SOURCE: Pops out of 1st gear under acceleration.

Hi Buddy
There is not an easy solution to your gearbox problem,it is general wear on the 'dogs' or 'shift drum'..The only other thing it could be is wear on the 'external shift mechanism'.
I,ve just rebuilt a 1996 vn1500 classic whitch had the same problem so if you need any advise or step by step photos please email me at ''

simply remove the sump plug which is in the form of a bolt in the bottom of the engine you may need to remove sump guard if you bike has one fitted once drained you may want to flush it with a good quality engine flush then just refill with the correct amount which is usually stated on the clutch casing near the filler cap hope thos helps

SOURCE: 2008 Z750 bad grinding noise in first gear

It is possible that the first gear shift fork in the transmission is bent causing the 'dog-clutch' between two gears to just barely mesh. With engine off, push the shift into first and clutch lever released. Rock the bike back and forth to see if the gearing seems to be jumping in and out. There may be a problem with the shift lever shaft mechanism not allowing a complete shift into first gear. Hope this helps!

Why is differential 90 weight gear oil leaking out by the bottom of foot shifter in that area you can see it leaking on ground and in starter the gear oil for a drive shaft bike not a water cooled bik

After riding the bike the oil warms and thins so finds it easier to find its easy out.
It sounds like you have a leaking seal that needs replacing.
Found out exactely which seal is leaking by wiping all oil off the bike and getting down and watching where it comes from it will start with a drip then go from there

Why is niety weight gear oil leaking out of my gear box on my 1982 gs suzukigl 1982 100

Is it from a gasket or is the cases cracked?
If the cases have a crack it will leak.
If the bike has sat for a preiod of time the gaskets had a tendency to dry up and shrink and harden - then when you start using the bike again theses areas leak oil

My 07 kikker 5150 110cc bike is leaking gear oil and make a funny noise ever since i rode it down a hill full throttle did I screw it up for good?

Where is it leaking from ? Shifter, chain gear shaft, case, case to cylinder ? Does the engine still run the same ? Is it under powered now ? Is the engine making any noises now that it didn't before the hill ? Is the engine lacking power now ? Other than an oil leak what makes you think you screwed it up for good ? Most engines/transmissions at some point will always leak oil. That doesn't mean they are screwed up. It normally means a seal or gasket is worn . They are designed to do that with time and wear.

My 2001 yz250 is leaking alot og gear oil when idoling out of a hose coming out the bottom of the bike then wen i shut it off it starts leaking coolent out of another line coming out the bottom of the bike...

The leaking coolant is a sure fire sign that you likely have a blown head gasket or your water pump is not pumping water any longer and the bike is overheating.

The leaking oil could be coming from your power valve vent - is it pitch black oil and is it coming from the front of the engine?

What color is the oil? Are you sure its gear oil? Is the gear oil milky and foamy? Is the gear oil level high or low? Is there water in the oil?

Sorry for all the questions - there are several things that could be happening here.

What are some common problems with the ktm 530 exc-r 2008

as with all bikes of this nature, check for runout in wheels, loose spokes, lighting working, suspension not leaking, brake discs for exsess wear, check coolant level , check engine oil for evedence of water, leaking water pump, radiator cap leaking past overflow pipe this could be pressure in system due to head gasket failure, fuel leaking, also check area around eng oil plug for evidence of repaire with cemical metal or similar, slightly noisy tappets is not uncommon,, normaly prety good bike, avoid bikes that smoke exsessive, check all gears are working correctly. dont jump out of gear ride in every gear and check for mechanical noise from gearbox, good gearbox normaly easy to select, doesnt jump out of gear, if u are looking at buying a bike of this nature they are fairly high maintenance, like to be cleaned , oiled and addjusted frequent oil changes, these are basic things i would check when buying a machine of this type, not nessasary a ktm, and these coments are not meant to harm your decision only help you chose the rite one.

My rm 80 1stand 2nd gear locks wheels

If your rear wheel is locked up in first and second gear with the engine running, this is not a good sign. Have you ever ran the bike without oil in the transmission? Every time I've seen this, the chain was thrown off the bike and it busted the cases. The oil leaked out of the cases and the transmission locks up. Generally, it locks in fifth gear but it could lock up in any or no gear.

Your problem sounds like something is wrong with the low gear-second gear "clutch gear". The clutch gear is gear that slides sideways on one of the transmission shafts to engage the proper gears. If the bike will roll when in neutral, these may be the only gears affected. If the bike will not roll when in neutral, your problem may be in countershaft. Either way, the transmission could be damaged.

Now, if you're talking about the rear wheel locking up if you try to push start the bike, this is because in low and second gear, there isn't enough mechanical advantage in the transmission to overcome the engine compression. Remember, you transferring torque through the transmission backwards when you try to push start the bike. Try starting the bike using third or fourth gear instead. Standing on the pegs and dropping onto the seat when you release the clutch helps.

Gear oir

i dont own a harley and never have, but have had honda, and triumphs, your gear oil could possibly be your engine oil as well, the engine oil has dual purpose,,,,, no there no such thing as a dumb question,,, thats how you learn, ring a harley dealer, as to talk to spare parts and tell them year model of your bike and ask them if it has a seperate gear oil from engine oil, if it has ask them where your filler cap is, it might be under seat or under tank. my radiator cap for my daytona is under front tank cowl panel,,, ask dealer to be sure on everything with your bike

Finished about a 300 mile ride was pulling into the garage and noticed that gear oil was pouring out the left side of the bike


Sounds like your gear box is wounded... actually, its possible excessive gear box oil is comming out the vent. Check the gearbox oil level before your next ride and check for leaks.

Cheers, Jay
