Hope it goes back together Ok.....   -------------- NEVER EAT ANYTHING BIGGER THAN YOUR HEAD.... Back to top

I have 3 LC cranks and they are all suffering the same problems - rooted big end journals maybe this is the answer although Yambits do replacement webs for the LC. I watched my mate strip my crank down and it was quite interesting. The problems are two fold firstly the excessive endfloat on the rods causes the edge of the big end cage to gouge into the journal. secondly if stood for any length of time the condensation in there tracks along the needles and causes corrosion to the bearing surface. So, if you plan leaving your bike for any great length of time fill the crankcase with old oil ! -------------- "The only thing worse than being talked about is not being talked about...." oscar Wilde Back to top

Can't remember if the early LC cranks are the same as YPVS ones, but if so, it would probably work out as cheap (or cheaper) to order a new Banshee crank from the US. I think we paid about 150/160 quid for a spanking new one for Martins NSR-D350 . Cheers Wb -------------- A garage overflowing with old stinkers... Back to top

Some awkward welding and machining required to make them fit apparently -------------- "The only thing worse than being talked about is not being talked about...." oscar Wilde Back to top

My problem in a nutshell !!      But it wasn't my fault though Guv'ner !! She has been on long runs regularly & covered 2,000 kms in the 5 & 1/2 months I've had 'er. !!   I'm trying to sort out photos of the damage to post on here. I'll get there eventually !!  (I'm FAR from being a pooter genious !!) -------------- Just when I'm about to make ends meet, someone moves the ends !! Back to top
