winter project.....

Perfectly `safe`. Often motors are hung in spine frames with minimal engine mounting. The TRX frame is a very rigid design, the motor isn`t required to beef it up acting as a stressed member.
When the motor`s bolted in at the rear up to that cast alloy `H` section it keeps everything nice and rigid. I reckon one mount up by the head would be fine and dandy.

would that be safe?

I would prefer to have a lug welded onto the head if possible.

As said, i´m using the TRX head and other parts and using flatslides etc...I would want to have that lug also!

As safe as it is, I think in the interests of my OCD I think I will look into getting a lug welded onto there just like the other side.

Not sure how feasible that will be as its right near the head gasket. Dont really want anything warping there.

so wont that take you back down to an 850 then?

Nah, only the head so i can use the FCR´s etc...not cylinders/pistons. Have sourced a set of high comp wiseco´s as well

[coxylaad]

so are you using the 850 cams too?

[Killerwhale]

Yes, Tornado top effect cams.

[coxylaad]

well, I think I will be utilizing the TDM900 mounting points and adding some frame drop outs to hook them up.

Ive bben giving it some thought ( nice to meet you today by the way ) ........ the Trx 850 head is the way to go .......... you will be able to get a bit of porting done too whlst the heads off

[coxylaad]

the tdm900 throttle bodies wont mount to the TRX 850 head. so I exchange one problem for another!

Right you are, if one don´t own a pair of FCR´s i guess it´s better to go for injection!

[Mincehead]

Look up Quan-time`s posts and threads, he`s actually bored throttle bodies out to 41mm if I remember correctly. The thread you want also shows his flow bench and silicon mouldings of the head / inlet and exhaust tracts too.
I`m good to you lot:

This way you`ll have the advantages of FCR41`s with the injection system. For anything related to quality information about tuning TRX`s Quan`s posts are the ones to look up.

Good stuff that, although thats a lot of graft there for I am not sure what gain I would get.

If it released 110+bhp from the engine and retains its midrange punch I would be interested, but I worry you are just going to push the power further up the rev range and lose the midrange, which is the character of the engine to me.

I would like to have a genuine 100bhp engine with big mid range towque mind
