Thanks CarlosI would always de-magnetize steel engine parts, specially bearings, needles, rollers. It is also standard and recommended practice for high performance bearings used in Jet Turbine engines...FYI
To big deal to de-mag
Don't know why; the ProX rods we use and sell all come from Japan, my understanding is they are made at the same Factory the Honda OEM rods originated from. We also use Honda OEM Rods from old stock and some that are still available as new OEM.@acecarlos .
I'm being told by many enthusiasts all over the world not to rebuild my crank with the Japanese made PRO-X 1978-2001 CR250 connecting rod kit. I thought they were the best aftermarket option on the market.
So should I go with OEM rod and pieces or go with the NOS OEM 1983 CR250R crankshaft???

I wouldn’t put a lot of validity to what “everyone” has to say; unfortunately, a lot of advice given comes from hearsay, make your own decisions based on experience and sound judgement. That’s my approach…
As an FYI; I have rebuilt dozens and dozens of OEM & HR crankshafts using the ProX Rods, and never had one fail to date.
Nice....-)@acecarlos and @matuus

My NOS OEM '83 CR250R was shipped out this morning! Probably the last one in existence.
No more worries about rebuilding a wore out crank with a aftermarket rod kit and Loctite 680 on the journals to retain the pair of OEM main bearings.
Interesting Honda switched to the full circle tin can covered crank the following year in '84 when Yamaha retained the similar '83 Honda sculpted web TZ125 crank in 1995. A 125 engine putting out 44 bhp stock.
That's interesting. ThanksNice....-)
As far as Honda and Tin covered crankshafts, here is one I bet most don't know. Honda went to Tins for two reasons I was told back in 85-86. One is to stuff the cases, the other was to validate their IP. Honda had various Patents on 2 strokes, one included Tins. In order to add 'strength to their IP, they used Tins. This would keep others from being able to copy other aspects of their 2-stroke technology.
