Advanced timing

[Banshkid]

Hey

so I know this has been a topic of discussion before, I’ve only seen older forums but not necessarily the right answer I’m looking for.

I’m a “noob” to the banshee world I just bought mine last year that already had abunch of mods done to it, I’ve learnt quite abit from reading on here so I’m blessed this site is here😝

so basically my question is hoping someone has some insight on this for me, I had my dad do a full rebuild on my engine, it let go after 15 hours of riding it there was multiple things they were half ass put together when I got it, but anyways it has a timing plate on it and I didn’t start looking into the quad until after it was built and I started putting the bike back together, it hasn’t been started or ran yet but I asked my dad about the timing he said it was marked at +11 and that’s what he put it back to, I’m assuming this is definitely one of the things that went wrong with it in the first place, I’ve noticed here that +4 - +6 is the sweet spot depending on what mods you have going.

basically I’ve been wanting to bring this up to him as for I’m concerned about what will happen but hill just think I’m full of it, I would just like some back up proof as to what’s going to happen in this situation in the future

From what i know advancing timing is igniting fuel before top dead center which is beneficial at higher rpms thus we have cars with variable ignition timing and variable valve timing on engines.

If you advance timing far too much spark plug will ignite fuel too early and will expose pistons and bearings to much higher loads than normal.

I would not go over 4°  on a new-build, especially when you don't know what the original problem was. also since you don't know what the original problem was , I would check your squish and do a leak down test , when done assembling.

Got pics of old Carnage?

Also make sure the timing number that is desired is lined up the case halves crease.

Yeah that’s what I figured, what do you mean squish?

An I would upload a pic but it won’t allow me👎

Type
“Squish banshee HQ” into google.


Squish is the clearance between piston and head at TDC.

So quick update question

i went out an bought a puller because I didn’t have one, I dug into it and found out the timing was actually set to -1

on a stock motor should I run it at +4?

[375hp banshees]

Yes unless you had previous issues , that could have been related to timing

Yeah that’s what it was set to before and resulted having a hole in the top of my piston

I haven’t started it yet, I’m still finishing up afew things but I hope it will run better now

I’m aware of that, I’m guessing stock is just at 0?

[375hp banshees]

Stock is not adjustable,  but It should be. 0=stock & stock would be zero, 

I would definitely do a compression, leak down & squish test,  if you had a hole in your piston!

If You still have your clutch cover off, do a leak down with cover off. To check for leaks @ keyway
