Hey Guys,
I just picked up a peugeot 103 and I'm having a hell of a time with the carb. From what I have read nobody seems to like these things very much. Does anyone have a suggestion on a good replacement for a stock motor that I am also planning to put a pipe on? Also would it be worthwhile to use an aftermarket variator on such an application?
The carb's really aren't THAT bad. just a bit tempermental at times... A good cleaning will get'er back up to par right quick :D
You should pickup a 14-16mm intake from treats on ebay, replace the reed-cage with a tomos one, and slap on a 15.15 or 16.16 dellorto :D
Pipe... you should be able to derestrict that badboy, and w/ the above setup hit close to 40ish :D
Grats and welcome to the french family ;)
Ive actually researched a whole lot on this carb and done everything I could find to make it work, the big problem I have is at idle no matter what I do it just wont run right, I have resealed the intake, cleaned and soaked the carb, redrilled the main jet to the proper size because it was gunked shut, and then I found a local shop that showed me a way to unclog the idle holes and that still didnt help, another strange thing is that the Idle is stuck really high and I cant get it to come down.
I'm kinda new to mopeds but well versed in motor cycles and cars so I know enough about carbs to get by, to my understanding the screw in the side is used for the low speed mixture but if I unscrew that enough to drop the idle the bike won't move at all and tops out at like ten miles per hour so I think I am giving up on this carb.
any Idea where I can get a dellorto, also any pipe suggestions?
high, uncontrollable idle could be an air-leak.
Dellorto = www.dellortodirect.com
Try the SHA 15.15 or 16.16 :D
Pipe.. you kinda gotta goto france pretty much. Or, you might try hittin' up someone doin' a group buy...
Anyway.. ditch it cause it's likely kinda tiny anyway :D
"treatsHQ":http://myworld.ebay.com/treatshq generally has nice goodies for french bikes, especially Peugeot's :D
Just shoot him an email, cause sometimes he doesn't list all he's got =P
As far as air leaks go I have resealed the abvious and I know the carb and manifold are not leaking is it possible to leak from the exhaust or maybe the cylinder?
I was really stubborn about changing out my gurtner peugeot carb. Then I realized I had a peugeot 103 LS U1.... U1 as in the tiniest carb you can imagine. It would top out at 20mph and the thing was clean as a whistle. From the sound of it, top speed isn't your only problem.
treats fixed me up with the following:
1. Dellorto SHA 15.15 carb (cable choke model, for your handlebar lever)
2. Peugeot 14-16mm intake
3. Parma reeds (cause your stock reeds are too tiny anyhow, especially for a 15mm carb)
4. Two Puch throttle cables, since your adjustable knarps are way too big to fit inside the dellorto you'll need new cables.
5. Some jets range 54-68 for tuning.
I got this stuff extremely cheap, probably equal to bulk cost. My bike tops out at a little bit above 40 now, and I could probably go a little bit more lean.
With this setup are you running the stock pipe or after market, also is there any to buy from treats without using Ebay?
just wait till it doesn't get spark haha
Just send him a message over e-bay, his stock is usually far beyond what he pays to advertise on there.
With any peugeot that I get in the shop, I generally take the restrictor plate out of the exhaust, put a dellorto SHA 15/15 cable-choke carb on it, and replace the ignition coil with a bosch.
The carb setup is always no black air box (just the screen filter, because the air box scrapes the frame) and a 68 jet works perfect for portlands climate.
Monsieur Sabatino,
You use the stock intake on them badboys? or one of the larger-ish ones?
I'm thinkin' to get the TSM up and rollin' w/ not-quite-stock status for a bit while I wait for my pile of money to get larger lol... Waitin' on an intake, and then she should rip :D
P.s. Hi! long time no see~!
Where can I get a hold of a bosch coil, my peugeot just started stalling when I hit the brakes and I hear thats a tell tell sign the ignition is going bad?
Casey:
The stock intake works fine. Bikes will go 38-ish just like that. I have a big-ass intake with a big-ass reed on my 104, but for an easy clean fix, they mount nicely to the stock intake.
The 15/15 also comes with the right jet in it!
Eric:
I know Handybikes has the bosch ignition coil. It's for a sachs. The one for Puch works better, but is harder to get. You just have to grind a small tab off of the sachs coil and it works perfectly.
How good are you at wiring?
I'll make a wiki entry about peugeot wiring if you need a simple diagram.
funny thing I make a living off wiring so I would guess I'm ok at it, I just need a schematic and I can do it. send me pdf or a pic and I will figure it out. By the way thank you so much for any help I'm having a hell of a time making my bike run right.
