Massive exhaust failure
Ok so today I was leaving work and decided to have some fun with a 750 suzuki. I was playing with him as we got on the highway I let him gain a few car lengths while pacing before dropping gear and actually getting on it to play cat and mouse with him.
Hit the accelerator hard and heard a pop and the bike got A LOT louder. Instantly shut the bike down. When I redid the exhaust the one thing I didn't change was the #6 sleeves (part number 18392-MG7-750 I believe) because they were still fairly new from the previous owner. After pulling the exhaust/ header back apart I found that the one coming off the rear cylinder failed and injested it's self into my pipe. Temp fix until the new sleeves come in was aluminum tape with a small bead of gasket maker. The leak is now temp sealed up. Point of the story: I looked like a fool as a 750 stroked me over a cheap part and this is my "noob mistake" of the week. Hahaha |
What kind of Suzuki 750?
Any GSX-R 750 since about 1996 will absolutely smoke a Superhawk. |
Not true. I lead my friend through an 1/8th mile. He is on a 2004 gsxr750 with Micron and PC. My gearing is supershort though :)
I also trounced a well modded cbr600rr in about a 1/4 mile. Left him for dead at the top end of 2nd. These superhawks sure are fun... :) |

You talkin' about the lead type gaskets for the stock exhaust? If so, I have a couple that I dont need anymore.

Yes it was a gsx-r but the rider is new to motorcycles. So new in fact that he uses the clutch to shift instead of sweet spotting it.
Crux are they lead? What I pulled off looked to be graphite based mesh. |
Shifting without the clutch will blow out your exhaust gaskets due to excessive loading of the endline rotary girder.

You have been warned about the endline rotary girder. And it's easy to keep up with a rider that's scared to open his throttle during 5 o'clock traffic no matter what bike he is on. |

PM'D you. Thanks once again.

I had to replace mine a few weeks ago (when the previous owners method of using a gasket sealant in place of the required piece failed after almost 2+ years having the bike myself)
Luckily being in Los Angeles, there were multiple dealers that had it in stock locally so I was able to get some that day |

I have heard these bikes have "carb farts" , but what is this ? |

Wasn't a carb fart. Literally the pipe popped off the rear jugs header pipe where it ties back into the main pipe to the exhausts. The seal there shelled itself out and allowed it to drop. After that I shut the bike down.

Clamp could not have been secure or the gasket was extremely damaged to begin with. This gasket is captive in the pipe under pressure from the clamp.
