Opinions on the xpw

[Landscape2956]

I saw a xpw posted for sale. Claimed to be ported, this was the picture of the cylinder he posted with the ad. I’m no genius but I don’t see much work done here.... thoughts?

I’ll move this over to the chainsaw pages. It’ll get more traffic there.

Looks like the squish band is cut / sanded and the ports have definitely been worked. Whether it will run well is anyone’s guess. Doesn’t look terrible to me, but not perfect.

I think it has a fair amount of work done to it, band has been cut and base ona lathe for sure. Lowers have had the shroud lowered like a 390, and all the other ports have definitely been reworked as well, I would say they have done a few cylinders for sure.

By the looks of your signature your opinion may be a bit biased

I’d be a bit leary of the rough exhaust port bevel. Lots of edges there to snag a ring on.

You can call it what you want but if that's not considered ported I am not sure what is? What else is there left to do to a cylinder? Not sure who ported it, not my work but it's clean and I would not be ashamed of it. Those uppers and the rest have some time in them

 

[dustinwilt68]

I believe what you think you DNT see is called tallent, it's hard to make ports look clean like factory, when in reality they have all been changed, hold up a Oem cylinder next to it and you will clearly see the amount of work it takes.

Edge just looks like it isn't beveled yet to me. Still has marker on the cylinder wall, I think it's unfinished yet in this pic.

I didn’t say there’s anything wrong with the port work. All I said was that edge looked a little bit sharp. I don’t know if they got sanded or not, which is why I said something. And the guy was asking for opinions. If I didn’t know what I was looking for, and came to a place like this looking for advice, I’d be pissed if nobody said anything and I snagged a ring on the exhaust port

That cylinder has several hours in it. I like the xpw jug for the extra cc and have done a dozen or more and whoever did it spent some time to get the ports that smooth and symmetrical looking on the transfers.

I think those bevels are enough to not snag a ring. It’s not a big one to ease the rings back in but I would run it without a second thought. All the rings I snagged were in transfers from being greedy with width.

Here's a picture of one just after it's been decked, before porting has begun. To give an idea of how much work goes into an xpw cylinder.

I agree. I thought the port work looked pretty good, myself. The only thing I was commenting on was what appears to be jagged edges on the ex roof and floor. But maybe it’s just the pic being fuzzy or maybe it wasn’t done yet. Who knows

Well for those who are intrested thays one of mine and i put alot of time into the xpw allare done the same way the band has band cut never sanded i dont sand bands the bevels were done after the pix i sent those as i did the cylinder so it all port edges got broke really good. I hope this helps the folks that are worried about it i tested it about a tank worth of fuel and the saw ran good.

Look at the blue ink in the cylinder

Guess the cat is out of the bag.

Questioning whether the cylinder has been touched at all is one of the greatest compliments one can be paid when it comes to porting a cylinder.

That’s nice work and even more remarkable now that it’s clear that it isn’t even finished in the pics.

Meh, I saw a guy out west that's taking money for port work say the other day that he's skeptical of the real need to chamfer port edges.

Thank you Doc

Here are some pics of a brand new XPW cylinder I will be porting for a customer, I know how much time it takes to get a cylinder to look like what Mike has done, I think the xpw cylinder is one of the hardest to get right and I have to agree with Doc, when people think your work is stock looking, that's an accomplishment. Hope these pics help.

That’s what I was looking for. Instead of everyone getting into pissing match. Thanks for posting that picture.
