Hello

Thank you for checking out our website!

Majority of our stock are reproduction parts, but we now stock some Yamaha original parts too. The OEM number against each part is for reference and ease of use, each product has a description clearly indicating whether it is an original or a reproduction. We also have some parts that are from ARS Japan, though they are purchased in bulk and lack the Yamaha cetrified packaging. All Yamaha genuine parts have an image with the packaging on it as a proof of origin and will come originally packaged. We have now also grouped all original parts into a dedicated section, that is growing with demand sumorubber.com/yamaha-oem-parts

The chain pullers, that we have in stock are brand new reproductions and have only been available from this manufacturer for few months, so they will certainly be different to those you purchased a while ago. However, if you would like me to take any measurements to confirm the fitment, please let me know.

 

That would be great to have these reproduced, the decompression valve cover is also a part I can't seem to find too.

 
DT Tim, do you have the part number for the decompression valve cover? 

I think that Tim is referring to this part (see link).

Sorry, specific link won't paste. Part number is 275-12278-00.

Thanks. I'll keep an eye out for it on ebay!

s with all reproductions, we need one good quality (if not new) sample to use as a mould for the new parts, so if anyone comes across one of these or has one at home and is willing to volunteer for greater good, please let me know.

Hello Alistair,

I have just received the damper 214-11161-00 and as expected, it is very similar to one of the DTMX dampers in stock, however it is a conical shape with one end 2 mm smaller in diameter than the other. See pictures. I'll pass it onto our manufacturing team. It will take 6 months to add it to the stock. I'll keep the community posted. If you have any other suggestions for rubber parts, let me know!

Thank you for suggestions. I'm still looking for the decompression valve cover. So far no luck :'(

Gaps between the vertical fins is different by about 2mm between the 250 and 360. As model code 214 is for the DT1, presumably these ones fit the 250.

CMSNL show four as being required, but I'm not sure which of the fins they fit between!

Hello,
I checked several parts lists available online, and it seems that the 214 and 171 versions are interchangeable and there are 4 required for the RT2. If someone can confirm that they are indeed identical, it would be much appreciated. We could then list both part numbers against the 214 damper.
Many thanks!

Evening Jackie.

As per my previous post, I measured the gaps between the fins on my DT3 and RT2. The DT were approx 11.3mm and the RT were approx 9.3mm, so I would suggest dampers are not interchangeable. Maybe wait for others to confirm this, though.
