Welkom
IMNSHO maintain this classic bike, and use it the way it was designed to be used. It's a great design, and you will only become less satisfied with it if you try to "improve it". I ride a KTM 990 SMT and when I get back on my R100S it feels kinda frumpy until I get used to it again. Then I'm totally happy with it.

Want to compare speed and efficiency against you Aprilla?

Set them up side by side with a timer. See how long it takes to do a valve adjustment, then decide which bike is fast!

Instead of spending two days in the shop working on the Italian slut, you'll be riding through Dinxperlo on the way to der fatherland on a seriously good motorcycle

Welcome aboard, a RS what else ? Maybe a G/S
I miss my 77 RS and my 79

Hello All, thank you for all you replies , have bin a way for some days, nice weekend at Spa Francorchamps, a big classic meeting, want to participate next year whit the RS.
I will do some modifications, but keep the bike appearance original.
Not like some bikes on the photo's , but I would not withhold them from you.

I will keep you posted on the progress, I will start working on the bike soon, yesterday on the way home the clutch started slipping, so that needs to be fixed anyway.

Hello Bor, welcome to Boxerworks.

Top choice, the RS. To be as nimble and fast as your Aprilia, you just need to ride your RS in the right place.
Super tight mountain twisties.

There is a current thread regarding handlebar mounted mc. You'll get lots of help here.

So nice to keep the RS as an RS. A seriously capable machine, in my totally biased opinion.

Thank you ME 109, never said I was compairing the Aprilia with RS, not a honest comparison, love riding both bikes.

Found the topic a bout he handlebar mounted mc. Thanks.

Welcome!!
Nice Bike!! From what I remember a '79 should pump out about 70 horsepower, so with the age, mileage, and the fact that you are taking the dyno reading from the rear wheel and not the crankshaft, I would say you have a quite healthy RS.

Rebbel, that is trough, normally you lose 10-15% from the crank to the rear wheel. So it is not to bad.

Welcome Bor.
The bike looks great. If you add the open keihens and dell's, it'd be interesting to compare the dyno run to your 55hp baseline.
Are you running 170 main jets?

Steve, thanks, Whit the dellorto's I will ad an K&N replacement filter in the original air filter housing.
Keep you posted about the outcome, will dyno it certainly. Want to know what the modifications did.

again thank you all, and I will keep you posted

Oh God, now you went and did it.
You used the "K&N" word....

It would indeed be fun Bor, to have both bikes. I was just being a cheeky bastard.

Keen to see what you produce with the RS.

Yes, I know, there is a lot to be said about them, pros and cons. But I like them

Well, at least you didn't say you like crash bars and intend to install a set...............yet.

Crash bars. I had those on my bike once. Took them off 'cause there's no way I wanted my bike to explode.
I think they exploded, it was something like that anyways.

Oo nooo, I think I already have crash bars on my bike..... those chrome tubes in front of the cilinder.... see pic on start topic.
Do you hit the pavement with them wiht serious cornering?

Hell yeah! That's the challenge.

Your type crash bars are no worries.
