Title: Lancer can you help me out?
Post by RanDaMan on 07/12/12 at 14:08:16

I only asked lancer by name because ive come to read he is the man to talk to about carbs and jetting! but if anyone else can help me dont hesitate to reply! Thanks in advance. :)

Mods that i have ordered parts for are:
-Dyna exhaust with stock baffles (might drill the 1/2" hole if highly recommended)
-k&n air filter mod (removing the air box)
-raptor petcock

I intend on trimming the carb diapragm spring to eliminate the shut down afterfire (dont know if this affects jetting or not? :-? )
and i want to do the white spacer mod while im at it.

I live rouhgly 630 ft above sea level.

Could anyone help me out with good starting points for the required jets? assuming ill need new main and pilot jets. would i need to change any others?

ANY HELP WOULD BE VERY MUCH APPRECIATED!!

thanks again :)

Do yourself a favor... Do one mod at a time.

I would do the exhaust and intake at the same time, but don't do all the carb mod's at once or you won't know what needs tweaking.

get the jets right 1st, then the white spacer, then the TEV.

And I would suggest, you add a washer to the TEV 1st before trimming. That mod is reversable, trimming isn't.

I learned the hard way not to touch that TEV spring. :-[ Just make sure the diaphragm and passageway are clean. For your mods a 1/4 spacer, (or one #4 washer), 155 main jet, and maybe a 55 pilot would work. Jetting is trial and error, but that is where I would start.

One jet at a time; pilot jet and then the main jet; after that work the needle.
I like using washers on the needle better than cutting/filing the white spacer; more options without burning bridges.
Work your way up from small to large jet sizes unless you know pretty much where you are going with it already.

Alright good to know! I know ive got a decent amount of work ahead of me and its all new to me. so i really appreciate everyones help! :)

and vers1 how would adding a spacer help me with that mod? i thought the point was to relieve some of the spring compression not add to it?? :-? . . . might not even do that mod but its something id serioiusly consider if its the only way to rid the shut down after fire.

Theres more than one way to skin that cat, you can use the clutch & first gear with the kill switch, IDK if pulling the choke would help,, it mite, mite make it worserer,, IDK,, something to try,,

Yeah someone mentioned that technique to me and i tried it but it wasnt effective. maybe i just needed to let out a little more on the clutch? should i be almost reaching a stall point before i hit the kill switch?

LOad it till youre in "the friction zone", hit the kill & let off on the clutch, maybe a higher gear would have less of a tendency to make the bike move, mite wanna hold the brake,, Dont let anyone video it! :)

Change your muffler and air filter (for whatever reason?) then see if you actually have a problem to solve first? In other words, don't put the cart before the horse. The future problems you MAY have, all have symptoms, but right now you don't know what they are since they haven't occurred yet.

I've got a dyna muffler and a K&N filter on the way! I def need to change the air filter though I went to change the oil the other day and i unplugged the "puke" line that comes from the air filter box and some oil came out I'm assuming theres a little oil on the stock filter because of it.
