Specializing in performance Harley Davidsons.
Hey I want to take this opportunity to kind of describe where we go over a couple of different things and what I So what I want to do is start talking about, first thing is going to be their piston design. I really This is a Y-Score piston, they make it for T-Man Performance and it is extremely nice work. So but really what I wanted to show So their cylinders is a stock Harley cylinder and then they have a real nice jig and a real nice setup to go in there and they bore out the factory sleeve. So if you can see right here the sleeve is very thick then it has this little square part right here and that square part is to keep the sleeve from spinning. Now I've never heard of them spinning but that just goes to show you the details they go through and extensive quality of work is to make sure it doesn't spin and the reason why you don't want it to spin is because all this needs to stay in its location so it's very important that the sleeve itself does not spin but if you notice here this is a factory one you can see that the sleeve itself is very narrow compared to the T-Man one and here's another cylinder a little bit thicker and this is a very well-known brand that we all love and use and everything so I also want to take this opportunity to show you the difference on this big part of the cylinder. Now if you notice the T-Man cylinder is taller and that helps us with keeping the piston square to the bore and keep it from rocking as the piston is trying to go back up it keeps it really nice and straight and keeps us the rings straight as well. Now here you can see that this is a thicker and it's only because this is a stock 114 this is a 128 cubic inch and the T-Man is a 131 but one good thing about T-Man doing this is I have an old cylinder here that I got from Randy over at high performance and if you notice this part here is narrow than this part here so that goes to show you that the factory cylinders and sleeves are not centered with the bore and centered with your mounting holes as well so this system right here is straight with the bore straight with your mounting straight with your engine case and you're piston and rod going up and down correctly 90 degrees and keeps everything really nice and tight and everything so this is one of the reasons why it's very important to have a cylinder that's going to hold up to the pressure as well and keep everything nice and true and straight. Guys if you have any questions regarding this feel free to give us a call or call T-Man performance they're extremely knowledgeable they've always helped me out
