Hey y’all, trying to figure out which exhaust will give me better performance/ top speed.
Techno bull it or the other techno I have (forgot the name)
Bike has:
CDI
70cc treats kit
High comp head
Stuffy crank
Which exhaust is better on a kitted Magnum
Re: Which exhaust is better on a kitted Magnum
Hmm , you have two pipes .
One is mounted and supposedly ran . So , you know what that one does .
Maybe mount the other one and find out what that one will do .
Every bike is different .
ONLY you can prevent forest fires . ;)

Better yet, check that sweet rear brake cable.
Re: Which exhaust is better on a kitted Magnum
the estroili on the ground is a way better pipe.

He don't need no brakes to go fast.

OH o ... LOL
Re: Which exhaust is better on a kitted Magnum
Based on the zip tie cable extension and red tape over a bike light, you probably have more to worry about then which pipe will give you a mile per hour faster.
I honestly have not been able to tell a huge difference in performance in the 2 pipes. The Estoril is a way better pipe with the lows and the mids being much nicer. But as far as top end it may only be a couple miles per hour difference.
Now the only question. Do you know how to tune your carburetor for the pipe? If so I would put the Estoril on there and tune it correctly and look up how to correct the size on your brake cables. Buy some Knaps or make your own by drilling a hole in a bolt. That whole thing looks like a recipe for not being able to stop when you need to.

The cables though they need fixing aren’t necessarily his fault, the aftermarket puch cables I’ve been complaining about for years because the internal cables many times are made too long compared to a stock cable,
I think benji corrected the problem on latest batch of puch cables he sells but otherwise you need to stock nos puch ones, I don’t like using Karps on brake cables because they crush some of the cable flat weakening it
(When you crimp a twisted cable flat some strands are tight and some are loose, it decrease the strength by 30-40%) as well as making a corrosion point and it can fail, having custom length with cast metal ends like motorcycle shops used to do back in the day is best,
They do make a adjuster you can add before the other adjuster that I’ve used a few times instead of cutting the cable and crimping it flat,

Oh I don’t disagree but...

Yeah I just noticed that the brake cable is routed incorrectly in the swingarm when it should go outside, damn that’s horrible,
This is correct mounting of rear break cable
Even though this is a first generation 1978 Spanish built puch magnum XK (winter beater) the cables route the same way on all magnums,

How would one tune a carb to let say....that estoril? I thought a carb tune was a carb tune, teach me.

A proper carb tune takes place after all other modifications are made/done .
Change one of those modifications and the carb tune will likely be off .
It's why a carb , fresh out of the box , most likely will not function properly . (edited)

I think what he was trying to say is that how is an estroil different to tune than other pipes. It is the same as tuning other pipes. Just have to jet accordingly

You may be right .
I wondered , as he seems to have been around for a while .

Thats what I meant, for this particular pipe, I get the rich/leans, highs and lows.
For example someone said it hit well at low and mid, should the tuning at those rpms match the pipes powerband? Is that what you mean tuning a carb to the pipe?
Re: Which exhaust is better on a kitted Magnum
they just mean different pipe might have slightly different final tuning, but in this case probably not much different between the two.
on some setups you can give the bullet's more timing because they run cooler but i doubt a 70cc treats kit is going to care that much
