I am installing mine Tuesday night, I will let you know how mine goes. I hadn't heard about any issues like that pumashine, have you called them?

This is the billet version. OldschoolR Doug let me borrow it while his bike was being rebuilt. He told me about the problem cause it happened to him. You could be out in the middle of nowhere and have this happen. something about the carb being level. Sounds like a crock of chit to me. I have heard this in my reading about these carbs also. So I'm supposed to fix this? Are you freaking serious. They can't build a $750 carb that does not work without flaws like this? Freaking ridiculous

[JasonB]

Contact Steve Liz or Corey. I'm pretty sure the issue that carb is having is with the coating on the tip valve balls, there's two little valves and the first coue runs of the billet carbs had issues with the anti tip valves balls sticking. They changed the coating and the problem stopped. Call apt, I have heard nothing but great things from them about handling issues like these. Either way sorry your billet carb isn't what you expected. I will let you guys know how my cast works

So I hooked up the smart carb turned the petcock on and gas poring out the air filter. I would guess the cylinder and bottom end are full also. You cannot level the carb as it is already over sized.  Doug told me about the problem before I put it on. Thought I would wait and see. Doesn't really matter if it works as it won't start!

Was the choke pulled up for initial fueling per the tag above?

After turning the petcock on and before kicking over the choke is pulled.

Doug never had any problems til that LS trip is what he told me. He had to turn off his gas constantly whenever we quit riding to take a break. His R did sound and run awesome tho. Personally I'm not sold on them yet, but I'm cheap and don't go ride all different places across the country so my jetting stays pretty much the same. They sound great in theory, but I'll wait. I'd actually be more interested in one for a dirt bike, but I don't like the idea of it pouring fuel out(or worse-into my motor). A lot of guys have been using Lectrons on their bikes, but those have problems too. For now I'm sticking with what works- my already jetted carb(s). I plan on just buying a newKeihin 38mm carb for my 85cr500 that I'm SLOWLY rebuilding. Yes jetting that won't be fun(or to hard either), but it can't be any less frustrating than some of the horror stories I've heard off.  

It seems like some of you are having luck with the smartcarb and I'm glad you are. I do believe that there is a lot of potential in this product, but I'm def gonna wait and prob pass too.

I think its just that we are not familiar with them yet. Could pull a kiehen apart and put back together in less than 5 minutes. I guess I am just afraid of ruining a $750 item. :lol: By the end of the week I will be know as pumasmart rebuild guru.

Thanks for the heads up Dennis, now I don't feel like such a retard. I thought Doug said it only happened to him once.

I'm hopeful that this product works out. We have wild fluctuations in temperature here in MN.

I don't blame you for being afraid to work on someone else's stuff like his carb Tony(especially since it's kinda irreplaceable now that the cast ones are out). IDK enough abt one to want to mess with one. I'll take the 5 min kiehen carb myself too as I'm used to them and already have a ton of jets and such for them.

[rablack21]

I don't blame you for not wanting to mess with something that belongs to another person. It sounds like there might be an underlying issue going on with the carb that shouldn't be happening. I'm sure that if Doug contacted Corey at APT, I'm sure they would take care of it. They have been nothing but helpful an courteous when I have called. That sounds like what needs to take place. There is clearly something going on there. There were a few things different on the first generation billet version that aren't like the newer billets and cast versions. Sounds like Doug really needs to make a call and see what's up. I'm eager to see how Jason's reaction is when he gets to try his in the next day or two.

[Quinnlt4]

From what I understand the first gen billets are different. When I ordered my cast there was the first gen on sale for $625 but you could also order the newer ones at the 750 still.  Hopefully they corrected the issue.

[rablack21]

I am all but sure that the first gen billet versions didn't have the tip over valve like my cast version has. That pertains to those floating balls someone mentioned.

Got mine in Monday
Feels good to finally get my hands on this thing. They also sent me a needle to try it out on my cr 500 too

[rablack21]

Cool deal, Allison#51. Let us know what you think once you have had time to run it a bit.

[JasonB]

let us know how it runs on your cr500. I had nothing but trouble trying to run it on my cr500 motor, WILL NOT start and run normally unless the carb is set around 50 clicks which makes the damn thing rich as hell. Frustrated me to no end out at little sahara last week. I was going to send it back to APT but will try it on my 310 first. I hope to try it on the 310 next week sometime, but i seriously cant put it into words how frustrated i was with this carb last week when it came time to try and ride the damn bike.
