Suzuki gearbox problem gsf 1250

Could be a number of things, a worn or loose chain will make finding gears more difficult so check that the chain and sprockets are not excessively worn or loose. An overly stiff or floppy gear lever and linkage can cause problems selecting gears too. If it is neither of these however then it is most likely a bent selector fork in the gear box

Ive got a 93 suzuki gsx 1100.started gear lurchingwhule driving in every gear then stopped moving no matter what gear its in. what possibly happened and how do i fix it

Hi davy, remove the front sprocket cover, see if the sprocket nut has come loose or worse the driveshaft splines are worn. This would explain no drive in any gear. Other than this these engines and gearboxes were bullet proof, getting on a bit now though. Hope this helps...

2000 gsxr 750 gear shift problem

Hey Tom, .. OUCH.. sounds serious..FIRST - STOP "hot rodding" this bike. especially in the lower gears!! Now- the gears have "dogs" on the sides of the driven gears and on some of the wheel gears, and holes in the other wheel gears..(wheel gears are the non-drive gears - thats why there are 12 gears in a 6-speed transmission). This sounds like the dogs are on their last bit of "bite" (the dogs engage each other or the dogs insert themselves into the holes of a wheel gear).. once these dogs start to wear, they wear out faster and faster. ALL the transmission gears are "case hardened".. the outer .040" - .065" of the gear are "case hardened", the internal area is left softer(teeth too)..If they were HARD all the way through, they would be too brittle and shatter!! (I could tell you A LOT about more how this is accomplished and why - but just know this is the way it is!) Once the hardened area is worn down,, failure is imminent.(and much more expensive that repairing a NON-BLOWN-UP TRANSMISSION). The gears must be replaced as sets(usually the driven gear and wheel gear)..THEY MAY NOT BE EACH CALLED FIRST GEAR!!. THIS IS A JOB for a FACTORY TRAINED QUALIFIED PROFESSIONAL , - WITH EXPERIENCE!!! Or else you MIGHT have trouble in the future or spend money when you do not need to!! Sorry to tell you this... but it happens when your bike has been rode hard!! (its not uncommon!)

Hi just got a kymco stryker, the bloke said that it would make a clunkin sound in 2nd 3rd and 5th (sounds like the chain jumping) but on the way home , he said it was best to stay out of 5th,i did so...

I doubt that the chain was jumping the sprocket. A chain that loose would wrap up around the front sprocket and lock up the engine and/or bust up the center case. It sounds like the bike has some serious transmission problems. The bike probably has bent shift forks and a few busted gear teeth and possibly broken dogs on a slider gear. The bloke ripped you off. The wheel being out of line is not a factor. Please rate my answer. Thanks.

While riding, the 4th and 5th gears do not engage promptly when you clutch and shift the gear. It sort of goes into neutral as one disengages the clutch and accelerate and then falls in place (ie 4th or...

This behavior is the symptom that your clutch plates are getting worn out. Since power is transmitted from the cam shaft to the front sprocket (smaller dia) is better at lower gears but once the rpm increases the clutch plates do not catch up with the cams rotation, hence slipping at higher gears & in between 4th & 5th gears the pulling power of the engine seems to go to neutral before engaging again. Check your clutch plates as well as the sprocket-chain- rear sprocket for wearing out of the gear teeth & replace if required. You will get back full power & acceleration as when the bike was new.............sodeep

Loud clunking under acceleration

I would expect no damage to the sprockets. They are hardened. I must have replaced 2-3 hundred on Jeeps with Quadra-trac; never replaced a sprocket.

Noisy 5th gear

but no there was definitely a loud whirring noise in 5th gear sort of like a very noisy bearing. The bike still ran in 5th but it was definately becomming increasingly noisy. When I changed down to 4th the noise went away even if I slowed to the rev range I had been cruising in 5th. Same story with the other gears, but the noise returned with a vengence in 5th. Needless to say I rode the rest of the way home in avoiding 5th. Any ideas? I suppose I'm looking at a gearbox strip? Could the noise be anything else? ,Had a similar issue with my 1000S, only 5th gear was noisy - a sound like a dry bearing -other gears were silent. Bike had done 70,000kms and serviced correctly. Had Barry from IME check it out. Turned out to be both 5th gears needed replacing - looked like the case hardening on the gear faces was eroding and pitting. New gears went in and the box properly shimmed and happy to say 6000 kms later all still silent in the gearbox department. Plus the added benefit of slicker gear changes.,,,
