have been out with my son as as a passenger yesterday again. When I fully open the throttle at about 40mph the wheel starts spinning, and it seems that when it hooks up again for full forward acceleration, I hear a strong "crack, crack, crack". I have had this slightly a few month ago and thought that the belt wolud be slipping. Adjusted it to 500+lbs now, and still with the passenger on this happens. Not really when I do this alone.
Any ideas ? :idea:

Peter,

Check to see if your hitting the rear fender where the center bolt goes through or at the left front edge.

Peter,
If the belt slips you will not mistake it. You will FEEL it jump the cogs. Also it may not be a bad idea to keep the tension closer to 425-450. I was recommended that by Nesco on my one speed. Better on the bearings for long term use. If dragging or alot of playing maybe go to the higher tension. Just my 5 cents. (inflation)

Tim,
checked the fender last night, but there is plenty of room. I am (still) running the stock 230 Avon and have the spring tension up high (18 "rings" without the fastener). Also with a passenger the damper to 6. I am affraid its something mechanical, like a bearing or so. May be I "need" the 3" belt :roll:

Glenn,
if that higher tension does not help, I will go back. I think 450 is the highest the manual recommends. (inflation is pretty high)

Peter ,

Could the noise your hearing be bad rear wheel bearings or your rear axle is not torqued to the recommended 15 lbs ?

Per Jim Palmer at NESSCO you should be ok with the belt tension to 550. Mine was slipping at 600 so I went to the 3in belt and at 475 it will not slip!

I'll tell you what that much tension is hard on and that's the swingarm bushings. I have seen a few egg shaped on the left side. :roll:

Jack,
tried to check the torque at the rear axle last night and found that the nut there (1 7/16" ?) is far to large for my little tool box Have to go out and get one first. I will have to change the tire in the near future so I will check the bearings etc. If that is all okay I will try the 3" setup like Busa Dave recomends. Also looked at the manual again: 400-500lbs is recomended.

Peter,
I don't have such a big socket tool either. I use to take an "Englander" for the rear axle nut. I think you as a Krauty know what I'm talking about.
I think the american word for this tool is "monkey wrench" (?) - that's an adjustable wrench.

I adjust the rear axle nut/bearings the same way like I always did it on my cars. I tighten the castle nut until I feel no end play in the whole rear axle unit (not too tight, otherwise you would destroy the bearings). Then I LOOSEN the nut back one notch - just enough to push the small splint thru the nut and axle.

I found out that 15 lbs weren't enough on my Boss, because my rear swing arm give some amount of pre-tension to the nut. Or - better explained - if I torque the nut to only 15 lbs, then I still have lot's of end play in the bearings. So I don't care about the 15 lbs, and torque the nut until I feel it is tight (I also turn the rear wheel slowly while I tighten the nut to make sure the bearings set perfect in the cones) - then I turn it back one notch. I always did it this way, and it worked always fine for me.
Don't miss to clean the bearings, and fill them with fresh grease. And use new seals - they are cheap.

Hmmmm...now that I write this all....I think you've got a 2003 model....do the 2003's have cone bearings at all? I know they changed the bearings a while ago, but I'm not sure when they did that....

If so - regular bearings might need a lot more to be torqued- what does your manual say?

"03 have the new style bearings in them.

I use the "Kraut" torque method on mine also and have had no problems.

Cracking

Peter;

How about a followup on the fix for that problem please?

I'm still new enough to the Boss to need to LEARN a lot!

It seems my Boss' pedigree is spread out over at least 4 if not more year models.

Thanks

Ride Safe.

Jack,
unfortunatley the weather has not cooperated in the last few weeks. We had tons of that white stuff laying arround and still is. Very unusual for our area. Lots of outdoor events already have been canceld.
Adjusting the belt, I found that by turning the belt just a bit, that I get different readings.(+/-30lbs) May be that the pulley or a bearing is a tiny bit out of spec. Probably hard to see, when you think how much difference a 1/8th turn of the adjusting screw already does. So I carefully adjusted it to 500lbs now to make sure it really is 500. Since I will be in Portugal over Easter to put a few thousand miles on my GoldWing , I wont be able to test it before mid of April.

Peter,
It is a long shot but check your pully for wear and also your belt for wear. It will hop easier when warn.

Had her out on the weekend with a good 500lbs. No cracking. So it seems to me, that I need the higher tension.
I will have to change the tire in the fall (latest) and will check every single part then.
So far so good.
