What size chain does a 1974 yamaha enduro 80 dirt bike take and where could I get one? Hi Adam,,, Those ol' 80's were very cool bikes and lots of fun---still are really. Here's a chain on Ebay you can "mail order" for about $20. Sounds like a good price to me. I dunno if You're familiar with getting stuff from Ebay,,,but it usually takes about a week http://cgi.ebay.com/ebaymotors/yamaha-gt... ................................. SIZE,,, There's 2 things to "Size".. 1)Actual LINK SIZE ,,,which is expressed as a sorta Code Number like "#40,,, #420,,,#428,,,#50,,#520,,#530"... and so on 2)The Total Length of the chain,,,which is measured in Number of Links Yours is SUPPOSED to BE #420 x 106 Links I say Supposed to be because as long as I been foolin' with chain,,,SIZING has always been hit-or-miss. I can't tell you how many times I've found even Factory Parts manuals WRONG. Or,,,sometimes a person has changed Sprocket sizes which requires a different length chain. There's a method of measuring/selling chain by-the-link. But somehow there's often some confusion over "What is a Link?",,,"Where do yo start measuring from??" "Pins,,or Plates??" It gets like an Old 3 Stooges Routine sometimes,,,LOL. Your BEST BET is always to remove your chain and take it to a bike shop for them to compare.....if you can do that. Most shops keep BULK chain in stock. Just a ROLL of Chain they cut to size,,and include a master link. Most times it's better quality chain and even Cheaper sometimes,,,cuz it's not Pre-Packaged For a Mfgr to sell to Dealers to Sell to YOU. Here's a Warning and a Tip: Make certain your Sprockets are in Good Shape. Bad Sprockets will wear out a New Chain in no time. And the New Chain will be hell on Worn Sprockets--they'll get Worser Faster. Same goes for an OLD CHAIN on New Sprockets. They "Fit and work" when mis-matched,,,but it always causes extreme rapid wear. They really Do have to all "Mesh" Correctly,,,just like 2 gears do. TIP: Your bike uses a #420 Chain. That Number describes some dimensions --- The size of the Rollers,, the "Pitch"which is the Distance between each Pin---sorta the Length of EACH individual Link,,, And the Overall WIDTH of the chain's links. A #428 Chain is SAME as a #420,,except it's a LITTLE WIDER. It's made to be used on Wider Sprockets,,,to withstand Higher Horsepower. Back in Your bike's day,,, All 100's and Smaller came with #420 chains & Sprockets,, and most all 125's ,175's,200's came with #428. You can "Upgrade" to a Wider,Stronger #428 "125 Chain" from your #420 by simply using the wider chain. Far as wear and tear,,,,a 428 is BULLETPROOF on an 80. Plus,,,they dont wear sprokets as bad,,,especially when riding a lot in dirt/mud/sand. Cuz the extra Width is better at "self-cleaning" and doesnt grind crap into the sprockets from fitting so snug on the SIDES of the sprocket. Beauty is,,,#428 is a Direct Fit,,No Modifications necessary,,,and usually doesnt Cost anymore. And because they are rated for Higher Power and Speed,,,even a CHEAP 428 is Better than a Good 420. So if you go to a shop and have them cut you a piece of Bulk Chain to match your existing one,,, Get 428 instead of the standard 420. Or you can count your links,,,and shop for a chain by Link/Length and in a #428 Size. Yours is SUPPOSED to be 106 Links. Count each SIDEPLATE as a Link,,whether it's an Inner Link or an Outer Plate. Each Open End is always an Inner Link w/ an open hole for the Master Link. That's Link #1,,Then between EACH Pin is a Link O=x=x=x=x=O O is Open end = is a link plate x is a PIN So,,O=x is #1 link,,x=x is #2,,Next x=x is #3 ,,Next x=x is 4th,,,and Last X=o is Link #5 O=x=x=x=x=O 1>2>3>4>5 Count Yours,,and Count it AGAIN,,LOL Should be 106 ,,If you have standard size sprockets. Get Same number of Links,,,but #428 Size Later Model YZ80 used #428 ,,,but Longer. VERY common and popular upgrade,,,even the MFGRS eventually began doing it. Just for the sake of saying..... You can get a Longer Chain,,,and "Cut it" to correct length yourself. A Good Chain Breaker is usually $15~20...but should last a lifetime. Or,,You can simply Grind the pin you need to remove,,and tap it out with a hammer and punch. It's EASY,,,,but Be CERTAIN you're cutting it in right spot. Or,,most anyplace that works on Bikes or even lawn equip will usually cut it for you for no charge. Only advantage of buying one "Too Long" is that You MIGHT find one on Ebay for a Super Deal that nobody's bidding on and snag it really Cheap. And you'll also have some Extra Links in case you ever wanna put on a Bigger Sprocket. ......................... Here's an EXCELLENT one on Ebay $18,,,and is the alleged "Right Size",,,106 Links Diamond Motorcycle/ATV Chain 428HD x 106 Links - NEW http://cgi.ebay.com/ebaymotors/diamond-m... If it was MY 80,,,that's what I'd put on it. Lube it once in a while and you'll Never wear it out or break it. Back when your 80 was made,,Diamond Chain was considered "Best Available" by everyone. And except for 1 or 2 exotic & rare chains that regular folks couldn't get,,or afford,,,Diamond really was easily BEST available. COUNT YOUR LINKS before You Buy anything! Make Double Sure. Hope that helps,,have Fun & Be Careful! I would buy a 120 link chain in a 420 size. 420 size chains are used on all smaller bikes now days. I would buy a 120 link chain, which will be too long, but you can cut the chain to the appropriate length. good luck..... Yeah...i'd go what with he said..heres a couple sites you could probably find it on.. www.motosport.com OR www.denniskirk.com |
