Hi!
Was wondering if anyone could help or has had any experience with these issues:

My ss has a good running motor with a dellorto kit instead of the webber.

the bike runs and revs fine with good power throughout rev range but engine will die completely after a couple of minutes at sustained 4k and above riding.

i spent alot of time trouble shooting and ive ended up with the tank possibly being the culprit.

When i had the tank off i found that the return and breather pipes are partially blocked. i think it might be the tank sealer the previous owner installed and possible corrosion. i can blow air through the pipes but there is varying resistance.

will this affect the fuel pumps/systems ability to fill the float bowls to the point it's starving the carbs?

can i cut out all the pipes inside the tank and replace them with rubber lines to improve flow?



Thanks.

To check the breather try riding it with the cap open to see if it still cuts out, not with a full tank obviously.
I sure you could replace the internal pipes with rubber but be aware that you will need to use rubber hose that is suitable for immersion in petrol which may not be easy to find and this may be more of a problem with today's high ethanol fuels.

Have a look at the topic viewtopic.php?t=6277

It will save you a little bit of time!

And welcome to the site of knowledge!

Does the modification of the Carby include a fuel pump?

Cheers.

Nick.
