[@bigrednick100]

Just a few things. 1 always rotate the piston pin retaining clip to ensure it’s fully seated and so the opening doesn’t line up with the indentation on the position. 2. Why didn’t you just gap the rings in the cylinders on the bench and then install the piston? It would of been much easier. 3. Cometic gaskets come with updated torque specs for the head bolts. They no longer use the 90° turn method. Other then that it was a pretty solid video.

[@KnobleMoto]

Well since you asked: 1. If I could rotate the clip once it’s inside, that would mean it does not have any spring tension, and I would use a new wrist pin clip. 2. Because the light coming in my window generated a glare on the freshly machined cylinder that created a glare on the camera. So in effort of making things easier to see for the viewer, I did it on the bike so I could diffuse the lighting. 3. Cometic does have updated torque specs and they make a great product and I highly trust their engineering department. However if I give a spec that is different than the service manual, a bunch of self appointed video critics will get type-ee, and start lecturing about how I should not deviate from the service manual.

[@bigrednick100]

@@KnobleMoto I agree with all of that except the first point but to each their own. And you’re definitely right about people jumping on the manual bandwagon. The worst part is 90% have never actually turned a wrench and let’s say 8% of the remaining 10% have never done it professionally.

[@bryanmontgomery4050]

I think they have the torque then index 90° to keep people from re-torquing or hot torquing after initial build…. Just my $.02

[@BIG-xd6qb]

After the big bore kit do you feel a big power difference on the highway like top speed? Does it make having a 5 speed not so bad?

[@KnobleMoto]

Overall, yes. However I did the 510 cam first, and that alone made it pull much harder on the highway. Upped the top speed to about 118 from 105. I also dropped the commentator sprocket from at 25 to a 24. That helped it push the wind. The big bore kit turned everything up a few notches. Regarding the 5 speed: Twin Cams are like metric(Jap) bikes. Just twist the grip more and spin the snot out of it. The engine loves it. WITH the lower gear ratio, I would spin mine at 80+ all day long.

[@shawng7902]

Good video. I'm trying to figure out how to watch it though. Turn my back to the screen and watch it through a mirror? That or your engine is in backward I can't tell lol. Im thinking of doing this to my 88 real soon. I have it torn down that far, I should at least fix my rear lower rocker box while it's out.

How does the break in process work after doing a big bore kit. I’m doing a 95 big bore kit on my 88 and I’m getting lots of mixed answers on how to break in the rings?

[@KnobleMoto]

When I build an engine, I take it easy for the first 50 miles or so, then I ride the piss out of it. Somewhere in the first 500, I will wind it out on top gear to be sure the rings are seated. Start with conventional oil for the first 500, then 1500, then full synthetic and don’t worry about it.

I switched to gear cams before I had a KZbin channel. It is a fairly easy job. If you can do a big bore, you can do cams and vice-versa. You will need a few more special tools for cams.

[@megastick9324]

@@KnobleMoto all the head gaskets I’ve ever done from cosmetic have come with instructions for torque. It’s a 4 step with an actual torque value at the end. As a matter of fact their instructions are pretty adamant about doing it their way. Many hi-po shops recommend it also. That said, the original way, with 90deg turn should be very close. The issue is, with that method is a different gasket make up and it is with new studs, so the stretch is known and will be the same, with used studs, it could be off a bit at each one, and the compression of the gasket material, hence the known value for the last step. On such a mild build I seriously doubt you’ll have issues anyway. Just something to know for the future.
