Guest Posted February 25, 2008 Posted February 25, 2008 My baby runs a sweet as a nut (not my words...the last garage i put her into), but under load while driving she makes a noise similar to someone hitting the frame with a hammer. Its not chain or sprocket derived and the wheels are firmly attached. There is no power loss nor hesitation in acceleration, no metal in the oil or shavings else where...........she is a triple, triumph trophy 1996 ...and i love her to bits....anybody have any ideas before i reluctantly have to take her to a triumph dealer Sad god help me! ...or someone else.thanks Gordon Quote
cyberwolf Posted February 25, 2008 Posted February 25, 2008 just had a thought as any of your fairing come lose Quote
Guest Posted February 25, 2008 Posted February 25, 2008 No... a bit more sinister than that..it really sounds like some one is hitting the frame with a metal bar...bang bang..it does not happen while the bike is stationery or while being taken up the revs while stationery, but as soon as you start moving bang..bang.. thanks for taking the time Quote
cyberwolf Posted February 25, 2008 Posted February 25, 2008 do you know where abouts it is coming from backend, front Quote
Guest Posted February 25, 2008 Posted February 25, 2008 Definitely lower engine mid to back round the foot pegs area Quote
cyberwolf Posted February 25, 2008 Posted February 25, 2008 Definitely lower engine mid to back round the foot pegs area have you check all blots and the shock i dont really know the be peeps on later that have more off a ide then me Quote
Guest Posted February 25, 2008 Posted February 25, 2008 yes thanks.....much appreciate the help... ... Quote
Guest Posted February 25, 2008 Posted February 25, 2008 I have had this in the past with a ZXR750.It took ages to find and was the pivot for the swingarm.It might be worth trying to see if the pin moves as there was no play detected but the bearing had seized.Let us know how you go on. Quote
Guest Posted February 25, 2008 Posted February 25, 2008 Makes sense......thanks.. Wierd one that!Will you let us know what it is/was when you've finally sussed it Quote
Guest Posted February 25, 2008 Posted February 25, 2008 yeah ..will post the cause as soon as I know it.....hopefully tonight.. The pivot does sound sensible...what i did not add was the bike stood still on it's side stand for approx. 3 months during the autumn last year..so seizure is a possibility ... Quote
nomad Posted February 25, 2008 Posted February 25, 2008 not sure if you have a centre stand but if you do is the retaining spring loose and the stand knocking? also check wheel bearings they can throw noise under the bike from the front wheel... Lastly is there anything under the seat or in the tool storage which is ratelling... Quote
Guest Posted February 25, 2008 Posted February 25, 2008 Thanks...had the center stand off and lubed at the weekend...springs are good and retaining the upright position. Wheel bearings APPEAR ok...not checked thoroughly but will have a look. .......,,this is a triumph were are talking about......under seat storage.....I could not even pack" something for the weekend sir"...in that thing..

Guest Posted February 25, 2008 Posted February 25, 2008 How've you found the Triumph generally Gordon I know where there's a nishe old sprint for sale near me...Dunno if I can afford it, but it looks nishe Quote
Guest Posted February 25, 2008 Posted February 25, 2008 Mine has been good.... no real problems..other than usual wear and tear...she's done 38k miles. I have rebuilt front end which made her a different bike totally, put uprated springs and reduced the oil weight, beleive it or not the back suspension is still good..ish... no rust on her and she kept outside all weathers. Some people say they don't handle very well, but i think that is due to being poorly serviced especially the front end suspension. If i had to i can keep up with most bikes through the twisties. Ground clearance can be a little bit of a problem but they are not a bike to go racing on. Mileage is keen..big tank 21litres or so often costs me over £20 to fill up, but i get 180/190 miles to the tank on motorway and 160 round the lanes. There are some good breakers on the web, sprintmanufacturing are excellent and Lynx motorcycles have never let me down. I paid £2000 4 years ago. I consider her an excellent bike for me. Insurance cover for me fully comp £60..can't remember who with..if needed will supply Quote
Stu Posted February 25, 2008 Posted February 25, 2008 does it accelarate smoothly ?if it judders in time with the banging it could be gearbox problem Quote
Guest Posted March 4, 2008 Posted March 4, 2008 any update on this--got me baffled --would of said swingarm as actual engine appeared ok while stood revving Quote
Guest Posted March 4, 2008 Posted March 4, 2008 all bearings checked out ok..........all linkages free and moving..looks like it's go to go to triumph.... Quote
Guest Posted March 12, 2008 Posted March 12, 2008 did you find the cause of the noise Gordon ?? Quote
Guest Posted March 12, 2008 Posted March 12, 2008 No. not yet..have not been in the uk for a couple of weeks. enjoying the cold of the Spanish mountains. Will get it into triumph when I get back and post the cause Quote
