Nice thread, It's incredible how well these motors held up over time. I have a two year old daughter and she loves coming outside and help daddy wrench on his bike. I hope this stick with her as she matures. How old is your daughter?

I'm building a F3 in a F2 frame right now, started last year and now she is almost exactly where I want it to be as my designated track bike. Bought the bike for $600 and now I'm at around $3,000 spent. I just need to do the final finishing touches on things I did not like during last season track and she is done. Seeing your project make me want to buy something else to start all over. A little scared of what the wife will say since I also have a crossplane R1 I also wrench, so I'm staying at bay.

These bike look great either with or without plastic. I built this bike a while back and I still miss her very much after I sold her. I keep buying back F series 2 and 3 every time I sell them, so my current project, I'll keep as long as I can. My first bike 15yrs ago was a F2 so I'm a little bias with these bikes.

 

I didn't realize there were blocks for the sides, thanks for letting me know.
I found them online, fairly cheap.
I used to carry tools, especially a 10,12 and 14mm sockets, in my car everywhere.
Could fix nearly the entire car with those, a needle nose, and some tape.

My daughter is 11. She liked to ride my old f1 with me and was excited when I told her I was picking up another bike.
I can't say she's interested in working on the bike, as much as she likes helping me so far, which is good enough.
I had some young male co-workers that watched me strip down and rebuild my 3000gt at work (it had a lift, air tools and such, but was not a auto related biz) and were completely clueless on how I did all of it.
Simple answer was, I just did. I learned by doing.
If my daughter can at least use some tools, let alone remember anything I tell her, then it might save her a lot of hassle or $ later. (or me hassle and $ later) If she just follows routine maintenance and has regular oil changes I will consider it worth it

I like what you did with the bike in the video, especially the A-team bit.

 

Not much new yet.
Took off the headlight, horn, gauge assembly etc.

Had to drill out a busted screw on the horn.


I put the valve cover back in place for the moment, and will check valve clearances later. I started looking at oil leaks.

The valve cover gasket doesn't seem bad. But seems to leak either way.
Not sure If I want to clean it up, add a thin coat of sealant and call it good enough, or get a new one. I may try adding the thin coat for now, and see what happens down the road. Cheap I know...
Depends on if I decide to paint the motor.

The oil leak I originally thought was from the oil pan, instead seems to come from the water pump shaft.



I'll pull it later tonight, but it seems to be the most likely spot.

 

I found a 97 F3 for sale for $375. Going to take a look at it tomorrow.
Rebuilt title. No carbs, no fairings, no front rotors.
Might be missing some other small odds and ends.
It has 30k miles on it.
If the forks are in good shape, it would keep me from having to get new seals for my current forks, plus a slight upgrade to the cartridge style springs, right?
Basically, I'm hoping that all the small things I was about to buy, like new wheel bearings, fork seals, brake pads, rear rotor, are all ok on this bike.
Wheels seem to be in good shape, as are tires.
I need the stator cover, passenger foot pegs, this seat is better than mine.
Extra nuts and bolts are always handy.

The bad news, other than no carb, is a reported rod knock from piston #1.
Current owner bought it like this, just for a few parts. He said he heard the knock, but no one seems to have bothered pulling the oil pan. Could be bad bearing. Could be bad cct. Lot's of could be's.

If I could take some parts that I need for my current build, and sell the rest for what I have in it, then I would be very happy. But no carbs and possibly bad motor make it a tad more difficult or at least a longer process.
Either way, I should be able to part out the bike for a few hundred over time.
I'll post up here once I've seen it...or bought it.

 

I ended up buying the f3, and picked up a few fairings as well.
I'm going to strip it down as well and write about what I find in another thread in the f3 side, probably.
Overall it is in better shape and more complete.
It lacks the f3 airbox and carbs though, and I need to find out if there is an issue with a bad rod or main bearing.

If that motor is good, then the f3 will be the bike I focus on and the f2 will be parted out, mostly. If the f3 motor is bad, then I MAY swap the f2 motor into it's frame, but this presents a problem since from my understanding he f3 carbs had a TPS that the ecu and wiring harness need.
I'll figure this all out as I go.
Maybe I'll just take what I need from the F3 and part out the rest to earn some $$ back.

 

I'd be really suprised if it had a bad rod or main bearing. That's just extremely rare for F2/F3s. There are several other things that I'd guess long before that. Let us know what you find.

 

I don't think it's a bearing either, but I am biased.
I drained the oil, no flakes or sign of bearing material, so at least I doubt it's a SPUN bearing.
Also, the head looks newer than everything.
It's shiny, the valve cover gasket looks new. The intake valves and guides seem clean and in good shape, EXCEPT one valve has a bit of rust around the edges.
I turned the cam chain and heard the sound of a valve snap shut, or open.
Just a quick "*****" type sound. Might of been sitting for a while.
I plan to take the valve cover off today. At the moment I'm leaning towards something up top being wrong.
It's just really cold and wet outside and my garage is drafty.

 

I gambled and lost :P
It's a spun bearing.
posted in the f3 section for future updates on it.

My carbjetkits.com kit cam in today.
It's an inexpensive and basic kit.
It comes with enough washers to add two additional "shims" to each stock needle.
I used their jetkit calculator. I don't know how accurate it all is.
In my case, since the bike currently has NO muffler, and I only plan to add a glasspack, I chose the "Exhaust System: Fully open, unbaffled Exhaust system" option.

So my kit has four Main jets size 145, four Pilot jets size 40 and 2 shim for each Slide Needle.
It does not come with the extras, like a new needle with clips or new springs, or new allen screws to replace the phillips screws.

 

I had a "GP" slip on off eBay on my bike and I ran the jets meant for a full system. It took some old fashioned butt-dyno and spark plug tuning with the needles and mixture screws, but it eventually ran great once I got it dialed in.
