Re: andrews cam set for UL

It's probably old inventory parts because you can only find Sifton replica nowadays(in fact v-twin mfg with sifton label). I heard Andrews used to sell UL cams with slightly hotter intake cam profiles long time ago. Depending on the lift and the duration you can use them in a stock motor. But super hot cam requires some engine work in order to work right. Try to search panic papers on this suject, google victory library tech papers and also kns kustom hotter UL cams.

The UL cams are not V-Twin Mfg......they add the Sifton brand, but they are manufactured in Europe by the same manufacturer who makes the WL, WLDR and WR cams for over a decade now.

Re: andrews cam set for UL

I recently got the last set of stock replacement cams (for at least six months) for U models from Andrews. The ramps do appear to be more abrupt, but I think the lift is the same. The cams are very nice and run well together dry fit with new bushings. The only problem I had with them was the sizing on the inside journals, at .684 they were .002 under oem. I normal use the .6875 standard ream, but in the case I had to use an adjustable. Fortunately, the bushings were small enough on the ID to clean up at the proper clearance. Just something to consider if you are using a set of Andrews cams. If you try to use them as replacements without changing out the case bushings you will run very loose on the inside. Outside journals on 3+4 were correctly sized at .686.

Kurt, sorry my mistake, 45parts depot have them fabricated in Europe and v-twin mfg resells them with sifton label, right? I have a set for my bike and they are perfect. regards

No no, Samwel from Holland has them made and distributes them.

V-Twin does have some good things, just as long as it's from someone else.....lol

Re: andrews cam set for UL

I've seen the Andrews cam set now available from W&W cycles (item no.64-198) marked as 'new stuff'. The comments there are that they're 'mainly' the same as stock (mainly???) and the cam profile has been computer optimized. I hope to get some more accurate information regarding lift and timing - or has anybody already checked this?

Re: andrews cam set for UL

Got some information from W&W cycles: shaft diameter for case bushing is 0.6840" only (same as amklyde noted :roll: ) - can't understand why they made the shaft smaller than OEM...
cover side: cam 1: 0.7815", 2: 1.1235", 3&4: 0.6860"; valve lift 0.375"; duration 212deg @0.053 tappet lift.

Re: andrews cam set for UL

It is doubtful they will scrap all the cam sets so I guess the solution to the journals is to make you own bushings.

Re: andrews cam set for UL

As a manufacturer of racing parts for vintage motorcycles, I find it very hard to understand how a company can knowingly put on the market parts that they know do not fit correctly.
What kind of business ethics is that.
Unfortuanteluy that is what we have to accept from some of the major manufacturers of repop parts.

I alerted a major USA vintage hardware manufacturer when their latest offerings were drastically undersized.

The reply was: "We gotta sell these first".

Yes, Chris,

And these days they fit.
(Beware of steel offerings on ebay from another source, as they are tragic.)
