Exclamation Please Help Diagnose My Problem!!!!

Hello, I was out this evening riding my 2010 Wide Glide. I stopped at a redlight halfway up a hill. When the light turned green I started to accelerate up the hill. In 3rd gear I noticed a hesitaion (like the power wasn't getting to the rear tire). I noticed throughout the ride tonight that it did it a few more times in the higher gears. It feels and sounds like the engine is making power but it's not getting to the rear tire. (it will hesitate and then jolt forward).

My first thought was the clutch slipping, I also thought it could be bad gas but the engine cranks and idles fine.

This is what I have done recently to the bike when I started to notice the problem:

2.5 quarts Amsoil in engine

1 quart 20/50 amsoil in primary

1 quart severe duty amsoil in trans

Shimmed front engine mount 2 washers on top and 2 on bottom.

Thank you very much for the help and info. I take pride in my bike running 100%. It makes me sick to my stomach when it's not. Thanks

if there's no sputtering in the engine at all, then i'd agree and say it could be your clutch

I did the primary oil change per the service manual. I did really notice the problem after the primary oil change. I thought amsoil was supposed to be better???

ive heard on a few occasions that 1 qt is to much to put in the primary. possibly the problem? Try draining some...not much though. Before you do that though.. open up the primary inspection and see where your oil level sits. It should be about touching the bottom of the chain.

it is possible that there are additives in the oil that dont agree with the clutch material.

I think Amsoil is a great product, its in my engine now, but i only run the HD spec oil in the primary.

for the forums sake, change it out and let us know.

I am thinking of doing that, I love the way Amsoil makes the engine and trans run but it seems almost too slippery in the primary.

Just another note: It seems fine when I am just scootin around. It seems to only slip when under load or hard acceleration.

Thanks again for all the help.

Default Oil

I dont run synthetic oil in a wet clutch. I use castrol 20w50 (1qt) in primary. I can beat on my clutch at the drag strip and it never slips. Synthetics has ruined a many clutch packs in my Jap bikes. You can get away with it if you run a tighter clutch spring ,but I dont do it.
You need to make sure that you have a nickels width of free play at the clutch perch. Indicating you have some slack in the cable as well. i would change the oil and check slack. Should fix it up.

If you let the clutch slip like that for anything more than one or two times the clutch plates will probably be glazed and require dissassembly and sanded or replaced. Depending on how they measure out when removed. They never grab as good as they did before they were overheated. I have patched up clutches like that before, but only until I was able to snag a new set of fiber plates to replace em.

Only ever use wet clutch / bike specific oil in the primary. Engine oils have friction modifiers in them which can somtimes make the clutch slip. Drain it out and replace with HD primary oil or a bike specific engine oil (for combined engine / trans bikes) and see how it goes, you may have to drain and replace again after a few miles to flush out what's left in there. If that doesn't cure it you'll have to strip the clutch plates out and scrub them up.

If of course that's what your problem is, difficult to diagnose without seeing the bike but it sounds like a feasible conclusion

Default Primary

I would use H-D Formula + in the primary.

Synthetic JASO MA Motorcycle oils don't have Viscosity Index Improvers or friction modifiers in them. If you just tossed in some Amsoil that wasn't JASO MA (MA means 'motorcycle approved') it could be causing your problem. But I'm not totally sold on that being the problem. It could be, however.

The primary usually takes a couple ounces less than a full quart (if you drained the primary completely). But if you over-filled it, I don't see that as the problem either. It would just start puking oil from somewhere.

It could be your clutch is out of adjustment. Either at the lever or the clutch pak itself.

If you're certain you used the proper JASO MA oil, I'd check the clutch engagement at the hand lever. If that's not it then you may want to tackle the clutch pak adjustment.

Meanwhile, don't burn your clutch up.
