Tim Seymour that's the most fun part, dreaming and picking parts out. You need to go to ebayUK to find them. Usually 3 or 4 on there at a time. You can find all the rc42 parts there. The rc42 oil cooler is a direct bolt up and gives you twice the cooling ability.

Thank you very much. I really loved this bike it was a joy to ride.

Don't know about OP, but with these mods 120 mains would be appropriate. carbjetkits has a calc for the cb750 that u might find handy.

TS7 getting that tank is certainly not a cheap thing. You're going to have to order one from Europe or Japan. They never made it in the states. You will have to do a little custom work to get your side panels to snap in but it's just a little bit of grinding with a Dremel tool. The tail unit for the RC 42 I believe mounts right up to the existing mounting points. I really thought about doing the rc42 side panel and tail but the cost just got too high. The side panel tail tail lights and seat would have ended up pushing me over my budget.

You also have to mount the rc42 tank in order to safely Mount the better-looking low-rise Superbike bars I have fitted. The stock Nighthawk teardrop tank requires high rise bars.

The RC42 tank bolts right up, but you need to trim about a 1/4" inch off the fronts of the side fairings to make them match correctly. Unfortunately as the RC42 has a disc in the rear and dual disc's up front. You would need the rear swingarm and front forks from the RC42 to do the wheel conversion.

Jay Ruiz the front signal/side road lights are two whay yellow signal and white driving light. The flexible signal is mounted to a custom cut aluminum frame that wraps around the top of the fork arms. That custom aluminum frame is bolted through the top triple clamp bolts as you can see in the video at 3:18. Not sure about the switches just get on eBay and look up 7/8 in LED toggle switch. The light below the headlight is a high-power off road spotlight that I custom modified to mount to the bottom of the headlight I installed. The headlight comes from kapscomoto.com. The standard low-power bulbs are replace with high power LED units.

yangheon Lee that was the biggest installation nightmare of my custom motorcycle building career. It is a huge ordeal to try to fix the sensor so that it will read RPMs. You will need to get a combination of capacitors and resistors. There are several forums that discuss how to do it. You just have to create a small circuit with a resistor and a capacitor in order to alter the frequency of the signal being sent from the engine itself. Don't try going from one of the spark plugs it will not work as the Nighthawk uses a special spark system that does not translate to any other type of tachometer. It's one of the reasons night tachometers are insanely expensive online period is because nothing else works for them. Like I said sit down for a couple of hours and use Google to search "Installing cheap eBay tachometer". Tons of people have face the same issues we have. And there are a couple smart electronic guys who figured out how to alter the frequency by putting small circuit in between the signal line in the new tachometer. After a year of trying to install the tachometer speedometer correctly I finally got it to read between 2000 and 8000 RPM correctly and the speedometer was absolutely dead on with GPS speed. Once you actually get the tack sending a RPM signal you will have to start to decipher how to actually set the tachometer. Setting the tachometer correctly allows it to read the RPMs correctly and the speed correctly from the magnetic sensor. That will take you a few days of playing with as well. I would just have your phone on top of your gas tank with a GPS speed showing write it for a little ways see how close the speed is and then pull over and adjust and keep doing this till the miles per hour match what your phone says. Good luck, and feel free to ask me any other questions you have.

Can you describe where did you connected the circuit to read RPM signal? To the coil? What values of capacitors and resistors did you use? I assume that you build a filter... can you send me a link to page with diagram? I tried to connect filter circuit to ignition coil but with no luck.

They are low rise "superbike" style bars.

Yea I agree, whats the digital speedometer and tachometer?

Jaime Althoff not sure of part numbers but if you just search electronic speedometer / tachometer on eBay you will find this one quickly. I do warn you it is an absolute nightmare to install and took me over 8 months to finalize. Going back I would have made a different decision. It looks super cool and has all the functions that I want but it still was not worth the pain in the ass I went through. I'm running low rise Superbike bars. The gas tank is a Japanese / European Honda RC 42 gas tank which you have to have in order to run the low bars on a Nighthawk. The RC 42 gas tank bolts right up to the Nighthawk frame because both bikes shared the exact same frame internally. The headlight is a slant front Cafe Racer Style from Tapsco Moto. You have to do serious modification in order to mount the non side-mounted headlight. The horn also has to be relocated to the right side of the engine as you see in my video. This is so you can mount the headlight low enough to make it look right.

Mark, so the tank lines up with the side covers? Any modifications needed to use that tank. P.s. It looks great. Thank you for sharing your work.

@@bobs2440 you have to do a little dremel work on the top of the side cover. Not bad though.

Totally different bikes. The last gen Nighthawks were good bikes with one hell of an engine. Always enjoyed riding mine, and it kept up with much more aggressive sport bikes.
