lincs brian Posted July 15, 2006 Share Posted July 15, 2006 i have a trx 850 1999- because it had done a fair mileage and the valves were worn , i chose to buy a top end off ebay, this was said to be a trx barrel pistons/head- anyway it turns out that the head is different- it had different cams, and the rocker cover from my trx doesnt match the new head- we have swapped cams over- and all is well except i need to know what model 850 twin the new head came from- the seller on ebay was told it was trx- but can anyone suggest which model i need to source a rocker cover from ? i do know the trx engine was a slightly tuned version of the earlier tdm 850- yet at barton bike night last wednesday -i saw a tdm and the rocker cover looked the same fitting as my trx item ? any ideas -? at yhe front of the trx cover there are 4 bolt holes- the head i now have seems only to need two at the front ? HELP !......... cheers- brian Link to comment Share on other sites More sharing options...
