Gaff,

Why do you get kicked off when you mention "His" name? Also I am planning on getting an IDS2 for my Mojave next week, along with 20 inch rears. What jetting setup do you reccomend? (I am getting the K&N jet kit) I already have 13/43 gearing, and was told to go to 13/40, but I can't find a 40 tooth rear sproket, only a 41. Any ideas what my top speed will be with 13/41? Thanks in advance.

 

13/41 gearing is the way to go on the Mojave as well. I just did it this summer and boy do I wish I would have done it 2 years ago. I don't think the 40t is available.

 

This is funny.
I just wrote a reply again and mentioned "HIS" name, and once again I was off.
I was writing to tell you it was a coinsidence and it wouldn't take the post.
It's common practice to change the front sprocket by one tooth and the rear by two. In knowing this, this would lead me to believe that thier probably is'nt a 40T rear for the mojave.
Now minipulating gearing by changing tire sizes can get you were you want. But from all the moj riders a 13/41 seems to be the set up.
As far as jetting goe's, follow the instructions, they will get you rite in thier quick. The most common proplem with jetting is, the instructions will tell you to put a smaller main in to match your mods or altittude and some poeple will, well it's hard to help your self, you always wan't to go with the bigger one. Almost always these poeple will want to re-jet.
Wich once you do it your self it's pretty easy.
I always try to get poeple to do it them selves, or I'll have them with me while I'm doing it.
Lets face it, what ever you ride or drive, the exhaust, jetting, and air filter is your big jump in horse power. After that tuning the mods in some times can be the next biggest jump, and knowing how to set and tune carbs is your best way to keep within top performance of your machine

 

Do I really need another filter? I don't want a K&N because of the costs, and I ride in dusty conditions a lot. Is a UNI or TWIN AIR really that much of an improvement over stock? Also, will the top speed be any higher with 13/41 and 20 inch rears? Thanks.

 

gaff, i put the ids2, jet kit, and k&n on 11/2 years ago and havnt messed with it since. i just added the 13t sproket and the machine is quicker. you said that you turned the air mixture out 3 and one half turns. my problem is i cant find the instructions from the jet kit so i dont remember where the mixture screw is located. im thinking its on the bottom of the float (outside the carb) is this right. or can you tell me where its at.


thanx bill

 

kawi250,
I can't comment on the other filters, I've always used the K&N.
I can tell you I road in new orleans this week end it was as dusty as I've ever ridden in. I cleaned the air filter today and found no dust or water ressadue on the carb side of the filter.
When I had the stack filter in, I always found dust and water on the carb side of the filter.
Also, The smaller the tires the lower the gearing in turn lowers the top speed.

vlucdog,
The instructions say, screw the air/fuel mixture all the way in and then back out two and a half turns. I experienced some back firing while coming off the throttle, so I turned the air/fuel mixture screw out one more turn (three and a half turns total) this cured my back firing.
The air/fuel mixture screw is under the carb. If you losen the hose clamps on both sides of the carb, then twist it side ways, you will find it on the bottom forward side of the carb.
If you sit on the bike, try to do this from your left hand side. But if you didn't reverse your hose clamps when you installed the pipe the screw heads are on the right.
The reason to reverse the hose clamps on the carb is that you have to let the header cool completely or you will burn your self on the header

 

Gaff, I have changed my sprockett to a 13T and my jet to a 134 dynojet. This thing is awsome. I was wondering if the exhaust makes that big of a diff. Is t worth spending the $200 or not. I live in Panama City Fla. pretty close to LA. why are you running a 138 jet, I guess it's probably because of the exhaust. I also drilled holes in my snorkel by the handle bars. So what do you think, outrun a 300 ex? Banshee?

Thanks.

coyeverage,

I remember you put the jet kit in, did you put a filter in as well?

I see you are using a dj-134 main, this does not seem rite, but could be.
Most who get the filter and pipe (with eight disc installed) can only use the dj-134.
With your set up my opinion would be that the dj-128, with the needle c-clip on the second slot would be a close set up.
But I can't be sure.
Go to www.atvnews.com/output.cfm?id=33463, thiers an article about carbs and some good ways to see if you are running lean or rich. (if that link doesn't work, go to atvnews.com, click on tech, then read the article: the power of sience)

I only say this because thier may be more you can gain out of your jet kit!!

The IDS2 is well worth the money, and with a filter and jetting you will love it. Not to mention an awsome sound.

As I mentioned most can only go up to a dj-134 jet size (with eight disk in the IDS2) I attribute myself being able to go as far as a dj-138 because I drilled a couple of holes in my air box lid and removed the snorkle cap off of my air intake.
I also used twelve disc in my IDS2.
Now I believe if I possibly went to eight disk and a dj-134 main I may have a little more bottom end. But I started with all twelve disk and a dj-138 and expected to be rich, then start jetting down, but so far it proves to be nearly perfect.
I have been enjoying the hell out of it and just reading the spark plug and intend on going to do the test on the link I just posted.

Also keep up with your valve adjustments, this to can rob a little performance

I can power shift into second and wheelie very easily. Also on the trails second will lift the front end easly, in third a little, I mean very little assistance from a root or bump will carry the front pretty far.
And sence you have the 13T sprocket you know how much faster second and third are

 

[img]i/expressions/face-icon-small-cool.gif[/img] Gaff, Thanks for the reply. No I do not have an after market filter on the Lakota. I put the 134 jet in because thats what the kit said, what should I do?

 

First read your plug! probably good and black.....clean it

I would suggest, putting the c-clip on the needles second from the top slot.

Then install the dj-128 nain jet.

This all can be done by just loosening the carbs hose clamps and rotating the carb side ways to do the change. (ten min job)
Insure the air/fuel mixture screw is two and a half turns out.

Go to the site I posted earlier and start testing to see if your rich or lean.

To much jetting can rob you of valuable power and throttle response.
I noticed when my bike was stalk I was running a little lean, so I believe the dj-128 will work.

Just check it out, the main thing a jet kit gives you is better throttle response, I believe you will notice a difference this time.

A little better throttle response will sling the 13T sprocket better.

Good luck, and post any problems....I'm sure you will get it.
