A humble F2 build
« on: January 10, 2011, 11:03:53 am »
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.

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.

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)

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.

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.

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.

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.

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.

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.

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?

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.

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.
