Best Bang for the Buck?

[mmattockx]

OK people, we are digressing a bit. So, barring me finding a decent 1150 engine for a good price I am going to stay with the 1100 and look at tweaking it.

With the amount of experience/knowledge here, does anyone know what I can expect from my 1100 with a set of RS36 carbs and a drop in cam? Considering it is street driven only is breaking the crank a very real possibility or not? Do I need an HD clutch basket or is that a nicety to be installed when the OEM basket gets tired?

Now back to our discussion of driveline losses...

even ms. daisy needs an HD basket....
and your 1100 will be happier with 34mm RS miks.

of course the black ones are faster for the 1100's

That include '82s that have been painted black (like mine)?

How about a bottle of giggle juice and button for that extra ummph.

We touched on Nitrous in a related thread, and most folks don't want temporary laughs.

Somehow I thing that black beauty is only skin deep.

As the paint peels off, the bike gets slower. Time for a spritz.

In MY book, a welded crank & heavy duty clutch hub are MANDATORY!!! I also use 750 oil pump gears in all of my motors. I build everything overkill & then have no problems.

Okay, if (when) she has to be opened up. But do you think I (my mechanic) should do those things now?

I mean, if I were to get the crank welded, I'd really have no excuse not to go big bore. And drop an extreme cam in. And port and polish the heads. Which would require a top end oiler. And a new wife.

We're talking about literally hundreds of dollars.

The carbs themselves don't really add power. Maybe a little if your stock carbs were creating a restriction. But what they do is give you the ability to match the fueling needs of the motor as it demands more air/fuel. You will get more power from a performance cam, but I don't know how much, and of course there's dozens of different cams out there.

I've asked these same questions, and there's a lot of different answers. What I have heard over and over is that the sum of the parts is less than the whole as a tuned package. And every motor is different when you start getting down to the fine points. As in, you might see 7 more HP with cams, and 3 more HP with carbs, and 10 more HP with a big bore kit individually. But in the right hands, and with careful tuning, those mods add up to 30HP gains. This is just an example with made up numbers. I think I adapted the video game theory of modifications after playing some vids. Yes, it doesn't work that way in real life. I knew this before, and know it now, but it's easy to adapt that ideology from the games. It was Forza 3 I think.

For a street rod like you're thinking, I don't think you need a welded crank or clutch basket. What you WILL have is more ability to break those weak points once you start cranking up the available power. With great power comes great responsibility. You can ride around all day with 200HP on tap and never use/need it. But if you do use it, those are the things it's going to stress the most.

I personally would love to see you do those two mods. Even more, I'd love it if you used some sort of metric to gauge "before and after". My tool of choice was 1/4 mile "Late Night Drags". For $29 I got as many passes as I could take. That was 10, and I would have done more, but they closed. Stock 1100 motor with airbox and V&H street megaphone netted me 11.5 at 118 mph.

Check out page 2 of this guide. Especially look at the [1-7] notes for modified engines. I knew I was going to be doing 3-7 in the future, so I opted for the RS38s.

RS36's gives 3 tenth's over BS36mm with st.3 jet kit's on a stock 1150 with pipe.
clutch basket is mandatory.
have you ever had one blow up between your legs...not a pretty site.

CivilRock, you need more experience before you state what is & isnt. 36 RSs are good for 10 hp by themselves on almost EVERY motor I have ever put them on. The one true thing is that the SUM of the CORRECT combination is where the power really comes from.
