Yamaha TRX850 Enthusiasts Forum

Very quickly, people who have done this - what do you need to do and how hard is it? Would like to keep Rex head and oil tank

Cheers

Barrels, pistons, rods of the 900.. rest should be mods here and there I believe

cheapest option would be to buy my setup and have all the benefits of fuel injection along with it

Sorted - thanks Ian

Does there need to be material removed from the engine crank cases so the bottom of the 900 sleeves can fit into the crankcase???

No

not if you use the full tdm setup.

So the trx with the new HT leads was much stronger, to the tune of 10mph at the end of park straight!

Almost makes me think I should have just hung onto the tdm setup and mildy tuned it. But I have bought the MT09 setup now so I am going with it.

I also know of an 850 with 900 barrel and the crankcase mouth wasn't opened up
