How do you know the clutch is blue unless you have had it apart. If it is blue it is overheated and you need to change the parts out for new ones. It is likely slipping if blued. Make sure it gets done right and adjusted properly when you rebuild it. Can be just as cheap to just buy the whole clutch as an assembly.

You were supposed to put 4 ounces into the filter before installation to prime the system.

SOURCE: Chatter noise from primary drive case when

Sounds like you need to clean the clutch plates. This is rather unusual on the newer bikes but quite common on the older Shovelhead bikes. Make sure you're using the correct lubricant at the right level in your primary.

The clutch disc can get a glaze on them. We disassemble the clutch and wash the fiber plates with gasoline. Yes, I know gasoline is dangerous to use as a cleaning solvent due to it's flammability. Just be careful as it is the cheapest solvent that will cut the glaze. Mineral Spirits or diesel fuel won't work. Make sure you notice how the clutch plates are postitioned in the clutch basket. The middle plate is usually a spring plate. Once cleaned, lay a piece of fine emory cloth on a flat surface and sand both sides of the fiber disc using a figure 8 motion. Not much, just enough to knock the remaining glaze off the disc.

Now, put the clutch back together and adjust it properly as improper adjustment is probably what caused this to begin with. Back off on the adjustment on the clutch cable. Make it as short as possible. Now, in the center of the clutch pack there is a screw with a locknut on it. Break the locknut loose. Adjust the screw inwards until you feel a resistance. Then, back the screw back out 1/2 to 1 full turn. Lock the lock nut back down. Now, adjust your clutch cable so that you've got about 1/8 inch freeplay at the clutch lever. While you're in the primary, check the adjustment of the primary chain if your bike is equipped with the manual adjuster. Good Luck.

SOURCE: I have a 2004 Duece

Did you check your front belt pulley? These pulleys are made of relatively soft cast iron as compared to the final drive gear. This is so that the easily replaced and relatively inexpensive front pulley wears before the difficult to replace and expensive final drive gear wears. The pulley will wear in the splined inner bore and will get loose on the final drive gear. Then transmission oil will run out of the pulley and down the inner primary. This is because of the lose of pressure on the "Quad" ring behind the pulley spacer. This may be your problem.

Another mistake a LOT of people make when replacing any seal is putting the seal up dry. On the inner primary seal, you want to put a bit sealer compound around the outer edge of the seal where it goes into the case. Although there are a lot new sealants out there, I still prefer good Permatex non-hardening. Once you get the seal in and straight, oil the inner seal surfaces and the bearing race. If you put the seal up dry, you start the engine, the mainshaft turns about 1000 rpm. This will burn up the delicate rubber lips on the seal almost instantly because of friction before the oil can get to the seal. You MUST lubricate the seal or it WILL burn up before you can blink an eye.

Also check the position of the inner primary bearing race. It must be 0.100" from the final drive gear. If it's way out of position, the seal may not be riding properly on it.

If you are in doubt about whether the transmission is leaking or the primary, refill the primary with a quart of automatic transmission fluid, the red stuff. It will work long enough for you to determine whether it's the transmission leaking or the primary leaking. If it's the transmission, check the front belt drive pulley for wear, You'll usually find that the large nut that holds it on is loose.

Good Luck

Why is 1991 FLHTC clutch siezing . seems like motor and clutch are seizing?

Do you mean chattering? Does it vibrate the whole bike violently when you try to take off from a stop? Like it won't slip smoothly, instead it grabs/releases almost like it has teeth?

Clutch chatter can be caused by oil contamination [of the clutch surface], glazed pressure plate and/or flywheel, broken clutch disk spring and/or bad throw-out bearing. Loose mounts or binding anywhere along the clutch cable and linkage can contribute to it as well, and there are machines that are under-engineered, with clutches that are just born to chatter.

As you've surely guessed the only remedy is replacement. If this is a common or recurring problem, look for after-market parts that address the problem.

Oil in primary on 1988 1340 harley

Use Harley's Formula + or Syn 3. If you use Syn 3, which is synthetic, you can use it in all three cavities, primary, transmission and motor. DO NOT put regular 20/50 in your primary or trans! When adding oil to the primary, fill it until the oil touches the bottom of the clutch with the bike standing upright. It will take a little less than a quart.

Just got a 02 road king. first 88 inch motor. were do i check and fill motor oil. is the motor and trans oil the same?

The engine oil tank is on the bottom of the transmission. On one corner of the transmission there is a large 2" diameter cap with knurling on the edges. Pull this out and you'll see the oil dipstick. Check the oil with the bike on the side stand. Lower mark is FULL COLD, upper mark is FULL HOT. do not overfill. Capacity with filter change 3 quarts.

The transmission oil is separate from the engine oil. On the right side of the bike just behind the exhaust system is the chrome clutch release mechanism. It has a plug in it that takes a 7/16" Allen or Hex key wrench to remove it. With the bike standing straight up, the oil level should be between the two marks on the dipstick. Capacity 20-24 ounces

The primary also has oil in it. With the bike standing straight up, remove the round "derby" cover. Inside is the clutch assembly. You'll see a bright ring around the clutch assembly with the dark clutch spring inside. Fill the oil just until it touches the lowest point of the dark clutch spring. Do not overfill. Capacity, 36-42 ounces.

Good Luck

Is there a certain brand or weight of oil I should be using in my 06 sporster 1200 custom?

20w/50 synthetic

04-up is 3 qts.

Drain oil hot, r&r filter, put in oil,........let a couple ounces drain out of the hose to bleed the air out to prevent cavitation inside the oil pump.... run engine about 10 minutes, shut off & let sit for about 2 minutes. Check oil level with bike upright, oil should be at top mark on dipstick, fill as needed.

Don't forget about the Primary Oil...1 qt.

Also remember, there is WAY more to maintaining your bike than just an oil change, belt tension, throttle cable lube and adjustment, clutch adjustment, clutch cable lube and adjustment, primary chain adjustment, brake inpsection, tire pressures, fork oil every 10k miles, steering neck bearing lube and adjustment every 10k miles, etc.

When i accelerate hard on my cx500 eurosport the clutch goes solid and i cannot change gear until i slow down ,any ideas ?

Change the oil and oil filter. Ride the bike for 50 miles or so then change th oil again but w/o another filter. Dirt and grit in the oil is making the clutch grab and not fully disengage. Changing oil will flush the gearbox. 10w40 motor oil.

Please rate this solution. Thanks bloohart!

2007 XL883 Oil Change

the sportster differs in that there are only 2 holes compared to the 3 on the softail. You drain the main oil via tube at the rear of the engine and the primary/trans with a bolt under the bike make sure you get the correct one as its close to the adjuster for the primary chain. you need 3qts for the motor with a new filter and 1qt for the primary/trans use the forumla+ or Spectro sporty heavy duty primary/trans in the primary and your choice in the motor. whilst your servicing it make sure all the motor mounts are tight and the fuel and oil lines are leak free and get the dielectric grease onto the fuse block and relays and adjust the primary chain
