good to see another F.....seems like alot of us now...lol

looking good so far.

what are your plans for the bike now?

kenneyginter · « **Reply #26 on:** January 27, 2011, 06:15:14 PM »

RpBet, i got new rings from another member on here (tweakin) so im all set in that regard. I do need to do some honing tho. Hopefully this weekend. As for my plans for the bike, its slowly becoming a cafe racer. I am trying to put more of the money i do have into the engine and worry about the body later. I could use some suggestions on color and what kind of paint to use tho.

f2 are great and i am glad there is a community of us.

. seems like im one of the few on the forum from the east coast tho.

I do have another question for you guys tho. I recently purchased some air filters (replacing the old box with 4 individual ones) but i got 39mm. they seemed to small so i sent them back. does anyone know the correct size filters for the f2 carbs? i would assume its 42mm but i am not sure.

also does anyone have a set of 77 k spokes? i love to replace the corn stars with the spokes, love that look. thanks guys. more updates to come this weekend.

i think that you want F0-F1 wheels not K wheels

tweakin just went to spokes....check out his build

Im on the east coast too.
live on long island and go to school upstate.

well either way. love the spokes. love tweaks bike

brandEn · « **Reply #29 on:** January 28, 2011, 04:36:09 PM »

I love spokes to, but if you want to keep the dual discs up front your gonna need to swap the whole front end with a GL front like tweakin did. I am not sure if you could swap out for K wheels and spokes and run a single disc or not...

Retro Rocket · « **Reply #30 on:** January 28, 2011, 04:41:14 PM »

Why does he need a GL front end.? I have had twin discs on all my old 750's and never used a GL front......

Mick, Mick, Mick...

Did you ever have spoked wheels/dual discs on the bastard child 77/78F?

What BWJ is trying to say is for my swap when I tried to stuff a 76f hub and with dual 76f discs into a 77f front end it would not fit, no clearance! My understanding is that the later model F bikes have a narrower front end than the earlier models. I just said "F it" and went with a complete GL front end to match the 76f Hub (same as the 77GL hub) and be done with it, after throwing in some quality internals.

AHHHHHHHHHHH, i have the F0 {some call F1} its the only F bike i have owned, {owned a few F'n bikes as well

}, so any other twin disc K front end or early F would do as well.? Or even different model clamps because this is where the problem would be if it were narrower ..?

tweaks are your air filters on ur bike 42 mm?

tweakin · « **Reply #34 on:** January 29, 2011, 07:11:51 AM »

My air filters are going o be a different size than what you need since I am running the CR carbs. Check out www.dynoman.net for some good quality air filters to fit your bike or email Buzz (dynoman) to get the correct size you need. I can't remember off the top of my head what size stock carbs use.

i am in need of some more help. i am almost done putting the engine back together but when i rotate the camshaft the chain seems to skip off the sprocket every half turn or so. Its not a a lot but enough to concern me. anyone else have this issue? normal?

MRieck · « **Reply #36 on:** February 13, 2011, 12:43:49 PM »

The cam chain tension was set correctly?

kenneyginter · « **Reply #37 on:** February 13, 2011, 03:52:59 PM »

maybe a better question is which way is the engine supposed to turn counterclock-wise or clockwise? it only skips counter clockwise and also which side of the bike is cylinder 1 on?

i have figured everything out except one thing, the correct way to time the cylinders as i am not sure which way the cylinders read from. can anyone help me out?

sitting on the bike facing forward, 1-4 from the left? thats what i believe is my answer but i need to be sure.

Thanks guys

Not an expert on 750's, but that's correct for a 550.
BTW, why not download the manual from this site and be sure of what you are doing?

kenneyginter · « **Reply #39 on:** February 14, 2011, 04:25:10 PM »

tried cant seem to find that answer anywhere.

tweakin · « **Reply #40 on:** February 14, 2011, 04:27:24 PM »

Thats the way I have always read them. Do you have a manual?

yea but the thing that confuses me is the carb boots were numbered opposite and on the head near the springs it is scratched 4c. I just want to be sure.

tweakin · « **Reply #42 on:** February 14, 2011, 05:34:04 PM »

That seems odd, it is real difficult to be 100% sure with out seeing what is going on. I know a little but am far from an expert. I use the manual still on almost everything I do to the bike, just to double check. It is really easy to mess something up quick. If you don't have one look at downloading it here.

It is worth the time and effort.

Freaky1 · « **Reply #43 on:** February 15, 2011, 03:52:38 AM »

I numbered my boots to match the cylinders, 1 thru 4, left to right. They always fit good and it's one of the places I haven't had any problems.

RpBet · « **Reply #44 on:** February 15, 2011, 09:00:44 AM »

I have the Honda shop Manual "bible" and the Clymer. They read the cylinders are 1-4 starting from the riders left.

kenneyginter · « **Reply #45 on:** February 17, 2011, 08:10:02 PM »

thanks for all your help guys. on the the carbs!

Did you get the filters sorted out yet? I think that the inlet size on 750 carbs is 40mm, so the 42mm should be correct.

kenneyginter · « **Reply #47 on:** February 18, 2011, 05:13:21 PM »

yep 42mm is the correct size.

kenneyginter · « **Reply #48 on:** February 20, 2011, 04:34:01 PM »

best place for carb f2 rebuild kits?
