| | Re: Exhaust leaking black oily gook Norman, if you can make me a gasket that would keep oily gook from leaking, and it fits correctly, I'll buy a couple depending on what price you decide on.
I tried the ford gasket, but it wasn't the right size; I tried cutting it but it I ripped it in the process. |

| | Re: Exhaust leaking black oily gook PM me your address Seattlemike I'll send you a gasket and you can send me $1.00 that should cover the shipping and the price of a gasket envelope etc.. It will be a stock sized gasket if you want to match it to your exhaust use a dremel sanding drum to open it up to match your exhaust/muffler flange. I'm out in the shop now making you a couple of gaskets.

| | Re: Exhaust leaking black oily gook Hi, I just got home with that Ford EGR gasket that Fairacing suggested. It's not as thick as I had hoped for but EGRs can get very hot so we will see. I was just wondering if I should cut out the center a little as it seems a little small. I would rather not as this will make the gasket very skimpy and fragile. What do you think? |

| | Re: Exhaust leaking black oily gook Try it as is, if it seems to detract from performance, cut it open a little. You can laways get another.

| | Re: Exhaust leaking black oily gook Very odd, my post in answer to bikeguyjoe is gone, anyways....Mike is correct, I just finished putting it together and I had to enlarge the two bolt holes on the inner edge but just a very tiny amount. Yes it is made out of metal but I used side snips/side cutters.
I left the centre like you said bikeguy joe because it really is hard to cut.
On the brighter side, I like the fact that it is metal. The perforations will compress into place and this may last for awhile. Also sanded down my rusty muffler and gave it a nice flat black paint job with BBQ paint. |

| | Re: Exhaust leaking black oily gook Went out for a ride and remembered that I had food on the stove. Gasket is great so far but the paint on the muffler stinks a bit. Hope this goes away. So far so good. |

| | Re: Exhaust leaking black oily gook I dont know why you guy's are having so much trouble, it works for me just fine. I've used a chevy gasket and a ford gasket with no problems. I'll post some pic's when I have time and if I can I'll make a video for youtube to show you. |

In my experience the paint will burn off only to the muffler itself (and leave a nice grey patina) and the rest will bake on and quit smelling after a few miles.

| | Re: Exhaust leaking black oily gook On the petrol smell problem..
The issue is probably the length of the exhaust - there is a reason why motorbike pipes exhaust right at the back of the machine - it means the rider doesnt get covered in fumes and other enginey delights..
The only machines I have ever seen that dont have long pipes are the machines from the 1900s which were pure performance bikes such as some of the boardracers.
The problem is easily solvable - a length of heat resistant piping running down and secured under the crank and along one of the frame supports so the fumes exit aft of the driver should solve that..
