Alright, that's a no to the higher pitch in that case.
Doesn't look like I'm going to get any of this stuff before the weekend now. I have a whole heap of new stuff that I'm dying to get on the bike, so the drivetrain stuff is going to have to wait I think.
If I can get the bike running this weekend I'll place an order for one of those anodised renthal rear sprockets, a 428 chain and a standard front sprocket. I'll probably come back and ask about chains then.
Here's hoping I can get a spark this weekend.
