Taffy can you confirm is this pin is yours?
If not, how looks yours?
This from the link below will be good for me?

I picked up my crank today.
This is the pro x rod in a 470 crank. A very reputable engine builder put it together. The crank pin was too long and the oil holes would not line up if the pin was pushed to stick out on the stator side. I told him to make sure the oil holes lined up.
This is the oil side the pin sticks out on this side. He ground the edge off the pin.
At this point I haven't tried the counterbalance on it or anything. If it won't work, I think I'll use the inner race as a spacer and go without the cb.
Edit : the cb won't workf like this so my options are to grind off the end of the pin or go without the counterbalance. I'm leaning towards the latter. I think I will do the weighing and see what it comes out at with the 380 piston.

the link you found is the right one if purchasing.
just to be clear hacker, that is NOT my rod kit in your photo and I think I made that 1000000% clear in my last post. I don't do bodge jobs.
all these pins should be supplied 60.0mm long.
all 650 kits circa 2001-2003 come with a 60mm pin AND a 61mm pin to this day yet I have never found the Husaberg that needs a 61mm pin. mind you, I don't exactly study these things....
as said before, you must make sure the oil feed lines up. we had a little trench machined costing me 70gbp + VAT at 20%.
it was so expensive that I decided to add nothing....how could I, even just VAT takes that to 84gbp.
as for that abortion you have KFS, it is simple, press it all apart again, have 4mm milled off the end of the pin. get the engineer to press the cap in about 1.5-2mm.
now I know that that isn't 4mm but the cap is 2mm in from the edge and can be pressed in. by the time he takes 4mm off the grinder will just start touching the top of the cap.
make sure the inside of the pin is fully washed out.
agian check the oil feed alignment.
suddenly my rod kits at 170gbp don't look too bad for value do they!

you can see here a quaint little trench has been machined just as Taffy has described then someone has ground out a section with a grinder costing 30c plus VAT to make sure the holes line up .. nothing wrong with that at all .. great idea in fact.
unfortunately it does look like someone with a large diam grinder has also elongated the little trench too far toward the center of the pin .. you can see where the edge of the crank web was from the mark on the pin and the extra grinding goes too far ... IMHO resulting in lack of oil pressure to the big end.
so its probably one of taffys kits that someone tried to fix with a grinder
orangeberg hasn't had any of his rod kits fail, id be shopping there

it would seem that I may have supplied a regular kit to whoever and that they have then found the problem of the oil feed and tried to do the extra work themselves OK? the engineering work to the end is at least similar to how we would do it but of course dozens of people could draw the saem simple solution to doing shortening the pin.
yes I have pins with the gutter in them but as I said they cost me a lot of money.
I hope this now clears this up?

we pulled the rod off two 400s recently that are genuine rods, the bikes are from 2001-2003. they have the 18mm little end bushes in them as well. more proof as little or nothing else had the 18mm little end in the 22mm eye.
the code on the rod is '151' and it is 119mm centres.
so does that beg the question....what did have 120mm centres? or was '151' the rod type and used for both lengths? I've certainly seen '151' on all the OEM 400 and 470 rods I've pulled out.
the old pre 2001s had 120mm centres so maybe someone mixed them up?
who knows for sure that they have had a rod with 120mm centres?

Eric? ned?
do you know which 499s and 501s had which con rod?
I'm guessing that the long stroke 501 from 1989-1993 had 125mm centres. (H210 030 01)
the 501 then went shorter stroke from/to 1994-2000 and had 120mm centres? (H210 075 01)
I know that all the 350 and 400 had 120mm centres also. (H210 029 01) but they have a different part number to the 501 rod?
this will most likely be the same rod but with a 20mm little end for the 501s and an 18mm little end for the 350/400. essentially the same rod though.
they did a 499 for a year (1991) but getting the centre centre on them will be hard. (H210 035 01)
I know that they removed the base gasket from 1994 so the camchain would fit. so that can't really be mucked about with. shortened a little perhaps, that is all?
Eric
can you send me a PDF of that parts book from 1991?
I remember the piston to head clearance on some of these being large at something like 2mm plus? any comments? anyone heard from Geoff (Coronaberg) in recent years?
thanks

I have no idea on the con rod fitment.
E-mailed you the parts book.
On my 97 600 there is no base gasket. The cam chain is a very tight fit and if a base gasket were to be used you could not put the cam chain together.
Yes there is definitely about a 2mm gap from the piston to head at TDC.

cheers for that. years ago when I did a few of these early engines they just came to me in a box and a few would have been MX bikes and the owners are notorious for knowing nothing of what they really have....not even the CC half the time!

Further to a chat this morning with Melvyn Spree the UK importers right hand man in the 90s, the following is what was fitted:
the long stroke 501 from 1989-1993 had 125mm centres (H210 030 01).
the 501 then went shorter stroke from/to 1994-2000 and had 120mm centres (H210 075 01).
Melvyn says that all the 350s and 400s also had 125mm centres! (H210 029 01) and with the 501 having 120mm centres that explains the different part number to the 501 rod.
they did a 499 for a year (1991) but getting the centre centre on them will be hard. (H210 035 01)
all I have are the records of two 350 rods. one says 126mm centres and the other says 125mm centres. the inside of the rod was just 37mm meaning that the needle rollers were 3.5mm and not the usual commercial 4mm inside a 38mm hole in the rod. he said that a lot of the early rods had this set up.
makes you wonder if the hardness inside the rod would be enough to machine from 37mm to 38mm when one has gone west? I doubt it though as the hardening is usually down to thou's
