[twinrock]

hey guys well after buying 2 dts to make one good one for a fun reliable paddock basher..its worked out great..im so happy that i want to build another one with the spares i have left over..now the engine i have left is pretty wasted..im wondering is there other engines i can be on the look out for which will either bolt in..or go close with lil mods...stuff id be lookin at would be it175 dt200(watercooled) dt250/400..any help would be great thanks..and if anyone have any of these engines to sell thanks

YZ125 until 1980.
DT125 (all).
DT175 (all).
DT100 (all, I think. Definitely the ones with the cross-over pipe).
IT125 (all).
IT175 until 1980.

YT125/175 engines might fit, but pull start and auto clutch and stuff means you probably don't want one anyhow.

Watch out for the LT1/AT1/CT1/AG motors with the very different lower engine mounting point - it hangs a lot lower and stands out like dog's balls if you know to look for it.

The later YZ125 and IT175s have the chain on the right.
The later-still YZ125s (1986 and later) and DT200s are a different motor again, and don't fit.
Not sure about the DT200Ns (single radiator, red shroud), but I doubt they'll bolt in - and they're water cooled anyhow.

nathan, can only presume your encyclopaedic knowledge of what can fit in where on what yama-thing results from years of trying to stuff different bits in yourself....drawing from your massive pool of parts out in the yard.  necessity is the mother of invention, right?

I wouldn't call my knowledge encyclopedic... But yes, having a big pile of shit and the desire to make things work without spending money certainly gives you the answers to questions you haven't even thought of...
