YPVS box 250 TZR 2MA / 500 rd mod

#1 Post by solex27 » Thu Mar 29, 2007 5:22 pm

Hello,

I 'm new on this forum. Very interesting forum but sometime a bit difficult for me to understand all explanations!
My problem:
I've just bought a TZR YPVS box supposed to be a 2MA version. But now I think that is not one. The ref part is 34X-85841-00.
I can't test it because my 500rd is not running (engine is opened to be rebuilt and tuned by myself)
Who can help me to know what model is?

Thanks

Franck

It may have come off a 2MA mind because I understand that some of the 2MA boys put 34X boxes on - was supposed to make them better - not sure about this a friend who is a real 34X fan got fed up with being asked if he wanted to sell his spare YPVS boxes by the TRZ boys way back.

So whilst it is not a 2MA part - it MAY have come off a 2MA.

yep , that s very possible

the advantage using the TZR box is that it opens @7500 rpm while the RD5 @6500 rpm
i heard that some RD250-350 boxes do the same
