Title: 2001 Varadero Carb Questions
Post by: GDP_Varadero on September 22, 2019, 14:32:20
Hi All,

Seeking some advice regarding the 2001 Varadero Carbs and whats the norm and when I should be concerned,

The bike has got about 100K Km's on the clock, so I cannot expect everything to be perfect, so I've stripped the carbs to give them a clean and noticed the throttle flap shafts are leaking where they go through the Carb body, I noticed this as there was a build up oil+dust around both carbs where the shafts exit the body,

I can feel that there is NO play in the shafts surprisingly for the age and mileage, BUT the felt washers seemed a little tired,

Whats the next best practice here?

Whats brought me to this point was the bike runs very rich due to needing to use the WHOLE choke in order to keep it running - climate 24 deg C + Until Warm, then idles without Choke.
Back firing on de-acceleration
Previous owner removed the exhaust Baffles

I've downloaded the Owners Manual for the bike, but doesn't say much about carb servicing except float heights,

Any insight would be greatly appreciated.

Additionally - Why would a Carb bike have TPS? Unless only some models have this "option"

Replace felt pads with new ones - not because of mileage but age.

Some oil in the filter chamber - this is normal.

Carburetor adjustment is possible, but it is more complicated - a detailed description in the service book - but to do this you need to have "somewhat" experience and a special screwdriver, a container for fuel supply and an accurate tachometer - or ear music :)


I think that TPS (since 1999) is only used to correct the ignition timing

Right TPS explanation makes sense,

Regarding the Carb adjustment - I'm only accounting for the more "Free Flowing" exhaust,

I noticed that someone has previously been into these Carbs though - the Bowl screws have seen some action,

In addition to adjusting the pilot screw 1/2 turns out - I noticed that washer under the needle was missing - which I added one myself,

Turns out those Felt washer are near IMPOSSIBLE to find here in Cape Town, South Africa - so I'll begin by greasing mine and taking it from there,

Thanks

Can any explain to me why my back cylinder plug is clean/washed - These are brand new - probably 1 hour of carb pilot screw adjustment and sync'ing

My issue is the back cylinder is intermittent during idle,

Both pictures - plug left = front | plug right = Back
