[evil 525]

ok I bought the hotcams cam. I guess now the question is how big is the gain and how hard is this to do. I can adjust the valves easy enough. but as far as switching cams out I have never done this. have any of you guys?. plus is there a walk through on this somewhere.
thanks

You will need to "break" the cam chain since there is no master link. It requires a special tool to break it and put it back together and the tool isn't cheap, especially if you use it one time! I think they are $80-$100 for a quality tool.... Might want to check to see how much it will cost to have done at a reputable mechanic so that you don't have to buy all of the stuff.

[evil 525]

can I use any chain break tool? or is there a special one for small cam chains. any one else rnning a aftermarket cam? good gains?

http://www.motionpro.com/motorcycle/tools/view/chain_breaker_and_riveting_tool/ You need a chain press this is the lowest price one, KTM tool goes for around $150

[evil 525]

I have been looking on ebay for one but not sure if any of thoes motion pro ones are the right ones. does anyone know if any of the ones curently up on ebay will work?
thanks

[Groves187]

I would give motion pro a call and ask them if it would work so you dont get the wrong info.

I got a chain break tool on ebay for 40$. Its actually for motorcycle cam chains, I called the company they said it will def work. if any one else is looking for one its on ebay has a red case and a buy-it-now for 50$. I got mine cheaper because I actually bid on it. when I put in my cam I will post back and let you guys know how it went.:D :D

[evil 525]

ok guys I've run into another problem. I have to break the cam chain and I now have a riviting and breaking tool. but where do I get the rivet links to put the chain back together???
please help

[OutlawBill]

any good Polaris or KTM dealer should have one for about $8.00

[evil 525]

outlawbill
you've been a big help to me in my quest for performance parts
THANK YOU

[evil 525]

nobody around here has the cam chain rivit links I need. can you reuse the rivets? pretty sure I know the answer to this one though.

[OutlawBill]

no order from on line store.

[evil 525]

ok got them, I had to drive an hour away but I got them.
doing this on sunday ill post then.

[evil 525]

question
do you have to rejet when you put a performance cam in?

[evil 525]

its all together and it runs good but it seems extremely lean. my front pipes are glowing red about a foot down.it sounds crackly(if that is a word) and when I let off the gas I back fires pretty good. are you spposed to rejet after caming something?.

[sheriff525]

I would have to say it would be a good idea to the re-jet!
your changing the fuel consumption and therefore you may need to go up or notch or two on your needle (I think).
What are you running now?

[evil 525]

ap timing .100. leak jet pluged. stock pilot jet . blue jd jetting needle. 170 main jet. air fuel screw 2 turns out.

[sheriff525]

What clip is your needle on and maybe turn your fuel screw to 1 turn out (that will richen the mixture a bit) Sounds like your on top of your settings. Whats your elevation?

[suprdavtn]

hot cams only has one cam for the 525 and it is top end only. the web cam has 2 for monster low and mid range gains.

[evil 525]

my elevation is 700 to 800. I put my main jet up to 180. and my pilot jet to 48 now. I have to take it out and try it again. the cam gave me really good mid range.

[evil 525]

ok so right now I'm at 175 main jet, 45 pilot(stock) blue needle 3rd clip(might try red needle on 4th clip) fuel screw 2 turns out. now for my AP timing I did it a little diifferent I took the air filter off and kept hitting the throttle and adjusting the AP screw until the fuel spray just missed the slide.
ok my report
well right off I noticed that the bottom end lost a little (just a little) and let's face it with mods there is almost too much bottom. still wheelies really easy. but the miidrange to high is where it shines the hit is intence. very very strong mid and high. I was only in a small sand pit so I only got into high rpms in second and low rpms iin third but man does it pull.
so my verdect. I'm very happy and if your willing to give up a little low end (remember just a little) and get a bunch of mid and high. than this upgrade is for you.

[SSJEFF]

Youy might lean out the screw and regain you low end. If you screw is rich then it will affect the initial hit. You did the AP correct. I should do mine that away but I did not notice you could see it that easily.

"What clip is your needle on and maybe turn your fuel screw to 1 turn out (that will richen the mixture a bit) Sounds like your on top of your settings. Whats your elevation?"

From everything I have read, screwin the mixture screw in leans it out. I have mine set at 1 turn out. The 2 stroke carbs richen when turned in. If you can find literature to correct me then I would like to see it so I can get my threads right on predatorowners.com.

P.S. If your pipes are glowing red then you are really really lean. The piston is probably glowing red also.

[sheriff525]

not sure where i saw it but i learned the tighter the air screw the richer it gets....I will look into it later.

[sheriff525]

by the way awesome gains! what was your costs on the cam?

[evil 525]

I paid 160 for mine but I know you can get them on ebay for 130 pretty easy. as for the fuelscrew I checked the service manuel and of coarse nothing in there. I'm 90% sure turning it clockwise leans it counterclockwise adds fuel.

OK, I found info on Keihins web site.

http://www.keihin-us.com/am/_media/pdf/slide_valve.pdf

It is in the idle section and out is rich, in is lean. It is good reading though if you need to figure this carb out.

[sheriff525]

ahhh....that explains alot! thanks

[525 Outlaw Dude]

Got the cam broke in and i cant really tell what the gains really were, besides alittle better pull on top i think, i kinda got confused because is wont allow me to pull the front end up for wheelies unless i really try and it feels sluggish on bottom end, is a 158 main jet fine with these mods (ct pipe, cam, K&n??? I think im going to drop a tooth and see in getting a 12:5.1 piston to gain bottom end back? if anybody else has the cam give me your feedback of what you thought and if anybody knows anything else to gain bottom end?
Thanks Adam

[SSJEFF]

That seems lean to me.

[sheriff525]

Where on ebay did you see these cams? Also someone was saying web cams has a couple of cams for the outlaw 525. I couldn't find them. Any help. I want one that is mainly bottom to mid.


Outlaw dude - I agree with jeff your bike sounds too lean.

[evil 525]

alright second report
not good
I finally got out to a much bigger sand pit. first thng I noticed is the the low end loss Is worse than I thought couldn't tell the first time out the pit was too small. its bad enough that I took the cam back out and yes my jetting was spot on. if you are going to cam get a big bore kit as well. I wasted money doing this mod.
hopefully this helps you guys.

[SSJEFF]

I hear the KTM 833 is the cam to use for low end. It brings the power down lower and makes the engine rev snappier.

[bad_on_black525]

Man Evil I am real bummed for you bro. I can't believe you went through all that just to rip it back out.

[525 Outlaw Dude]

got the 525 back and the guys at the OutDoor Toy Store said i broke it in great, took the 14tooth front out and switched it with a 13tooth and the power with the cam, ct pipe, K&N, and 13tooth work great, the only thing is i have to take 1-2 links out of the chain because its real loose and it fells great all around but i think when i go to the dunes im going to put in a 15tooth for more spead :p

[evil 525]

bad-on-black525
tell me about it wasted a lot of money and and 15-20 hours of my life. just got the stock cam back in an hour ago man I love that bottom end. live and learn guess. I lived it you guys learned from it. you get your going yet?

[bad_on_black525]

Yeah man I got my outlaw back and I bought a new RMZ 250 2 weeks ago and last weekend Greg and I went out in the woods and I sucked some water into my motor so now my RMZ is getting rebuilt after 5 hours of riding.
