There is a .002" difference. That is an extremely small difference, but enough, that over time can allow the wrist pin slide past the clip and make contact with the cylinder wall.

Let me expound on this a little.

Yes the clip is slightly smaller in diameter, but it is not the only difference. The cir-clip groove in the Wiseco piston is also larger to allow the proper fitment of their larger cir-clip. When the Yamaha clip is used it sinks much deeper into the larger groove of the Wiseco piston.

Then the taper on the end of the wrist pin will work against the Yamaha clip causing it to go deeper in the groove and the wrist pin comes out an rubs on the cylinder.

The two cir-clip are not interchangeable. I am glad it came up in Fred and my conversation the other day, if not the result of the two photos I sent to him would have been devastating and dangerous.

Wow that would really suck. To have all your work take a crap. Over a tiny piece of wire. Really sucks, that you were just going to be able to go into big-time kookaloo... Oh nope, got to tare it back down.

Back to the hugger. The silver does look out of place..but man white looks soo good....
I have to resist. :diablo:

Looks great Fred. I have to disagree with Dan though. I think the hugger looks good in silver. It matches the swing arm, frame and chain guard and does not detract from the good looking white paint.  Dave
A pistol is like a parachute, if you need one and don't have one you will never need one again.

I only have one hugger, so I need to have it a color that works for both sets of bodywork. Silver seems to work ok. I have been toying with some ideas on modifying and shortening it a bit and the a two tone respray in Silver with a black chain guard area

That really is rotten luck Fred, I feel for you. Having to strip a 'just built' engine a few times over the years I know how heart breaking it is.
Are you going to put new rings in?

I spoke with Wiseco and I was told. With only 500 miles on the rings, that they are ok to reinstall. I was instructed to use a green scotch brite pad in soapy water to lightly scrub the cylinder walls. Once dry, lightly coat the cylinder walls with mineral based engine oil and reassemble.

The wrist pin clip has been replaced with the correct Wiseco clip. No damage to the cylinder wall. The engine is apart and waiting for new gaskets for reassembly.

How do the plugs look?


All 4 look the same. Had a difficult time getting the electrodes in focus.

Got the engine back together. should be ready for start up later this evening. My clicker torque wrench crapped out on me, had to break out the old school dial indicating torque wrench.

The only thing left is to install the smoked tail light and smoked rear signals. I am still waiting on a bracket.

Hey, just installed the same kit on my 84. I was wondering how reliability has been so far... while i am looking forward to having more power, a majority of time will be spent hauling the wife around.

Great write-up
Jason....

aviationfred

I currently have about 2600 miles on the rebuild and it is running great. I did a 634 mile ride Wednesday without  hiccup.
