Certainly is good advice.
It made some difference to mine when the master had been round it.

I agree re: taking it to Griff, and have already provisionally booked a suspension setup session in the new year... but I would also like to know how to set this up (albeit without expensive equipment such as CO meters).

I do have a home-made manometer using ATF and a piece of 2x4 and metres of rubber tuning... worked well on my IL4 so thought I'd use it on the Falco...

...although it appears the best advice is to use the two vacuum ports on the RHS of the TBs and not the smaller tubes on the clutch side... the problem is I can only see one vacuum port on the RHS that is used for the clutch.

Yeah you don't want to play with the trim pots without a CO meter .... I'm still looking for one at the right price ....

I expect it will work fine.

errr isn't the clutch on the RHS ??

Also, as you have one of the early Falcos, you may have a set of the early throttle bodies.
In the picture below the early ones are shown on the left and the later ones on the right.

The early ones are missing a vacuum port and you need special adapters that fit underneath the throttle bodies to balance the TBs with vacuum gauges or a manometer.
Take a look in the workshop manual - the adapters and how to use them is shown in there

Yeah sorry, I meant the clutch slave cylinder side is the LHS

Yep... I have the earlier ones... no-wonder I couldnt find the second vacuum port

I'll have a look at the manual :)

EDIT: what a pita re: special adapter for balancing tb's...

Why oh why would Aprilia have omitted the vacuum point on the early models!

If you have to take them off then it should be simple enough to drill and tap in the blank for a spigot to emulate the later models, just a thought.

I've looked in to this .... the old set pictured is a set I picked up from ebay - not realising they were the old style.
I was thinking of getting them bored to 54mm but didn't.

Anyway I asked a company that bores them about adding the vacuum point and they said it can be done but is very expensive as it's very difficult to obtain the right bits to fit in the hole - the bent pipe thingy.

Rick - if you want a pair of the later TBs, I could be persuaded to part with the pair pictured.

Is the only difference the blocked vacuum port?

D-Rider · #53 Post by **D-Rider** » Mon Dec 06, 2010 10:21 pm

Not sure - it's the only difference I know of.
I do have a spare set of both types so if I can find the time I'll have a look - but might not be soon.

ok yeah whenever... i'll probably look at balancing using the smaller tubes... although i'll also probably just see griff in the new year when he sets up my suspension :)

not done much since last bit of work, although I have ended up removing the sealant on the carbon plate and ended up adding some foam to the bottom of the pipercross filter instead. Its not a much better fit and i dont have any silcone on my loverly carbon!

i've just popped out to buy some small jubilee clips to replace those stupid aprilia clips... and 2x3m of ventilation ducting to remove the exhaust fumes from the garage when starting the bike!

Next bit of work is realistically going to be Sunday when SWMBO has given me a pass for the entire day! Work to do includes oil and engine filter, coolant change, drain hydraulics (front brake and clutch only) and remove forks for new seals and oil.

PITA!

Put the Rene kit back on tonight, avec snorkel (older style on mine

) but the back of the snorkel must be catching a bit on the throttle mechanism on the TB meaning that the throttle sticks a bit when let go.

As soon as wifey returns from Zumba (whatever the hell that it lol) I'm gonna have another go... damn frustrating I can tell ya!

EDIT - forgot to mention - the foam on the underside of the tank is still there, but I've read somewhere that this should ideally be removed when fitting either the rene or evo airkits... I understand why for the evo (the filter isn't over the velocity stacks so foam could age, flake off and end up in the combustion chamber) but why is it recommended to be removed for the rene?

Snorkel?

This thread is useless without pics..

rick · #57 Post by **rick** » Thu Dec 09, 2010 9:13 pm

This is the snorkel I am referring to... the earlier one on the left (andy's pic i think):

I'm popping to garage later to have another go... it fitted before without causing the throttle to catch on it... its just a case of finding a sweet spot with it I'd imagine!

Snorkel with a rene kit has me baffled?

Rene filter plate (carbon fibre) with Pipercross filter held on by two dzus fasteners.

No snorkel involved?

rick · #59 Post by **rick** » Thu Dec 09, 2010 9:18 pm

Yup... snorkel fits to bottom of rene plate...

#60 Post by **Kwackerz** » Thu Dec 09, 2010 9:22 pm

Ah see what you mean, front inlet ..

yeah with you now.

Foam removal with the rene kit would be to promote ease of airflow to the top of the filter.

S'been a while but im sure that is why the underside of the tank would be 'cleaned' in such a way
