My favorite in the first video is the rideable luggage. Too cool

Today I met the Monster Jog guy and he borrowed me this pipe here for testing purposes. The pipe comes with 6x3g roller weights and 2000rpm clutch springs, which tells me they want you to go very high on the rpms to reach the pipes power band? Kinda looks like a Burial clone.

Looks like a Gianelli Metal! But 3g rollers? Phew man thats going into Yasuni c20 territory and this pipe is certainly no c20. I would start off with 5gr see what happens. During acceleration you will hit the pipe's powerband, don't worry. It'll only take a bit longer. But don't go super light right away dude, you wanna determine the pipe's powerband first....and later tune to that.

Lucass2TThx as always very appreciated. No worries I don't intend to use 3g rollers and stiffer clutch springs. I'm gonna put the pipe and see how it behaves with the current setup I have and then I'll just go from there. This is anyway just for testing not a long term thing, the pipe is not mine. It will give me good insights as to what my power output could be when putting a higher/better pipe then what I currently have. I am sure there is a little bit more power somewhere in there inside my BBK and carb I just need to get it out.

Yesterday my scoot started to bog down between 3/4 to WOT. So I went from 38/90 to 38/92. Today on the way to work again it started to bog down when I crank it open and release repeatedly. I think I might have gotten the whole MJ thing wrong. Since I raised the MJ from 90 to 92 I reached max rpms of 9400! I will try to go higher on the MJ till I reach the point where it sputters (rich) again. The low and mid range are nice and crisp so I'll keep that as is for now. So after all I might have been driving a bit too lean and therefore not reaching good rpms? When I'm running on WOT it sounds like "BWAAAAAAA...." kinda hollow sound.

If it's bogging then it's lean. I'm wondering though, why change your pilot when you change your main?

I don't change the pilot only the MJ.

tsimi I have same carb I bought the AU262 atomizer ans the 2T bushing but when I installed it I was running way to rich. I went down fro a 107mj to a 90 and still didn't rung right so I put the 4T stuff back in. how drastic was your jetting and or needle change? I have stock needle and slide for the Dellorto 19mm PHBG whatever domes with Malossi carb ki.

I have stock needle and slide for the Dellorto 19mm PHBG whatever domes with Malossi carb ki. Yeah, same here. When I bought the carb I had this inside: - AN atomizer and bushing - #30 slide - W9 needle (2nd position from top) - 45 pilot jet - 75 main jet - 4gr. float I use the stock airbox without the snorkel. I then started tuning with - AN atomizer and bushing - #30 slide - W9 needle (2nd position from top) - 38 pilot jet - 95 main jet - 4gr. float This setting was very good at WOT (wide open throttle) but too rich at the start. I knew that a 38 pilot jet was not good with the AN stuff. Then I got my AU (2stroke) stuff and pilot jets 30, 35 and 37 So I followed corrosions recommended setting which was (corrosion is a member in this and other forum.) - AU262 atomizer and C bushing - #40 slide - W7 needle (2nd position from top) - 38 pilot jet (corrosion recommend #40 with additional holes in airbox which I don't have. That's why #38) - 90 main jet - 4gr. float With that setting I had a crisper power at low- & mid-range but it always felt kinda limited at WOT. I never did a thorough trial and error after installing the AU stuff. But I knew that I couldn't drive with the previous setting (PJ38/MJ95). A #95 MJ was just too rich but now I am at #92 and it still feels kinda lean around WOT. I still got Jets like #93, #94 and anything above to test. I also have to double check my airbox if there is any air leak because it is kinda odd to be suddenly running lean when it was OK before. I also was thinking about putting back the AN stuff but before I do that I want to do more testing. You are sure right to say that with the AN stuff carb tuning was more easy then now with the AU stuff. The only thing I can tell you is that with the AU stuff I feel that there is more power and torque compare to the AN stuff.

Sort of off topic, but I still can't get my head around the fact we both have "sport" 70cc kits (mine being a 68cc with the shorter Suzuki stroke), stock airboxs, yet your running in the low-mid 90mj range while I'm thinking mine is still a bit lean at WOT with a 108mj!

Raizer We do have a similar BBK setup but I think there is a difference between a 17.5mm PHVA and a 19mm PHBG Dello carb. My Jog had stock a #68 MJ now I have something between 90-95 ? huge step up considering that I have a stock airbox without snorkel. But then again with my stock 16mm carb I had a 96 MJ installed. Bigger carb size is not equal larger MJ it could be the exact opposite, a smaller carb might need a larger jet to accomplish what a larger carb could do with a smaller jet. Make sense? I am no expert and this is a mere guess so don't take my word for it. And one more thing, in this topic there is no off-topic, everything/anything can be discussed here, except for 4T stuff.

I am running Malossi BBK 72CC sport but I have the 19m PHBG Dellorto right now with 4T atomizer and bushing running stock idle jet at 42 and main at 107 I have a modified derestricted airbox with OEM filter out and two layers of COARSE UNI red filter element in place, snorkel restriction out, and TWO 1" holes drilled in airbox with UNI prefilter inserts in
