Andy,
We really appreciate your input. You have confirmed what we were already thinking and will just bite the bullet and get it repaired. It’s not worth the risk.
This will also assist us in our discussions with the person who sold us the cylinder. We bought the cylinder a few weeks back to keep us up and running as our front cylinder had a light seizure.
We didn’t have the opportunity to inspect it other than a few pictures being sent of the bore which looked okay and when asked, the seller advised that the bore looked to be in pretty good condition. (pretty damn good was his exact description)
We only spotted the crack when it arrived in the post and from my dealings with the person I genuinely don’t think they knew there was a problem with it. We’ve since went back to him with a very reasonable response to advise him of the crack and that we had reservations about using the cylinder. We suggested that we were prepared to send it back to him for a refund or alternatively, if he was willing to contribute to 50% of the repair costs this would also be an option. (50% would equate to around £100)
Although he was reasonably sympathetic in his response, he stated that we never asked if there were any cracks in the exhaust port bridge, he thinks we’re being over cautious, he’s not willing to offer a refund and his suggested contribution to the repair is £20. He said that if we have concerns about using it then we should sell it on to someone else but we would never consider doing that.
Anyway, enough of our tales of woe, we’ll just chalk it down to experience!
Onwards and upwards…I’ll PM you regards piston and rings as we’ll need to sort this out before sending it off for repair.hi
Thanks again!
Jamie
