Someone dropped my motorcycle while it was parked in the street Apparently they wanted to take a picture on it and managed to drop it Since then I had a variety of problems some which are probably not related to it being dropped The biggest problem that I have noticed is that my bike a 2009 R6 does not accelerate how it use to after 3rd gear Instead of taking off when hitting the throttle it just makes a lot of noise and accelerates very slowly The noise it makes sounds just like as if it were accelerating rapidly but the bike is actually slowly gaining speed This happens in all gears but most notibly 3rd In addition to that I have been losing fuel very quickly I would fill the tank in the morning and after riding 30-40 miles the light will be back on I have not noticed any spills whasover The last problem is the rattling noise that it now makes which happened immediately after the bike was dropped Michael

SOURCE: Engine Making Noise when accelerating

Could be carbon build-up on the pistons, causing erratic flame travel in the combustion chamber... 'pinging'...... Decarbon the engine and use a high grade fuel for a few tanks.... also an octane booster can help

SOURCE: no acceleration,audi 1.8t,runs like no boost

have you tried cleaning out the throttle body as i had a similar problem and this worked

SOURCE: High pitched electronic/dentist drill sound when accelerating.

Probably the front differential, your probably hearing the famous differential gear whine. Change the oil, put Lucas for gears in it. You can get a hand operated oil pump to **** it out through the dip stick if it has one. Then fill it with the recommended amount.

SOURCE: Loss of acceleration. Transmission? Clutch? Cable?

Try replacing the clutch cable first, these cars came with a simple clutch cable that is cheap & easy to replace. the end that hooks to the clutch pedal is plastic & can wear out. the later VW golfs came with an expensive automatically adjusting clutch cable. these can be installed in older VW's.

the old cables had to be manually adjusted like a motorcycle clutch cable. check a vw service manual. there needs to be a bit of slack on the lever that pushes the clutch disk.
if it is too tight the clutch may not engage fully & you will cook the clutch & flyweel.

Also check the shift linkages, there are many plastic bushings in the system that wear out
and can make the shifting sloppy. these are cheap and easy to replace.

Personally I have not had any real problems with the 5 speed transmissions in VW's.
although I have hear of a variety of problems with latter VW's trashing the transmissions. The automatics are another story.
The 020 transmissions were built to handle the 75hp/ 1800lb Schricco. putting them in a
Golf GTI with 150hp, or a 3000lb jetta 3 caused lots of problems.

ps: I would pick up a cheap used 5 speed from a junkyard, preferably out of a Rabbit, not
a golf or Jetta. take it to a machine shop to check for the usuall problems to see if it ok
before installing it. If that fixes the problem get your money back from the people that sold you the rebuilt transmission.

if the truck feels like,
the more gas you give it the slower it goes,
you might want to check for a converter plugging up.
