Smart— will give it a go!
Not a bad idea. One side has a lip, though, so I can't lap it. Definitely a few little nicks here and there. But yes, next move I think is going motoseal sans gasket!
Original av7 case for motobecane 40t will not fucking seal!! I’ve opened and resealed several times and cannot rid myself of an air leak. Same spot every time, just below intake (but def not intake itself).I’ve tried sealing with no gasket, a dry gasket, gasket in 2 stroke oil maybe three different times, and finally a dry gasket with yamabond 4 spread thinly on each case half.Is it warped? Time f
What ya got on it? What’s the story?
Thanks for the input, folks. Just to reiterate, she starts up and runs great as-is.What I'm gleaning from all your info is that the starter shoe/spring setup in a stock variator is perfect for a stock head with decomp engaged. But when a hi comp head is added without decomp, the springs need to be lightened for the starter shoes to engage more easily.Hi comp head= way more force needed to get
Results are in (but some of you already knew this):Doppler 50cc hi comp head indeed improves torque/overall performance. It is fairly significant! BUT, it is unreasonably hard to turn the engine over to start it. Lots and lots and lots of pedaling and downhill to get it going.This is compared to the stock head with decomp, which I can kick once cold and it’s up and running.Is there some middle gro
How hard was it to start? With the stock decomp head I have no leaks, and it basically fires up when I look at it.I'm not worried about working a little harder to start the Moby, as long as a hi comp head has enough benefits to justify swapping it out!
Haha right on, will give it a go.
It’s got a Dell 15.15shorty intakeadded a stock variatorPorted the intake a littleLe partie CDISet timing at 1.2 BTDCMostly looking for a little more torque with these SF hills! I know I just need to bite the bullet and port match/ do some porting, but want to get the most out of what I got until I get around to that...
Got a stockish Moby 40t, and wondering if going to the doppler 50cc head with no decomp will make it impossible/hard to start.Any advice/intel here? Would performance gains even be worth it?Here’s the head w no decomp:https://www.treatland.tv/motobecane-doppler-50cc-head-p/motobecane-doppler-50cc-head.htm?gclid=CjwKCAjw6qqDBhB-EiwACBs6x7vJNEWPs-7oji_ED97m1Fv_sf_5Lxmwq8Q_U49bmSlO7aqE066rOxoCtUwQAvD
I guess I was just wondering if maxing out airflow and jetting appropriately would always lead to more power/speed. Or is it always just a matter of balancing the two, and it doesn’t necessarily matter what the size of the jet is as long as it’s balanced with the right airflow?
What is the performance difference between more air flow + bigger jets vs. less airflow and smaller jets?Moby 40t with:Av7SHA 15.15Le Partie CDICashew ExhaustStock VariatorBH6S plugCheers
Is this concerning?? Bike rips, but there's a gray oily substance leaking through one of the rivets of the pipe.Haven't noticed any difference in performance.
Here for the muffler if it falls through

Everything stock, btw, except for le partie CDI and SHA 15 carb.
Which variator should I nab if I want to add one to a non-variated av7 on a Moby 40t?Is it as easy as just tossing it on? Have read things about changing out gearing, tension springs, etc.In SF and looking to be able to take on some hills!
Thank you! Gonna nab one and throw it on.
Just manned up and yanked 'em out with pliers.
Got my 40T running nicely with the le partie CDI, but have yet to wire up the lights— which voltage regulator should I buy?? What do you guys run?
I heated my av7 with a torch and was able to tap the bearings out pretty easily. But the seals are completely stuck- can’t get them to budge.Any other tips or tricks?
Silicon gasket maker FTW. Super glue definitely fell apart.Applied the silicone once and holding strong!Thanks all.
This thing still available??
Super glue has worked great so far, but I think silicon gasket maker will be a better long term fix without dremeling away the mounting plate. I don't have a flywheel cover but might end up nabbing one after I tack down timing that I like. Thanks all for the recs!
After riding yesterday and today, the flywheel continues to chew through the magneto wiring! Looks like I'll need to find a better way to tack down the wiring harness to keep it out of the way. The rubber mount slips in and out very easily, so it probably jiggles itself into harm's way as I ride. Taking suggestions as to how to keep it in place, but might just try super glue.
Recently bought a 1980 Peugeot TSM-U that had been sitting in storage for six years, but just prior was kitted with some fresh goods:Ported 70cc Gilardoni w/ 49cm Peugeot headDellorto PGHB carbMalossi MultivarNinja G3 PipeI basically put a fresh bulb in the headlight, air in the tires, gas in the tank, and with a lot of kicking and pedaling got it to fire up. It ran GREAT. Totally ripped. Every ti
sorry guys, I'm that asshole. Airleak at the intake.
so I've put in a 102, a 104, a 106, and all of these jet sizes are still resulting in what may be a soft seize. At WTO it sounds like it is fourstroking, then soft seizes.is that even possible? I've set my timing to about 16 degress BTDC, or 1 mm, and this hasn't really helped the problem. Point gap is stock. Anyone know what the ideal setting is? Is it super duper sensitive?
