Hi RR, just checked 2009 I started reading about you and this rigs exploits ,what a story and my god you've stuck at it, not forgetting some of the tough times to! Re the wrecked motor strange sometimes you know you just have to let it run its course ,the rebuild now will produce another superb motor and you'll decide which way to go. Good luck to you and thanks for all the interesting posts past and to come ,cheers Bob.
Thanks Bob, the forum has introduced me to people worldwide. have even lent vehicles to both a Brit and a German member, sent parts to Ireland and US and do enjoy sharing the journey with my fellow preunit twin enthusiasts. I decided the engine would stay largely stock. I got some 10.5's but found they have quite a gudgeon pin offset so tdc was a few mm down the bore and by that stage had resleeved assuming the same deck height, so couldnt machine more off. So I settled on some 9:1's much like the ones that came out, just std size. I am planning to scale back my racing the outfit but once the rig is race ready still do selective meetings and also get the solo up. Might even look at lending the rig out under supervision...
When I first built the racer I wondered how strong it would be, you hear such horror stories. I'm no engineer, just an IT guy who- has enjoyed fettling and pottering with old shit since he was a teenager. But in spite of my lack of expertise my engines have largely been able to take surprising abuse.
Getting all the aluminium debris out has/ is being a shocker. after about the 10th wash (every cleaning product I can think of) I rinsed the oil tank with PA10 to lock in any further debris.
But I have to repeat that I cannot praise this engine enough. Its tough and goes so well.
My original stock 54 RR rebuild has taken too long, case alignment issues and its all matching stock original. But its all happening, if its not right it doesnt go back together until it is.
But Bender my loyal sidecar is top of the queue right now.
