Hi, Kev,

a question. What is the insert in the water tube upper water pump. It's seems like a radiator. Is a commercial part, or you have done by yourself ??

Thank you. Ciao.[/quote]

I got them made up myself, just another XT Kev mod I did.

There's only one Kev!!! :occasion14:

You know me well Fran, I am always thinking of new things to do.

This past weekend KLR & myself sat down & worked out what needs to be done & how to make the worlds first +5mm stroker crankshaft for the XT660, just need a used XT660 crankshaft now. This reminds me of a few years back when I did the Raptor cylinder conversion, I get quiet excited about the unknown.

yup, this fix worked for me. no more rattle on startup. thanks :)

Almost a year later, the rattle is back.
Lucky it doesn't cost that much, but still ....:tear:

Only seen a few XT660's that have this rattle at start up & mainly 07/08 models.

Is it a problem if I placed the 'seat' (rubber on top of the ball) upside down?
I know it's silly, but I don't feel like take it down apart again..



Edit:
Never mind, fixed it today :)

does this rattle sound "clicky" or like "ticking" ?
