Had the following update from the owner, the bikes back together and well the following was an email sent to me, thought I'd share it:
Just wanted to say thanks again for all your input and moral support with the rebuild of that dropped rod
the rods I got of you are in the motor and I am totally confident they will last the distance (what ever distance it ends up doing) ...both rods looked in excellent nick but one looked slightly "fatter" in all dimensions , strange .... anyhow I took them cheekily up to post shop and put them on their scales ....wondering if there would be enough weight difference to cause a problem , but NO , they were within 2 grams of each other , the "fatter " one was actually lighter ... very strange .... suffice it to say I am delighted with those rods, so much better than the "next best" I was going to use .... im picking they are pretty low mileage.
Anyhow bike has done around 800 miles now , a bit of an issue , in fact quite an issue , with smoke .... I'm picking that the Johnson Engineering rings I used just simply weren't totally round ....it is GRADUALY bedding in and after plenty of fowled plugs settling down ok...
I wouldn't dare tell you how I "encouraged " them to bed in ....but it did involve isohexane and brasso .... yeah I know bush engineer right. Man that thing pulled some revs during the "encouragement process" ... if it didn't go bang then it isn't going to.
I know it is a comparative term but to me that silly old A10 with its excessive 6.5:1 compression really does go like shit off a stick, not a hint of bottom end noise!
gave it a new wiring loom and got charging system sorted ....... all good there...... sorted quite a few little issues while it was up on the platform.
