engine break in

[heatlbj6]

i just recently installe my kor top end and im going to do the engine break in this weekend but im wondering what jet size to run i have a pro circuit exhaust and v force 4 and since im doing a break in i wont be able to do a plug chop to confirm the jetting any suggestions ?

Probably 310 should be good at least for heat cycles. Lots depends on YOUR break in process, opinions differ greatly. Couple different break in processes listed somewhere here. General? Not in engine section, I looked.

 

[heatlbj6]

so i should be safe with a 310 with out doing a plug chop ?

 

[Larry's Shee]

Don't know all your mods, as I said, heat cycles.

If you have something larger, throw that in. Better fat than fried, plugs are cheaper than pistons. List all your current mods.

pro circuit exhaust v force 4s air lid on stock carb port and polish re chambered head

The CT break-in process is a VERY GOOD read.

 

[heatlbj6]

do you possibly no where i could find that ?

 

[Larry's Shee]

Add for weather, 320, maybe 330 after first couple heat cycles and you actually start to ride it. Click the linc and read the CT breakin procedure.

 

[Larry's Shee]

clic linc in previous post, has linc to C T

 

[heatlbj6]

i dont see a link anywhere

 

[heatlbj6]

oh nvm sorry
so you think 330 for engine break in with mods but its gonna be like 50 here in ct this weekend

yep /\/\/\ that, might as well use the procedure given by your engine builder !!!!I:I

your main jet has nothing to do with heat cycles or break-in, as you should never be holding it wide open, and thats the only time your main jet comes into play....past 3/4 throttle.
heat cycles should be lightly revving it maybe past 1/2 throttle.
you're just bringing it up to normal operating temps a few times, allowing it to cool between them, then retorque the head and base nuts.
initial break-in (if you decide to do that ?) involves riding it for a little while without any long sustained WOT runs.
most of us do heat cycles, take it easy for a ride or 2, then let 'er rip.
i'd throw a 290/300 in there for heat cycles and to start plug chops, then work whetever direction the plug chop color suggests.

thank you im gonna do a leak test this weekend then begin the heat cycles its gonna be kinda hard not to ride hard on it since i havent rode it yet with all these new mods

 

[heatlbj6]

also everyone says my tires are on backwards and there only on like that cause the air plug is on the outside and if i flip them around itll be on the inside

The rubber has been fitted incorrectly, you will find a directional arrow.

Whoever fitted them needs to go back to school, for more tuition.

 

[heatlbj6]

so i should just flip them the correct way and leave it how it is

 

[Larry's Shee]

Just swap them side to side, left on right, right on left
