Hey Folks,
Hoping for info from folks who have either an Xs400 and 750, one or both.
A fellow in Australia will be receiving a SOFCA soon for his XS750 that he's fixing up for some racing. I know the 750 uses the same filter and filter cup as the 1100, but a different filter cup "bolt"...Yamaha calls it the bypass valve assembly in the fiche!
I would expect that Yamaha would have used the same machining tools for making the bolt hole threads for both models since they use the same cups, but the bolts may just be different lengths??
I know the size/thread of the 11 is 20mm x 1.5mm pitch, and would expect the 750 to be the same, and a simple testing of the 1100 bolt test threading it into the 750 hole would suffice!
This Aussie also has a 400, and would like to get a SOFCA for it as well. But what I don't know is whether it uses the same size/thread pitch for the filter bolt as the 1100. The parts fiche shows different numbers for the cup and filter element, as well as the bolt/bypass, but it has the same WASHER, which would be sized to allow the same size/diameter 20mm bolt as the 1100.
Has anybody who has a 400 ever tried their 1100 filter bolt in the 400 bolt hole, or can confirm that it's the same size/thread pitch??
Also, if someone will be doing an oil/filter change on their 400 anytime in the near future, if they could take some photos of the engine case where the cup fits, and measure the diameter of the filter cup mating surface, both inner and outer, and also if any parts protrude away from the engine case inside the filter cup area above the cup mating surface, that would be very helpful in me being able to adapt my machining of the 1100 SOFCA so that it could fit the 400! A big thanks in advance for any/all info on this!
T.C.
