High speed noise

[SIZE=3][COLOR=#000000][FONT=Times New Roman] I recently “triked”my 2000 SE with a Motor Trike and absolutely love the conversion. I have noted one problem that occurs at approx. 60 mph. At first I suspected rear tire noise and thought maybe it was a normal thing on trikes. Last night I discovered that if I pull in the clutch the noise stops and starts again when I release the clutch. Any idea what it maybe? Its 140 miles to the dealer who installed it so may have to bring it back for them to look at. Thanks for any input. I might add I really enjoy this site for all the inputs and vast knowledge on “Trike Riding”. [/FONT][/COLOR][/SIZE]

Possibly a U-Joint / how many miles on the Kit? Lubing that U-Joint at correct intervals..? If it free wheels with no noise, that's generally the cause with the drive shaft pulling!

The kit was installed approximately 350 miles ago. I do not know much about trikes yet but the u-joint also came in mind. Thanks for reply.
