Oh boy did she get an upgrade. I swapped the 21mm PWK for the matching carb but 26mm then added the Polini Bell mouth to it. There's zero space for any filter and that is the thinnest stack I could find, still barely touches the frame. Installed a 110 main and 46 idle jet. Needle with clip all the way to the top and she is fast. Really fast!   |

Maybe you can go to a rear facing carb setup. The clear bowl looks sick but it may leak if you use it for the long haul. Love how this thing is coming along

Well I was about 1.5 miles from home and started losing power, but not a lot. Came to a stop and it idled down like normal... kinda. Idled down and died. Would not start back up. I fear a broken or cracker reed but idk, I walker her home and ended up installing new tires on Sonja my daily driver (the blue Stella).
Time for some damn tacos.

I'd want to figure out some sort of filter for a street scoot. Maybe just a sock that can fit over. 2Ts have enough things to cause wear without ingesting whatever debris gets near enough their mouths. Kinda looks like you'd open up a lot of options if you could get the carb/intake angled downward just a bit. Rear facing would likely open it up to fit a pod filter, but you will have to swap out the engine mount. It is the preferred setup for power junkies AFAIK because the charge can have the most direct shot.

Yeah, I'd love to swap to premix and install this 360° Polini intake but I'd have to drill and tap my carb for a vacuum fitting for the petcock. That's definitely on the to-do list. Maybe even the Polini reed block of the wallet allows.

No I just need to drain it and pull it to match up a manual one. #lazy #professionalcrastinator |

So I realized I could just use the stock reeds, DOH! haha I pulled the intake off and found this:   Totally blew out the reed... I remember hearing a noise like flapping plastic (like a tiny fairing starting flapping against the body or something) right before the loss of power - which was the reed getting chewed up. BUT, I didn't get a picture, when I removed the block the little "spring" that helps seal the pedal against the base was broken! It was late when I noticed it sitting on my table, saw the metal on one side but not the other. It's a good piece of metal too... so now I'm shocked that the piston and crank are still healthy and not all scored up! I've been driving it ever since the swap to the stock reeds and they don't like going over 10k too much. I get little sputters and hiccups which I can only assume is flutter at high rpms. I'm gonna bite the bullet and get the Polini reed block. I like the larger mouths and pedals for more flow. Now to find a manual fuel valve, then I can use the Polini 360° intake and switch to premix. Oh, I did the "zip tie trick" to the oil pump - I zip tied it wide open to flow like all the oil all the time. It pumps to the intake, not the carb, so it shouldn't run any more lean, right? Just more oil to foul the plug hehe. Then it's the stroker crank, porting/trenching and some taller gears... but that's another project for another day. |

Here's the broken stuff:  Flew home on my lunch break, pulled the stock reed block out and installed the Polini reed block. It comes with a thick and thin set of pedals, I think the thin set is on there now. I LOST PERFORMANCE. Like, really weird, but WOT at 50mph actually makes me lose speed, 2/3 throttle and the power/speed comes back. With the SSP-G reeds and stock, I could just hold WOT and get to 52 sitting up easily. I think it's the thinner reeds letting them flutter, but I'm not sure. The actual inlet seems smaller than the SSP-G. I took pictures but just realized they came out WAY too dark and you can't see anything. I shouldn't need the stuffers as the carb is 26mm, intake is 28mm and it just dumps right to the reeds, I'd use the stuffers if it was the stock carb/intake with the upgraded reeds. I'm gonna swap the pedals out after work and see if that helps... kinda strange as I thought the Polini would be better all around. |

Don't a lot of the high end intakes use dual stage reeds? Thicker by the cylinder, thinner in the back, to avoid flutter? Or am I just remembering something that never happened? |

Hey you know what's crazy is I thought exactly that... Why not use both? But no I've never heard of that scenario really. Just got the idea from Boyesen dual stage... Why not make the v block a dual stage itself? Haha maybe I'll try just for fun. |

So I measured the reeds from Polini. Blue print is .3mm and green print is .4mm. I installed the thicker and it's night and day difference. Like this is the fastest I've gone yet! Buried the speedo but didn't have the GPS on so I don't know true speeds.
Take off is a little less snappy, which was to be expected... But once the high RPMs kick in it just keeps pulling! 5.2g setup had me around 9500 so I need to go lighter and raise them just a hair. What I do like with the current setup is at 53ish the belt maxes travel and I'm at 9600 and that leaves me a lot of room to go (was holding 10,600 and even got to 11,000 a few times). Wait... Anyone know what a stock crank can handle?? Haha I can't wait to get the stroker and really time this baby right. As of now, she's running GREAT.

So I tried the 2 different reeds at the same time. Thicker one to the cylinder side and thin one to the crank side. It has a better idle (like with both thin pedals) and feels way better on the low end. Feels snappier all around really. I'm gonna try a good long ride like this and see how I like it.
