First thing is do an oil change. Reason being is because the clutch uses the engine oil for lubrication. If you have old oil that has broken down it can cause problems. I run synthetic, Mobil 1 20w50. Give that a try first. If that doesn't work, you will have to take it into the shop and have the clutch plates looked at.
It takes about 7 seconds to reach 100 mph in 4 gear. You can not reach 100 mph on a Yamaha R1 in 1st gear. It's impossible.
When ever you attach a gear with less teeth to a gear with more teeth, thus increasing your gear ratio and the speed in which the gear with less teeth rotate, the amount of torque in your gear combination decreases. This can also be expressed as a ratio, which happens to be the inverse of a gear ratio, meaning if your gear ratio was lets say... 1:5, the ratio for the amount of torque is 5:1, meaning you receive five times less the amount of torque, to increase your speed five times as fast.
A tulip gear: is a gear that transfers from the c.v axle to the front differential drive gears, the tulip gear will have 2 retaining clips on each side to keep it in place.
Your top gear or last gear you shift to. Depending on what make and model of your bike, either 4th or 5th on motocross bikes and for woods bikes it would be 5th or 6th.
You can purchase transcription gear online at the official Transcription Gear website. You can also purchase them from personal sellers online at websites such as Craigslist and eBay.
Yamaha
sounds like the clutch is slipping to me
how gear are shifted in Yamaha FZ byk
turn ignition system and fuel system on then put in 2nd gear and push
lighter oilin my 2005 Yamaha xvs 1100 i use penrite 5w 40 because it helps with the gear change .is a lot smoother because clutch plates don't seem to stick as much.give it a go.
Some can be started in this gear, yes.
Your Yamaha Bruin may not shift out of low gear because something may be wrong with the gear box, so you should have it checked.
Plenty.
most likely you can find it in the motorcycle store
Your motorcycle might idle fine and bog out when in gear because of a problem with the carburetor or the bowl. If either area is dirty, it will often bog the bike when in gear.
1500cc of gear oil 75w or 80w
Yamaha Viraho 750 holds cca 2 dcl of gear oil. I think it will be about the same.
