Yo Gang,

Just went over 65K on the 99 Speed Triple. Put a Power Commander in her a couple months ago and she is running like when I got her new in Nov. 98. Great bike.

IIMike,
I've got 60K miles on my 97 T595. I have replaced the 'soft' valves with 'black nitride' coated ones and had the head milled at 42K. She runs great with more torque and no flat spot. Now I hardly ever have to run her up near redline to get what I need. Do you have any oil consumption. I have just a little. No smoking, just uses a little after 3k miles, but then it's time for a change.

3forme,

Haven't noticed any extra oil usage on mine. I will keep an eye out on the little window.

Speed3,
The shop here in Portland got them for me when they did the work, so I don't know the source without calling them. They were a step above regular stainless valves. The nitride is just a coating like they put the coatings on fork legs to make them more slippery, the 'black nitride' is a 'hard' coating.

You'll know if you will need them soon, as your clearances on your valves will beging to get tight and not last very long before they get tight again. That's the valves cupping. I took a look at mine after they pulled them out. Triumph just got a few batches of valves from their outside supplier made out of soft material. Another way to know is that if you haven't checked your valves in quite some time and your bike gets harder and harder to start, that's your valves not closing all the way (too tight of tolerances). A quick compression test will confirm it.

That sounds exactly like what my '00 Sprint RS was doing. It was getting hard to start again within 6 or 7 thousand miles of the 25K valve service. But before I was forced to do something about it, I totalled the bike during a trip in Arkansas, and ended up buying my Speed Triple with the insurance settlement. Your method of fixing the problem is much better.
:knkknk: :wink:
