Yamaha TRX850 Enthusiasts Forum

hey people what do you think of these? the guy says they were ment for a 900ss but they look like they would fit the trx to me?? he also said he was going to put them on his trx track bike, so maybe some work has been done?
how much work is it to fit the tps to them??? ...............so many questions, but they ant cheep, but not a bad price if they can be fitted without to much hassle.
o and one last thing, is there anything specific i should now or ask...........wheew

The FCR39s are good. Not as good as 41s but still good.
You may need longer spigots (connection tubes) to fit them to a trx if they were off a Ducati, but these are available from Allens performance in the uk.
Also you will need to bin the airbox and buy some pod foam filters.
If they are for a ducati, they may not have a tps connection, but you can bypass the trx tps using the mod I figured out (use search) which also gives 3-5 more bhp.
Go for it!

The TPS mounting plates are fairly cheap and can be fitted to ANY FCR`s, along with a longer spindle to actuate the TPS, Allens would get them for you or email Sudco in the states:

Allens FCR39 and 41 kits for the TRX come retrofitted with them from new.
