Default 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..
