I have an SP1, it has had a slew of issues that I have been trying to repair over the past year and a half.

Here is the scoop, The bike starts fine, will run until it warms up, then runs rich. Very rich, it spits and smokes then eventually dies. I think it's a temp sensor but I don't know which one would cause this.

There are no silly suggestions! I'm open to any and all help!

Thanks
Geoff

Does your FI light come on?
And if so, have you jumpered your service connector to check which code is indicated?

I should say, that it does begin to come on as the engine dies but does not stay on and when the bike cools down and I restart it, it is not on.

I read about a similar problem and it turned out to be the Fuel pressure regulator.
Any thoughts?

I'm sorry to hear that. You might try to see if the ECM has memory of some problem data stored in it. Check out the service manual page 5-7.

OR

You could always take it to the repair shop.

REPAIR SHOP!....That takes all of the fun out of it!..lol......It's a track only bike and it's a back up at that, so I don't want to put any money into labor. Bikes are easy. With help from some one on here, it'll get fixed. Besides, how many parts can this thing have anyway?lol

With no FI codes detected, then it shouldn't be a sensor issue.
The fuel pressure regulator is a likely culprit.
But it should malfunction at once, not only when the engine reaches operating temp.
But things often don't behave the way one things they should at times.
