Yep, they all clunk. Some more than others. As mentioned earlier, try Redline Heavy Shockproof. Will probably help some.

I've tried RP 75w90, RP 85w140, and RL SP Heavy. No difference in clunk, and neutral to 1st is a healthy one. Otherwise I get clunks between gears, but not like neutral to 1st. Have gotten used to it. Primary chain has correct slack with auto tensioner.

I'm adjusting my clutch at 3/4-turn from flush. Would going to say 1/2-turn reduce the clunk? The spec is 1/2-1 turn. Anyone tried different settings and noticed a difference either way?

Yeah the old 4-speeds clunked, the 5-speeds clunked, and my '07 6-speed clunks, but not much now, and only going low to second. I put Spectro Platinum 6-speed gear oil in it. It's rated GL-5 which is for helical cut gears as in the Cruise Drive tranny. It reduced shifting noise dramatically. My S.E. 6-speed has straight cut gears, it clunked, I put Bel Ray 85-140 Hypoid Gear Oil in it, also rated GL-5 and it is way quieter too. You might try a multi Vicosity Synthetic Motorcycle gear oil and see if it helps. There are a lot of good ones, Red Line, Amsoil, and the 2 I use are highly recommended. I rarely wear a helmet and hear everything.

Almost the same for me but was my birthday present for myself when I turned 61. Man I figured it was LOUD - REAL loud.

Now, about 20K miles and a couple of years later it is still LOUD - REAL loud (and still working perfectly too ).

Yep, Northside is right .. the four speeds cluncked and everything since.

Personally, I really like it.
(a) I take it as a sign that there's big robust bits moving around in those cases because it will always clunk and very rarely break
(b) I love the look on the faces of car drivers next to you at the lights when you "clunk" it into first from neutral! Priceless!

Try this:

1) Start bike in N with clutch in

2) Hold clutch as bike begins to warm then, while still in N, release clutch (allow bike to sit in this mode for 30 seconds to a minute)

3) As bike warms, pull in clutch, quickly roll on throttle to increase RPM's by 2 or 3 hundred RPM's then release to idle (roll on a couple times)

4) While holding in clutch, shift into 1st gear and ride away

I've found that a couple quick twists of the throttle will help release the clutch plates allowing for a smoother shift. It doesn't work every time but 80% of the time anyway.

Good luck!

I have found also that moving the clutch lever in and out a few times on cold start up will free up the plates and make that first shift alot smoother.

1. Bike in Neutral
2. Pull in clutch lever
3. Start bike
4. Two quick twists of the throttle
5. Mash down on shift lever...................No Clunk

........works for me about 90% of the time.

Now, through the rest of the gears....clunk, clunk, clunk, clunk, clunk
Thats what I love about a Hawg. You can see em, hear em and feel em comin'!!!!
