Rotor wobble

I just fitted a Power dynamo to my H1B but I noticed that the rotor doesn't run quite true has anyone came across this before or does it point to my crank being bent at the end, if so can it be repaired or does it require a new crank or a rebuild with a new end section what would this cost, or is there an acceptable runoff. Another but reluctant way is to refit the old points as the rotor is smaller and probably would be OK, any input appreciated.

I'd be concerned about any wobble, the end is a weak point at best and they are quite prone to shearing off at the best of times :?

Ive checked the shaft and the taper on my crankshaft is off, so I will need to remove the crankshaft, also I had to send back my stator and rotor from my Power dynamo to be repaired as it caused damage by hitting, The previous owner told me he had the crank overhauled but going by the build of the rest of the bike I am a bit dubious the engine is the only part I have not stripped down and rebuilt, so when I remove the crank I will decide whether to just have the end balance weight and taper replaced or whether to get a complete overhaul for piece of mind, I have sent a message to Garry Clarke and I also spoke to a company called SEP who said they could replace the broken part with a second hand part or do me a full rebuild on my crank has anyone else had any similar experiences and is there anyone recommended in Scotland to do cranks.

I will speak to Gary in a few weeks I'm away to work and he is overseas also I will remove the shaft when I get home and make a judgement I will also need to pay for the replacement parts for my powerdynamo.

I have spoke to Garry and he will be doing my crank as it transpires the crank must have been bent when I bought the bike tis was a bike that I was told that Gary had done the crank and Neil had built the engine , Neil has never heard of the guy or recognises my bike and I'm sure Gary doesn't supply bent cranks the rest of the bike was shoddily put together before I stripped it down and it looks as if the crank has never been out so it will need seals and bearings as well as a new end section, I don't know how some people can sleep at night bullshitting fellow bikers with lies, at least when I get the crank back from Garry and put the engine together myself I know it will be right.

Oh well at the end of the day I was never going to be happy until I had the engine in a million bits I never had any confidence in it I rebuilt the rest of the bike over last winter the first time I went out on the bike when I bought it I ripped the back tyre due to the extra inch of the bolts sticking through the back mudguard which fell offs the secondyime I went out due to no washers on the grommets that hold it on , I suspected the guy was no engineer when I found nylon nuts on the exhaust flanges, getting my crank done should cure my pre ignition problems if the seals have never been done and the timing would have never been right on the points with the bent crank, it shouldn't take me long to overhaul the engine there doesn't look to be much to it , I'm sure it will be pretty similar to my Gt750 without the hassle of fitting one piece barrels, is there anything particular I should check on the H1 when I have the engine stripped.

Sent crank to Garry Clarke who replaced the bent bit and done a full overhaul with new rods, also powerdynamo fixed and sold me the parts I needed at a good price, bike is all together and running nice thanks to Garry who was also very helpful with advice and done a lovely job of the crank top bloke thanks.
