103" Question? : V-Twin Forum: Harley Davidson Forums

Michael M · 07-04-2009, 01:00 AM

I just bought a bike with a 103" engine and six speed tranny. Its a 2007 FLHT P with ABS.

Is the 103 an 88 or 96 with a big bore kit? Is there anything to watch out for as far as mechanical "issues"?

The 2007 flhtp is a 96 cube with a 103 piston kit fitted.

To clarify : the 96 is an 88 Stroker.
The big bore kit that turns an 88 into a 95" turns the 96 into a 103"

I've done both the 88 to 95 and 96 to 103 conversions.

You can go up to a 107 " with your current motor ( Axtell and others sell kits)

Hogbag, I am sorry, but you are wrong. if it is a police bike, the reason for the P, it is a FLHTPI, which means an police bike (all of them had fuel injection) All stroker police bikes(those 07 up) are 103"

Still just a 96" with the BB kit, no? (Installed as it was built)

Try and keep the revs above 2700 rpm in 5 and 6 gear meaning don't drop into 6 until your around 70 mph. Has your bike got a stage 1 kit fitted or is it a stock.

HogBag - I have an '07 FLHP with same engine/tranny setup (stock pipes, no stage 1 intake). Why the caution about not hitting 6th until 70 mph?

My 08 seems to run fine at 60 in 6th, I think I know what lugging is. Maybe I don't understand strokers? Could anyone elaborate?-Al

The 08's have the IDS pulley , I put one on my 07 and it does smooth out the lower revs.
I've had no issues running in lower rev ranges , but I wouldn't go under much under 2500.
