Top speed question on ‘99 FLHTCU-I

[Firea100]

Good Morning to all on the site!

I have a ‘99 FLHTCU-I with a Hannigan trike. This is my first Harley. I’ve always had Honda Gold Wings and Valkyries.

My question is: My MPH top end is 70MPH. Wide open that’s all I’ve got! I’ve looked and saw that the throttle blade is open as far as it can be with the throttle wide open. The bike has 31K miles on it. It was previously owned by two elderly gentle men (one after another) so it’s not been abused. I believe the motor is the 88 cu.in version. The trike kit adds about 300lbs. to the whole rig. I’m 200-ish lbs. Am I expecting more out of what I have? I’m not trying to set a land speed record or anything but would like to at least keep up with traffic! Any info about this will be appreciated.

Thanks,

Larry in East China Mi.

Is it completely stock?

Yes to my knowledge, it is stock.

Look at your options for stage one ? Consider a cam? Be Safe BK

I guess then, my trike must be “ok” and I have to “update” it for more power?

What RPM are you turning @ that speed?

Gearing ( pulleys) and tranny gears plus a different cam could be a plus

If this is a stock 88 Twin Cam you will want to be looking @ the cam chain shoes soon

Sounds like it . But part of the fun is making it your own! Be Safe BK
