With 120 miles up now it's time for a bit of fettling. The bike runs OK generally, but surging is an issue, and the battery is going flat after about 3 days, so two issues to be sorted.

Surging first. I have adjusted the idle screws to 3/4 turn out, and backed the idle adjuster off until it almost stalls. The rev counter isn't moving off the stop with the revs this low so I can't tell you what the revs are! Still surging, but if I leave the choke on it runs great, no surging at all, and sounds crisper all round, so it seems to be running lean generally. Time to check the float heights methinks.

I'll have to check out the charging circuits at the weekend, clearly something is wrong there, it's the second time the battery has drained now. Fortunately it starts first kick.

Phil, just a thought on the surging issue. I am no means an expert but also had the same problem after my rebuild. Tried everything as you do, but i took waterbuffalo's advice on his previous post about retarding the timing slightly.
Although not totally rectified, its much better.!!!!!!!!!

Cheers. Yes, I saw that advice and might try it once I'm sure all the carb settings are as they should be. To retard the ignition the back plate would be turned anti-clockwise, is that right?

I will some time soon go through the pile of invoices I have accumulated, which literally is now 2 inches thick, and tot up just how much this whole thing has cost. I think I'll just enjoy ownership for a while first though :P .
I knew it was a mistake, but I did it.








£12,096.





:o :o :o :o :o :o :o :o


There are probably a few cash purchases I missed, but that covers all I have receipts for and the few cash purchases I can remember. It doesn't include the purchase price of the bike.

Just imagine how much on top of that the labour charge would be if you hadn't done the work yourself......well worth the cost i must say. A beutiful bike!

@barney1 - yes, that's true, I didn't tot up all the hours spent but it would be well into the 100s and would add a few thou to the cost.
