Mallossi long stroke crank?

Baltard Drought /

Are these for real? i used search and really didnt find much about it. Longer stroke wont increase CC im aware, but what if any are the benefits to running one? Anybody using one right now?

Re: Mallossi long stroke crank?

yes. they are real. and cc's = bore x stroke, btw.

Have you used one? If im going to tear apart this case im putting it back together right.

Re: Mallossi long stroke crank?

correct they do not increase cc but they do cut down on engine vibration. resulting in higher rpm's. i use one. besides what kind of person doesnt like a longer rod

Zing! would it work with the ducati CDI?

there isn't a good reason why it wouldn't. fires the same as always. its still the same stroke, just further away.

I just hear setting the timing on a pug is hell.. BUT if im going to build it i better do it the right way and blast.

Re: Mallossi long stroke crank?

id wait a wile before buying the cdi. i have a strange feeling some 100$ ones will be on the market soon

Re: Mallossi long stroke crank?

Well I have alot of work to do on this engine before i'll be getting it anyways,.. is the CDI easier to set than points? this engine/ exhaust is easily costing me over 1000... I want to do it right So if the CDI is easier to set. I'll wait it out, but definitely go CDI. also, is there a write up on how to do the variator swap as well?

its not that hard to set the timing. just need a timing light and some patience. a timing dial is nice too

Re: Mallossi long stroke crank?

I've never done this, is there somewhere i can read up on it? I'm new but I learn fast i just need a place to get the info. Would this be in a peugeot manual?

Re: Mallossi long stroke crank?

i liked my stock variator better. than this nice one. all i gained was a little bit of low end not worth the time and effort of the proformance one not to mention you have to grease the doppler pulley like every time you ride evidently.

cdi is worth doing but points work

Re: Mallossi long stroke crank?

Baltard Drought /

but i mean when I change the crank i'll have to reset timing and whatnot correct? peugeot manual should have how to and an exploded view so i know how to put it all back together?

Re: Mallossi long stroke crank?

this is probrobly one of the most simplistic moped motors ever made just taking it apart will be enough for you to put it back togather and set the timing at 2mm btdc

Re: Mallossi long stroke crank?

Any instruction on setting the timing though? or how to use a timing light, I know total newb but I gotta learn somewhere.

And really thanks for all the help, this shit can get confusing sometimes.

Re: Mallossi long stroke crank?

so, stroker crank=

better at high rpms, but it can lose a little compression because of the extra gasket with the spacer.

i have no direct comparison to say if i notice a difference.'

cdi fun times.

Re: Mallossi long stroke crank?

They are not a stroker crank, they just have a longer connecting rod. I don't see that feature making any difference, but i'm sure its still a nice crank.

Re: Mallossi long stroke crank?

Compliments of naz from about a year ago:

Longer Rod Pros

Less rod angularity

Helps resist detonation

Reduced piston rock / load

Better leverage on the crank for a longer time

Less ignition timing is required

Allow slightly more compression to be used before detonation is a problem

Less average and peak piston velocity

Peak piston velocity is later in the down stroke

Less intake runner volume is needed

Longer Rod Cons

Makes the engine run a little more rough at low rpm

Reduces scavenging at low rpm

Shorter Rod Pros

Increased scavenging effect at low rpm

Slower piston speeds near BDC

Can allow for a shorter deck height

Shorter Rod Cons

More rod angularity

Increase side load on piston

More ignition timing is required for peak power
