realrayzor Posted February 2, 2011 Posted February 2, 2011 Howdy All,, i'm new to the forum and also new to bikes. I bought a yamaha xv500 about 6 months ago. Crashed bike so i have been fixing her up. The front wheel has a very slight buckle so when i drive her i can feel a bit of a shimmer. Not very confidence inspiring driving down the road at 50mph. I cant find anyone to fix the buckle can anyone tell where i can get it sorted.. Its a spoked front wheel. Dont think there is any problem with the frame or the frocks before anyone askes. Cheers Razor
Moderator mervin Posted February 2, 2011 Moderator Posted February 2, 2011 an intorduction inthe noobs would have been nice and a useful touch is too put your location in you profile, then people can advise you where to go for repairs etc relevant to your location as for ye wheel your best bet if it is an alloy wheel to find a good secondhand one, if it is a wire wheel then go too a wheel builder to straighten it
realrayzor Posted February 2, 2011 Author Posted February 2, 2011 Cheers Mervin, Ya just in the middle of updating the profile and i'll get round to saying hello also. I'm in Ireland. Haven't a clue what sort of business would fix a wire wheel. Would a standard bike shop have someone to do such a thing. Asked a few of my mates who are into bikes but they had no idea. Razor
ben40d Posted February 2, 2011 Posted February 2, 2011 When i plowed my dtr125 into a careless van driver my front wheel also buckled. When i took it to my local mech he sent the wheel off to a specialist. I'd imagine this is something most mechanics have encountered before and have a contact for. Although it may be cheaper to buy a second hand one from one being broken!
Moderator Cynic Posted February 2, 2011 Moderator Posted February 2, 2011 Here are 2 options, Central Wheel components are part of Bikers World which may be easier for you if there is a branch your side of the water. I may be using them myself if i can squirrel some cash from the missus to re-do my TDR wheels. Central Wheel Hagon Wheel building
Moderator Airhead Posted February 2, 2011 Moderator Posted February 2, 2011 How bad is it though, any flat spots or just a little out of true? The latter could be improved with a spoke key I suppose but if badly buckled you would need to have a hydraulic press to straighten it

realrayzor Posted February 2, 2011 Author Posted February 2, 2011 Thanks lads, I'll check out those web sites. The buckle is very small and hard to see with your eye but when you drive the bike you can feel it. Have n't had any look finding a second hand wheel, have been watching ebay like a hawk but no luck.
Moderator Airhead Posted February 2, 2011 Moderator Posted February 2, 2011 If its hard to see 1: you should be able to do it with a spoke key 2; I wouldnt expect it to cause any nervousness (shimmering) ? Maybe its out of balance, lift the wheel off the ground and does the wheel always turn to the same spot? brake drag can interfere with this test though and it is best done with wheel out if you have that. What about tyre pressure too, low pressure especially in the front can cause trouble as can play in the swing arm bearing
realrayzor Posted February 2, 2011 Author Posted February 2, 2011 Ha LOL. Thats forks not frocks. I dont have my bike kitted out in a little black dress.

What about tyre pressure too, low pressure especially in the front can cause trouble as can play in the swing arm bearing I'll take it off tomorrow and see if it is just the balance. I checked the tyre pressure and it all good. When i run a spanner across the spokes the spoke with the weight on does sound different but that could be because of the balance weight??? Razor

Razor if youre going to that trouble, mark the spoke with the weight and remove it (weight), do the test then fit the weight to the spoke always at the top...is it the marked spoke because it should be.

Thanks oldgitonabike, thats a good idea, i'll try that and post the results. Razor
Kelum Posted February 3, 2011 Posted February 3, 2011 Buying a new rim is pricey for you? Check ebay there were some ...
realrayzor Posted February 3, 2011 Author Posted February 3, 2011 Update on the wheel is: I took off the wheel and propped it up and spun it. It is very sligthly off through but its hard to think that i could have the shimmer ìt has when driving. I tried doing the test that oldgitonabike suggested and took off the balance weight and spun the wheel to see if it would stop at the same spot. To be honest i could not do it right. The wheel turned too easily and would make about 3 or 4 turns, it was inconclusive. Any other ideas. Thanks Razor

Hold the wheen on the axle (weight removed)...it will have a heavy spot thet will always come to rest at the bottom. No need to spin it, just rotate it each way 1/4 turn and let go
realrayzor Posted February 3, 2011 Author Posted February 3, 2011 Ha lol. I knew i was being a plonker. Right i get ya. I'll try that again tomorrow. But explain to me when i find the heavy spot,, what then?? Thanks again for your help Razor

But explain to me when i find the heavy spot,, what then?? Thanks again for your help Razor Like I said before, 1: first mark the spoke with the weight on 2: Remove weight 3: find where the wheel settles as just discussed 4: Fit the weight to the spoke at the top when wheel settled 5: This should be the marked spoke by the way or it was weighted on the wrong spoke 6: You can in fact repeat the test with the weight in place now to check it is the right amount of weight
realrayzor Posted February 3, 2011 Author Posted February 3, 2011 OK I'll give that a go again. Razor
2 Wheels Posted February 3, 2011 Posted February 3, 2011 Plus all your spokes should "Ping" to the same note when gently tapped with a screwdriver or the like. If you have a lot of tightening to do on the spokes then be prepaired for punctures unless you take the tyre off and file down the ends of the spokes !
