2020 Honda CRF110F Refresh

[JWC86]

Next step is the throttle body.

I fully disassembled it and cleaned everything thoroughly.

All freshened up

And installed on the bike.

New rear sprocket and the "bump start mod" which allows the bike to be started in gear.

Your all caught up now. The plan is to go through the wiring harness next and start plugging in sensors as they are easier to get to before the airbox and frame go on.

Edit: bonus before and after picture(not a great before pic)

I didn't feel like messing around with wiring last night so I just put together the airbox that I had cleaned previously.

Here's some before pictures.

After a little elbow grease.

It cleaned up great. I oiled up a new filter and installed it.

As long as you're right there, does RCC offer a turbo kit for it?

I think a RCC Turbo would weigh as much as this engine lol

Are you going to let your kid ride this? Looks too nice!
My two boys tend "round the corners" off of almost anything they ride/use... I didn't realize we had erzberg hard enduro level of terrain at my house, but that's what the bikes look like they've been through after a weekend!

They sure will be! This one is for my youngest girl, the girls seem to be pretty easy on the bikes, far better than I was(am) on bikes lol.

I'm actually more worried about my wife riding it, she loves ripping around on mini bikes and has zero fear...

So continuing on with putting off the wiring I decided to go ahead and put the engine in the frame, or in this case the frame on the engine.

First I installed this "frame brace". This more evenly spreads out the force applied by larger riders. It bolts to the frame and the motor and rest on the frame in another place.

The powercoating place did a great job on the frame.

This area was full of surface rust before:

Looking pretty good.

I had the local decal shop make a new replica VIN sticker. Trying to keep that factory look.

You might have noticed the exhaust head pipe is on also, that got it's own transformation.
It had a lot of baked on mud.

The sand blaster made quick work of the mud and then I painted it with VHT exhaust paint, I've used it on a few bikes with great results.

I had the heat shields powder coated with high temp black.

The old hardware was in really bad condition so I picked up new.

What specifically did you use on that snorkel tube? I've had that before on bikes and swear it's a special rubber mold growth or something.

I know exactly what you mean, I’ve seen the same thing many times, typically those snorkels have a brown that won’t come off no matter what.

On this one I used a product I got from a profit sharing program at work.

“CRC Heavy Duty Pro Strength Degreaser”

I’m not sure if this stuff is the secret or if this particular tube was just easier to clean but it took very little effort to get it clean, just sprayed it on, hit it with a brush for 1 min and rinsed off clean.

After a long break over the holidays I've been getting back to the little Honda.

It was time to get it off the work bench and onto the stand, It needs the foot pegs to be secured to the stand so I started with that. The originals were all bent up so I picked up some larger ones to replace them.

Forks:
The power coat turned out great on the fork lowers.

New OEM seals and back together.

The kick starter was very stiff to swing out so I took it apart and cleaned everything up, greased and reassembled, works as it should now, gave it a good polish also.

Doing some small things like these little brackets got sand blasted and painted.

Nice work - Good on ya mate as they say over yonder !

Had the triples power coated also.

The bearings were notchy so replacing them with roller bearings, I like to convert all of these bikes with ball bearings to roller bearings anyways.

Pretty simple on these bikes, you just need the "nut" from a CRF125F as it dosen't have the taper in the black plastic sleeve that would be a clearance item if you tried to use the stock one.

Here's the part #

For installing the races I was glad to see my motion pro tool had the correct size for this bike, this sure makes it nice.

Tried installing the lower bearing on the stem but my tool for this was too big, hard to see in the pic but it hits the cage rather than the race.

After doing some measurements and digging through my scrap metal bin I came by the 12ga "case gauge" which I haven't used since my competitive shooting days. The OD was perfect but too small ID to fit over the stem.

It took forever on my small hobby lathe but I was able to bore it out and then use it to get the lower stem bearing installed.

Then I was able to install the tipples and forks!

Good job!!! nicely documented with grate photos...

Thanks, funny you say that since these last too posts I used the "medium" file size rather than the "large" option when I emailed them to myself and they look really grainy so I'll be going back to the large size option.

Also a little progress update, The wiring harness had a lot of electrical tape all over it so I had a feeling it was hiding some sins under there. I tore into it and it was quite a mess. Having built a all new harness for one of my other builds (KTM 500) and speding over a hundred hours on it I didn't want to go that route if I didn't have to.

I was able to source a OEM harness from Japan but it won't be here for a couple weeks. Thats fine thou as still lots to do. Currently working on the wheels/tires.

Also waiting on some bushings for the swingarm, had the wrong ones sent to me, expecting those anytime now. Then I can start on the back end.

 

[JWC86]

Wheels and tires. I cut the old tires off with a zip disc, haven't tried that method before but it worked great, I little bit of surface rush inside the hubs that I cleaned up with a wire wheel on a die grinder.

Installed new rim tape, rim lock in both wheels, heavy duty tubes and starcross 5 tires.

After the tires were installed I used steel wool and polish and got the wheels shined up.

The front brake was seized up pretty good, could barely move it. Pivit points were just rusty, cleaned everything up well and grease and good as new. The previous owner also included new brake pads so I replaced them also even thou they were still at around % left.

Polished the brake arm and bolt heads also.

With that done the front wheel was ready to be installed.

 

[JWC86]

These bike come with plastic bushings rather than swingarm bearings. Mine were toast and they are known to wear out quick. I found a company that makes a kit to convert these to a double ball bearing setup so I went that route.

The swingarm with fresh powder coat.

About to press in the bearing sleeve.

I even remembered to put the chain slider on before installing the swingarm.

I will also need the rear shock to install the swingarm, I disassembled it, cleaned and polished it and had the spring powder coated black.
Before:

After:

And installed, starting to look like a motorcycle again.

You guys are caught up again. Next will probably be getting the rear wheel ready, it needs bearings, sprocket and the brakes done as well as some more cleaning. Also the new wiring harness should be here soon so I will be able to get everything wired up, then lots of other things can happen.

Thanks for following along, it's been fun so far.

Enjoy following the work, nice details.

The rear wheel bearings had play, I knew this when I bought the bike. I pulled the bearings and installed new OEM bearings and spacer sleeve.

The grime in this area on the hub was bothering me, its a small area and hard to get into. I found one of my small dremel wire wheels would fit in there.

Before wire wheel:

After wire wheel:

Certainly looks better but I wasn't satisfied with it. I attempted polishing it a couple different ways but nothing was working well.
Then I remembered I had some "Engine Enamel" that's almost a exact match for the Honda grey paint.
I used the old dust seal to make masking it easy and laid down a few coats.

Looks much better, also you will see a new rear sprocket and bolts.

On the other side of the wheel I completely dissembled the brake components, cleaned and greased everything, the previous owner also include a new set of rear pads so I put them in as well.

Finished it off with a quick coat of paint and polished up the metal bits.

With that done it was time to install the rear wheel and started to hook up the brake.

One of the chain adjusters was mangled up bad, new OEM part was only a few bucks so I went that route.

The brake lever got powder coated as well.

I'm looking forward to seeing it on display in the living room, as it will be too nice to ride.
