update for you guys:It took off the screen pack and mesh filter and decided to try uni foam air filter which seems to be playing really nicely with the 3D printed slide. I'm using a 72 size jet in there which may be a size too big but my head temperature was getting up to a 370s with a 70 jet. No runaway idle issues from what I can tell so far but I didn't ride too long because this fuck
Actually that's probably a #9 isn't it
So i got my order from treats today. They sent me a #8 slide by mistake which is quite interesting because they don't have the #8 listed on their site. Wondering if I should keep it since they don't make them anymore
Referencing your other post Jay, im assuming you could not get past the run away idle problem no matter how many screens you removed from the pack, is that correct? With the information you provided me yesterday about air flow and the screen packs im thinking that i can possibly get the #6 i filed down to work with some airfilter tinkering or even the #7 or #9 that were making the clutch grab befo
Really appreciate this tom! Thank you. Ill keep you all updated gonna be busy the next few days with work and got some bad weather ahead so things are hold for now.
I know i have 3, possibly 4. Are you selling your casted slides? Definitely seems like its worth a try. I did go ahead and order the 3D printed one with the #6 from treats but ill to bet yours will operate better. Ive got venmo and zelle
Welp nevermind.... I guess I must have ruined the slide or something. I had it almost perfect and I'm just so pissed off right now. After filing it down I started 4 stroking again so I went And tried my jets all the way down to 58 so now I am bogging and then 4 strokeing. I am just at a loss I was so close just should left the damn thing alone. I am done for the day. I guess I'm just goi
Well it looks like #6 was the ticket. I thottle is much more responsive on the low end and no more 4 stroking Most importantly. Didn't want to use #6 because it didn't clear the venturi all the way but it's only a couple centimeters and I'll just have to grind down a little bit. Got a 65 in jet in there and my top speed is now 34 mph hoping maybe I can get another mile or 2 aft
In a side note, this is opposite to my previous issue where i had #2 slide and 60 jet the clutch would not engage untill a very high idle
So I've added the screen pack in between the air filter and the carb, put in the #7 slide, I've tried jets from 75 to 65 but I can't get the clutch to stop grabbing before it stalls. Scratching my head here Do I need to keep going lower on the jet?
The with the #9 the clutch catches before i can turn down the idle enough before stalling so im gonna give #7 a go
Hey tom, could you post a photo of that slide sids by side with a #1, I have a bunch of #1s so that'd be the side I'm most comfortable trying to modify
The o-ring was one of the first things i did before puting on the carb. As for my air filter i have a short compact one similar to thisi do have a screen pack im not using but i can easily pop that in behind the airfilter. Is the short filter okay? If not i might as well ditch it and grab a foam one as you said and if thats the case which would you recommend?As for the boost holes, which number s
That's good to know about I only assumed that the CDI was the only option for QT50s. What would the benefit of changing my timing be in this situation? Seems drastic at this point in time
Now this is some really good info to have. Im assuming since i have a 15:15 i dont have to modify my slides to much or even use the shorter ones, is that correct? Or would the shorter slides lean out the mixture more than than longer one a the 15:15? Bernoulli's principle or something? I failed chemistry
QT50s timing cannot be adjusted unless i get a $300 CDI kit from treats. As for compression, the 60cc kit was put on around late August and crankshaft seals were replaced as well so i dont think Compression should be the problem either. I recently went form a bp4hs plug to a bp6hs
Most people understand the concept of jetting. To me it seems these carbs arent popular as upgrades cause theres not to many threads about tuning the low end so they get overlooked or skipped . Im willing to put in the time to figure out how to get it running optimally. When i post on reddit it seems no one is aware of how slide effects performance which makes sense because when they come stock on
Ill give that a shot tomorrow, got 12hr shift today. But i was thinking the same thing about the jet but i kept going down so it wouldn't 4 stroke at lower temps. Now that i think about it, it makes sense my engine wont hold the heat at 1/4 thottle if the slide is letting in too much gas to begin with but when frustrated you dont think logically
Ive been relying on my temp gauge because it helps me indicate if i will 4 stroke when i open the thottle all the way. Less than 320° i will 4 stroke but over 320° its usually fine however 320° is not my usual operating temp. Ill warm her up nice and hot before riding and blast off but as i ride at slower speeds in the duratation of my ride the temp goes down and i 4 stroke.
Its a trail tech from treats with the spark plug washer
So i dont think SHA carbs are a favorite on kitted QT50s but thats what im rocking with and was hoping to find others similar setup that can tell me what they have going on. On the entire internet this site is the only place that even talks about slide tuning for these carbs that ive found and they are old ass threads with nothing to do with QT50sYz60 kitMLM side bleedDellorto 15:15 carbCone mesh
