Which sealant for left-side engine cover?

I wonder which sealant is best for assembling the left-side engine cover.

Actually I use Arexons Motorblack, but I read on some forums that a gel sealant is much better than a sylicon one, because "It goes on a bit tacky and will hold a gasket in place extremely well, for assembly. It allows separation with ease and if kept clean, it will allow reassembly without reapplication and you can use the vehicle immediately". The author of this commet suggest to use "HYLOMAR®* HPF Gasket Dressing and Flange Sealant".

So, what do you think about?
Are there any products by Loctite or Arexons similar to Hylomar?

I would say the proper paper gasket.
I usually only use paper gaskets after applying some oil to them. Never had any problems. In case there is no paper gasket I use Hylomar. Works great, but it depends on application.

In this case, it seems to me that Ducati no longer use/produce paper gaskets for lesft side cover... so do you suggest Hylomar?

that these gaskets don`t exist anymore is totally new to me.
I`ll check on tuesday as I will be at my dealer again.

Ducati uses 3-Bond on the engine cases and cover instead of gaskets now. Yamaha calls the same product Yama-Bond. In the states we can get the gasket from:

I heard just some dyas ago from my 888 friend, that Ducati DONT have(use) anymore paper gaskets and they use some red silicon seal, etc, what You can but quite cheaply from Ducati dealer. I need also that very soon, so if i remember, ill post results, what i can get

ps. if use thinner gasket, remember to "reshim" at least another pick-up! (in 907IE) Pick ups are very important to be in right dimensions. In 907 and 888 it must be 0,75-0,8mm

I've been using Hylomar on my 750 GT rebuild and it's been working great.

I like it a lot better than Yamabond.

Some days ago, a ducati mechanical suggested me to use a red silicon seal, or as well, the black one, well known for the fiat fire engines
Have a nice ride, Nicola

3 bond is good but very messy and can get things clogged up and do damage. If a papergasket was stock on the bike it is best to use that again or if not available make one yourself. Takes more time to make a gasket but when clean up time comes you will be happier with the paper one.
