[@Patrick_B687-3]

One thing I’ve learned about other people working on my bike, is that a disturbing number of them don’t seem to care much about it. After using one dealer, and one independent, it became clear that I needed to learn on my own. So, for a year now, and 50 years old, I’ve been learning to work on my own HD. I find your videos interesting and enjoyable even though I ride a newer machine, but it’s all endlessly fascinating. I subscribed last year and watch most everything new that you film.

[@everettcalhoun8197]

Hi Mike, I think the 93 to 98 flh's are the best scooters to ride to put miles down the road. I have ridden knuckleheads to twincams and the evo's are the best. You can make them all fantastic but these bikes you put gas in them and service them and they'll run for a long time. Yah the cam bearing needs to be replaced but it's not like the shovelheads I've owned and tore them completely down and put them back together correctly. Currently putting a 95 flh together with an evo bottom and twin cam top. Love your spirit. Later my friend.

[@pacificmike9501]

You bet. They all have their place. When Harley came out with their FLH having its oil tank on the bottom, and several other features, they had a winner. Evo motors run for so many miles, they're great. And true; "Man does not live by one motorcycle alone."

Mike, I am watching your video on Lapping the Crankcases on a Evo motor with much interest. I just bought a '65 Pan and planing on restoring it to showroom condition, I hope. What skills you are demonstrating I am sure will help me as well. I suppose for any years as far as that goes. Not sure if you have ever referenced a '65 in your past videos, I will have to look but I don't recall all of them. Keep up the good work and details are always welcomed. The details can and could make the difference in something running ok and something running great.

[@pacificmike9501]

I haven't shown a '65 Pan yet. Haven't had one around lately. I was travelling kinda light in the old days and sold my '65 when I bought my new Shovelhead. That was a '77 Shovelhead. Still got that. One of my old buddies still has the '65. Another friend of mine has a '65. We do things as they need doing. We've shown my pan here and there on videos, occasionally the Knuckle. We'll just keep doing it. Hopefully, we'll show what you need.

[@jimbennett8015]

Instead if using paint remover on engine cases to remove paint I have found the best way to do it is to use baking soda in a cabinet blaster or just a regular hand held air blaster. Works really good to remove carbon from valves and combustion chamber in heads. Best is you don't have to worry bout medium getting left inside motor like glass beeds or other mediums cause soda just dissolves. I really urge people to blasting with baking soda.

Nice work Mike! I like the Evo motors myself! Question, do you have a suggestions on polishing aluminum with oxidized clear coat on it? Ik maybe some elbow grease and polish! But like as far as the polish goes and so on! Should I remove the clear coat? Just asking, again cool video! Good luck with all your work!

[@pacificmike9501]

It's a lot of work, but getting the clear coat off is the big thing. Different paint removers are more aggressive than others. Rubber gloves mandatory. Once the clear is gone, then you make it smooth. How you do that depends on how rough it is to start with. I'm sounding like a whiner, but when it's done, it's all worth it. Or, if you can afford it, and have a good one in your neighborhood, have a professional polisher do it for you. The cases in the video had factory black paint. I stripped them with paint remover. Now they are raw. I have way more hours in them than I wish to admit.

[@LyonhartZ2]

Hi Mike, how do you clean The cases so well? That is the cleanest I have ever seen!

It's hard work. These cases had original black paint in terrible shape. I did them with paint remover and later, "Scotchbrite." I not much for complaining, but, it was miserable and took days. Nice compliment though.

Hey Mike,,another good video,, I took the advice of "the big brother " responce,, found out about the oil tank from the book,,, next question is,,,, I am going to use my gas tank as the oil tank for the capacity,, so here's the question,, would it be better to use copper lines or a stainless type of brake lines for the oil feed and return and vent?

[@pacificmike9501]

Stainless is certainly more durable. But, it's also harder work. You'll need larger diameter than brake lines. We're talking 3/8 here. I've done it with stainless hard lines. Again, "a lot of work." But, always worth it if, when you're done, it's your idea of "cool."

Hey Mike, thank you for responding to my last question. I do have another on the subject of EVO crankshaft cases and shafts. This concerns whether I need to replace the timing side bearing. It is confusing in the manual - or I am just not that smart! I have a "green" crank and a series "2" case. With my best measurements my race measures 1.7510" and the shaft 1.250" According to the manual I should replace with a "blue" bearing?? Can I still use the current bearing as it is ? The current bearing and race has no pitting nor heat marks and I would say they were in good condition. Were I to change it should I also change the race? In other words can I just go by the clearance and "feel" of the current setup? I guess when checking the other side, the Timken bearing should be preloaded and checked for end play but if all looks well it should suffice - can the same be said for the timing roller bearings? Many thanks bud... Phil

[@pacificmike9501]

The way I look at it, you're there. I don't want to leave anything to "chance." The race should be lapped and a new bearing installed. I've seen a lot of people open them up and not replace the bearings. Measure over and over, then lap and replace the bearings. Peace of mind is what it's all about. The final fit is by how it "feels" going together. This is all about you and how you see it. If you're not sure, seek help of someone with more experience.

Those studs are a tight "interference" fit. You don't remove them if you don't have to. Treat them as per the service manual. Clean and oil the nuts as per their instructions.

I don't know where it's leaking, but that's how far you need to take it down. Not difficult, but must be correctly done. If you're experiencing a cylinder base leak, I suggest relapping the valves, a fresh set of valve seals, and a new set of piston rings. Again, correct according to the service manual. Torquing is very critical on an Evo top end. I am assuming the rest of the motor is in good shape.

Thank you first i like to said I learned A lot from you so the question is a have popping or back firing on slowing down it's on my 2003 dyna 88 twin cam you think it a gasket or a jet problem any help would greatly appreciate 😊

[@pacificmike9501]

Thank You. Not enough info. What's been changed? Has it been sitting too long? Maybe bad gas. If not, what changes have been made? Check the plugs. Is one light and one dark? If so, vacuum leak, either a line or a leak at the manifold. Gotta tell me what you're dealing with. The only way I knew it was carbureted, is you mentioned a jet.

I’m actually about take my engine apart as well as a second one I bought due to my pistons exploding in my 92 fatboy

[@pacificmike9501]

Wow. I hope you figured out why.

Hey mike are you applying pressure or doing like you would with sand paper and let it work with minimal pressure?

[@pacificmike9501]

It's light pressure.

Awesome video what kind of file did u use to get the rough edges thanks

[@pacificmike9501]

I don't remember doing that. I remember lapping with lapping compound.

[@loganpalmer3488]

Hey Mike I understand the 1340 and 1450 are basically the same but could you do a complete tear down and rebuild of a 1450?

[@pacificmike9501]

I generally work on older stuff, other than to help outa buddy once in a while. I'm a relic, you know. I generally think of engine displacements in cubic inches I just did the math. 1340 is 80 inches. I knew that 1450 is 88, a twin cam. If I had one, I'd rebuild it so I could like it. I built one for my cousin and it is an extremely smooth unholy terror. But again, I really try to stay with the stuff I like to ride.

[@loganpalmer3488]

@@pacificmike9501 thank you for the speedy response. is there a way to direct message you i have a few questions that you may be able to answer about my motor that I just can't figure out for the life of me.

[@efrainguzman6143]

Mike what grit of lapping compound your are using?

[@pacificmike9501]

They don't even tell you on the packaging much anymore. Fine or very fine does it.
