that's what made me kinda mad is that the lever gets no leverage because of how short it is but i think i'm gonna try to get a z400 clutch lever and see if it fits...

 

I am still trying to get it tuned in. It's hard to tell when it is running rich or lean, because if it's too rich, it spits black smoke and backfires, and if it's too lean it spits black smoke and it backfires.

I did discover a nice but potentially dangerous way to tell if it is running too lean though. I can close my garage door (just for a minute) and with my Ozark warmed up, get on the gas in nuetral and watch the head pipe. If it starts to get a red tint to it, it's running too lean. I definately can't do this when I get the turbo on!!!

I went with 1 1/2" PVC pipe to make the snorkel. I can't really go any bigger due to space limitations. However, I am convinced that this is plenty big enough. I am thinking this because most of the big cc 4X4 quads run a 2" pipe for thier snorkel accept for the really big big ones.


Here are a couple of pics of the lights and the snorkel...........

Holy crap, them things are humongo...I like the p.v.c.. Well done!

 

Yes, they are a bit on the big side! I was tired of riding at night and having to go REAL slow due to the stock headlights not putting out adequate lighting. Thanx!!



Well, come to find out, the snorkel setup was making the motor run lean, not rich!! I ended up going from a 136 jet to a 138 jet. Unfourtunately, this is the biggest jet that came in the DynoJet jet kit. I'm gonna have to order larger ones directly from DynoJet if I add anything else.

To give you guys an idea how much larger this jet is than stock, the stock jet size at this altitude was a 128. DynoJet recomends using a 134 jet when a high flow pipe and a high flow air filter is used. I had to run a 136 instead. Now, with the snorkel, I had to change it out even bigger to the 138.

After the ride at the end of this month, I will have all kinds of stuff to let you guys know about!



Ohh, I also added an 8" fan to the motor today. I am going to do a LOT of idling on my next ride, and since this is an air cooled motor, I decided to either plumb in an oil cooler or to get an aftermarket fan to blow air over the motor. I decided on the later. This fan pulls a maximum of 5 amps when running (but it takes closer to 10 amps to get it up and running), and it blows 500 cfm if I remember right. I have it installed in front of the motor, between the motor and the frame. I have an on/off switch for it and a master on/off switch under the seat that controls power for the winch, stereo, and the fan. I have a thermostat controller that I might be adding to it later down the road, but I would prefer to get the oil cooler plumbed in and use the fan on the oil cooler. I just don't know where to tie the lines in to.

 

maybe i need to go up on my jetting. I have a 138 in mine with a cam, ported head, header, yoshi pipe, open air box and uni filter. hmmmm. i thought the plug looked a lil white. Anyway, I need everyones help....I talked to PRO-COM today, the maker of most aftermarket REV boxes. They said id they received at least 20 call on a cdi box they would start making it. I told her I'd have everybody interested call. Her name is Jennifer, she can be reached @ 1-949-837-8183. A rev box could probably benefit all bikes as it changes the timing curve and makes it more aggressive. If everyone could give her a call and anyone you know with a Z250 wanting to hop it up give her a call. They usually charge less than 100 bucks for thier rev boxes through Alba Action. I put my manual clutch on tonight, It seems like it'll work fine but I do have a few complaints, As i stated before, the lever is too short, 4" compared to 7" for the stock brake lever. Looks kinda funny compared to the front brake lever. It is pretty hard to pull compared to a 400ex. They could have made the hyd. line going to the engine a lil shorter. I had to do some creative engineering to retain the parking brake. The fitting that sticks out the clutch cover sticks out to far, seems like it might tear up my shoe. While I was at it, I trimmed the front fenders by about 4". Looks more aggressive. The bike looks a lil longer and more sporty.

 

LTZGUY i will call them and also i thought that the line was at a fine length...if you bleed it right it is easy to pull but i am gonna try to get a lever to see if i can fit one...

 

Well i got to ride it today and it worked pretty well. my friend told me i need to drain the fluid out and use trans fluid and it will be smoother. I can now tell even more how much the clutch is slipping. I looked in my manual on how to change the clutch plates and it looks to be a major PITA! i'm not looking forward to doing it. I'm gonna pull the front plastics off and try to route the hyd. line better to look more factory.

 

LTZGUY, in your nessing around with the motor, have you discovered where to tap lines into for an oil cooler?

 

well you could take the screw out where the oil filter is and hook a line to it then drain it back into the timing mark bolt, left side of motor, top front of the side cover. You would have to mount your oil cooler slightly higher than the return line so it will drain quickly. I would try to ask a mechanic or parts guy if catching oil there will be safe as i have not tried it yet. I will tell you this, if you put an oil cooler on an air cooled motor you might be shooting yourself in the foot.....it is designed to run hotter and if you cool the oil you could accelerate the piston to bore wear. The engine won't get to its designed temp and won't expant like it should. I would recommend just a cooling fan. I have noticed my bike is faster the hotter it is andit is slower if i have the fan on for a while. The only time i use the fan now is when the bike idles for long periods (like the way it sounds, lol) or when i'm trail riding with a slow group of people on a hot day. I put my clutches in tonight and it grabs much harder, seems to shift smoother. haven't reallt got to ride it yet, but i can't tell a big difference already. I power braked it and it just pushed the front tires while they were locked up even with me leaning way over the handle bars. I hope everyone on here has called pro-com so we can make them get the ball rolling. I guess the next thing i'm gonna do is a carb. I talked to a friend of mine who has a 450r older model and he put the newer model 450r carb on his and he said it was like night and day. not saying i'm gonna use a 450 carb, but just using that as an example of the difference a carb will make. Kinda like doin a bunch of crap to a v8 engine and leaving the stock carb on. Can't wait!

 

LTZGUY what kind of carb are you looking for? you might be sacraficing a lot of bottom end by going too big
