Try this: shift into the highest gear and release the derailleur cable at the derailleur. Pull it taut and retighten the pinch bolt. Give it a thorough washing and degreasing, too. A clean drivetrain is a happy drivetrain. Remember to use bike chain oil, not anything else, on the chain and ONLY on the chain.

How do I change my right shifter?


It depends on how mechanical of a person you are. In simplest terms we'd unscrew the old one and put in the new one. Calibrate and then ride. Without model number or any other specifics we can only give you a general response.

For my bike, I'd change gears to the smallest gear first. Then I'd locate the screw holding the whole thing in place along the underside... unscrew. Then unhook the shift cable from the shifter. Then unthread that cable through the bike frame until I get to the derailleur. Remove / loosen the screw that holds it in place. Put the new shifter in place. Hook the cable back in. Change shifter to position of the current gear and thread the cable back through the bike to the derailleur. Slip cable back into place and tighten. Calibrate and ride...

The chain feels and sounds like it's jumping gears or slipping on the rear sprockets. It does it in all gears. It is a diamondback wildwood large 20"


The rear derailleur needs adjusting, once to establish limits (so it can't go past high gear or low gear). Everything else is up to you fine-adjusting the shifter to make the bike run quietly. If you're careless about your gear changes, you'll get MOSTLY into one gear but not quite perfectly, so the bike is always trying to start shifting into another gear - that's the sound you hear, the sensation you feel. Fine-tune your shifter positions each time you shift - you'll find a "sweet spot" where the bike runs almost perfectly silently.

No, they can't readily do that at the factory, not with chain drives. There are just too many things that can affect gear changes, and things are in a slightly different position every time you remove & replace the rear wheel, or even loosen & retighten it. Unless you're ready to spend vast dollars on a foolproof shifter system, shifting cleanly is going to be your job and your job alone. It's one measure of your bike riding skill... and the better you get at that skill, the better you feel about it.

...and your bike will like you for it.

My clutch is slipping,my bike want even pull itself. Someone told me to change my slave cylinder first befor I tear into the clutch plates,so would the bike even go into gear if the slave cylinder is


clutch plates need replacing , I would replace the steels as well and also change the oil and filter as it will be polluted with clutch dust.
Would also help to flush clutch fluid as well.

Gears keep slipping


Have a trusted bike shop adjust the shifter cables. I'm told that all new bikes need to be re-tuned a month or 2 after purchase due to cable stretch.

All gears from 1 to 5 are slipping. each gear


does the clutch lever release "sharply" and snap back after engagement? then lean bike over drain about a quart of oil, take off access cover to clutch and check to see if you have any broken clutch springs. if thats looks o.k. you"ll probably need new clutch plates. a real quick check when you ride the bike smell the oil, does it smell burnt? if it does, the plates are probably no good.

Kick start wont return and feels like its slipping out of gear


Sounds like a broken kickstart mechanism or spring. Youll have to take it apart to find the damage

Above 9000 rpm skip/sputter/gear slip.


I would check the oil first, when your riding at 9000 rpms the bike working harder, if your low on oil the basics is for malfuctions. Check all your fluids, coolant would be the next one. If its sputtering, possibly the air filter could be dirty and need changed.
