Title: Another Noob Question-White Spacer
Post by Tiefighterpilot on 05/19/10 at 22:14:36

I see lots of references to white spacer mod.

Is this the same spacer that is in Lancers Jetkit? Why is the mod called White Spacer? only 1 white spacer in carb?

Sorry, I am about to rejet this weekend, and getting nervous.

Maybe cuz its white ? ;D
I'm not familiar w/ the jet kit, but I do know that trimming the white spacer, will raise the main metering rod in the main jet, which in turn richens the fuel delivery at 1/4 to 1/2 throttle range,......and possibly the entire range ?

Lancer's Jetkit includes 4 washers (I think there are 4) that you use to replace the stock plastic spacer (that happens to be white). there is only one white space in the carb.

Lancer supplies you with 4 washers so that you can easily change the size. so you can just remove a washer instead of sanding down the plastic white spacer.

i'm not 100% on this, but i'm pretty sure the mod affects the 1/8th to 3/4 open throttle range.

I haven't done the mod yet myself (though i've done 2-3 rejets) as the washers didn't fit just right when i got them :(.

check out this post:

it isn't our carb, but pretty darn close. the tuning should be exactly the same.

there are tons of carb related posts on the site, just have a look around!

Ace Hardware has a #4 nylon spacer that as near as I can tell is about 1/2 to 2/3 the size of stock. I got a jet kit from Lancer and haven't used the metal washers because the spacer mod was the first thing I did. I'm a mile high (which makes me run richer) so I don't know that I even needed to go with the spacer mod. Since I have a pretty open pipe and K&N drop in filter I'm probably just fine.
Don't get nervous...just go slow and learn about your bike.

so can i access the white spacer from bottom of the carb? Where is this spacer... anyone with picture of it?

Thanks.

I can't remember if you get it from the top or the bottom, but i guarantee you won't mistake it for something else.

it's the only white disc on a large ~4" needle.

BurnPgh helped me take with it a while ago and now i can't remember...

Thank you... i hope i can get to it from bottom. I am not planing on taking the carb off the bike.

Sorry, you get at it from the top !
Its #4 in the view. For just the spacer mod, all you have to do is take the tank off,......and the top of the carb.

Thanks!!!! so just take tank off... spacer mod.

Drop bowl... rejet.

Perfect. Sounds quick and easy. I really want to ride... have so much to work on this weekend (remounting the muffler and taking off the stuff not needed and getting ready to go bobber soon)

Title: Re: Another Noob Question-White Spacer
Post by Routy on 05/21/10 at 06:25:04

But, let me caution you, (this IMO only) don't.....I repeat, don't just start start throwin mods and jets at your carb,.....w/o some evidence that it needs them. More than one person here has not had the best results from moding/jetting unnecessarily.

In my case, I had a perfect idle, and very good throttle response thru the entire range. But I was running a ragged low end 1/8 to 1/3.....light load throttle,....so much so that it ran much better w/ the choke out on 1 click. The spacer mod only, corrected that problem to near perfect, and also shortened choke time when cold.

Thanks. I am having major popping and low end throttle response after upgrading to HD muffler. I really appreciate your warning.

By the way, can the spacer mod be done with tank still on the bike? Maybe lifted/moved a little?

Title: Re: Another Noob Question-White Spacer

if I remember correctly - remove the throttle cable, fuel line and vent hoses. Loosen the flange(s) and turn it clockwise. Then you can access four screws on the top.

Mine runs great and pulls all the way,Went one jet up on pilot jet and 2 jet sizes up on high speed. Left the spacer stock.Just have to drop the fuel bowl to get at them.I have stock muffler with 1/2 hole drilled up in the center,not much louder and doesn't sound good.

I got to my spacer by just removing the seat. I had access to the 4 screws on the top of the carb right there. Replace those screws (for real) the heads strip really easily. Also once you pull the diaphram out be super duper careful when you start on the little bity screws down in there (that's how you get to the spacer). On mine one came out and the other stripped right away. I managed to get it off after my panic attack but replaced it with some little PC hard drive screws that (miracles of miracles) happened to fit.
Remember go slow with carb mods. If you really want to ride then ride and wait for a crummy day to do it.

1st time you'll want to pull the carb, but it can be done.
try twisting the carb to the side, but do remove the hoses and cables.

Be sure that you don't have any exhaust leaks first and your idle is set high enough. After swapping my muffler to a HD, I found I had a small leak and the joint between the header and the muffler. After a beer so I could make a shim it was better, but at that point I had read more about being able to rotate the header slightly to change the angle. After I did that it was popping like crazy so I knew I had a head to header leak. Once I got that tightened down right my popping almost entirely dissappeared without a re-jet of any kind!

I may still need to re-jet but that's after I do the other roll-on tests and such to determine what is truly needed in my application since each one seems to be different.

Good luck, and let us know what combination works for you! 8-)

Most of my popping on decel was eliminated by increasing the idle slightly (the thumbscrew) after I was sure that there were no more exhaust leaks (even the smallest leak causes some popping) 8-)

That is one spot where you don't get 1/2 azzed w/ a screwdriver. If you don't have one that fits, you better not even think about it. And even if you do, you better have some body weight to add to it all too. If I remember right, it isn't the best place to use an impact driver either :o

Title: Re: Another Noob Question-White Spacer
Post by LANCER on 05/23/10 at 07:47:54

I do use a small impact driver for these tiny screws and the long slim phillips head that comes with the driver is a perfect fit for the screws.
I set the slide on the top of a vise with the jaws just sligthly open for the needle to go down through, then while holding the slide firmly with my little and ring fingers, and holding the driver with thumb, fore and middle fingers I gently but firmly tap the driver. The screw usually come loose on the 1st or 2nd strike.

I got the little impact driver at the Harbor Freight store for less than $10

7 Piece Reversible Impact Driver Set
Item # 93481

(1) .
Only:$5.99

The larger but shorter phillips head works well for the top cover screws and float bowl screws. The driver saves time and a lot of FRUSTRATION when dealing with the "less than top quality" stock screws.

I learned a little trick for putting the two little screws back in. The spring makes replacing the screws almost a 2 man job, but if you open the vise a little and pull down on the needle. Then when the spring is compressed tighten the vise so the the spring stays depressed. You can then use 2 hands to replace the screws. Make sure the vise jaws are protected with something soft to protect the needle. :)

Post by Routy on 05/23/10 at 13:22:14

From Lancer's pic, that looks like a smaller driver then the standard one I have, which takes a "too heavy" strike to use on carbs.
I really didn't know they made one that small.

Thanks
