Hi,

My Skorpion Sport is jumping out of 5th gear. it happens at higher speeds (+120 km/h) and it goes directly in 4th, causing the engine to go into the rev. limiter for a second (untill I've pulled the clutch). At begin it did only at +140 km/h but lately it is happening more and at lower speeds. So it is getting worse.

I already have a ∅8mm shift lever linkage instead of the original ∅5mm. At first I thought the original was the problem due it's flexibility, but it isn't.

Is there anything I should check first before pulling the gearbox apart?

check the magnet(if you have one )on your sump plug,,if you see any metal bits then i would suggest the selector has worn ,,this is not a rule of thumb but an indication..if your unsure drain your oil with an old magnet in the bowl, swerle it round and then look see ,

Ok thanks! I'll take a look at the oil.

Just curious, which part is the selector? Maybe number 11 in the next picture? Or 15?

I'm sure number 6 is 5th gear selector. It's got to be worth checking for signs of wear on the end of the selector drum before you split the crank cases. Good luck!
I discoverd this 2nd gear problem on my spare motor: Please note (Radiograf) I to have discovered the rule of turds ((without photo edit))
P.S. PLEASE DO NOT ABUSE YOUR MOTORCYCLE BY TRYING TO WHEELIE THROUGH THE BOX WITHOUT USING YOUR CLUTCH, it's not big and it's not clever! OUCH!

I recently bought a '96 Skorpion Sport. It makes very unpleasant noises and vibrations in 3rd gear but still it keeps going. Anyone else have this problem? A mechanic friend rode it and said he thought it was due to the hardening wearing off the gears. Would be grateful for any help.
