In the 1st pic the hole seems off-centre. On the second pic it seems that the tap is crooked towards the arm at the shank side.

If the square of the shank is not already ¼” or just under, use a grinder to take material off all four sides and then use a ¼” socket driver extension. You can get a cheap one and grind the OD if you need to.

Put the extension on the tap and use a tap handle or even a wrench on the ¼” male side.


When specifying inserts (at work) I only use helicoils for occasional use. For higher service I rather use Time Serts for repairs. Higher cost, but reliable in the long run. Then there are E-Z lok, great as an OEM choice, but they need more material to tap a larger thread.

Good luck.

Just sent a PM at the ODSC with Garmin tracks from 2005 with some advice on how to follow it. If nothing else, it shows the beginning and end of some trails. Look at them on google maps and see if you find them useful.

Enjoy the south!

As I’m finding out the Helicoil taps aren’t “standard” sizes, I don’t believe a “long tap” exists for it.

I don’t have a welder but my buddy does…might have to take a trip to see him.

I just set the tap in the hole for picture purposed, I had begun tapping it yet hence why the tap appears to be cattywampus. The flat side of the tap is extremely close to the swing arm, I doubt grinding and then shaving down an extension would give me the clearance I need.

Thanks everyone for their input. I’m going to try welding the extension on to the tap. I'll let you know how it works out.

Don't do that, just throw it in the chop saw and cut the tap in half, grind some new flat spots into it until a 12 point socket fits, it'll be in the area where the axle goes then and a socket will clear.

Wham, bam, thank you ma'am, all done.

I tried a new way...

I bought some of the 3M flat black vinyl that they sell to sticker a whole car with for advertising. It has sun protection and everything in it already and I got plenty off eBay for cheap! It's tougher that paint and requires very little to get ready to apply - unlike the paint.

My understanding is that Bob didn't use the HRC race piston as it came ever. I think Johnny said the bike tended to come out from underneath him... But they did sometimes use the HRC piston milled to use Chevron or Pemex Premium in some high desert races. I have one of the HRC pistons milled and all the instructions from the shop.

Beautiful bike. I'm thinking of doing the black baja fender paint. Krylon fusion good?

I second hearing this as well. I think there were different combinations used at different locations, but I know not everyone looked kindly upon the increased compression due to poor fuel options. I'd be curious to find out what the real seat of the pants difference is, obviously I would take anything JC said as pretty much Gods word... I'm guessing i'd compare myself closer to Helen Keller's riding ability, than JC's
