2020 Honda CRF110F Refresh

Went with a gold RK chain, in person I thought the gold looked good but in hindsight now looking at these pictures maybe silver would have looked better.

Kickstand was powder coated and I picked up a new OEM spring(It didn't have a spring on when I bought the bike).

Installed the chain guards.

Muffler and heat shields installed.

And now I'm back to waiting on parts, as mentioned before I ordered a OEM wire harness from Japan, it took them 10 days to ship the part, 20 more days to arrive only to find out they sent the wrong part. I shipped it back to Japan, its been over 10 days and they still haven't shipped out the correct part so that will be while yet.

I'm also waiting on handlebars, they were ordered 6 weeks ago and should be here any day, then I can move on to those and the controls, etc.

I can tell you are a fellow canuck from your toolbox.
Great project!
 
Nice job! I'm doing one now too. My original goal was to do a full restoration on it (2023 Honda 450RL) as it has 3,500 miles on it. Now I'm in the middle of a conversion to a 3 wheeler and think I'm going to make it look nice but not go overboard which is typical of me. Yours for a kid is overboard but I certainly appreciate the workmanship and the heirloom. 🫡 braaappp braaaap
 
Small amount of progress made.

The handlebars came in, Renthal "Playbike" bars and got them mounted up.

I had no idea Renthal was a UK company.

First thing I did was swap out the bar pad for a blue one, it was hard to find a blue one that didn't say Yamaha so I went with this Pro Taper one.
image003.webp


On to the controls.
image004.webp


The new handle bars are taller than stock but not as tall as most of the bars people put on these pit bikes as I still wanted it to be comfortable for the kids to ride. However the stock length throttle cables have very little extra room so I had to go to a set of BBR +3" cables which are a bit too long and bind when I put them through all of the cable guides but that's easy enough to just leave them out of a couple.

The stock length brake cable has some extra so I just picked up a OEM cable for that. The original was in rough shape.

Grips are ODI lock on, since I've used lock on grips the first time I've only used them where I can, can't beat the convenience. I had to get a special cam for the throttle tube but that's no big deal. This also gets rid of the mini sized stock grips.

The front brake lever was almost completely seized, after cleaning the rust from the pivot points its smooth as glass now, also gave it a go over with the polishing wheel.

Still have to install the brake cable.

Also STILL don't have the wiring harness, I'll save you guys the details but its been months of back and forth emails, delays, wrong parts getting shipped, etc but it appears the correct harness is on the way from Japan as we speak. On the upside I'll be getting it for free because of all of that but I'll wait until I have it in hand to celebrate!
 
New wiring harness finally arrived!
New on the left, old on the right. The old one doesn't look bad because I cleaned it well but there was a lot of sins hiding under the electrical tape. I considered making a new one, I've done it before on a EFI bike but its at least a hundred hours of time I just didn't want to invest.

After switching over all the sensors and electronics it was pretty simple to put in, also installed the airbox and had to install the rear fender since it has to go in before the battery box.

And now with the fender on you can see the color reveal lol.
Yes its Yamaha blue, the kiddo really wanted it to be blue like her old bike but I had originally told her tough luck, I wasn't going to spend the money just to change the color. Then one day I randomly came across this set of brand name (Acerbis) plastics for only 25% of retail cost(probably because no one wants a blue Honda) I pulled the trigger.

I think it will actually look pretty good and it would have been a crime to put the scratched up plastics on with how nice the rest of the bike is.

Next will be installing the battery and then once the gas tank is on I can (fingers crossed) fire it up!
 
Installed the fuel tank and put in some fresh E0.

Turn on the key and can hear the fuel pump priming which is good, sounds like its pressurizing the system.
Try to start the bike, cranks no start.
Check for spark, good spark.

The bike will read trouble codes and then display as a blink code, did this and got a code for "IAT temp out of range"

I pulled the Intake air temp sensor to have access to the connector and back probed it.
image002.webp

image001.webp


0.279v is within the specified range so now I'm not sure whats going on. I'd like to check fuel pressure but no simple way to do it on this bike.

I cleared the code via a homemade dongle and a key cycle sequence I found in the service manual but the code comes back as soon as you turn the key on. However the sensor appears to be working correctly.

I left it like this for the night kinda stumped and decided to come back the next day with a clear head.

I came to the conclusion that the ecu isn't seeing the correct signal from the sensor but then after doing some research I realized this shouldn't cause a no start as when the signal is out of range it defaults to 31deg C.

I then cranked it a bit and pulled the plug, no fuel as I suspected. So then I wondered what would cause the fuel injector to not cycle and also the IAT sensor signal to not get back to the ECU and then it hit me and I felt quite stupid, I bet the connectors are the same I I hooked them up wrong.

Sure enough the connectors are the same and they are right next to each other so easy enough to make this mistake.
image004.webp


So with the connectors swapped top the correct position I cycled the key on, no codes now. Hit the button and fired right up.
It ran great, always nice to hear after having a engine apart.
 
Next was to get the plastics mounted. As mentioned previously I got a smoking deal on a set of new Acerbis plastics. Acerbis is usually good quality and is actually the OEM for several Euro brands like KTM and others but its always a gamble with dirt bike plastics.

The fit turned out to be great, I was impressed.

So were almost wrapped up. I had some OEM style graphics made up and should be here so to complete the look.
Also have a new shifter on the way and forgot to order new seat bolts as the previous owner had some hardware store specials on it(most of the plastics actually had non-OEM hardware so I corrected that)

So the next post might be the last in this journey.

Only other thing that's kinda on my mind is changing out the spark plug boot with a black one. Is that going a bit to far? What do you guys think? I hate how its the only red accent on the bike, I even powder coated the shock spring to change it from red to black.
 
I like that 1 bit of red, but it is your project. From this angle, it looks like it might be easy to damage if the bike gets dumped, or is there a guard for the front of the engine yet?

It doesn't really stick out enough to get damaged from dumping the bike unless it was to get caught on a branch or something. Its tucked away pretty good.
 
What oil did you put in it? Isn't that the most important part of this thread? :p
I put in Shell Advance Ultra 15w50 because I have a bunch of it on the shelf and currently no bike that specs it so just using it up. Planning to do a short OCI incase there is any debris from the rebuild.

Might switch to whatever it’s spec for after that, probably 10w40 I’m guessing.

It's been almost a full month since the last update but its now finished!

One last "fix", this plasitic piece around the gas cap was beat up badly and a bit of a eye sore so I picked up a new one.

I had a set of decals made that copy the OEM style to give it more of a factory look.

I keep my Ducati in my office to admire.

I assume you'll have to do that with the YamaHonda, since it's too nice to ride. 😁
 
It's showroom condition for sure right now. It's going to sting a bit seeing it get scratched up but I just have to remind myself I built it to get ridden, not look at it.

I get it.

I DO ride the Ducati too, I just keep it in my office to look at between rides, instead of the garage.
