Default HELP!! I think I broke my 06 Katana!!

If anyone can help me I'd appreciate the suggestions.

I just bought an 06 Katana 600 a month ago. I was eager to get the bike so they didn't perform the usual dealer maintanence on the bike, (Oil, Gas, so and so) I'll admit I spent a day or so in a wheelie frenzy, I was excited to get a katana up, with the powerband and the clutch. But Then the other day I was riding and I shifted up and heard a grind/click sound and then ever since then the bike has ran like it's in a gear or two lower than it really is. The RPM's are the same, but the engine runs like 5-8000 rpms higher. When I'm in 6th gear doing 50moh it sounds and feels like I'm in 3rd gear doing 70mph. I don't seem to have any torque or power now, it'll get up and go, but I think I might have messed the clutch up during my day of wheelies. Also when I'm riding with the gas on in 6th gear and let if completly off, the bike Jerks to a slow speed in like 5 or so seconds. Also I talked with a friend of mine and he suggested to change the oil, when I did, it was two quarts low and Black as Coal!!! Would this have damaged anything internallly???Can someone please tell me what I did to my new bike!! Thanks for anyones comments. Write me if you need anymore info~~Kalix

Oops, live and learn. Since you relayed that the bike was two quarts low (it only holds 3 quarts, right?) it sounds like you waisted a manshaft or layshaft bearing in the transmission. I'm sorry to say you most likely caused major damage to the motor/transmission. Also, the gears have plain bearings in them also, that might have gotten gauled up and sticky.

As a last resort I'd get some STP & Slick 50, run it through the motor (the clutch will have to be removed and cleaned up in acetone after that to get all the slippery stuff off it) and see if it brings any of the bearings back to life. I did that with a VW Beetle transaxle once, after running it dry behind a 120 hp motor, and it worked for about 5 years before it finally blew up.

Sorry buddy, but if that doesn't work, you're going to have to split the cases on that motor to get it going again.

Good luck. I've got a '76 XT500 for sale that runs (kinda).

OH yeah..I refigured the measurement of the oil..it turned out to only be about a quart and a few oz's low....would that still cause all the major damage that you were talking about? If not...then what might it be. and what is the cost for something like that to be fixed? Thanks for all your help buddy!!!

P.S. the bike manual says it holds 3.7 quarts of oil with the filter.

You don't know if the guy you bought it from abused the crap out of it before you started abusing the crap out of it. If the oil light wasn't on then you might not have fried the bearings. Try cuddy's fix but be careful with the slick50 which tends to plug the oil galleries. If using it frees the engine up I'd change the oil right away before it causes even more oil starvation.

HINT: Sportbike trannies are designed for light weight not for heavy clutch dumping durability. If you want to pull wheelies then get a DP bike or a Speed Triple or something designed for stoutness not track times. Clutch dumps are about the worst thing you can do to modern sportbikes with their often fragile trannies.

That would be a good idea, kalix. Motorcycles take some maturity.

The other possibility is that you fried the clutch discs.

That would make shifting difficult; it may cause slippage, so the engine is turning faster than normal for a given wheel speed, and it would certainly crap up the oil.

I think I'm with Pushrod, that would explain most of your symptoms. You should be able to test that the same way you would a car clutch, try starting off in a higher gear and see whether it slips. It would not explain the rapid slowing when you get off the gas, but I'd try routine maintenance before breaking into the engine (check brake pads, fluids, bleed hydraulics, check valves if necessary, etc.). I'm with Seru too, though I'm not sure that a Katana really qualifies as a sport bike, but it's not a dp or the like.
