Three hours after pumping it up to 6psi today it was still just over 4psi.
I reckon that'll do. |

Your pressure testing is legendary. I just wait 10 minutes. Need to up my game.
I would like to say its hard to believe that Malossi reed block but it just isn't. A lot of parts now are a bit rough. |

Remarkable find really.
Ur motors are air tight enough to float with helium. Curious tho - the hole appeared to be round - as if bored. What do u make of the almost perfect circle ? Did that just punch out? |

Think I'm gonna need some help from the brains trust here.
I put a px lusso driveset in on the latest rebuild. Since then I've been really struggling to select gears. I've tried my liztor selector, then a used and crusty PX style one out of a box in the garage, then a shiny new one. Tonight the shiny new one went on. Was stiff at first, but it shifted, and went into all gears. I put some greaseon it and went for a spin. It was good at first - selected all gears and went up and down. I started to feel good about it and found some gaps in traffic to get it on the pipe. All good and wickedly fun. Next I headed to the freeway. Just after dark and pretty busy, but I got it into a gap, pushed it through the gears on the pipe, and was happily winding past 100 klicks when I could get a gap. then I jumped off the freeway, looped back on, and headed back into town (less traffic that way) Heading down the on ramp, I switch into "like you stole it" mode, and wanted to hit 4th really on the pipe. Clutch in, twist to 4th, nope. Massive resistance. Hmm, now I'm joing the freeway coasting on the clutch, rather than accellerating into my gap. Nasty. Rev, hold 3rd, jump off at the off ramp. From there on, all the way home,I only had 1st and second, and occasionally, if I twisted like I was going to break the cable, 3rd. I checked the cables, nothings caught, I loosened them slightly in case they were too tight, and I adjusted the clutch up and down. Weird. 1, neutral 2 and sometimes 3. Any thoughts on what I might have done? |

Any thoughts on what I might have done? Did the cruciform back off the threads a smidge? Checked the tiny tapered pin that's located in the selector box arm? Lusso driveset is EFL, correct? Could it be possible that you accidentally installed pre and post Lusso gears on the same stack? Newer selector boxes aren't the best of quality. Maybe that could be a problem as well? Some foreign object fell into your headset, causing the shift handle to not rotate forwards? Frayed gear selector cable causing a fiction point somewhere in your cable? The pinch bolts at the selector box are too tall, and are fouling out against the selector box cover? |

Life has been a little busy.
Went out and figured it out today. I'd already played with the selector box. And the cables. And the clutch. And the selector rod. And boroscoped the cruciform. Nada. I took the selector box off the cables completely, and the problem remained. Must be headset or cables. So I pulled out the headlight and speedo, and I looked hard in the headset. The cables ran free, but the selctor disk could concieveably foul on the inner edge of the headset (it's a px style disk in a Super headset). So I dremelled it. No good. I then thought I had it - the new disk has a new clip, maybe it's sticking. So I trimmed the excess of the ends. Better, but still sticking. Then I had a bloody good look at the tube itself. There was a big fracture, and a twist in the tube, and it was fouling on the clutch cable.. Getting it out was a chore. [/img] Problem solved. New tube ordered.

160/BE3/118 main
Does the '160' refer to the air corrector? SoCalGuy wrote: I agree with Ginch, stick with 2%. FWIW, I'm currently running a 24/24 carb on my Polini 177 with a BGM pipe. Jets are 38/120 idle, 160/BE3/118 main. It's dialed in pretty tight. Good luck. |

G'Day again All.
The vagaries of post covid life mean that I don't get a lot of scooter wrenching time or post wrenching MV posting time!). Unfortunatly during the Covid lockdowns, I let HanoiJane fall out of registration, which is an absolute palava to fix. So she sat idle in the back of my storage lockup. Buuuttt.. a few months ago, I pulled her out and trucked her over to a buddy who's running a sccoter resto biz, got him to get her road legal and registerable again, then, having jumped through the hoops to have shiny new plates on her, I got him bolt the fun bits back on, and get her back making semi legal noises. So since about November, I've been hooning around town to and from work, Spec at that point... Vietbodge Super frame on 10" wheels Malossi MHR177 Mazzucchelli PX200 bell crank with 60mm stroke, 110mm conrod ,Grand Sport Gudgeon pin conversion bearing and custom packer 5mm packer. LML reed 150 cases, JB'd and ported to match MHR. Malossi 150 PBHB kit with PHBH 30, Malossi intake, reed and bellows, plus custom adapter to LML case - intake and case both milled and matched to 200 spec. BGM Fast Fuel tap Banded sip Cosa 2 clutch 22/67 primary ratio p200 gearset with T5 4th Sip quickroll Koso digital EGT and AFR SIP speedo and egt Vespatronic at 23 degrees at 2500 RPM Custom loom with battery for gauges, and usb charger Sip Front shock with standard spring KYB rear shock Crimaz front disk Transfer at 122, Exhaust at 180 S&S pipe Which was pretty fun around town, if bloody hard to ride. Idle needed to be about 1600 rpm, and it was rich if off pipe (below 5500) then sllightly lean when it first got on the pipe, then it just took off an screamed up to 9500 rpm. Usually with the front wheel disengaged from the ground most of the way. Fun time. More to come |
