redfjniner Posted May 23, 2015 Share Posted May 23, 2015 I am mounting a new tire on the front of the FJ and didn't like the number of weights it was requiring, so I took the new tire off and checked the balance of the rim alone. It will require just over 70 grams to balance the rim. I originally took off the 40 grams that the bike came with. I installed a new tire and it was looking like 50 grams to balance. I didn't like that so I broke the bead and rotated the tire and tried again. This time it was looking like it would take 65 grams. That is why I wanted to check the balance of the rim. The question is, does anyone know what the manufacturer's tolerance is for the cast wheels? Ken, Candy Ass L.D.R.

Premium Member wessie Posted May 23, 2015 Premium Member Share Posted May 23, 2015 seems at least 60g as my bike has 2x 30g lumps of lead substitute crimped onto the wheel This signature is left blank as the poster writes enough pretentious bollocks as it is.

hotboot Posted May 24, 2015 Share Posted May 24, 2015 I wager there is no manufacturing tolerance, just wheel weights to correct. That is a lot of weight. I have to check mine now that you brought it up, I sure have a high speed imbalance up there weather wind harmonics or weird wheel balancing it is noticeable. Get it as perfect as you can and let us know if you have issues. Link to comment Share on other sites More sharing options...

Near the end of the D222, I noticed a steering wobble at 45-50 when I let go of the handle bars, but this is normal as due to scalloping of the tread. I also noticed a slight high speed shake around 100mph a bit earlier. The stock tire used 40 grams of weights. My dealer says that they don't worry about it until the weights reaches 90grams. If I was doing 100+ all the time, like racing, I would be more concerned. Ken, Candy Ass L.D.R.

stephen Posted May 24, 2015 Share Posted May 24, 2015 Also checked mine, has 2 X 30 plus 1 X 10. I have a lot of vibrations coming through handle bars. So bad that my hand goto sleep (pins and needles). Wonder could this be contributing to these vibs... Am seriously thinking these vibrations should be a safety recall as after tens miles my right hand is so numb I can't operate front brake efficiently... Yet on my old TDM with 50000 miles on clock I can ride all day.... Link to comment Share on other sites More sharing options...
snowflake Posted May 25, 2015 Share Posted May 25, 2015 My front wheel has 2 20g weights, the rear: none. Go figure Link to comment Share on other sites More sharing options...

Maybe we can do something about this. Also, relax your grip to reduce the effect of the vibration on the hand. If it continues, you need to get a throttle lock to be able to just rest your hand on top of the grip. A palm rest is also useful. I use both of those. Ken, Candy Ass L.D.R.

Premium Member wessie Posted May 25, 2015 Premium Member Share Posted May 25, 2015 It may not be the wheel - it may be the brake discs that cause the imbalance - might be worth taking the disks off then checking the balance. If the wheel is true without the brake discs then you could try rotating one of the disks to get a better balance.

beberle Posted May 28, 2015 Share Posted May 28, 2015 60grams here. Not much room for any more weight! Link to comment Share on other sites More sharing options...
Guest reeseyboy Posted June 3, 2015 Share Posted June 3, 2015 Interesting. When I had my PR3's mounted a while back, my fitter said that he was struggling to get the wheel balanced. He removed the tyre and it took 80g to balance the bare rim. Tyre back on and it's taken 100g to balance. The casting is miles off and the machining doesn't look much better. These are short clips of either side of my front wheel on a static balancer. I have shown my dealer this and we are (still) waiting for an answer from Yamaha...

beberle Posted June 3, 2015 Share Posted June 3, 2015 Wow, that's crazy. In this era of CNC and quality control, no way these front rims should need any weight to balance before installing the tires... Link to comment Share on other sites More sharing options...
vespadaddy Posted June 3, 2015 Share Posted June 3, 2015 Wow. That looks all the world to me like an out of spec rim. Look how the horizontal band shrinks and grows around the rim as it spins in video #2! That *cant* be in spec. Can it? Link to comment Share on other sites More sharing options...
redfjniner Posted June 3, 2015 Author Share Posted June 3, 2015 Thanks guy for posting up your issues regarding the front wheel casting. We need to keep on this or get on it with Yamaha, as if the casting is really out, we should get a new wheel. I think. Although, I have no issue at 100+ as everything smooths out. Just turned 13,500+ miles today. Ken, Candy Ass L.D.R.

fj09max Posted June 8, 2015 Share Posted June 8, 2015 My tire shop struggle to balance the front tire. New PR4 installed today. They remove all the weight and put 2g of balace beads in the front tire. Haven't reinstalled the tire yet and it's raining outside. Is somebody already tried those tire beads?
