Yamaha TRX850 Enthusiasts Forum

Question, i can buy this head cheap, i want to have it as spare either my trx or my tdm 3vd , would it fit and work on my tdm 3vd?

I can only think of swapping the cams if i would use it on my tdm anything else any catch i dont foresee?

Some of the earlier cylinder heads (XTZ750) and possibly TDM 3vd do not have the engine mounting lugs on the rear of the head. Some do but are not drilled and threaded.
The cam cover on earlier heads is also different as the heads have less cover fixing bolts, so you would need to check that and have the correct cover.
