Ok I know I you guys are saying what is a 650 Yami doing on are site. Well I'm sure there may be a few who can answer this. Take a look at the picture. I have two engines. One was locked up and after pulling it apart I found a lead plug? had worked loose and hit the rod. There are two plugs. I think they were for balancing when they cut the gear for the electric start. The 72 was the first year for the starter and I think they just used the cranks from the 71 and older. Does anyone know the purpose of this plug. Is it a problem waiting to happen on my other crank. I can get a few thous movement fron the same plugs on my good crank.

As soon as I can get this beast back together I can start on the 75 Z1900B

The lead 'blob' is usually just for balancing the crank......

Bin it....

Impressive set of bike you got there....

That's what I thought also. I was just surprised to see it come out like that.Just makes me wonder about the other crank.

Had the same happen to me old RD350 many years ago. Went to pub had a few beers, came to ride home and bike locked up, lead weight fell out of crank.....rebuild time

Ok who would know how to correct the problem as long as I got the crank out.

Have a go yerself....

Just prepare the crank & melt the lead, whack it in & hey presto

If it don't work, then you can start phoning/Googling...

This bloke did a really good job of welding and balancing my Z1000-H crank way back in 82. The fact that he's still in business after all these years speaks volumes.
