Aprilia

I bought a climber 280 cheap for some fun and before I fire it up I thought I would change the oil. I found a woodruff key stuck to the magnetic sump plug which is a worry. So maybe that's why it was laid up and cheap ? I see from page 14 of the manual attached there is a woodruff key each side of the crank. In the picture the clutch/carb is nearest. The key the other side must hold the flywheel though its not shown, and I guess this is the dry side, so if they was in the oil it must be the clutch side ? Any thoughts. How do I get the pesky clutch main nut off - is there a trick, maybe jamming the chain ? thanks 242ccet282ccTLAprilia1994.pdf

Hi all, I was out with the Climber a week ago and it ran fine for an hour but then when it was on tick over just stoped and didn´t start again. Back home I have been tracing the problem and have tried or rather changed the carb, plug, plug cap, kill switch, and the black box under the tank. I have now found out that when the plug is out and its turned over there is no spark the most of the time unless you turn the engine over a lot faster then the spark apears again. It´s not possible to kick it over this fast with the plug in and it just fires up very very ocaisionaly for a couple of beats now and again. I´m thinking that it´s in the stator plate…

So, I asked for a forum and here it is! lots of thanks!

just purchased a Can Am (Armstrong) CMT310 with the 323cc Hiro engine. I understand that Hiro was purchased by Aprilia, is there still parts available for these engines? Or for Armstrongs? Rick

I've acquired an Aprilia Climber. It's a 280, a 1993 model. Tommy Ahvala won the world title in 1992. So this is the replica, celebrating the Italian manufacturer's world championship victory. I fitted a Paioli RSD fork while waiting for the original Foral to be restored. It looks really nice. I spent a lot of time on the Foral fork. Bertrand Quartier had warned me about the rather poor quality of this component. Indeed, it's not great. Furthermore, a previous disassembly by someone less experienced had damaged the hydraulic system. I repaired it to get it working again. The fork was binding badly. The friction bushi…

I was just wondering how you would change the engines oil in an Aprilia 280 i cant seem to see how to do so and was wondering whether some one could give me some advise? Thanks Henry

hello all I'm looking at improving my fork behaviour again. Last year I replaced seals and oil , put in 260 cc of 20wt as I saw recommended on this board. It was way too harsh , I couldn't ease a wheelie down without hand shock. I switched to ATF which is 10 wt ( ? ) better but still harsh. I have since seen a recommendation of 10-20 wt in the rebound fork and 5 wt in the compression side. This sounds like a good idea but I'm not sure which is which. Is the fork with the adjuster for rebound? Also there is 2 allen screws on the top of the left fork , the one clicks so I assumed it is for adjusting rebound damping, clock wise ( ? )for more damping ( less spring back ) .…

hi peeps just got an aprilia 320 and wanted to change the gearbox oil, but looks as if there are 2 drain plugs on the bottom of the crankcase, any idea which one it is

Hi, I'm new to trials riding and have just bought an Aprilia Climber 280 1994. I'm not sure if this was a great move because I can't find an owners manual for it. Can anyone advise me on where I can source one or give me advice on oil capacities, grades and service information i.e. plug gaps etc... Any info would be gratefully received! Many thanks

how much gear oil is needed and what grade for a 92 climber 280? i have a funny grinding noise from the engine as if the kickstart is being engaged when running. starts and rides perfect so dont think its anything major. was in a bit of a sorry state when i got it. so possibly may just need an oil change. now running it at 50:1 as previous owner told me 70:1 so decided to play on the safe side. any help including a manual would be hugely appreciated. thanks in advance guys

I purchased a '92(?) Aprilia Climber 280 (purple tank and yellow fenders) a while back and found out that I need to replace the piston, rings, O-rings, wrist pin bearing and some other parts. I haven't been able to find much. Mike at the Tryals Shop in NY was very helpful but even he gave up trying to find pistons. Any help would be greatly appreciated. Otherwise, it's going to have to be sold as a parts bike.

Hi , whats the spares situation like on the 300TX for things like rear mudguards seat pads etc ? I presume Italy would be the best place to look or does anybody know better , thanks

Hi all, I have aquired a 280 Climber which is now running but quite unstable at tick over and just above. I have found that the PHBH26CS carb which is the air screw version (not the petrol adjustment screw type) seems to be missing one of the jets. The Pilot jet is I think made up of 2 jets one is deep down and a sort of atomizing jet or idle imulsion tube as its´s listed (which is marked with 68) and there should be an idle jet "deep" sitting in front of this but it´s missing. Can anyone help with the size needed ?

Hi, I'm looking for the air filter manifold for Aprilia TXR 312, I can't find anything for sale, do you know where to find it? It would also be useful to have a spare parts catalog or exploded views, do you know where to download it? Thanks

My 93 Climber 280 kicks back bad. I thought I was going to break the Kickstarter or my foot. I ended up bruising the bottom of my foot in our last vintage trials. I was hoping it was just a sheared flywheel key. I took it apart felt like the main bearing was loose. Took some effort but I managed to get the flywheel off. Main bearing was tight. Someone put locktite on the crank/flywheel. I cleaned that off. I should have lapped it but was in a hurry. Put it back together. It's tight now. I checked the stator and all screws were tight. Didn't look like it had moved. I put it back together and it's still doing the kick back. I tried both feet, tried when cold, when warm and …

I’m working on a 1993 Climber that has a tubeless rear wheel. The tire I received with the bike is tube type. Can I use this tire with tube? Would probably have to use a rim lock. Or should I buy a tubeless tire and valve stem or tube? Thanks

Hi any info on the 300 twinshock how do they compare to a 240/300 fantic and are the engines the same as the swm thanks.

Hi peeps! Just bought a climber 280 today and been trawling the net for info which landed me here. I've read the posts before and yes mine does have leaking fork seals..oh joy as it seems to be a common issue with these bikes..I was rather interested in the 3 seal mod mentioned elsewere in the forum as a possible fix!! If anybody on here has any tech info on these bikes I'd be very grateful, any manuals or parts suppliers contact details..that kinda thing..to be honest i dont even know the oil pre mix ratio so was going to play safe with 30:1 as thats what i run the track RGV on I've seen 50:1 or 70:1 but what do you guys use? Thanks in advance for an…
