I have a black plate on my '91 Harley and the pipes are Screamin' Eagle II's. Plod hear me coming from a few hundred yards away.
They look up, see it's not a Plastic Fantastic ridden by a Power Ranger (Oh dear..wait 'til Chrisgixer read this
) and carry on what they were doing.
Not been pulled in the 3 years I've had it
Oh dear Turk, fancy giving you age away so easily, we all no in the UK you have to be over 65 to ride a Harley 
Certainly round are way they seam to be ridded by the 'mid life crisis' brigade.

Sorry, only joking 
I suppose there's not much danger of being nicked for speeding on a Harley.

Always had the Plastic Fantastics but got tired of getting home on a Sunday evening and looking back at any "close calls" that day and thinking time to wise up.

Having said that, with the 1200cc conversion, N4 cams and the SE race ignition module, the old Hardly-Movinson hits 60mph in under 4 seconds and pulls solidly to 130mph at wich point I decided to call it a day...legs stuck out in front and hanging onto the bars as if my life depends on it (hmm...which it does actually

) is not an ideal land speed record position.
Have to admit, when I took it for the 1st test ride I did think, "What the heck am I doing on this noisy vibrating piece of sh*t ?" but there's just something about them, within 10 mins I was converted.
Anyone need any ploughing done ?
