My TBS went boom.

Smoked up at a stop light developed a very sudden and intense rod knock and oil is glittery.
Huge bummer but I guess I can look at this positively, new engine time. I want one of the higher horsepower triples that fit in the frame. Suggestions? My 98 TBS had green cams and with the right jetting had around 100 whp. (I have Dyno sheets to prove it 😉 ) so I definitely need the higher power. I'm gonna keep this engine as a spare for things that may be useable but I'm fairly certain the bottom end is toast as well as possibly my green cams. I have an ignitech so no problem remapping for a higher power bike. Or if anyone is selling their speed triple, Daytona, or trophy motor I'll gladly bite. Just let me know.

Bummer... Why do you think it failed? Was it high mileage?

Rod bearings are generally the first thing to go when there's an oil pressure problem. If that's the cause, the cams are probably OK.

That sucks, but sounds like you have a plan to getting it back on the road. Good luck with the rebuild.

I don't know if the cams will be ok. If the issue was oil starvation, the top of the engine will be the first area to run dry of oil You'll want to inspect and measure the cams very carefully. If the cause of the rod bearing failure was something else besides oil starvation, then the cams may be ok.

What a shame! Beautiful bike to look at for sure. You are a talented man. I hope you do a heart transplant and keep the rest the way it is. Keep us posted on the surgery.

15k....!!!! That isn't a lot of mileage for that to go pop. And like you say, taken care of too. Triumph really need to look at reliability, that is far from acceptable, nice looking bike though.
