That was quick. "Good morning - I can assure you that the head has not been machines or used It was a brand new crate engine pull off It had not been used or machined in anyway shape or form They are all exactly the same as that one but DRR is often out of parts (like 90cc cylinders) so we handle the best way that we can so buy crate engines so that we have parts (not fun for us but only way to keep the parts out in the field sometimes) If your not content please use this link for a return returns.richcommerce.co/return/new?c=gforcepowersportsSent remotely from iPhone Gary Fallon | President" I guess I was corrected about it being used. To me, if it has been bolted on then it is used, but that is sort of a semantics battle and of little consequence. A little disappointing to get a dirty head and that's considered standard practice, but I'd rather have parts available than not. Now the issue is that I have to figure out if this can work. Maybe looks are deceiving and the chamber isn't as big as I thought. I can find that out with my burette. Can't be too accurate unfortunately, because how the squish band is cut will throw it off some. 0.004" is only 0.1mm so that's not really a big deal to have to cut to level before cutting to get a gap there. I was trying to keep as much of an o-ring groove on the outside as possible, just for fear that the ring may not be held in place well enough if too much is cut. 0.lmm shouldn't make or break me there. I'm just not gonna reply or take other action till I have a better idea of what I've got. If it can be dirty with markings from being bolted on, then me putting some colored water in the chamber should be of no consequence to anyone. What I find interesting is how it appears to be done. If I had to guess based on this, I'd say DRR must mod heads in house or have them modified from more generic castings. Makes me wonder what the compression is on these things and why they'd want to use a sub-50mm chamber on a 52mm... or is this a 50mm head that just gets used on the 52mm too? Do the DRR cylinders come up 0.004" higher in the center or do you just never get them to seal since they don't show a gasket other than the o-ring. Damn. Now I've got more questions than answers and I don't think Gary really wants to answer them. Oh boy... |

I had a recent run-in with a very popular vendor around these parts where I was very cordial and had to go back a forth with them regarding an issue and it turned out it was a error on their part, which they were trying to blame me for. Even called me a liar essentially. No worries, Ebay just gets a little more of my business now and I only deal with them when I have to. My point is they rectified the situation in the end, but never apologized for being so rude and implying I was trying to use deception to hustle them out of $10 (when I've spent near $1,000 within a span of months), but I'm still so salty and entitled that I take my business elsewhere when I can haha. I wish I was a little more level-headed, like yourself. I still get some really, really perverse pleasure out of teaching people a lesson... One thing that you may notice throughout my 100cc LC adventure is that I really don't have many choices. PFS quit selling most of the stuff that they had for them. Autotech355 did as well. I've dealt with some other sites that show up over the years and they can be hit or miss. Not many people have this stuff. They aren't even popular enough that I've had luck with eBay searches for used heads. The ones that I do find are the other style that wouldn't work on my cylinder. Much different experience than if I needed something more common like a Malossi, Polini, etc... or even AC 90cc parts. |

What a load of BS! Acting like he they did you a favor just by selling you a used part.

That’s not something I’ve ever given much thought to. 100cc LC parts do sound like a tall order. I get it now lol.

To me personally, if it's been bolted on to an engine, it's not new. Even if it's never been started. If this is common practice for them, it should state so in the description.

Realistically, nothing is hurt. I do believe what he says. Everything looks good, aside from the marks from install and leftover debris. I wouldn't think I'm the only person that has ever inquired about such a thing though. Personally, I'd think a simple note like : "Sometimes parts may be taken from new crate engines in order to meet demands and supply you with parts that may not otherwise be available at the time. These parts may show signs of installation and require mild cleanup. Please contact us if this is an issue." Then only crazed 90cc freaks like me would prob ever pay that much attention to the combustion chamber design, notice the 0.004" difference, measure the diameter, etc...
I'm still terribly curious if those DRR cylinders have a flat deck all the way across or not. I may have to ask whenever I figure out what I'm doing so it doesn't keep me awake at night. lol I didn't check anything today. I rode to bike week instead.

BTW, I'm not crazy right? I mean about the cylinder head. I know I am crazy in general.  Does it look more like a modified head than what would typically come from a factory to y'all too? |

H yeah. no new head should have anything stuck in the threads; OR orientation markings, OR
per your observation -
"Obviously a used head at first glance. Disappointed to get this, because it's so obvious that it was at least installed from any angle that you look at it. On the top side, you can see the "torque marks" that someone added for alignment with the nuts I assume. Then you can see that it has had cylinder nuts/washers and a spark plug installed. There's sealant in the threads for the temp sensor."
ALSO "What a load of BS! Acting like he they did you a favor just by selling you a used part."
I tend to agree with Old Geek that his response was ____________ fill in the blank; I do think his reply could have been a little less cursory and more friendly. Apparently he's not trying to win friends and influence customers.
You have every reason to be disappointed - and then some - so , no your not crazy.

If it wasn’t listed as a new take off then it’s a used part to me. Like you said there are no options for others so why else can you do besides send it back and be where you were. A better price would of been nice but...

There were '90cc'AC quad motors built with 50x45,wonder if some LC's were done that way too,,,That'd explain the chamber rework???

Yes it looks highly modified IMO. Crate engine my A$$. Looks like a motor built by a team, possibly a backup that never made it to the track? I bet the deck started out flat/even, before it was modded. I dont blame you if you keep it, it's likely better than nothing. |

Sorry to be so negative. I have had a few recent disappointments from Vendors you could normally trust and I am a bit peeved at them in general at the moment. I got autotech on Feebay has me blocked from bidding on their auctions because they want to deal direct rather than go through Feebay. I got another one sending krap parts, then making me pay return shipping to send their junk back. I got orders showing up missing big parts with no explanation, then I have to keep after them to get it right. Its one delay after another.

Is there an actual "brand new" head from somewhere else for the same price. Doesn't a new engine have to be ran for a certain amount of time to see if it functions properly? Or are they just pressure testing these fully built engines out the door? I guess it all depends on the person... I probably wouldn't get mad. Definitely disappointed that I paid for a perfectly brand new part that was supposed to show up shiny and sparkling. I'd say ask for a discount. There definitely getting a discount on a fully built engine by parting it out just to meet customer needs. I bet even if they did discount it there still making money off of the parted out products they sell. Nobody get into the scooter parts selling business to sell scooter parts at break even prices.

I'd be kinda surprised if they even get a leak test, but I don't claim to know a lot about how any factory works. I'm curious how DRR does things because they aren't the run of the mill Chinarelli and how the head that I got is modified vs standard 90cc stuff. So far, the only stuff I've found is the same price and kinda seems like it may be coming from the same place to me. There are more squared heads and some that are squared and have mounting bolts for the head to cylinder, but I think the o-ring wouldn't align with my outer sealing surface so that wouldn't work out too well. I really don't care abotu the used part so much. It's more a question of IF this even works, because I'm quickly running out of options. I gotta get out in the garage sometime today and cc this thing to see how bad it is. I wish they'd just make a Polini Sport/Corsa or similar cast iron/dual ring for the 90cc and none of this would be an issue. Unfortunately I'm in the minority here. Most people just don't care about a 90cc unless they're trying to build a race engine and the 70cc varieties cover it. BTW, stock DRR 90 crate engines sell from about $1300 to over $1800. I'm kinda stuck in a bubble with some ATV racers that prob buy these for young kids and tow them in enclosed trailers behind Platinum Edition F250s. Different world than I live in. These things are throw away parts in some of their worlds. www.gforcemx.com/collections/engine-complete/products/engine-complete?variant=19728570515549 |
