After seeing so many great project builds of the F2, I decided to take on my own endeavor. I'm sure everyone knows it’s a lot easier to take a part than it is to put back together. In the process of tear down I took it upon my self to snap a bunch of pics, which will hopefully help me in the rebuild.

I'm not sure what the end result will be, but I want it to somewhat stock. I bought this bike, because I really liked the way it looked, so I hope to keep it that way. I just want to clean it up and replace aging parts.

Wiring harness, and shocks are off.
I'm open to any and all feed back.
Right now I have no money set aside for the build, but I could always sell one of the kids, probably the one trying to ride my bike after I told him not to.

Awesome, another F2 build! Looks like you have a good helper there to, pretty cool if he is interested. My daughter 3 and 6 have no desire to help in the garage unless they are helping with color choices, which always ends up being pink, lol. Some of the best times while I was growing up was helping my dad wrench in the garage on his old hot rods. i look forward to watching your progress.

Thanks Tweakin.
Your build was among the ones that prompted me to go for it. Since I bought the bike little things here and there would break down. I thought to myself it's time to get my hands dirty, and find out what makes her tick. I have two boys that are also 6 and 3, and daughter thats 2 months. I think this be good for both the boys and myself.

Sweet, always like watchin builds especially with these F models. Man take a ton of pics. That will help. Also I have some stock parts from my build I don't need. Not all of them are perfect I guess it just depends on what you need. Thanks to tweakin I have a whole freshly powdercoated front end I need to sell. Forks, trees, and brake calipers. The forks just need new oil and seals but are completely tore down and ready to assemble.

noahspop · « **Reply #5 on:** January 10, 2011, 12:16:58 PM »

Thanks BWJ. I also follow you build too.
I also voted for the exhaust thats in the lead, so far.

brandEn · « **Reply #6 on:** January 10, 2011, 04:37:25 PM »

Thanks for voting! The sidewinder has been eliminated due to ground clearance isuues. So that pretty much makes things easier for me.

I've decided its time to take the motor out. Just for the heck of it I put the bike up on a milk crate. This seems to have the same effect that the center stand does in regards to support of the motor. I have removed the portion of the frame above the valve cover. I have removed the two front motor mount bolts. I have loosened all the motor mount bolts. They are ready to slide out.
I'm at a point were I want to do this on my own. I was told the best way to remove the motor was to lay the bike on its side, remove the bolts, and slide the frame right off.
You guys have any better ideas? In the mean time I will look through the forum to see what other members have done.

noahspop · « **Reply #8 on:** January 12, 2011, 01:15:36 PM »

I love it when I answer my own questions. I'm pumped now.

I accomplished what I wanted to do with the bike before I started the new semester, which was to strip the bike to the bare frame. I will say one thing, I'm glad I took the bike apart, because it seems this whole time I was driving a death trap.
Bent front fork (see pic)
Cracked stator cover (see pic)
Clutch cable (broke as I was attempting to adjust it for removal, no pic)
Many rubber pieces and gromets with minimal life left.

I threw my gloves down to go help the wife and when returned they were throwing the horns (see pic)

Thanks tweakin for the hook-up. I have along road ahead of me before I can put em in. I couldn't pass up the sweet deal.

tweakin · « **Reply #11 on:** February 01, 2011, 04:34:04 PM »

I'm stoked you will get some good use out of the carbs. I had them already to go then I decided to go with the Cr's. Although they have been bench synced, I would still vacum sync them once you get the bike competed.

noahspop · « **Reply #12 on:** February 01, 2011, 04:40:28 PM »

Yup I plan on doing a proper sycnc. I'm now in the process of gathering all the frame parts together, so that I can get a quote to be powder coated.

noahspop · « **Reply #13 on:** April 14, 2011, 04:26:24 PM »

This semester has been crazy, and of course money is tight. I got me a set of used pistons, a used head, and cylinders from Big Bob. I have new hardware on the way, and I'm saving up to get some new to me front forks.

I'm kinda juggling two portion of the rebuild. Getting the original engine back together, and getting the rest of the bike pretty again.

I've opted not to go the powdercoat way, due to money. I think it would be more fun if I were to strip it, primer, and paint it myself. Oh good times ahead.

brandEn · « **Reply #14 on:** April 14, 2011, 04:42:14 PM »

I wondered was what going on with this build. If you need forks I have a set off my F3 with fresh black powder coat I don't need. They are not built up though but everything is there. If your interested PM and we can work something out. I have the trees and brake calipers as well as some brake pistons. All with fresh powdercoat.

noahspop · « **Reply #15 on:** May 28, 2011, 11:37:24 PM »

I opted not to powdercoat. I'm going to primer and paint it instead. I suppose money talks. Hopefully I'll get the ball rolling this summer. Most of the work will be top end work.

