We KX85 Swapped a Harley Davidson | 2 Stroke Harley Davidson SS125 Build!

[@Ronin8451]

Here's a tip I got from an old guy who restores brass era cars and early motorcycles- use regular Pinesol ( not lemon pinesol!) In the tank for a few days and it eats all the rust and will be ready for the tank coating aftrr a wash out and dry. I exclusively use POR-15 tank sealer. It bonds the best and will never peel off!

[@markschlehr6911]

Ammonia! Pinesol is ammonia. Just the vapors will eat away all kinds of crap but it has to be outside or in a sealed container because the fumes will knock you over. And never mix with bleach products! Rinse thoroughly before the crap dries back onto whatever your cleaning. Ammonia is also the base ingredient in oven cleaners.

[@kevinsellsit5584]

Thanks for the tip Ronin. I am working on a V65 Honda that needs both tanks cleaned out and Ill try this method. I just wish it would hold twice as much fuel.

[@jhawk1985]

Por15 is awesome. I like that you can weld to it also

[@Ronin8451]

Pinesol will also clean dried fuel and clean carburetor too. I use it in a heated ultrasonic cleaner then rinse everything in hot water before drying it.

[@SocketSlinger]

That works but we always use lye and they always look new inside.

[@ericwilson2585]

When I was a teenager I used to have one of those, but mine was the SX175. I never got it running either, and it just needed piston rings, couldn't get any for it, and that was way back in the mid 80's. I squirted oil in the cylinder and it fired of a couple power strokes once but that's about all I ever got out of it.

[@Lord_Verminaard]

Can't ever feel bad about cutting up a frame on something that would have otherwise ended up in a junkyard. You are saving this one which is awesome!

[@MontanaPacific]

Add a guard to the exhaust. I see you guys finding a rock and sending it through the exhaust pipe. Good job on the rest. Keep up the good work.

[@paulshea2560]

I own 2 SXT 125 Harley dirt bikes 1975 orange and a 1976 black.They aren't the most powerful things lol but fun to ride.The 76 I've had since I was 15 and I'm 46 now and even when I was 15 @100 lbs it was a slow tank but still alot of fun to ride. I've heard of people putting sportster motors in them.The Aromachie motors are Italian and fussy to maintain I can understand a motor swap.The bike itself is mostly True Harley-Davidson though. A cool fact is that the SXT 125 Enduro ,(not to be confused with the SS 125 )was the only Harley-Davidson to come from the manufacturer with a Left side tailpipe. HOPE YOU ENJOYED THIS .

Oooooooh baby!….that bike should rip once you get that machine running. Yee-haw!👍😄 Going to be a whole lotta fun!😊

[@pokebass1]

A tip from a cross country dirt bike racer, those 85cc engines tend to load up and foul plugs when not risen hard. I don't really recommend trying to use them for street use. You may get lucky and that engine be one that doesn't have that problem, but the small motocross bikes are bad about it. A good 125 is great for lugging around and never fouling a plug, but the 85 will likely need jetted.

[@shrapnut7612]

@ .56 I thought you were gonna say "as fast as it ever should," nice vid, keep em coming. Thank's again.

[@davidschumacher52]

Don't feel bad about cutting the harley, I had one 35 years ago and couldn't get parts for it then so I sold it. Anyone really familiar with these will tell you that it was a POS when it was made and anything to modify it will only improve it. I do respect you guys for originally feeling guilty about cutting up a classic, and its only rare because they didn't sell well and they were not dependable..

[@Jalen_Knight8526]

This is an awesome and extraordinary build/swap. Love the video guys. Keep up the great work. “It’ll be fine” if something goes wrong these are the guys to fix it. I love y’all’s channel. Go CarsandCameras!!! 🏍️👍👏🤝🏍️

[@genebond]

Looking good. Back when I was young, I had a '69 Baja 125. I believe it was an earlier (and possibly better) model than the AMF labeled ones. I'm not sure when AMF bought Harley, but I think it was 1971 or so. I had no real problem getting parts in the mid to late 70's. I actually left 2 of them in the barn when I moved out of the old family homestead... Now it's a TW200 for this old man :)

[@RedneckSwede]

I saw an AMF Harley 50cc moped here in Sweden at a local vintage car and bike meet. It looked used and loved at the same time. This however, it's about to be ripped!

You need to build a frame table to straightening frames, you could use it on other things to.

[@dominicrichardson5546]

Glad you brought this bike back, very retro especially with that sticker on the fuel tank, love it

[@pyromedichd1]

I've restored old seat pans and rusted out AC housing in old Dodge vans back when they were made of steel using epoxy resin and fiberglass mat. You can even use cardboard as a form to restore the original shape and cover it with the epoxy/mat combination laid up just like one would make a boat. If you clean the rust on that old seat pan it could be restored very nicely using this method.

[@steby123]

That's the usual meme but the Aermacchi engines (the SS was an Aermacchi rebadge tweaked for the US market were decent for that ancient era and has some success racing. Vintage road and dirt racers run many "Aermacchi-Davidsons" to this day because they work well and vintage racers need machines reliable and simple enough to maintain on a budget. They gobble up most SS stuff at swap meets.

[@DaleErnieMichael]

You should try Naval Jelly for cleaning the rust out of gas tanks. Just dump a bunch in there and shake it up on the four wheeler, wait a half hour and wash it out with water. Repeat if it needs a second pass but it should be mostly gone with the first. There's also Evaporust which is dirt cheap and flows smoother but isn't quite as effective from what I've gathered. Both are better than hoping for the best with rocks banging around in there.

[@lindsey349]

You need to put the motor toward the back some the counter sprocket is near the swing arm pivit , or your chain tension will change drastically.

I'm waiting for the continuation, good luck to you!

[@jakelapointe8392]

Just so you know dents in the exhaust can really affect horse power and an easy way to get them out is to plug one end then heat the Dent up with a torch and put air in the other end so it balloons it out but be careful not to do too much or it will make a hole.👍

The way Charles was saying “scratch scratch” when he was putting in engine and exhaust parts in the frame😂 Also Ike’s segues are smooth and on point👏

[@brandon2076]

If you want to avoid headaches down the road, use Caswell 2 part tank sealer and nothing else going forward. POR15, Kreem, Redkote and all/any other 1 part sealers do not hold up and cause more problems than they're worth when they fail, it's harder to deal with failed sealants than it is to deal with any other problems you'd have otherwise.

[@markschlehr6911]

Here in the UK, a friend had one of these (a 1976 SX125), back in the early 1980's. Parts for these were non-existent even back then. There's more chance of finding a lawyer in heaven, than finding new parts for these today.

[@MrFlobot69]

For that seat that's trash, just an idea. Buy one of those cheap 20 dollar fiberglass kits and put some thin plastic over the bottom of the old seat. Make a mold. Put a couple more layers of fiberglass over the top of your mold after you've pulled it off the old seat and add foam and a cover to your mold. Idk just a thought. If it wasn't thick enough then maybe add some 3m window weld to both sides which is basically polyurethane.
