After a whole lot of trying to convince myself out of it I have decided that to get the kind of moby speed I am looking for I gotta go av10. I am planing on using most of my av7 plus the case from an av10, I think i have seen several people say they had this setup. Anybody that has done this run into any problems? Also if you know anyone in the states that has an av10 case that they are willing to part with let me know.
Av10
Re: Av10
the only thing u will find you really need is the engine tension spring mounts on the engine, if u build from the ground up av10 style. If you can make the part or have somone make it its the cheapest option to build from aftermarket parts completely. and use stock av7 parts where you can.
Re: Av10
Just get an av10 from ebay France and rebuild the motor with fresh bearings and gaskets. It will save you a ton of money, assuming what you get is any good.
Re: Av10
So the the top mounts the same and I need a different spring setup on the bottom? I am planing on getting a lower tension spring to go with the expensive ass variator and clutch pulley. Damn French ladies are expensive.
Re: Av10
the existing spring setup on your 50v will work, you just need to replace the brackets on the motor that secure the it to the spring
Re: Av10
yo man it really depends on the build, what do u want from the bike, if ur getting the sick doppler transmission setup like u said ur gonna need a powerful engine to make it work
Re: Av10
Yea I'm going all the way with this bike I gotta show everyone in Sacramento what French bikes are made of. While I'm on the topic what kits have people used on av10 and what did you think of them. Planing on staying air cooled but who knows.
Re: Av10
malossi, 70cc kit, is sick and will take u to 50+ mph, its also solid as hell and really nice craftmanship from the factory (unlike polini)
doppler 50cc kit, revs maybe be even higher than the malossi, and will take you to 50+ but without the brute force of the 70 kit. works best with the doppler high comp head that it comes with, but also its sans decomp valve, still startable from the drive side tho. excellent port design, rivals polini, superior craftsmanship, a real 50cc gem, the transfers on this thing are larger than the ones on the 70cc malossi.
If u want the 50cc feel and glory of 50:50 go with the doppler, if u want raw acceleration annd power go with the malossi.
polini makes a kit as well thats easy to get, there are others too... check brets post on all the french parts ever with pics.
Re: Av10
i've read excellent things about the malossi G2rr kit, and on ventilxp its actually the kit that almost everyone unanimously prefers. its liquid cooled, but the G1r has the same port map if you wanted to stay air cooled. it apparently revs super high, somewhere in the upper 10-11,000 range without work but has no low end so you'd definitely have to spend some time messing with your variator to get it dialed in. also a clutch pulley is a must and a lauch pedal would probably also be a good idea.
Re: Av10
Is water cooled worth the trouble? It's still only 70cc do people use real high compression or something to get the heat up?
Re: Av10
where do you get that 50cc doppler? the only 50cc ive seen around is parmakit or something.
Re: Av10
you can get the doppler at rcv-team.com and la-becanerie.com.
the watercooled kits come with cylinder heads specifically made for them as opposed to most of the aircooled kits where you still have to use your stock head, so i'm sure compression is higher.
Re: Av10
compression is pretty high anyways
with a stock 50cc head (no gasket) on my Proma 70cc kit im getting like 220 psi.
Re: Av10
Still why go water cooled if your cylinder isn't overheating? Higher compression makes higher heat that was what i was wondering, but it sounds like air cooled runs about the same CR. Any clarification would much appreciated as I am sort of new to 2 stroke performance.
Re: Av10
Watercooled kits are safer, as the outside temperature has almost nothing to do with your cylinders temperature. If you're in Portland, your aircooled jug is getting blasted with cold rain and constantly changing in temperature.
I've seen some watercooled kits ported much more aggressively. Since the temperature is much more stable, they're less likely to seize.
Honestly, it's just a moped and having a radiator is only for people who really want to tune their bike (bret's bike is amazing).
Re: Av10
mallossi!!!!!!!!!
yeah watercooled if for show really or if ur going to the race track.
I want it cuz its just sick to have lol, but honestly the air cooled malossi kit i'm running now is just as sweet.
does the watercooled kit come with a decomp bret??? i can't remember, thats an issue too
Re: Av10
I think the radiator kind of ruins the lines on the bike and if there isn't huge power gains I might hold off. I also figure that colder cylinder means colder fuel/ denser fuel charge which means more power, might be kind of like an inter-cooler. I have to get used to how 2 strokes work different world from my 64 mustang. Mallossi stuff is good I'll probably go that route.
Thanks everyone
Re: Av10
Alright so I am in the process of buying an av10 case and wanted everybody's input. I noticed that there is considerable differences in the induction port size I am assuming this is because of different aftermarket cases. Also many of the cases say they are g2 which i believe might be a racing class, maybe?? Anyways am I getting myself into a parts finding nightmare if I get a non stock case.
Thanks
Re: Av10
almost all the kits now produced match the stock three port transfer. AND AND you can port the stock case to match even the most extreme kits.
Don't try this with peugeot, btw.
Re: Av10
I think the only reason to get an aftermarket av10 case is so that you can use a 4 petal reed cage.
you can also get a little adapter thingy to use a 4 petal on a stock case, but its beyond my knowledge as to the performance differences between the two options.
Re: Av10
Polini 4 petals shatter. the one inthe adapter has broken on me twice, and elliot once, and it's the same one that's in the polini cases. Just use a Doppler Carbon two petal reed and be done with it. The four petal isn't that much bigger than the two petal, and i don't see that much difference without it.
Re: Av10
power bret umlimited power!!!
i like the polini 4 pedal but it is prone to breaking, technically i never broke mine but ordered one from french ebay and the seller neglected to mention it was already cracked so i could never use it. the replacement i have has not cracked....yet.
i think the only real good reason to go with polini cases that mount the 4 pedal to them is to be able to make a custom intake with an even bigger reed block setup than the polini one, since the polini cases come with a bigger hole you could run like a gillerdoni reed cage (huge) with a custom intake if you wanted to get crazy.
the 4pedal polini intake system is maybe a mm or 2 smaller than the polini cases and puts the carb in a more attractive place and uses stock cases.
if your going all out most power possable i'd say go with the larger intake, the 2 pedal has more tuning options, such as swapping reed thicknesses, and will still pull very well
Re: Av10
So this break> would take the 4 petal reed valves, I can make an intake the reed valves might be hard to make though.
Re: Av10
You really don't need anything but the stock cases, and a little gusto, and maybe some aluminum stock, to get huge porting configurations.

Re: Av10
yeah bret nailed it, i mean one might as well make av10 cases from av7 cases if u'd gonna go that radical.
nate can do all this for you tom but it could take forever, i wish i knew how to weld ,and had a machine shop, unlimited cash, a space to work, and all the time in the world....
o well, maybe later in life
Re: Av10
Don't we all wish we had a money tree out back next to the machine shop. I'll keep looking for stock cases. I also found a mallossi crank that is supposed to give you a few more CC's, I love French ebay.
Re: Av10
please link to that crank
Re: Av10
here's the link
but it already ended maybe he will repost.
Re: Av10
I am under the impression that ebay seller is full of crap or he is not mentioning what sort of cylinder head you have to use with it.
I can not find the part number '53 5505' in the malossi catalog.
The piston would hit the cylinder head if the crank was made any longer.
Re: Av10
not with spacers, but watever, the parts war has ended, now what you do with these super parts is the new question, i'm sure nates cooking up some sweet stuff... umm good. i'm gonna start messing with the clutch pully and go for motorcycle accleration. i also want to play with gearing and restricting the variator
