It only needs to clear the driven gear on the end of the alternator.  Just clip it off with a cutoff wheel in a die grinder and get it relatively flush. There is a reasonable amount of clearance behind the gear and you can easily check it visually. It's not necessary to go to all the trouble to set up a mill cutter.

Figured a quick update was in order. Not a lot of progress on the engine, but all the parts are in. And that pesky shaft/nub is no longer in the way.

Most of last weekend was spent at NJMP watching the super bikes play in the rain. Interestingly 3 of the last 4 MotoAmerica races in NJ were in the wet. The USCRA guys were also in attendance, and like last year It was fun watching them go round.

I did manage to find a little time between rain drops on Friday to put the final coat of clear on. Ended up going with white. I think it looks rather nice with the big Bridgestone markings.

The under lying color is your standard Rustoleum. With a top coat of USC 2K high gloss clear. Very impressed with how this went on. It’s a 2 part clear, you “pop” a button on the bottom of the can shake for 2 min, and spray. And it’s full proof - I hope.

Thought I was making such good progress over the last two weeks. The “nub” has been removed, everything is scrubbed clean and oiled up. All new seals, and even new head studs. Assembly was moving smoothly, then…

I striped out the cylinder head stud hole in the block. I’m going to try to open it up, and install a helicoil without stripping the engine down again. Otherwise it all comes apart, and gets resembled again.

Damn!  Yes, helicoils work for that, and it really shouldn't be hard to keep the chips out of the bottom end. I've done one or two over the years.

Whats that saying, use the right tool for the job?

After 7 un-successful attempts with the original “official” Helicoil kit. I ordered an e-z coil kit. First attempt, success! The e-z tool keeps the coil comprised as it threads into the hole. The helicoil tool does not have a way to keep compression on the coil. So it expands, and attempts to cross thread the hole.

So product recommendation. If you want to use a coil based thread prepare method. Get eh E-Z Coil kit.

To do it all over again, I would probably get a Time-Sert kit. I like the idea of having the top hat that time-sert provides. In the case of the coil, you need to install it slightly below the top of the hole. Not a bit deal in most cases, but the head stud is slightly narrower than the hole needed to install the coil. So the stud is going to be slightly shorter by a thread or two. Shouldn’t be an issue.

Now I can get back to building this engine.

Massacred Helicoils


Get this tool!


It makes this easy


And fixed

Managed to steal a couple hours over the weekend - double duty watching WSBK, and building an engine.

One of the nice surprises that came with the spares package is a packet of new SR clutch plates - Thanks Richard! It’s good to, because two of the plates that were in the bike were broken.

Assembly is going smooth, with everything seeming to fit where it should. Fingers crossed…
