(Sorry for the double post to WR & YZ side, but given the popularity of the Ty Davis tank I thought a lot of people would be interested.) I was looking at the GYT-R site from the rally guard mounts post and saw this tank: From the description and picture it looks to be based on, or identical to, the IMS Ty Davis tank. I remember a few guys (Vincent WR400 for one) had problems with the petcock mounting threads. I wonder who is making this product for Yamaha? Are they just selling the same part? For $230 (dry break included, blue or opaque) I think someone here should try this thing out (I already have an IMS).
