Fireblade Aries Problem
Took the Aries Locoblade out this afternoon, but it would only rev up to 8200 then it would just sit there like it was on a limiter 
I've been having a few issues with gel forming in the fuel, so first thoughts was to replace the in line filter which I did but this didnot
help
I've now taken the carbs off and emptied them of fuel just incase they were full of rubbish, but they seemed clean.
While taking the carbs off found 1 of the clips holding the carbs to rubber pipe between engine and carbs had a nut missing, so I'll replace
that tomorrow and re fit the carbs to see if that was causing the problem (air being sucked in).
Could it be anything else? like the cold air temperatures?
Any advise greatly received
Cheers,
IainL

Carbs freezing up? It's pretty nippy out there. Try letting it sit for a while until the under-bonnet temperatures are nice and toasty and then
rev it and see.

The gel you refer to sounds odd, has anyone used silicon to seal in anything on the fuel tank, sender etc. If so the fuel attacks it and turns into a
telly which floats about in the tank and gets pulled against the outlet restricting the flow and giving exactly your symptoms. It happened to me on my
F2 sidecar at the TT and couldn't get the outfit to rev past 8000 rpm. In general the blade carbs don't suffer icing problems so I
don't think it will be that.

Oh I forgot to add if there is silicon in the tank as it is pulled through it coats the filter element and stops it passing fuel

Just to add to Andy's (always amazing) suggestion is to check the float bowls for crud, even just a coating of discoloration can be enough to
start gumming stuff up, then you also need to check the float bowl needles. They are a small (~23mm??) long turned aluminium stem with a rubber cone
shape point on the seated end. Check this rubber for any particles or discoloration and also check the seats where they prev were situated. Give
everything a clean (think I used acetone) and refit...
A relatively simple job, just make sure you've got a clean level working environment so nothing rolls to the floor!

Hello!
I read somewhere here (I believe) before that when not using the original airbox, the carbs needed to be "re-jetted". The idea was
something like if not using the original airbox, the airflow would be less so the needles had to be enlarged to get more fuel through (or something
vaguely like this).
Could it be something along this line?
Good luck finding the issue and solving it!

Just incase anyone want's to know the outcome.
I've at long last managed to get a couple of dry hours out on the road and after removing the old Pipercross Filter Socks everything seems to be
fine now, so I'll be forking out for some replacement socks. 
Well it was going fine until 1 of the magnets for the speedo pickup deceided to part company from the prop, but luck was on my side this time just
found the magnet still attached to the prop but a bit further away from where it was glued.
Thanks for all the suggestions.
Cheers,
Iain

I wasn't aware that you were using Socks as method of Carb Filtration.
In my (Humble) opinion, Filter Socks are about the worst way of filtering for a set of carbs... They sap power too...
What you want to get is either an airbox (this will help with noise, and doesn't have to be a posh polished Ali one, it can be the OEM one if it
would fit?).
Or you could get a Panel filter or, Sausage Filter.
There are a few simple guidelines to stick too with regard to choosing a filter though.
These are more like hints rather than strict rules as you can't always adhere to them. For eg, you really want the height of the inside of the
filter to at least equal the width of the Carb trumpet off the trumpet itself. One and half times would be even better, but it's just what you
can get away with under your bonnet etc...
