Chef, are you going to haul it up North eventually? I am along the way (Northern Virginia) count on me if you need anything.

Thanks guys I am excited! Hopefully getting out of this mental ad physical rut. Yes 70cb750 that is the plan. To haul my k1 and the 450 up to upstate ny where it all started for him (his mothers house he grew up in) for the family party/reveal. Still have trailer logistics to sort out. Unsure if you can rent a uhaul utility trailer for more than one day

Good news. If only 2000 miles, shouldn't need rings?

cheftuskey121 · « **Reply #53 on:** January 22, 2014, 05:29:23 AM »

Bill said the top end is not currently on the engine, the engine was in a wrecked bike at only 2000 miles and I think the pistons were taken out. Still has to be built up, gotta go through it and refresh things anyway. I want it at fresh as I can afford for my dad so there are no worries on his end. He can do his own maintenance but I don't want him having to do any major work. I'm fairly sure the existing engine I have is toast. More than likely going to try and take it apart though....for science!

For sure cal, a machinist I am not. Its a little daunting truthfully, but once I get over this engine hurdle I have confidence in all other areas. Will begin restoring little parts/sub sections here and there so I don't big myself down. Biggest hurdle right now is money, trying to avoid funding this by myself...since I want it to be a family gift, but no one else has the passion or vision I guess. If I have to sell Fiona I will but I am hoping to avoid that :/

good luck with it chef...

Renting a trailer for multiple days should not be an issue. Heck, you might even find a local member that has a bike trailer you could use.

If they don't bike it's hard to instill the passion riders have for it.

Glad Bill helped out, A 40+ year old 2k engine is a real find.

not dead here guys, just not much to update. I got the carbs off and cleaned out. surprisingly easy. WAYYY easier than my K1 thats for sure. all the brass looks good but I am getting new float valves and new floats. have oem gasket kits on the way too. the floats don't have holes but I like precaution. all the jets look great. going to sodablast them soon and paint like my K1 carbs. the frame is almost bare, I need to get that so I can get that frame cleaned and painted. then that will be two things off the list! honestly the part stalling me most is money. I am going to make this happen though, there is no alternative. stay with me guys....its slow but soon it will be cookin

Yes sir they will be! The great thing about soda is it's very difficult to clog passages. Yes I will go through each passage though. Bill has the engine up in ATL. I need pistons. I think he said he found rings but I need pistons and wrist pins. At 2000 miles the bores should be well in spec right?

a 450 definitely should be as long as the oil was changed and the motor not thrashed....Larry

I'd suspect so. Can't you pull down your "stuck" motor and get this pistons evaluated?

Cal, I am trying to find NOS pistons to go with the new engine. figure if its gonna be fresh.... the stuck motor has 24k on them...and they're more than likely rusted shut. I may literally push this motor off a cliff.....too bad the southeast is flat. haha

If it has the cl exhaust you can also sell it to subsidize your build a little bit. They go for a pretty penny.

Now you tell me!!!.....where were you in 1971 when I was tossing a perfect set from my K3 in the dumpster?

754 · « **Reply #63 on:** February 09, 2014, 01:30:20 PM »

Dont buy pistons till you measure/inspect the bores. ..could be pitted..

rb550four · « **Reply #64 on:** February 09, 2014, 01:31:11 PM »

If things are really hard to find maybe you could add a 500T engine or top end to your list of possible parts
I have seen a few for sale on honda twins.net before but haven't looked lately,if you are a member there you can put up an ad in parts wanted.... haven't seen many in the Northeast on CL., I check regularly, just an idea... good luck.

http://jonesboro.craigslist.org/mcy/4320083297.html This is all I found down your way
http://hudsonvalley.craigslist.org/mcy/4275780802.html up my way ,450 and 500t for parts ...$500

That's all I could find up and down the coast

seanbarney41 · « **Reply #66 on:** February 11, 2014, 03:13:18 PM »

No replacement for displacement?...I think it's generally understood that the 500t is the exception to this rule...

cheftuskey121 · « **Reply #67 on:** February 11, 2014, 09:10:59 PM »

Bill` said the bores cleaned up nice with a honing and are in spec for stock pistons. on the hunt for some now. pistons, wrist pins, clips, cam chain, and gasket kit are on the list of things. then its up to ATL to build it with his help. lots of fun to be had soon!

Bill/BentON Racing · « **Reply #68 on:** February 11, 2014, 09:29:44 PM »

Chef, cam chain may be ok. Haven't checked, but good chance. We will need a m/link for it for sure!

cheftuskey121 · « **Reply #69 on:** February 19, 2014, 09:21:13 PM »

alright. not much in the way of pictures...but I have gotten some progress done.

cam chain and master link, standard pistons and pin circlips ordered. holding out for cheap wrist pins but cms has them for $80 shipped.....might have to go that option.

also ordered new front and rear DID stock rims, spokes, tubes, tires and wheel bearings.

frame is stripped and bare metal. just primed it today, will be painting tomorrow as well as the center stand. ordered tapered steering bearings.

swingarm is bare as well but I cannot get the bushings out for the life of me. I did it on the 750..these are stubborn though.

carbs are soda blasted, ultrasonic cleaned, have new OEM floats, and are rebuilt with OEM gaskets. painted the pump tops and bowls, left the bodies alone. these are ready to go.

uni foam material oil/cleaner are ordered to redo the stock airboxes.

I also ordered more bullet connectors from vintageconnections to freshen up the wiring harness.

things seem to be coming along. still need to actually build the engine with Bill, and have a ton of more parts to buy, as well as painting. its nice to have the ball rolling though. I felt stuck for so many weeks. tax return comes in tomorrow and its going straight to this bike. LOVE YOU POPS!

MoMo · « **Reply #70 on:** February 19, 2014, 09:53:00 PM »

Hope you get a healthy tax return as it seems like you are doing the ton with twenty dollar bills. Are the wrist pins that bad that replacement is necesssary?

haha momo, I sold one of my electric guitars I build on the side as well as finished a custom one for a customer. of course it helped that my brother finally sent me a lump of money.....it's his dad too!

I don't know as the engine is in Bill's hands. will have to follow up. I don't mind getting new pins, I can get some other stuff from cms is I need to. this is a no holds barred rebuild...it HAS to get finished at whatever cost. money will not be the issue here, I will sell whatever is necessary...time on the other hand, can never get enough of that!

MoMo · « **Reply #72 on:** February 20, 2014, 04:30:37 AM »

Good to see one of your siblings decided to chip in. don't blame you for the no holds barred build. If my Dad were alive and rode(which he didn't) I'd be doing the same...Larry

Stev-o · « **Reply #73 on:** February 20, 2014, 04:39:08 AM »

Good update, Chef. You are moving....

Bill/BentON Racing · « **Reply #74 on:** February 20, 2014, 04:41:48 AM »

I agree. My dad's 86. He doesn't ride, but he bought me my first one ! CA102(elec/start). Put over 8000 miles on it......a lot off road. One hell of a bike!
So yes this project kinda special.

Bill Wrist pins Im checking today, but I think Chef wants new ones.....going to have new rings( I had) pistons, clips, so Im not against it. Looked in chambers last night....you'll get to see a torsion bar!

And big roller in cases worn also.
