Clutch on 08 HD seems to be slipping around 3000 - 3500 rpm

the problem is not your tuning, it is your clutch. Motorcycle clutches are maintained as light as possible to stop heavy pressure on your fingers. often when you increase hp, you must increase your spring pressure on your clutch plates so the first thing is to adjust your clutch, if it is too tight it will slip under load (more load = more slip). second,clutches do wear out so if adjusting does not work you will have to inspect your clutch plates for wear and may even have to increase your spring pressure, this is a big job and you will need special gear to do it

make sure there is 3mm play on the clutch lever , select 5th gear while engine is running and press the rear brake to stop you moving away ! with a little revs try and set off , if clutch is worn it will slip and not stall the engine ! if this happens then replace the clutch plates !

Very likely clutch plates I'm afraid.

Caution here: What oil are you using? If you have used standard Auto oil in the engine, it will have contaminated the plates and this is why they will be slipping. Bike engine oil is a different formulation because the clutch is submerged in oil. What you are describing is a classic result of topping your bike up with standard car engine oil.

If this is the case, you will certainly need to replace the clutch plates.

How is your clutch? Does it slip or drag when starting out? When you put it into 1st gear when starting out does the bike lunge forward? Hold it in first gear with the clutch in and rev the bike up. See if the bike wants to move forward with the clutch in.It sounds to me like your clutch isn't set right or getting worn out. Much easier to shift at low rpms on a clutch than high rpms. I hope this helps...

I've taken Jerry's class several times, advanced riding techniques each time and use them during numerous (15) parades each year. My 2000 Ultra Classic clutch has held up fine.

Some things to remember are: while using friction zone with slight pressure on rear brake (which really stabilizes the bike) is to keep the rpm's around 1500, not 3000. Also, after you practice for a while, ride around in 2nd or 3rd gear to cool down the bike engine and transmission.

The Motorcycle Police depts of Georgia and Florida all use this technique and they tell us the clutches hold up just fine for them.

it does seem to be low klm to be clutch wear,you may need to change your oil as if somebody put in a friction modified oil in at last oil change this can make the clutch slip,go to your bike shop and ask for your best oil match for your bike.try this first.it could also be as simple as clutch adjustment.hope this helps

If your rpms are going up to 7000 but your not moving your clutch is probally about to go out. Just make sure your clutch cable is not binding or stuck.

The latter part sounds like insufficient play on the clutch lever--the clutch seems to be slipping. Sudden power loss is usually linked to the ignition system. Have you checked the lube level in the transmission? You could be having a bearing seizure if the lube is low.

There are two clutch adjustments you can make. The easiest is under the rubber boot on your clutch cable, adjust that so you only have about an eigth of an inch of play on the lever. If that doesn't fix it the next adjustment is under the ball and ramp, lossen the clutch cable completely, remove the derby cover, disconnect the clutch cable from the ball and ramp then remove ball and ramp. You should now see a post with a slot in it, take a screw driver and snug it down then back it off about a quarter turn. Now just reassemble everything. If you still have the slipping problem you need a new clutch basket.

see carburator,there is screw to decrease or to increase rpm of motorcycle.
