Refer to post " when to walk away from bike".

 

There are several ways of getting a 'bigger' motor:

• modify your current one,
• find a bigger genuine Harley motor, which can be had secondhand,
• buy a Harley exchange 'long-block' of larger capacity, up to 120",
• buy a brand new aftermarket one, such as S&S - 111", 124", or how about a 143"?! That should fix any craving pdq.

There are HDF sponsors such as Fuel Moto and Hillside Cycles who can supply a range of upgrades, so it is well worth contacting either or both. Depending what size you go for there may be other essential upgrades, such as to the clutch and exhaust, new fuel injector, etc.

 

I'm guessing you are talking about replace the motor and transmission here. Put an S&S 111, and a Baker six-speed and call it a day.

 

That's a lot of $$ to put into a 15 YO bike. I would trade up for newer; prolly cost the same or less.

 

Um.....yeah.
If your for real.... Which I doubt. Sell that bike. Buy one that already comes STOCK with the features you desire. Just sayin'.