Good looking build, keep up the good work!!

noahspop · « **Reply #17 on:** July 26, 2011, 08:21:16 AM »

I finally got the valves out of the used head that I picked up. My next step is to clean up the head and valves. Fun stuff.

noahspop · « **Reply #18 on:** February 11, 2013, 04:18:16 PM »

Wow, has it really been that long since I posted on my build?
How time flies.
I want to thank brandEn for gettting me the parts I was in dire need of.

I did clean up my valves, and I now have my engine in position to have my newly acquired connecting rod put on.

It seems these days time is worth more than money.

I noticed that one of your fork tubes was bent. Did you take some measurements of the frame to make sure it's straight?

That is a nice build you got going on there. Keep it up.

Do you think it would actually effect the frame that much? Hmm. I'll have to look into it. I know visually everything looked fine.
Thanks for bringing it to my attention.

noahspop · « **Reply #23 on:** March 04, 2013, 01:27:48 PM »

I started to split the case this weekend, something I've been dredding.
I pulled the oil pump/filter and this is what I found. See Pic.

When I had originally drained the oil there was no metal (busted valve/piston) flakes, but now I realize I have my work cut out for me. As if I didn't know that already.

brandEn · « **Reply #24 on:** March 04, 2013, 05:31:56 PM »

Yikes!
Probably time for some new bearings!

RAFster122s · « **Reply #25 on:** March 04, 2013, 05:47:34 PM »

As far as forks go, Forks by Frank is a great source for new fork tubes. The internals can be cleaned and reused as they usually aren't damaged when the slider part of the fork is bent. Best to check the frame over with some straight edges and measurements to ensure the frame isn't tweaked before you put a lot more time into refinishing it.

Hate that you've been finding the junk that you have...

Once you have her back together and sorted you will know she's solid and after working through any tuning and care issues will have a solid reliable bike.

Hang in there.

noahspop · « **Reply #26 on:** March 05, 2013, 09:57:30 AM »

Thanks for the encouraging words David.

I've already secured a set of used forks from a fellow Sohc4 Member.
Thanks for the lead though.

Branden-
Where should I install these bearings? I'm still a newby.
Any type of diagram would be helpful.

noahspop · « **Reply #27 on:** March 11, 2013, 10:11:27 AM »

I was able to split the case this weekend, and finally got access to the damaged rod.
I noticed a bit of residue at the bottom of the case. Everything else looks really good. I'm happy about that. I'm gonna attempt to take old rod off (challenging so far), then put new one and, and put case back together.

I was so happy to split the case, even though I had been dreading it.

70CB750 · « **Reply #28 on:** March 11, 2013, 10:38:46 AM »

That is a one farked up rod, you got there.

noahspop · « **Reply #29 on:** March 14, 2013, 01:37:40 PM »

I think I found the problem.

I got the old rod off, and the new one one. Baby steps.

RAFster122s · « **Reply #30 on:** March 14, 2013, 01:55:10 PM »

Wow, might have tried to compress some fluid in that cylinder... Check your crank carefully for signs of damage

noahspop · « **Reply #31 on:** March 26, 2013, 08:49:05 AM »

The replacement rod is in place. Case is put back into one piece with all the 10mm bolts in the right place. So far so good.

noahspop · « **Reply #32 on:** April 05, 2013, 01:50:08 PM »

So I torqued down all of the bolts on the case three different times because it seemed snug when I tried to rotate the cam. Everything goes smoothly, but snug. I'm just wondering if this may be an issue in the future. Everything on the inside looked clean and in place.

noahspop · « **Reply #33 on:** January 01, 2018, 08:31:36 PM »

The engine should have little to no resistance when spinning it with a wrench other than the friction of the rings on the cylinder walls. Especially if the top end is removed. It is crucial to split the cases again and check all your bearings. You had a lot of metal running through your engine. Take it all apart. Blast all the oil galleries out with brake clean and compressed air. Thoroughly clean the oil passages in the cam towers. Have your crank for checked for straightness. Plastigauge the rod and main bearings and order new ones accordingly. You dont want that thing to run in its current state. I lost a head and cam due to a blocked oil passage. Its not fun breaking a cam in half on the freeway...

noahspop · « **Reply #36 on:** October 16, 2023, 04:33:55 PM »

Still have the bike, and I still love it just the same. I recently put parts in different containers to help keep everything organized. Feeling very motivated to move forward with the build. Gonna try and throw up some pics of the work area. Wish me luck.
