Weird - you can tell the issue is in the rear as the belt stays loose while you were trying to turn 'er over. My first guess and my second guess would be your clutch. The starter clutch/bell can stick, grab, and make it impossible to turn. Take of the rear clutch off again and check it out....see if there's any metal flakes or residue too, and turn the gear spline with your hand just
43.mm though - looks like a more universal decomp hole-e-o
I had a nightmare this summer with ignition coils. I was having the same symptoms..just started firing bad once I got the RPMs up and they wouldn't rev out. It felt like a clogged exhaust....It was a shorting Ignition coil.Normally when an ignition coil goes bad you lose spark...lose your mind changing plugs, condensers, and wires until you find it's your internal ignition coil /switch
It sounds like your seal started leaking, but this does ring like a classic carb issue. The reason it sounds like a leak is that (as someone mentioned) it sounds like a vacuum leak is causing heat and loss of power.
Man....that thing is nice. I'm always looking for a 2nd, so if it hits the Bay Area CL we'll see it and alert!
Sounds like your sucking something in the carb...when you stop it settles only to find its way again. Clean your idle jet
Clean! She's Beeeaaauuuuuutiiiiifuuuul
Also, eliminate your idle jet being clogged - it's kinda hard to clean/see inside the carb. It sounds like you made progress cleaning the carb..i'd keep working there a bit.
I had this happen to me...welded a training wheel bracket on and it lived. Take it back to your welder and have him finish it better.You need to score a Si subframe(you may have to bolt or weld brackets for the rear shocks..means you need longer a new belt too/ Welding that crack is the best way to make that rally.Welcome to Vespa life;)
I'm still failing with my Malossi High comp head.....spiking temps / so it sits on my shelf til I get smarter. I suggest you throw a stock head on...fix that decomp leak( you should be able to drench the face the head with carb cleaner without phAzing the engine. Also...get some real gaskets...Treats has 43mm Athenas right now / you still have variables.
Dude! Stop cutting holes in stuff. I'd like to help but you create a bigger mess with each post. First..on a mid set-up/ small carb you shouldn't have anything bigger then a 70 on there. Second..you need to start over- put on as many stock parts as can(you can leave your pipe and 13:13 on. To survive Vespa you must keep it waaaaaaay simpler. Good luck!
Ren, once you talk about air gushing at the front bottom of the engine chances are your just feeling the fan which is normal function. You won't physically feel a vacuum leak.I check temps in different spots with a laser gun

Yeah Ren...you got a leak somewhere. You shouldn't really be hitting over 300, but also shouldn't need a jet bigger then a 68. All my builds are running off 64 or 66 main jets, and they rarely reach 300 at the hottest parts of the cylinder..nothing about 260 on the head. I know people run above 300, but for me that always means a problem. Check these areas with your carb cleaner:- ca
Hey Jim....I'll buy the cases...internal ignition coil too please
Messed up the GoPro setting - gell-capped at 26 seconds(shout out to Ray Ray on the Vespa caboose!)
I don't think you would feel an air-leak...you probably dust feeling air from the fan. It's supposed to do that. I would start matching cases,intakess, and don't cut your crank. You're just making a mess. Find the leak(sounds like base gasket or exhaust). You should be jetted from 64-68.
Check compression...use a head gasket. Are you sure your crank seal isnt leaking? You should be hitting 45 easy with that kit.
Have fun - looks like I ain't gonna make it...kick Satan in the nuts for me!
Jersey for life! If I could I'd get on the 80 and stroke it all the way home / have fun✌
I tried the Spaco clone...so cheap the mixture screw moves with the engine vibration...had to Teflon rap it/ wouldn't recommend
Yeah...I just kinda looked and there's not enough meat for those threads, but when the thing was busted you could see that the flange is a separate piece that is insterted into the port when machined. There looks like enough room to bore that out...and get a piece in there that's 27 OD.....then we're blastin!
Yeah / if this weld doesn't last I'm gonna try for a 27mmOD. Barney I don't think I have a crack....what makes you say that? That shot scares me as I've gone through a couple. I've been good since running Si subframes.
Dillon/ I don't use springs but maybe I should. I got it welded at the NASCA track here in Sonoma. I thought the springs were a backup if your shit falls off
Can I drill threads for this?http://www.treatland.tv/vespa-malossi-BIG-D-E-P-S-22mm-exhaust-adapter-p/vespa-malossi-adapter-156345.htm
I broke my exhaust off when tightening. It's aluminum, and I didn't know you could break a flange by over-tightening the collar clamp. I did have some recent issues with part of my frame eating belts/ Iv'e had some recent friction and vibration, but nothing extreme.I've had problems with Pinasco shit breaking, so it might have just been crappy.What can I do? My local muffler
Hey MarcThe only meaningful exhaust leaks for me were due to me letting the collar/clamp ride to far / up 'n over the top of the header. Make sure the header is coming all the way up through past the clamp. In your pic it looked like this is what may be going on.I've had other leaks, but it usually just got messy..not a vacuum leak or effect on heat.
Derek...while the Polini cheeks are taller, their gap is 2 mm wider then stock pullies when fully compressed, so it doesn't matter that the pullies are bigger because the belt rides lower. I took a pic,but its hard to tell from it.
The multivars aren't bad with circuit pipes/ it's the loud calibrata that amplifiEs. I don't have any big Vespa engines, but I would guess adding a 19 PHBG to the mix would really make em pissed
Hey DerekSonoma's a valley, and I don't need to climb much. The're are two reasons that I(not being a pro) prefer my modes Var:1. Sound. Hella old people and yuppies here that hate, and with my Calibrata is just loud for a mid-kit.2. It gears me down and powerbands too early. I could put in more work with weights to get this right, but..I slap it on if I need to keep up with a
