Hey guys, what is the clearance the rod bearings need? I did the grinding on the kfx cases to make room for the 840 pistons, split them to clean everything out.... got a headache from all the carb cleaner fluid and PB blaster...LOL

Anyway, it is ready to reassemble. I have 4 brand new yellow rod bearings and I want to try those to see where I stand, may need to go up or down a size or maybe they are perfect.

Does anyone have the clearance specs?

Thanks!

I'd just hate to be wrong, I'm almost 99.9% sure that's the range that's given in the manual. Sorry can't say definitively

you using plastigage

I do know it's a little better to be on the looser end of the range, than to be to tight

That center shaft is the heavy style one with the big spring on it,the one without the spring is much lighter.

The other ones have to be about a pound lighter.
