Prob shoulda messed around w/ it before posting. Hope to have time to do so soon.

I've been a bit worried abt my VR, for... reasons and thought that may have something to do with it shutting off.

When I have friends over and fire up my Firebolt, then they rev it at idle and foul my front spark plug, that's exactly what my bike sounds like.

The suggestion to check the temp of your header pipe is spot on. I carry plugs and the tools to change the front one with me wherever I go, you never know when someone is going to blip your throttle when the bike is cold...

Thx to all for the input. The bike is staying in my folks' basement about an hour from me so I still haven't had a chance to look.

It very well may be a fouled plug, at least that's what I hope for. However, that doesn't explain it's behavior the last time I had it on the road.

Once it is running right, I think I'll be too afraid to get more than an hour from home on it. Not a good feeling.
