It465 barrel on yz465
« on: April 03, 2019, 06:12:00 AM »
Hi guys

Is it ok for me to put a 1982 IT465 barrel with Wossner 2mm oversize on my 1980 YZ465? The piston is brand new and the bore has been done to suit so the barrel is effectively brand new in that sense. Just want to make sure it?ll be ok I guess so as the barrel is same shape, size and exhaust exit is the same too.

Cheers
Mark

I'm running a YZ 465 Cylinder on a combination of an 81 YZ 465 left side transmission case and 82 YZ 490 right transmission case... And running an IT 490 crankshaft... And 83+ YZ / IT clutch... And 1982 YZ 490 ignition... And a custom pipe from a 2000"s honda cr 250.. I bet just swapping a cylinder will be fine.. I believe the cdi box is the same between the IT and YZ... Should work...

Yes I guess it will work no probs. I have a yz piston in my IT so should all interchange. Sounds like you have a lot of different parts of different motors to your bike but if it?s working sweet then happy days. Thanks for messaging Dave.

yeah will work fine., there is an old thread on here that had barrel measurements.. the difference from hazy memory between the 4V6 and the 3R5 was something like 2mm in the top of the exhaust port in the sleeve.

I've got a YZ465H barrel on my spare IT465, and YZ465G IT465H and YZ490J barrels sitting on my shelf if I had to measure them to confirm.
