ULH CYLINDERS

Does anyone have any personal experience with the ULH Cylinder set being sold by V-Twin? Part number 49-1386 . The ad states country of origin is USA . I am interested in who the manufacturer is. I was under the impression that Tedds cylinders were of the India sort. Thanks

The first set of cylinders TEDD offered years ago were india cast -- and it was hit or miss on quality. Some folks had ZERO issues and some had multiple issues. My sample pool is only about 8 folks -- so let's not pretend I'm sharing "real" information.

Anyways, the issues I was made aware of were as follows:
1) RAPID wear of rings and the cylinder (as in 5K mile ring jobs and 10K mile hone/rebore; which is WAY less than stock components).
2) Port misalingments -- basically hard ledges jutting out under the seat area which point to core shift during casting. You'll find these on some BTSV cylinders from HD, but not as pronounced. The AM cylinders still work -- but you basically mask the air flow right under the valve seat. Correcting it can be done -- but for $1000 bucks you really don't want to be spending a lot of time reworking things that shouldn't suck to begin with.
3) Cylinder distortion under fastener stress -- as in if you fit the pistons tight you'd see a classic figure 8 on the thrust surfaces showing the high and low spots from the distortion. Whilst distortion isn't uncommon on flatheads, it shouldn't be so pronounced on brand new cylinders. It points to a lack of seasoning the castings and/or machining them unstressed.


I was recently informed the current TEDD cylinders are not the same and are of better quality. However I've no way to substantiate that claim and don't really know.

Finally, country of origin is not necessarily what you think.

Logically you'd think origin means "where it is from." However, origin = manufacture -- not necessarily where the components/materials are from.

Current standards allow for raw materials from overseas to be finished in the US and labeled as US made products if they are substantially and materially changed in the process.

In other words, the cylinders can be cast anywhere -- if they are finish machined in the US that constitutes a material change that is sufficient to call their country of origin US. In fact, the country of origin for the iron may be different from the country that cast them which may be different from the country that finishes them. Welcome to the global economy.

Damn you Globalization!!!! Thanks for the input. I will try and call them today but i doubt the lady on the phone can provide with the details. It doesn't hurt to ask.

If i have to buy a set of cylinders anyway is there any advantage to using UL cylinders instead of ULH? I using a set on VT cycle Aluminium heads from Sweden. Any chances that the 74" will run cooler? Maybe kickstart easier with the lower compression? Meaning less volume in the same size head. This bike will be a solo cruiser. No side car.

I do not have any knowledge of the quality of Tedds cylinders, but I have a set of ACF cylinders and with what I now know about them and the cost, I would spend the extra $ for FHP Sweden cylinders.
