Dumb question maybe, but I want to upgrade the engine on my RK. How much should it cost me to turn the 103 to a 110?

 

There's no such thing as dumb questions. Only dumb answers.

I suppose the cost would mostly depend on where and who does the work.

By the way, very nice looking Rocker C. Wish I could aford one to cruise around town on.

 

I dont have any independents around. Dealer would do the work.

 

MSRP for the kit is around $1,500 according to this page. Then you get to add on the other stuff you need but don't get in the kit, and an ECM recalibration. Prolly be well past two grand with labor figured in.

That's a lot to pay for 100 ccs, but you do get the coveted and much sought-after "Screamin' Eagle 110'' medallions on those new jugs.

 

Thanks.

 

I'm not sure on a stock 103" but I know on my last build (stock 96") the biggest top end I could go with was 107" - without getting into the bottem end, splitting/boring the cases etc... I memory serves me right it gets into quite a bit more money at this point so that's where I stopped!

Good luck!

 

The engine cases have to be bored to accept those cylinders so the labor starts to get kinda high. A 107" big bore would make more sense. If a guy is gonna take the motor out and bore the cases then the crank needs to be taken care of and I would go a minimum of 113" and probably 117" as it really isn't any more money. A 110" at the dealer as stated will be well in excess of 2k and most likely disappointing. If you do a little looking on here you may find a couple of sponsors that can supply you with the needed parts and the install support to do a 107" that will car kill the 110" dealer set up for a lot less money.

 

 

costs almost as much as a sport bike !

So you could keep your Harley as is and about have the money for a bike built to go fast, stop fast and handle.


'cause once the motor is built ( and reliability and mpg reduced) you next get to deal with beefing up the rest of the drivetrain and swingarm and chassis and brakes and suspension etc.

it's a slippery slope!

I've seen a few Pals slide down that slope, eventually selling their bike and starting over.

107 would be a better choice and as previously stated will out perform dealer installed 110 and no case boring. I have had two 107's both HQs kits -- had to upgrade the clutch, exhaust and get the bike tuned -- mileage is just as good as stock, performance wise the bike is a blast to ride. Once you start building motors you will almost always want more.
