Harley-Davidson Dyna Fat Bob Questions & Answers

Is there an easy way to find out if a previous owner installed a bigger cam? I big from a dealer and is got Vance and Hines pipes and a Roland Sands air cleaner but I think they may have redone the cam. In going to be buying a tuner and thinking of a stage 3 or stage 4 but don't want to pay for new cams if it's been done already.

gday martin, i spent a life time on sports bikes got old and went over to the dark side and got a 2015 fat bob with low k's. i have to say its pretty good. i thought it would be hard to change over but it wasnt. i did try to put my feet straight down when i was driving away from the previous owners house and there was no pegs there haha. never had a more comfortable seat. i dont really think its for performance although you can do anything to them but if i wanted to go faster i think i would go for a cbr1000rr. i really liked low capacity sports bikes because you seem to be pushing it hard to get the performance out of it. one of my first bikes was a cbr250rr mc22 and i loved it 20k revs on the way to the shops, it sounded like a formula 1 car. i just cruise around now when i get the craps with the world. the biggest hurdle i found was no fairing you get the wind right in the chest, im looking into getting one for my next upgrade. its a big bike so lane splitting is a bit more of a pain than on the sports bikes and i think it is around 300kg but it just chugs along nicely on the highway. and lastly ive never had so many people come and talk to me about it when im out and about, i look as rough as a cats tongue but it doesnt stop them. anyway i hope this helps

Not sure but if you have a 2016, it should be a 103ci! I have 2016 fatbob as well and it’s a stick motor with a 103 ci high output.

Check the coil

I have an ‘09. Pack rat got under instrument cluster. Made a nest and chewed all the wires. All were bare! Don’t know why it still ran! FYI!

Mine comes on intermittently. I have a disconnected oil pressure switch wire at the front of the motor. I've bought a replacement but haven't put it on yet. Hopefully that's what is causing the red light. Apart from that everything else, as far as I know, is all hooked up. I've had this since I got the bike in March 2018.

I ride with a few fatbobs and every bick has had that problem we found it to be the front brake lever is too sensitive and puts the brake light on get it looked at or replaced

the red light means there is something wrong with the bike hold your trip button down and turn on the ignition it will go into diagnostic mode scroll thru till you get a y and it will give you error code google the error code and it will tell you what to replace

Harley Davidson and some other Motorcycle manufactures have a weird system of launching new models which can be confusing, for example most 2018 model Harleys are released new even though it is still 2017 so if you were to buy a new one now it would be sold as a 2018 variant but complied and stamped 2017. I know it is strange but that is the way they do it.

In relation to it being 103 that should be in your owners manual and if still in doubt pop into a Harley dealer and confirm it. The previous owner may have done a stage 1 or stage 2 or higher upgrades with different pipes if that is so then it would have a higher rating.

Harley's new bikes come out around new financial year, so my bikes 2016 but I brought it in November 2015 and it should say on bottom right hand side of engine 103

Take it into Harley dealership its more than the battery et al. Had same problem and was fixed under warranty.

I love my bike. It only shakes - vibrates at idle which is badass. One you turn the throttle even sitting still the bike smooths out. The only other bike I would buy over this would be the Harley Dyna Low Rider S. external link  its a beast with the 110 motor. Mine has the 103, with intake exhaust and dyno tune. Its very powerful. The Low Rider S has a 110 and a nice intake already. Any stop Harley will need a better exhaust. Factory is just too quite. The Triumph's are very nice also. I chose the Harley due to its powerful Vtwin and the Fatbob because its unique.

The fat Bob doesn't vibrate to much for me , I've got Vance and Hines long shot exhaust, stage 3 super tune, screaming eagle air intake but you just can't beat the sound of v-twin engine it's a beast

thank you for your feedback, its been very helpful.

Sorry I do not know.

I've just put a Heavy Breather Corsair version on mine and it goes straight on.

Do you have a photo?

I weigh 80kg so does the wife. = 160 kegs. bike hardly notices the extra weight. Motor has good torque

Don't know Michael ring your Harley Dealer l'm sure they can tell you cheers !!!!
