    Posted: 10 Mar 2018 at 17:00
So, this morning the throttle ensemble was substituted for the "Lego" one, and everything seems just fine (boy, the first start of the year of a Guzzi's engine always reminds me of Christmas Morning when I was very little...; I have a nasty headache today but I want to ride tomorrow without fail...). 

We also changed the rear tyre and, to my surprise, the "tubeless" tyre actually had.... an inner tube. The mobile mechanic (this is Mark Vallance, the same one of last year, and he was very good again; I needed to use a mobile mechanic because I can only have the bike worked on on a Saturday and the bike obviously did not move due to lack of... throttle cables) explained to me that the wheel has a slightly different form on the inside of the wheel, such that it forces the use of an inner tube even if a tyre with "tubeless" written on it is mounted on the wheel.

I try not to obsess about these things, but boy I am now here reflecting that I have been riding with inner tubes when I thought I was riding tubeless all the time. 

So I am now thinking whether any of you has decided to switch a Mid-Eighties Guzzi to wheels suitable for tubeless tyres that are, ideally, reasonably priced (no super-fancy, space-age, brag-at-the-pub material), good to look at and, again ideally, not requiring new brake discs (albeit for this one could actually think about an upgrade if, again, reasonable to do and not requiring any DVLA hassle). 

Any experiences?   

Thanks

Omobono

P.s. I really can't avoid thinking of that engine as it started....

Just run with tubes in. That's what the wheels are designed for.

On the 1000SP, a tubeless tyre with a tube inserted is the norm. Essentially, that's not a tubeless rim.

Swapping the wheels, to a spec per your description would neither be straightforward, nor cheap.

Stop messing about. You've got the paint done. You've got the throttle and switches sorted. Ride it!

The 1990 1000 SP III had tubeless rims.
However, I have no idea if they would fit the earlier model.
 
Have to admit, tubeless is far easier to deal with when a puncture happens.

Thanks, Barry! 
Actually, I am afraid I will never stop messing about with this bike! Wink
What i will do is to pick sensible improvements every year, once this and once that, in order to make the bike more and more like I want it. 
But yeah, I will ride it too! Smile

All the older bikes have to run tubes in most modern tyres have tubeless written on them, as has been said run with it they work ...to find tubeless rims is difficult and expensive if it was easy many would swap rims .....as far as I know the tubeless are wider so it therefore may need swing arm etc it will then upset the handling .....as is often said oem works best especially on older Guzzis ....

Surprising how often this topic has come up in the last year or so - what they said, the cast wheels fitted to 1000 SP and other models are not, and never were, tubeless compatible. This was confirmed to me by my local bike shop who refused to put tubeless on (that is to say, without inner tubes included), and explained why. Also it could be a potential safety issue as regards insurance.
