How to complicate a simple task!
I'll use a fencing maul to use as an "anvil" and use a generic drift to secure the rivets. I only need to use the bike for a couple of hundred miles following TPS reset and then its off the road. I'll be buying a new DID set with an oversize rear sprocket ready for next year
Its kinda strange but all this "hassle" is what I missed when I had the CBR
