Tire rub on SM conversion. Need some help.

Just got the new excel/talon wheels, built by white bro's (sold by motostrano), and I'm having some chain rub problems.

I've read a number of threads on the issue, but nobody ever follows up when they fix the problem and tell what worked. I've PM'd, but no dice. Called Motostrano, but they can't help me until Monday.

The tire is a Distanzia 150/60R17. I know its a spacing problem. I suspected it at the very beginning when I discovered that the rotor side of the hub was about 1/4 - 3/8 in. out from the edge of the rim. I've read its supposed to be EVEN with it.

I need to pull the wheel to the right at least 1/4 inch or so an I'm just looking for some info on: 1: can I do it myself or do I need to pay a wheel builder 2: how to do it myself.

Also, has anybody had luck after installing the "SM" chain guide? I know this is primarily a spacing issue, but wondering if the chain guard has worked for others too. I don't know if its just my bike or what, but that chain seems to shake like crazy on the road.... It is because its a single cyl?

Thanks in advance.

Not too hard, but it easy to F'up if you are careless.

What you want to do is loosen the spokes on the sproket side 1/4 turn, then tighten on the disk side. When you look at your wheel, you'll notice the spokes are in groups of four. Start at the valve stem. When you get back to it, you will know you have done them all. Loosen four on one side, tighten the four closest to them on the other. Repeat. After you have done the wheel once, recheck it for true, side to side and up and down. Check the offset. If need be, do it again.

That a good trick to know. I will remember that one for sure.

My tire looked a lot like yours. It seemed like it should've been clear, but I guess the chain bouncing around contacted the tire on occasion. I took my wheel into a wheel shop to have it done. It was pretty expensive, but I didn't trust myself to mess with it. I think I ended up paying about $90.

I had to move my SM rim over a bit. Its not as hard as you think. Just do what William said, nice and easy. If I did it, anybody can. Chain still hits a bit bit it doesnt bother me. I run the 150 Distanzia.

That is a good idea... and I was about to do it when I thought about it a little harder... I don't want to screw this up, and I'm so frustrate about it that I most likely would. I know I could get it close, but not perfectly "true". paid $1200 for these wheels. They sure as hell better fit. Motostrano is supposed to call me on Monday. I think I'm just going to ask for them to take the rear back, space it correctly, and retrue it. :thumbsup:

Truth be told, Not only did you did you pay for the correct 'fit', if you are not comfortable doing this, then by all means have the Motostrano correct the issue. I too would probably return them if I were not time pressed or anything. Why should I do somebody else's job? When you get it back, typically, the rim is parallel with the rotor flange. FYI, this is called 'Offset'. :eek:

Same thing happened with mine but I added a little air to the tire. I heard that if you did this you had to dismount the tire and rim and cutoff and grind the tips of the spokes because they would poke through the tube and cause a flat.

Like William said loosen on the drive side & tighten on the brake side. My first set rubbed so bad that the rim had to be replaced as the builder didn't off set it enough. They stood behind their product & replaced the rim, relaced & trued it with the proper off set. I loosened all the spokes on the drive side 1/4 turn then tightened the brake side the same 1/4 turn that I loosened the drive side. I did not have any problem by not doing them in groups of 4. Just go completely around. I ordered the SM chain buffer today I will put it on. I will pay for the extra protection to not trash a $700 rim.

Did Motostrano correct the issue?

I offset mine 1/4 turn, & added the SM chain guide. It doesn't hit my Conti. Force SM 150. I can't say if it was the chain guide or not, but I'm sure it helps. It was a PITA to install. The SM has a different swingarm.

FYI, the pic is of a 160 Distazia. I cut the edge to see if it was still hitting. It was , but not as bad.

      Anyone’s air box smell like gas ? Is this normal ? Air filter is bone dry but it reeks in there .... I’m assuming cause of the carb being semi filled with gas ??

      So I’m reading these horror stories of the stock vacume operated petcocks failing and letting gas into the oil .... how many of you guys switched over and is it worth it to switch to manual ?

      Hey guys . I feel like I post here way to much lol 
       
      anyway after having my bike kn it’s side overnight to fix a cracked stator cover .... I come to find out that I also accidentally left the pet cock in the prime position .... constant gas flow to carb ... now my oil smells strongly of gas ... my question is ... was it the bike being on its side that made the gas get into the oil or the prime position on petcock that made this happen ? Or both ? I didn’t ride it much at all after discovering... I assume. I should drain the oil obviously but any other suggestions ? Always appreciated -mark

      Hello all, first time poster. Just bought this bike a few days ago it’s an 08 drz 400sm and am starting to notice it has a strange backfire at idle. I understand a little bit at decel might be normal, but at idle too?  It appears to have been jetted already, judging by the fact it has a jd jetting sticker on the bike itself. I know that it’s not an exact indicator it has but it could be. Has an FMF exhaust, it looks like a full system rather then a slip on but not entirely sure. A buddy recommended I mess with the air and fuel screw, haven’t done that yet. Just wanted to see if there was any other tips I should try.
