Hey everybody been a while since i've been here. Need some help with my vin. I have a '77 kz1000 ltd. I cant find anywhere to decode my frame and engine numbers. If anyone can help me it would be greatly appreciated. My frame
number is KZT00B-501004 Engine number is KZT00AE010584

Here ya go. Both engine and frame are '77. Check this site for verification.

Good luck,

As you probably know, all the early 1015 LTD models were assembled in Nebraska...this is evident in the frame number, which has a leading '5' in the numerical portion of the VIN...means it was assembled in Nebraska...bikes assembled in Japan start with '0'. The sixth letter in the frame VIN is 'B' which means LTD model. The motor VIN series for early 1015 models was shared for A, B, and C series models so all these will have motor VIN's with the same alpha-numeric prefix...'E' means engine.

Thanks, appreciate the info. Will be posting some pics of my bike real soon.
