why does my bike hate pipes

my V1 hats pipe it simply will not run with them

this is my 79 carabella with v1 motor 90 kit 18mm intake 21mm phbg carb

bike runs perfect with no pipe as soon as I try a expasion pipe (tryed 2 diffrent ones) it puff if im lucky i dont unserstand this???????

i notice fumes pouring out of the pipe(the mounting side) when I hurry up and take it off its like the pipes cloged but there not there stright pipes

i dont get it i need to have some sort of pipe so i can muffle the sound at a least a lil bit my neighbors are going to kill me

Josh, is the engine 100% Minarelli, or are you using a Carabela engine/bottom end with a 90cc top end?

Re: why does my bike hate pipes

have you tried tuning the carb?

Re: why does my bike hate pipes

sounds rich.

`SABAT!

Re: why does my bike hate pipes

which pipes have you tried again?

Re: why does my bike hate pipes

Damn straight edge moped.

Re: why does my bike hate pipes

The REAL v1 OR clone mexico carabela...

What one are you running...

The carabela can not use the .. polini or any regular v1 cylinder be cause the main transfers are different.

Re: why does my bike hate pipes

yes its 100% Minarelli

Re: why does my bike hate pipes

im runnin REAL v1 can send pics u know the tunning would be diffrent but I would think it would at least start with a pipe

idk

Re: why does my bike hate pipes

ev racing scorpine pipes and of corse the stock pipe wont mount up to that kit

turn off that nitrous kit!!!!!!!!

Re: why does my bike hate pipes

You mean turn it up right?

Re: why does my bike hate pipes

For the 90c kit the number in the boost port should be on the intake side, right?

Re: why does my bike hate pipes

I dont know what the kit says but I thought any marks went to the exhaust side.

Re: why does my bike hate pipes

the only mark is the 51mm no arrow

Re: why does my bike hate pipes

did you try changing your jet out to find the appropriate one for your pipe?

Re: why does my bike hate pipes

Up jet

Down jet

Install neons!

Only pipe I run is roor!

Re: why does my bike hate pipes

im rinnin a 112 main and a 60 idle think with a pipe I should upjet alot?

heres a weid thin will run with a pipe if I put a shop vac on the tail pipe

Re: why does my bike hate pipes

Put the biggest jet you have in and see what happens.

So it runs if there is a vacuum on the end of the pipe? Are you sure it is not clogged?

Re: why does my bike hate pipes

112 is probably way too big.

also, "nitrous kit" is a joke, right?

Re: why does my bike hate pipes

I can shine a light through the pipe and its clean as can be its bran new

Re: why does my bike hate pipes

with a 112 it runs prefect any leaner and it starts to get hot

Re: why does my bike hate pipes

and nitous kit is not a joke

Re: why does my bike hate pipes

I have a 100 in my 21 carb on a 90cc kit and its rich. That's with a puch bullet. 112 ought to be too big. Maybe you have a problem that's not related to tuning, like an airleak?

Re: why does my bike hate pipes

i always thought airleaks were the first and only step to tuning.
