Please help does anyone know where i can buy a complete r/h chain assembled engine for my yz 125

without googling it, i'd say they don't exist (standard from yamaha that is, dunno bout homemade jobs)

why do you want one? what's wrong with standard left-hand drive

myne is rh assembled it is the way that they were made in the 1982 to 85 trouble is they are very hard to find and myne has a hole out the side and a munched gear box

IT200 from that era is the right hand chain, don't know if the bits are interchangable though

chains and sprokets are symetrical...so why do you specifically need right hand ones??

i think his bike would perform better if both the front and rear sprocket were on the same side of the bike

LOL. You could try eBay, they have lot of old bike parts, but I'd say you will have a hard time finding the bits.

good luck with that, i suspect unless a wrecker did have the parts your only option is to give it to an engineer to remake the gearbox... or change the rear assembly; maybe flip the wheel over and modify the swing arm to hold the brake on the rhs

sounds like an "interesting" restoration, good luck

how hard is that to do though?

Some of the early eighties Yamaha models had the drive from the gearbox on the right hand side

Get in touch with the kart people - a lot of YZ125's of that era went into karts.There were plenty of rolling chassis missus engines around I know that....
