Re: My "new" old Bicarburatore

Hugo, you will be surprised, just how much "give" there is in the fender.
Those small mm differencies, will easily be pulled Down, by gradually tightening the bolts - and I am quite sure this method will leave no "gap"...

Re: My "new" old Bicarburatore

Lars is right - so dont shorten the stay too much - in fact I would stop at 25mm. Why? Because your seat has a somewhat wrong position, horisontalwise. To present a smart look, such a seat must never "hang its end downwards" ! It would look much better, if the libelle in your waterpas had the same p...

Re: My "new" old Bicarburatore

Solved, if you just move the silencer some 5 to 8 mm outwards - no one will notice it...
Or, like I did with my bicarburatore - used a hammer on a round socket to make a small "dent" in the innerside of the silencer.

Re: My "new" old Bicarburatore

I apologize.
I had the impression, that the silencers already came chromed from the old stock.

So, naturally they now have to be chromed - & I hope you know a really honest and good chromer.
Here in Denmark, just two decent chromers are left!
Both very expensive, very good.

Re: My "new" old Bicarburatore

Hello, Rudolf - nice to hear from you! You must have misunderstood what I wrote to Hugo... I never asked Hugo to paint his exhausts. I just asked him to try to polish his N.OS. alreday chromed silencers, in order to see how good they could come up. You know, sometimes one can get extraordinary resul...

Re: My "new" old Bicarburatore

Still a VERY good Price! But how can you know if the quality really is perfect? Because every newly chromed item always looks "like a million". The deeper quality will normally just show after, say, one Winter. Chrome jobs simply are a matter of trust!! You have to go to the internet, and search for...

Re: My "new" old Bicarburatore

Real high quality chroming is VERY expensive! Because the chromer first have to take away the old chrome - then polish, and subjet the item to numerous layer of copper, to make a durable base for a heavy layer of chrome... You can ofcourse get cheap chrome "everywhere" - but it wont last long A dedi...

Re: My "new" old Bicarburatore

You are right Hugo - chromers hate carbon & oil!
You mention, that the two silencers are new?
So why not try to polish them, and see the result...

They may come up beautifully - so you save the chroming expence.

Re: My "new" old Bicarburatore

Any garage with oxy/acetylene torch can heat the centrestand legs to red-hot - so you can bend the legs as you prefer... So, instead of making welds to the silencers - follow my SIMPLE advice, and make two alu. hangers, just to see how and where you need to have made the permament welds. By doing so...

You are almost there, Hugo! I am certain about, the situation you lust for, is to be sure the motor runs sweetly, & the gears will shift OK - not to speak about the thing beeing "oiltight" after all. But welding, and especially chroming (expensive) - can be very TIME CONSUMING! What you simply can d...

Re: My "new" old Bicarburatore

Hugo, I believe you remember the very l-o-n-g thread about the oil content of the gearbox? Back then, a lot of members wrote about just how much oil they poured in their gearboxes... In your situation, you should simply try to let the content be at 3/4 litre - just to try how it Works, smokewise. As...

Re: Setting points and ignition. But how is your "Abriss"?

Hi Hugo - Lars is a most clever guy - and his explanation about dwell angles is spot on! But I guess, your brain was on the verge of exploding... The good thing about this dwell, is the fact that the RUMI Factory already did what they thought would be correct, in the mid fifties, by fixing the flyw...

Hugo, it looks as you have done all Things right, relating to ignition & carburation, and the motor seems to be pulling strongly - BUT - it four-strokes intermittently, and I am afraid it is because of gearbox oil, sorry To let you try to get firm evidence, if it really is gearbox oil, you could sim...

Re: My "new" old Bicarburatore

Good morning, Hugo! I am 95% sure of, new plugs will cure the problems... If not? - here comes a simple solution about how to find out, if the float level in the floatbowl is too high. With engine running, the bike in third gear, velocity around 40 Kmph - motor warm - you shut the petrol petcock! By...

Re: My "new" old Bicarburatore

If the only change from before, is the floatbowl, then you should take a good look at the float & the floatlevel. You have a motor "running rich" - and this can almost just stem from the floatbowl! So, Check the petrol level of the bowl. I cant believe, a "wrong" ignition setting should let the moto...

Certainly yes, Hugo, your results are confusing... A good idea, obviously, is to install new plugs - but why not try the Iridium type from NGK? Giving me super results. As I had a Bicarburatore, together with a Corsa, you may use my settings, because the motors in question are more or less comparab...

Hugo, I hardly dare to say it...
But why not use the stuff I sent you last Friday?

This material will never crack, because even when fully cured, it retains a minor deegree of elasticity, while still having a huge bonding force, to let your components stay put.
