Yamaha TRX850 Enthusiasts Forum

Hello all,

As i know that some people read also other forums and because i want every fan of the TRX (like me) to see it, i will post also some pictures of the evolution here, although i posted them in the supertwin850.de forum.

Suggestions, help, comments welcome.

Regards

Some more pictures of the exhaust headers.

Wow.

Do you also work on Toyota rally cars?

Do you also work on Toyota rally cars?

Hahahahaha.
I think the correct question is "Did you ever work on Toyota rally cars?", coz I'm pretty sure the entire team was sacked when they got banned.
It was a great car though.

My colleague Ignacio has finished another necessary piece.

This week we have made good progress.

I was at "Davol Tecnologic" with my friend Josep Oliva and Ignacio Santamaria (he makes the exhausts and other parts).

01) Josep had finished the valves and the new springs.
02) Also reworked the forks and added anchors for radial brakes.
03) He got the shaft.
03a) The cylinder head on the flow bench.
03b) Josep does the leak test.
03c) Ignacio and Josep just before the standard flow test.
03d) Josep with the Rotaflex in hand.
04) Standard inlet valves.
05) Reworked ports. You can see the lowered valve guides and the reworked ducts.
06) View from the other side, there is still some work to be done....
07) First test.

This is the first part of the process, but we can already see an improvement in flow and a different velocity distribution in the last part of the port.

There is still a lot to do, but we are progressing little by little.
