I can eard a metallic noise from the front wheel. Since 2 weeks I'm looking to find where he can come from and now I think I've found and I'm a little bit frightened. This noise is comming from the front break disk they are moving in the screw place. See the picture Have you ever see this problem ? Is it Normal ?,I think it's normal mate. Semi floating or floating discs are fitted so they do move. Someone more knowledgeable will be along soon I'm sure to confirm or correct me!,,,

The situation that you describe does sound like a rake based issue. Low tire pressure makes it much worse. Aside from lower speed annoyances, this design will be much more stable on the road, as speeds increase. Unlikely that something is wrong, or you would have lots more issues.

Thanks for the inquiry!
From your information I can't tell if this is a off-road bike or a street bike. With the extended swing arm I'm suspecting off-road. In either case it's very much same issues. You have two issues and we will deal with them separately.
Chain catching sound:
In low gear when you have maximum torque applied to your rear sprocket & wheel many times the primary sprocket (smallest one under the engine side cover) will slip and actually jump teeth. You indicated this is the third season, so it's seen a lot of wear. It would also explain that when you adjust/ tighten the chain tensioner the noise is gone as the front sprocket is not slipping in the chain. If this happens a couple of times the front sprocket is ruined. Pull the front sprocket cover and inspect the teeth. The teeth will be smooth and ground away if this has occurred. Most off-road riders go through 1 - 2 sprocket and chain sets per season with the abrasion form the sand and mud if they are serious about their riding. Replace front sprocket or both sprockets & chain.
Other possibilities are that you have lost your chain guide or the plastic wear plates inside the chain guide are gone and the chain is banging against the metallic sides or your swing arm making the chain jumping sound you have described. Replace the guide or wear plates to solve this.
Whooping sound on front of bike while coasting: This familiar sound appears to be related to your front wheel. The best way to test this is to set your bike on a bench, crate, or test stand so the front wheel/tire is off the floor/ground and spin the wheel. Your rim may be bent allowing the tire to rub against the fork tubes or front fender making the whooping sound. The engine noise drown's it out under power but noise is audible when coasting with the clutch in and engine idling. The simple fix is a spoke tightening and adjustment to properly true the wheel. You will hear if its a bearing or something else being rubbed against by a wooble or something out of round (run out) causing the whooping sound.
I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.
Please post a comment if you need additional assistance so that I can help you further.
Happy cycling,

1999 harley roadking rear and front axle torque specs??


Use loctite on the threads of all parts. For the front, holding the axle with a tool in the hole, tighten the axle nut to 50 lbs.

If your bike has dual front disk brakes, you need to insert a 7/16 drill bit into the hole in the axle. This step is necessary to give the proper spacing to the brake discs. Loosen the pinch bolt at the bottom of the fork. Move the fork so the drill bit rests snugly against the side of the fork. Now tighten the pinch bolt making certain the drill bit still contacts the side of the fork.The pinch bolt should get not more than 30lbs.

for the rear, the axle gets 60 lbs. If you loosened the shocks to make room for the wheel tighten those bolts to 35lbs.

I sure hope you kept all the spacers and washers in their correct positions.

Here's hoping that gets you back on the road.

Ride safe, ride longer.

I noticed that both my front and rear wheels are not spinning freely and that it appears that the disc brake pistons have not fully rectracted. Is that something that a diy mechanic can tackle? I've...


The first thing tp try is a simple pressure wash of the calipers just in case a little dirt is the cause. Wheel lock up surprisingly is normally caused by dirt in the master cylinder. There is a large hole in the master cylinder that feeds the brake piston in the master cylinder. Right next to large feeder hole, is a pin hole that is the brake fluid return passageway. If the pin hole becomes plugged with dirt or rust the front wheel will drag or even lock up. A simple cleaning of the master cylinder will often fix the lock up problem. If the machine is older consider replacing all of the rubber parts and refilling the system with fresh DOT 3/4 brake fluid.

Hearing a scraping noise about 15 mph , replaced front wheel bearing


The scraping noise could be a brake pad rubbing on a rotor, most likely caused by not getting the axle set in the right spot after replacing the wheel bearings, (assuming everything else was done correctly). Start by supporting bike with front wheel off the ground. Loosen the front axle nut. Loosen the clamp on the bottom of the right side lower leg. Insert a 7/16" drill bit or steel rod or drill bit, (whatever will fit through the hole without too much slop). Tighten axle nut to 50 to 55 ft lbs. Tighten clamp nuts. Spin the wheel and operate the hand brake a few times. Wheel should now be centered with the brake rotors running in the center of the brake pads. If not, you may have mixed up the spacers.

Hot brakes


my front disk brake was hot. When i parked my bike in front of my house I heard that dissipating heat ticking that would normally be associated with a hot engine only it was my front disk. This was just from everyday ride through town. I never noticed if car rotors got hot so I have to ask if its normal for a bike rotor to heat up after some use? It was too hot to feel with your hand but not glowing red or smoking. Nor did it give the aroma of toasted brakes.It will generate heat normally. Lift the front end and spin the wheel to see if your pads are dragging.,,,

Twisted forks


and when the forks/bars/tripleclamps are straight the wheel goes towards the right. ii think they are twisted or bent. how much do new forks cost?Loosen your front wheel slightly. Loosen your fork clamp bolts on the triple clamps slighty. Hold the front brake lever. Put one leg on either side of the front wheel to keep it from moving. Use the handlebars to turn the front end back straight. Tighten everything back up using a torque wrench and torqueing to the proper values from your service manual. Go ride and have fun. ,

Need advise about truing a front wheel


but I mention Aprilia and they run for the hills. Seems like most people only want to work on Hondas and Harley's. Does anyone think that this is a project that I should try myself? Or is there anyone out there that knows of someone that could do a perfect job?I just got through dealing with the same problem. I even got a new wheel and it wasnt' true. The dealer couldn't true it because the wheel is too rigid. I found one of the best businesses I have ever come across during my search to get the wheel fixed. The company is Woody's Wheel Works in Colorado. I shipped them my wheel they trued it the day I got it and shipped it back out the next day. They are a great bunch of guys. The site is www.woodyswheelworks.com. ,,
