2006 Honda CRF100F Refresh

[JWC86]

It's been awhile since a update.

Next up was the rear suspension linkages. Honda doesn't do great job here. They use plastic bushings that are known to fail even with low mile bikes. This bike doesn't appear to be all that well used and they already had quite a lot of play.

I replaced them with a needle bearing kit. The linkages themself I sand blasted and painted.

With the linkage installation comes the rear shock, this appears to be in good condition so I just cleaned and polished it up a bit.

Now the foot pegs could go on with the brake lever and shift lever. The peg brackets got the sandblast/paint treatment with everything else getting a clean/polish.

Moving to the fuel tank now, plan was to inspect/clean the screen inside the petcock.

Apon inspection I found the screen to be torn, then as soon as I touched it, it just fell apart so it got replaced with a new oring.

Carb got a OEM gasket and oring kit, air/fuel needle and new pilot jet. Everything else I was able to get cleaned up and reuse.

Air box got cleaned up, was missing the screw on the boot that attaches it to the carb, got new one from Honda.

You might noticed I installed some other odd parts: mud flap, chain gaurd, crankcase breather hose, kickstand, etc.

Installed the exhaust we previously sand blasted and painted.

Figured I'm ready to see if it will run now. Changed the spark plug out and did a compression check since I already had the plug out.
163psi is very healthy!

Installed the gas tank with new fuel hose.

So with the tank installed I added some fresh E0 and gave it a kick. Fired up first kick and ran great, idle was high so I adjusted that and it purrs like a kitten. I will restart on 1 kick every time I've tried since. Can't beat a Honda!

Looks great!

Moving to the tires now. I have a new one for the rear with a new tube and rim strip. The from tire is still good but I want to swap the tube as I think it still has the original .

You can see here where the front tire has slipped on the wheel at some point so this needed to be addressed anyways.

After getting the front tire back on with the new tube I noticed I forgot to install the new rim strip so I got to do it all again.

After the rear tire was on I installed a new sprocket. The sprocket bolts were all stripped out so I replaced them with OEM bolts.

Back wheel installed, rear brake hooked up, chain installed and adjusted, etc.

One of the adjusters was messed up and the nut rounded off so they got replaced with new OEM.

I Installed new steering stem races and roller bearings to replace the factory ball bearing setup.

Installed forks(with new oil and seals), bars and controls.

All that was left now was the fender, plastics, etc.

Here it is all finished up. Looking pretty good if I might say so myself.

Took it out for a test rip and it runs awesome, I had more fun than I probably should have.

I am having one small issue, fuel leaking out of the carb overflow. If I tap on the carb it stops so looks like the float needle is sticking. Will have to take apart the carb for a better look.

Looks terrific! I see the Yamaha is still in the stable. Will your daughter move up to this one? One observation: it’s amazing to me how ham fisted prior owners can mess up something as seemingly simple as a chain adjustment. I’m constantly amazed at how old bikes have fasteners ruined.

Yep, she has out grown the PW80 and her little sister (6 years old) has taken it over. Next time out the oldest daughter will get a lesson on how to use the clutch. Shes been around when I've been working on clutches so she understands how they work which might help her pick up on using it quickly. The Honda seems like a great bike to learn on, it will tractor me along at less then walking speed without stalling.

I agree, chain adjustment bolts I always see rounded off on pretty much every bike I work on. I don't thing they realize the rear axle is what holds the rear wheel in place. Those adjusters are just to help getting it in the correct position and squared up. Sprocket bolts disc brake bolts also always are stripped out for some reason.

I took the carb apart again and didn't see anything wrong with the float needle and it didn't really seem sticky in the seat but it is a pretty sensitive thing. I polished up the seat with "Never Dull" cloth on the end of a small nylon bristle brush in a drill to a shinny polished finish. The needle felt smoother in the seat. I put it back together and it appears to be fixed, no more overflow.
