Welcome to the Forum & posting Neoajax - sorry it's gotta be with a problem! And that it's a bit hard to tell what might be wrong with your Spyder from the little info you've given us, but people have been looking in to see if they can help.
So in an attempt to get the ideas/discussion started, can you give us a bit more info?? :dontknow: .
- Is your RSS a manual SM5 or is it an SE5?
- Have you actually tried to get reverse & can't, or is that just a supposition?
- What about running it - does the Spyder's engine actually start & run?
- If it does run, can you get it into any gear & get it moving?
- If it does get moving, can you run it up & down thru the gears while it's moving; and
- Can you count how many gears you've actually got if it's moving & you can select some gears?
Beyond those questions, another thought - what about the oil level - these Spyders have a Dry Sump system & a Wet Clutch, and the Engine & Gearbox/Clutch share the oil, so it's pretty important that you've got the right amount of oil in the reservoir - there is no real 'sump', but once you've stopped the engine, oil
WILL very quickly start to drain out of the reservoir & back into the engine/trans, so you can't really/reliably check the oil level unless you check it within 2 mins of riding it for at least a minimum of 10 mins on the road, changing up & down thru the gears;
or you've run the engine for long enough to get the oil up to its proper operating temperature - ie, run it for something
MORE than 10 mins AND at least 2 fan activation cycles! Checking the oil level more than 2 mins after shutting it down after a ride; using the wrong technique; &/or checking it cold will
ALMOST ALWAYS give you a Low reading, and adding oil to a cold Spyder engine/gearbox cos you think the oil level is low when you haven't run it
is VERY likely to result in over-filling it.... and either Low oil levels or High oil levels can cause gear selection & change issues, or possibly even worse things!! :gaah:
Over to you... :thumbup:
