Yes, If u want to stick to widetyre try 130/70-10, it has the same ratio as 3.50-10 about 7% smaller circumference than 120/90-10

It will make a hole lot of difference to the 4th gear.

... I think a 60mm crank + rear tyre 3.50x10 or 130/70x10 and a standard exhaust or a racing pipe like the Taffspeed MK1, PSP, Swift, etc... could solve your problem. You won't need high rev',s the thing you'll need is torque...

[patrikgrann]

Please let us know what and how u did! :grins:

Best regards

[sidvespa]

ok thanks for the info

the first thing i did was change the jet back to a 116 this has ended the cholking

the second thing i orderd a new tyre a 130 70 10

the cosa clutch 21 i have to try again when i have the time to put it in in a few days i will have the key to our new house with a large garage :love: and i have to work on this also to keep the wife happy

sorry for my question but some of you don't understand that i live in belgium and over here there is a scootercene but it is not so big like in germany and we only have a few side-cars manly on a standard vespa or lambretta so i have no one else to turn to

grtz sidvespa

ps i will keep you posted when i change something and sugestions are always apriciated

Hi sidvespa!

I´m having a Px200e standard and a cozy sidecar, it works ok , but not uphill :grr: . so i´m planning to use a 60mm crank and a 1,5mm headgasket for more torque and a 4th gear from 125 and keep the rest standard.

I have the same problem in Sweden, not many scooters with sidecar and a house and a wife!

Have a nice summer!

Not the same setup, but it might help

Rally 200 engine converted to PX 12v ignition using half casing.

Piston 70,4mm so gives 221 cm3

short 4th gear from a PX125

SI 24 carb, with 125 main jet, no autolub

Sidecar is a Cozy been clocked at 90 km/h in 4th.

You don't see many sidecar also in France.

[patrikgrann]

Piston 70,4mm so gives 221 cm3

Hi Lor@n

What kind of piston is that? :haeh: Is it used on a original cylinder?? or is it a tuningkit?

Best regards

Patrik Grann

[Lor@n]

Piston is used on an original cylinder.

When I bought it in FRANCE, it was advertised as a "230 japanese" conversion.

I've seen them on www.beedspeed.com years ago, don't know if they still sell them.

[patrikgrann]

Is it perhaps VE+ piston?

[sidvespa]

now i have f**k it up big time :uargh:

just blown a hole in the piston of my pinasco ( when i was getting the new tyre(130 70 10) so now it wil take some time before i can tel you about the changes i have made

first i am going to do the new house an them i will probebly put an other standard engine in it the engine only needs a new crusefix and bearings

grtz sidvespa

[patrikgrann]

Ooops!

Sorry to hear that! Hope you get it sorted!!

[sidvespa]

i also hope it

i am going to put the original barrel back on it

and drive this way again

grtz sivespa

[Dr.Paulaner]

ignition timing wrong?

wrong jeting?

Marcel

[sidvespa]

i think wrong jetting (to small)

i have drove the pinasco barrel alreddy a 1000 km with the O exhaust without problems and then put on the JL exhaust and dit it wrong with jetting

now i have an other question with an JL exaust and a O barrel shoud i change the timing or keep it the same as with the O exhaust

the mark A behind the flyweel

thanks sidvespa

[patrikgrann]

Hi Sidvespa!

I think you should keep the timing as it is, and just change the jets if you are going to use the JL on the standard engine.

But I think you should use a colder sparkplug, NGK 8 or something like that and try it out!

[patrikgrann]

Hi all you sidecar fans!

Why don´t you tell us none Germanspeaking scootersist about your engine setup???????? It would be nice to learn some more about what we need to do to get our sidecarscooters work perfect.

OT: Probably those who drive sidecars are not speaking english well enough or think they don't and are afraid of disgracing themselves. Be thankful for your very educational TV showing non-translated american movies. :grins:

Unfortunately I have nothing enlightening to say on topic.

Hi there anyway

[patrikgrann]

Hi APO and thanks!!!

You might be right, but it´s to bad. My Enlish is far from perfect and it does not matter as long as people understand what one is trying to say.

Always nice with a answer

Best regards
