Fritte Started a new thread Want to buy: Gear 3rd pinion for YZ465 -81
2/25/2025 2:42pm Hey guys! My complete engine rebuild project took an abrupt turn! I got the crank case halves back from TIG welding and just when I’m about mounting the shafts I found a problem with the third gear. So now Im desperately looking for another one in a really good condition! It’s the third gear pinion with p/n 3R5-17131-02. I have...

2/11/2025 11:08am For the electrical system on this bike, I’m not sure how to proceed. The old stator plate can still work, the coils are not broken. There’s an extra coil on this one, for the lights. But when it comes to the old CDI box and the old ignition coil together, I don’t know how to test them, and they really...

Fun project! I built and raced a 81 YZ465 in our vintage harescramble series. It was a fun bike but the dead engine starts use to kill me. LOL Find a YZ490 clutch basket setup and kick starter shaft. The clutch plates are still available and the main gear is one piece with the kick starter gear, the older ones would spin as it was just a press fit. The kick starter shaft has a welded on stop, the older ones would crack and spin. You can weld that case up if you don't want to find a new one...

Robert Fish on Facebook (US) makes billet clutch baskets for the 465. I believe you have to machine or drill the rivets out, similar to using a Hinson basket on a newer bike then you can use your clutch gear.

If you can't find OEM parts, try Tom at DC Plastics in Michigan. They have been involved in vintage dirt bikes for many years. If they don't have your part they can most likely tell you where you can get it. Very helpful and nice people

1/30/2025 2:05pm Guys, are there any web sites I can find out more about where my bike is sold new, and what color it had from the beginning via my vin number? I figured it out like this Sold in USA - black and yellow Sold in Europe - white with red seat and red decals on tank But I’ve seen YZ465...

If you are looking for an OEM pipe, you will have to be patient. If you don't care about an aftermarket, you can try DG, PFR... or the australian Geof Morris. In Europe, as I said, vmxservice imports DG, or you can also contact some "handmade" manufacturer like JSV. The finish and the fitting of the DG is not the best, but the performance is very good.

1/29/2025 6:42pm Last2stroke, I definitely will! 😁 I found an exhaust on eBay! But it was for a 84-90 YZ490. https://www.ebay.com/itm/196932980999?_skw=yz490+exhaust&itmmeta=01JJTH… The part number for this was 40T-1461000 The part number for my bike 4V4-1461000 It’s only the three first digits. Will this be a perfect fit or that is absolutely not a good idea to try?

1/29/2025 4:44pm Thank you 🙏🏻 I need the primary gear for the big outer gear on the basket, the small inner one go to the kick idler gear! Time to find these parts! 😅

1/29/2025 5:04pm 450exc115, are you sure the one unit-basket needs to be 84 or newer? Can you if you have the ability, get me this 84 basket part number so I know what to look for? Or if you may know anybody selling this part? Very interesting with the cylinder head modification. But why? You say ping, or knock. Why would the...

1/29/2025 3:36pm I understand. So if I go for YZ490 -82 clutch, I’ll need the primary gear straight cut as well, and what more, a different kick shaft assembly with straight teeth there also? What positive purposes do I get from mounting 490 clutch, changed main gear and a different kick shaft assembly? Is it worth it, or I should just go...

1/29/2025 12:01pm Oh, this led me to a lot of new question as the newbie I am! 😅 You say the main gear is one piece with the kick starter gear, I don’t get it. Isn’t the main gear the little gear on the backside of the clutch basket? 🤔 I tried looking at exploded pictures but I couldn’t figure it out...

1/29/2025 11:30am Thank you for the tip! That exhaust looks perfect! 😁 Yes, that makes everything so fun. The bike is a YZ, vin nr is matching 4v4, and unique in this context. Today this would be impossible in Sweden, but since it was once registered, it’s still in the system. I have all papers from the Swedish traffic agency as well.

1/29/2025 12:43pm Thank you! But what clutch basket is the correct one for the YZ465? What’s the specific difference between angled or straight cut gears? Do both of them work? Thank you for your good information! I certainly need it

1/28/2025 6:25pm Thank you once again 🙏🏻 I’m very grateful! But you said the yz250 basket will fit yz465… I can notice thinner/smaller fins on the 250 compared to the 465. I guess my 465 lamell and metal plates don’t fit in a 250 basket? Shouldn’t this be a problem with torque etc?

1/28/2025 6:19pm Hey guys I bought a YZ465 -81 from a friend a couple of years ago, as a restoration project. I just started to take the engine apart and I found a lot of problems. Former owner told me the cylinder head was “planed” (don’t know the English word - Material was taken of the height of the cylinder head for...

1/28/2025 5:31pm Wow! You made my day! Thank you!! I bought the cylinder head, the kick idler gear and sent a message to the kick shaft seller. The exhaust was perfect, but that one will have to wait for next month salary 😃 Pistons will be great, they seemed available. Next thing is having the cylinder bore measured. The thing I need...

Have you tried CMNSl.com in Holland for the parts? They have NOS parts for many Japanese bikes and are near you. Keep us posted on the build, Peter
