Looking for a 2 stroke expert in Dunedin

[Fast Eddie]

Stripped the Aprilia down quite a bit today. Was pleased to find a lot of race track design has made its way onto the road version, seat comes off without any bolts/nuts. fuel tank is plastic and just has one clip and then slides out. has a proper fuel tap that seals it proper etc etc.. everything comes off easy

There was a ridiculous amount of oil and grease all over the engine, especially around the exhaust port of the left cylinder and all over the exhaust manifold.. Needs further investigation. Infact there is disturbing amounts of oil and grease all over the place so in the process of degreasing now but its tough work! I'm just using spray can degreasers and rags.. shit work, think im just pushing it around/smearing it around. Also finding a million threaded screws and mounts and shit. Poor Aprilia its had some useless twats working on it in its life. Arg.. can't even list all the things that have been bodged on it. Its gonna keep me busy

Engine fired up and sounded good today, I left it to idle for a while to see what it would do, Started trying to check powervalve operation as per workshop manual but after a while it dropped its idle rpms and then died.. Hasn't restarted on both cylinders since sooo.. there is def some issues going on with it. It starts but only runs on one. Didn't get as far as plugs out, maybe do it later tonight before dark.

Hmm... oh well all fun and games!

Who knows where this mysterious grey wire is that is used to check the powervalve operation? I can't find it.. according to the workshop manual its supposed to be next to the battery just hanging around but couldn't see anything on mine

Seeing as it's an Italian bike the electrics are prob best left to Lucifer to sort.If it's anything like the RGV then the checkwire should be located along side the battery negative lead wire.There should be a female part of a bullet connecter on the end of the wire.

yip, should be the same as the RGV, it is supposed to be alongside the battery but I can't see it...

here are some photos, can you spot it? in the 3rd/4th/5th photos I show a wire i found (the photo with my finger in the way) that goes no where and its around where the bottom(right) cylinders exhaust valve is.. but I'm color blind, I don't think its grey.. and it looks insulated over the end of it so would have to strip that off to connect it/earth it to anything.. grr.

That slut is gagging for a raping bro.

MOAR PICZ!!!!!!!!

[Fast Eddie]

have found 2 more wires which lead to no where.. They wouldn't be there if they werent supposed to be hooked up to something but bike still runs without it hooked up so it just makes you wonder!!

these 2 come directly from the handlebar end of the loom and appear to come from the throttle side. But I have no idea where they should be attached.. I can't see another end around thats obvious.. One wire is the one with the plug on the end which im holding onto, the plug end is a bit munched up, and the other u can just see if u follow the wire im holding down, it is the little blue wire which has been cut and had tape over it.

fun fun fun, if only there was some sun.

IS THIS THE GREY WIRE TO CHECK EXHAUST VALVE OPERATION?

I'm color blind.. looks to be what I would consider grey haha.. but its on the wrong side of the bike according to the manual.. but thats not reall suprising since everything is wrong on this bike

[Fast Eddie]

here are the plugs, I didn't think they were too bad.. oil fouled but that cleaned off pretty quick. no coloring on the white/ceramic bits at all yet so either they are fairly new plugs... or somethings wrong haha

Plug on the left is from the top(left)cylinder and the one on the right is from the bottom cylinder. Top one seems to be getting a good load of oil on it.

I soaked them, cleaned them, gapped them, sprayed contact cleaner all over them and the caps and threw em back in for now. They should make a spark. will replace em later.

[Fast Eddie]

couple of bling shots haha..

gotta love the works racing dept tag and the gold Brembos all round



also who knows of a better degreaser that doesn't react with rubber? the one im using now turns any rubber bits a dirty brown color, i.e. my tyres and radiator hoses/any rubber bits. makes it look dirty even though its clean.

brand names,prices and where to buy thanks! I'm in Dunedin so don't tell me of a great little shop in Auckland..

[ducatilover]

That wire is grey

Looking good man, I want those Brembos!
As for random wires, who cares, my shitisaki had a few of them. The CDI unit has even got places for more wires...two I know are the speed restrictor and it has a hissy if you disconnect it (don't worry, it's not restricted, I'm far too smart)

I'm 4 fingers deep right now. She loves it..

need to buy all new stainless/zinc hardware and fastners though every little screw and nut and bolt is rusty and ugly. gonna have to rethread some shit too. Some real monkeys have owned this before me.

[Fast Eddie]

That wire is grey

Churr thought so, it looks like the wire im looking for some I'm gonna hook it up once I'm done cleaning the exhaust valves and see if they operate. more pics to come haha..

I also need to borrow a Battery charger and a compression tester with flexible hose (I have fixed type and its no good to me) If anyone in Dunedin would loan me these for a day that would be brilliant! Can buy ya a 6 pack of watery beer

[ducatilover]

Get a huge bag of cap head buggers, that's what I'll be doing. None of the old fashioned ugly bolts!

[Fast Eddie]

Battery charger and compression tester in Dunedin anyone..

gwaaarn... Wanna keep up the momentum

That'll be the one.

The most easiest way to check PowerValve actuation is to warm her up and then rev it up to over 8500 rpm and hit the kill switch (not the ignition key) this will leave the PV's in the fully open position.
Do your checks from there,she's a two stroke and only 4 stroke homo's care about midrange.

When you turn the ignition key off the PV's will automatically go back to the fully closed position.

I've only skimmed this, but 2 points: plugs once fouled often don't recover even if they spark outside the engine. You can swap em over & see if the cold pipe (not firing) swaps to the other pot.
2nd those PVs need checking every so often, - as in take them out & inspect. The rivet holding them together shags out & it can drop into the piston. Makes a ticking noise depending how bad, but gets worse quick. Tends to be a problem more on the upper cylinder, or rather a damaging one. RGVs, RG150s, RMXs all do it.

Anyways get onto RGV250.co.uk. There will be more info in a search there than anything here.
