07 Softail Trans clunck
I have an 07 Softail and I've noticed that the last couple of times that I had the bike out
I'm getting a cluncking noise after shifting the bike, also I can be going down the
road, let off on the gas and then hit the throttle and I'll get a clunck, not all the time, but
I have notice it more often, it seems if I keep the RPM's up higher it's not as noticeable.
It also seems to clunck more now going into 1st gear and all the other gears more now than
it did before.
Anybody have any idea's
Thanks for any input.

Probably the lash in the drivetrain..but check your clutch adjustment and your drive belt tension. If you are not running gear oil in your trans try some as it will quiet down some of the clunking. I run Redline Shockproof Heavy gear oil in mine. You can find it at www.myoilshop.com or get some Mobil1 75w140 gear oil from autozone as it will work well too.
If you run gear oil & your clutch & drive belt are adjusted correctly you may want to check your primary chain tension. But you should have an auto chain tensioner on your bike. Also, have you gone over the bike with a wrench and checked your engine mounts and other critical fasteners? Check your jiffy stand as well and make sure when it is in the up position it is not hitting the frame but resting on the rubber stop.
Hope this helps. KB

thanks for the reply, should I adjust the clutch at the clutch pack or just the cable, probably both would be the best.
Will check mounts and kick stand.
I am running Amsoil 75W110 in the trans.
If it's the lash in the drive train, how do you correct that?
Thanks

Don't get on and off the throttle hard. :^)
Check primary chain adjusment.
Try the Redline Heavy Shockproof oil... (in the trans)
Ride it like you stole it!
You're never going to make it far from the garage if you keep stopping to fix noises.

If all of this fails then do a critical fastener check: Front axle, rear pulley, fork pinch bolts, jiffy, all engine mounts, steering head, brake calipers. exhaust brackets, etc.
If that fails then you may want to pull the primary cover and check the compensator & primary chain. There are some issues with the 07 compensators but I don't know if the B motor is one of them. Get in touch with a member RBABOS here and he might know if your clunk is the compensator. If it is then you want to replace it with the Screaming Eagle compensator which is an upgraded unit. But Ron Babos will know.

That's perfectly normal lash and they all do it. Your shifting is sloppy in the fact you let it decel in the shifted gear and then add throttle. The result is a clack sound as the lash is taken up. Stop shifting like an old man and it will go away.

Guys, thanks for all the information, KB I will look into that SE compensator down the road.
but maybe Ron has a good point I am getting up there in years and maybe my shifting could be off a notch or two.
I adjusted the clutch tonight, but did not get a chance to take it out.
will do that tomorrow and I'll also keep an eye on my shifting, it's hell getting old.
thanks again guys, in a way I hope it is my shifting at least that way I know it's not the bike.

These traits are built in, so you have to live with them.
