Hey Yall
I want to put the HP Oil pump drive gear on my 12S...
What kind of work is involved with replacing the gear, and where is it located on the bike?
thanks |

Its under the cam cover, and to pull that (the right way) you have to remove both rocker boxes to relieve the spring pressure on the cams.
Rumor has it you can do it without pulling the rocker boxes with strategic use of a paint scraper, but experienced folks say that can also ruin a plain bearing on the cams (as they will be under load and only supported from one end).
Is your old gear worn? There is no difference in performance, just in longevity, and not all the bikes consume the gears. You can drop the oil pump and look up and inspect the thing fairly easily. |

Well I live in the south, and its pretty hot here during the summer. It seems like the cooling fan runs constantly when im just crusing around. I figured that putting the better oil drive gear would help keep the engine cooler and take a load off that poor fan
Ill probably take it to the dealer to do it, hopefully it wont cost too much |

The new drive gear and the old drive gear are functionally identical as far as I know, the new one just does not wear out.
Are you running full synthetic? That helped on mine. The fan runs less as it got broken in as well. |

The pump drive gear does not change the oil pressure or flow rates so it in and of itself won't do anything to cool the engine or take any load off the cooling fan any more than the original drive gear does.
I'd suggest either looking into an oil cooler or a higher pressure oil pump, but I'd lean towards the oil cooler.
In the end though I think that cooling fan will still be running just as much. |

I have full synthetic... i run synthetic in everything, even my lawnmower haha
Why do they call it a high performance drive gear if it really doesent help anything??
how long should a gear last?
the xb12 comes with an oil cooler already on it, so is there an aftermarket one that is bigger?? I think that one is pretty dinky |

How long it lasts depends on the motor. If the oil pump mating surface was machined parallel, it will last forever, if it was machined not quite parallel, it won't quite last forever. If it's a mess, the gear can die withing 15k miles. You have to drop the oil pump to tell what category your bike is in.
The Tuber to XB migration seemed to make things much better, but not perfect.
They call it high performance because it came out of the race program. Running the bike at high revs for a long time will make a gear eating bike eat gears really fast. This is the race part that solved the problem.
People have reported good results with adding another aftermarket side air scoop. |

Hello all,
I have a 2002 X1 with the full Buell Race kit. When running correctly the bike really hauls butt. 2nd gear wheelies the works. However, there is a really annoying dead spot/lean spot at around 3000 to 3500 rpm. The bike surges, coughs, and sputters. It acts as if the AFV is leaning down until it reaches a point where the bike won't run any longer, then enriches the mixture back up and it starts all over again. If I blip the throttle it responds normally. I almost think the ECU is resetting, which causes the engine to cut out, like a reboot of a PC. If it weren't for this one annoying thing, the bike would be perfect for me.
I have about 12000 miles on it now, and its always sorta done this in varying degrees. I do have the PDA/Scan tool and have done a number of TPS resets. This helps a little. No errors codes reported either. I live in Denver and on a hot day the density altitude can reach about 9000'.
Second, I've heard that disconnecting the white wire from the ECU will improve mid-range. Any truth to this?
From reading what other people have posted it looks like it might be the side stand switch or a leaking intake seal.
Thanks,
jason |

Yes, I am positive your problem is absolutely and completely unrelated to the oil pump drive gear. |
