Disc brakes???
If yes, you probably hav a frozen caliper. These are re-buildable. I have had good luck by removing the piston, cleaning up the piston and the bore, and lube the piston up and re-install with no parts. But the procedure requires an experienced set of hands.

Front wheel doesn't spin freely and squeaks on 2n'd day i got it.


Hi James:
If New, I'd take it back to the dealer.
If used.....
Set bike on jack so front wheel is raised. Make sure it is secure so can't fall.
1) Remove front brake pads........... spin wheel If it still squeaks, remove wheel and service bearings.
If no squeak when brakes removed, service brakes.

My kx 80 (1992) starts and revs up nice but wen put into gear it hardly moves, the heavyer the person trying to ride it the less it goes, when I lift the back wheel off the floor (no pressure on engine)...


Front wheel drag (locked brake).Bad tire air pressure.If not,is carburetor cloged,need to drain (bolt under) or remove to clean.If the motor revs in the gear ,the clutch slip.Could be bad clutch cable tension or need replace clutch/cable.

When I hit a bump,or roll the bike forward and put the front brake on hard,I get a clunk from under the tank.Steering is tight,and so are the fron calipers


This is an indicator that the steering head may not be adjusted correctly. The only way to tell for sure is to jack the bike up and take the front wheel off then check for play in the bearings of the steering head. If you think you may have something loose under the tank, then you'll have to take the tank off to check for something moving around under there. I won't take a guess at what it could be since you didn't tell me what year and model bike it is.

Good Luck

I have problem with my clutch in my 2004 Susuki Intruder. I put it away last year it was working fine I went to take it out and the clutch does not work it will go into grear but the clutch wont disengage


G'day. I can definatly help you with this.This is a problem I have come across many many times in my career as a motorcycle mechanic.It is a very common problem for bikes that have been sitting around for a while.What has happened is that all the clutch plates are stuck together. There are two ways to rectify this problem.One is to remove the clutch cover, remove the clutch springs,then the plates-noting the order- clean, re-lubricate & re-assemble.
The other way- which I have sucessfully used in 98% of cases is to start the bike in neutral,chock the front wheel- I position the bike with the front wheel against a brick wall or good size tree for a dirt bike,hold on the front brake tightly,rev the engine & hold at about 2000 rpm,click it into 2nd gear.CAUTION- The bike may jump forward &/or stall(get some friends/helpers on each side as "catchers" if your not too confident) Try this a couple of times if necessary & it usually works. Also you could try riding the bike with some front brake applied whilst pulling the clutch lever in & out several times.(This seperates the pressure plates whilst the clutch basket is spinning & can let the oil acess the fibre & steel plates whilst there not under pressure).
I hope this helps you.
Kind regards Andrew Porrelli

Son's can pedal 12" bike


Yes, something isn't turning freely. It's either the front wheel, the back wheel, or the pedals and chain. Lift the bike off the ground and turn the front wheel by hand. If it doesn't turn very freely, it could be the hand-brake is dragging or the hub bearing is too tight. Try the back wheel in both directions. It should move freely in the forward direction. When rolling it backwards it is normal for the pedals to move too if this bike has a coaster brake (that is the kind of brake that is applied by pushing the pedals backwards.) It the back wheel moves forward freely, but backwards is a problem, then try the pedals by hand with the rear wheel off the ground. If this doesn't turn freely, the pedal crank bearing (a.k.a. bottom bracket) is too tight. Once you have identified the problem take it back to where you got it. It should be easy to fix, or they should replace it.

Avid Juicy 7 disc brakes:The front wheel was removed and the brake lever squeezed while the wheel was off. The front wheel goes on, but does not spin freely. It turns easily, but not freely like it...


It sounds like you have a piston that is not fully returned and is sticking.

Get a big flat bladed screw driver, take the wheel out and very carefully insert the screw driver into where the disc would sit and use the screw driver to try and push each brake pad back in without damaging your brake pads.

If this works go to a local bike shop and ask them for a avid brake insert for transporting your bike so this does not happen in future! :)

Front wheel wobbles


More than likely the wheel is out of true. There are 2 choices,

1 Buy a spoke wrench and attemp to true the wheel. You can do this by spinning the wheel to locate the spot where the wheel goes furthest to one side then tighten the spoke coming from the opposite side. Do this slowly 1/2 turn at a time. Do not over tighten the spoke. It may be necessary to loosen the other side slightly.

Alternate spokes between both sides of wobble.

2 Take bike to a good local bike shop to be tuned and have the wheels trued. Most shops offer a tune up at low cost. A well tuned bike will last a long time.

Brake pads too tight in front wheel


Hi welcome to fixya.com
You have a 1992 cbr250 sounds like it could be 1 of 2 things . take off pads and spin wheel ,look for bent front disk. 2nd is you may have a frozen caliper. Remove brake resivoir cap and remove caliper.sLowlY depress brake caliper piston ,it may overflow resivior,so get some onte to assist so it doesnt spill, you may just need to replace fluid,if you can get the caliper unstuck. I would recomend getting new caliper, lines,and front disk,especially if you plan to use the bike. Its a nice bike ,unfortually these parts just reach there wear limit sometimes. Hope this helps or gives you more to try to solve your problem. Thanks for your support !

Childs 12 inch mongoose is new, but back wheel does not spin prop


The bikes are pre-assembled by a machine that overtightens the rear axle.  I had the same problem with my daugher's 12 inch huffy princess bike and my other duaghter's 16 inch Schwinn bike.  If you loosen the nuts on the back axle it fixes the problem.  I have read that the idea thing for these bike is to have them re-assembled and re-lubricated by a bike shop, but I thought this might cost as much as I paid for the bike.
