these are some pics of the bike as it was, will have to post some of what it looks like currently and more once I have finished modding it.

TeamCheap: What exactly is rejetting? (must excuse me have only been riding for about 4 months now +- 13000km's on the ZSM 1000 +- on a F650GS and a few hundred on various sports bikes)

Where exactly do you put the air filter? I don't see any obvious place to put it on the ZSM

You have to remove the complete stock airbox from the bike which will most likely take up a lot of space.It will be under the seat and attached to the carb with a fat tube.

I removed the stock airbox and was glad I did since I seen just how poorly it was made after I got it off.
It had gaps in the box after the filter which meant dirt could have gotten into the engine.

So with the stock airbox off the bike I started measuring up the space I had in the frame and had to allow for the battery which I was planning on moving but there was a lot of space and the K&N air filter I chose fit very good and just attaches to the carburater itself.


With an after market airfilter the bike ran a bit better but I didnt HAVE to rejet it until after I put the freeing flowing aftermarket exhaust pipe on.

With the free flowing airfilter and exhaust pipe the engine is flowing a bit more air thru the carb/engine which will cause a lean running condition which gets corrected by changing the main jets in the carb that meter the fuel.
So rejetting is simply changing out the carbs main jet to one closer suited to the engines needs.Mine came stock with a 98 and if I remember correctly I stopped at a 115 but still feel a 117.5 would be better.

It most definitely had a large impact on my bike that was easily noticable while riding.
Before the changes I could hardly get the bike to start off in the deep sand it would bog and stall at times and it was a handful to control until it got some speed but after the mods and rejetting the thing was like a different bike in that it would just take off in the sand and excellerate and was much more controllable because of the power it has to get thru the sand easily.

Even with the mods it is still just a 200cc engine and can only be expected to do so much but there is a bit of room for added performance.

Dont ask me how it impacted my fuel economy I DONT CARE.

Here is a picture of my 250x-2-300ex frankenATV.

Had not actually considered that I can get rid of the air box, will make more space for the fuel tank :D

is the 98 stock a setting or an actual piece of hardware? could you give me a picture of it or maybe an idea of where you can get one

The jet is an actual piece of hardware that installs into your carburetor. It screws into place. Take the old one out, put the new one in! These can be changed after the carb has been removed from the bike. Space is tight on these smaller bikes. Your Sierra, like my X-Ranger has a Mikuni carb. This is a Japanese carburetor which is a great upgrade over the Chinese carburetors that come on most of the chinabikes. You got your Mikuni straight from the factory. Very cool! The carb should have both a main jet and a slow jet depending on the configuration. That's just a guess by the way, don't quote me on it! The carb will also have various screw adjustments on the outside of the carb. Be careful not to screw with them http://s3.amazonaws.com/advrider/lol8.gif unless you get some reliable information on what to do.

Below is a picture and a link for one of the better dealers of these parts. You may be able to do an ebay search and find what you need.

Hope this helps!

Yea thanks very much :D

oh I got a price on the HID light kits, they are like R 1680 (South African rands so say like 247 USD)

Had a chat to the trail tech guys and they can fit the bike with all of the features working to the bike, though am debating if I really need a temperature gauge and rpm counter as the bike hasn't got any as it is.

also managed to source a fuel warning light system from Yamaha, so will grab one when I build the fuel tank

Take a look at these carbs and let me know what you think

my carb has a logo stamped on it with the letters "TK" in a bike circle so not sure what make it is

Bike without the tank and mud guard as it is currently (have changed to road tires though)

I was thinking about buying one of these and installing a lifan pit bike motor like a 140cc.

Go for it I think that would be a very fun project also.

That one is only a couple hours away and I have a co-worker that is from there with a truck. I may see if he wants to pick it up for me.

I think with a 140cc lifan that it might be a good commuter toy. I can always part it out.

Sam, You should think about a ghost camo job (black, gray, white) I did this to a competition compound bow a few years ago, very easy and with the flat black of your bike it wouldn't take much. If you are interested I can try to get some pics of the bow. By the way how are you healing?

Driller, I'm leaning towards the camo sticker kit. It's going to cost me around $150. It's an easy process to cut a stick the material onto the bike. They cover ATVs with this stuff all the time.

I've been out of the sling for a week or so. I'm basically back to normal now. The shoulder still hurts a lot but I've milked it about as much as I can. I've been riding motorcycles for the past two weeks. Thanks for asking! I appreicate the concern.

jdnva, that is one HUGE picture.

Do ya think maybe you could downsize it a bit please.

I guess my project will be to buy a brand new Lifan and then take it apart and put it back together with locktite and lock washers.
also tape up electrical stuff. i am going to think of it sort of like building a model. :)
