It seems that often, bikes offered for sale on EBay and elsewhere have non-standard (from Greeves) carb setups. MY 24TCS Scottish is currently fitted with an S25/6 carb (as is correct for a TFS!) and a 'standard' air filter (with the sliding choke on the filter body) which is what was fitted when I bought it. Also, the rod operated choke (strangler) has been removed and the hole for the rod blanked off with an appropriate sized screw.
This setup seems to work well (if it aint broke etc...!) and gives easy 2nd. kick starting with the choke slide closed and a good tickle (flooding.) However, as I intend to gradually put the bike back to standard spec, but with 'sensible' mods so the bike can be 'used' as intended, I've sourced parts accordingly for when I decide to rebuild the bike. These include an '1800' air cleaner to replace the 'standard' item currently fitted (see pics below.) I was also going to refit the rod 'strangler' assembly, but was given the following advice by Villiers Services.
The rod/strangler has been known to drop down during off road use and obviously this will choke/kill the engine, sometimes when you least want it too...! For this reason many trials riders leave the rod and strangler assembly off and balnk the hole as mentioned previously, fit an '1800' air cleaner and just flood it when starting.
Also, I note that there are two possible specs (not counting the S25/1 with the choke cable arrangment) for a 32A carb;
S25/6 Choke bored to 1", with strangler, rod operation; 32A and Starmaker. (What I currently have, minus the strangler, and correct spec. for a TFS as already noted.)
S25/2 Standard carb body with strangler and rod operation; 32A and 37A.(The correct spec. carb for my TCS.)
I was wondering if the correct S25/2 carb might give slightly better torque being a smaller choke size, and if there is any point/advantage in trying to find one to replace what I already have?
Any thoughts from our experts on these points would be interesting to hear.
Thanks,
Brian.
