Cam Install

Can someone pleas scan some the pages out of the manual where it shows how to install the cams. I bought my bike early this year from a bud and I think he is off a tooth on his install. I have a book but I lent it out and I have the whole ehing tore apart and I am not sure how to Check the cams position. It seems like there are multiple aligning marks on the cam. I took it in to dyno it and It only made 98hp. But the real kicker was that it peaked around 9500rpm.

please help

You really need the book for that. You could have had a bad fuel pump, spark plugs, fuel strainer, pinched hose, etc., as to why you peaked at 9,500rpm. If you were off on the cam timing you would know it. There'd be no guessing about it.

What would make the bike not idle for chit until 190 deg? My bike will not idle until it is warm. than it runs decent. So it doesn'r idle and its power cureve is way off. Whats your idea?

Replaced
throttle bodies,
fuel injectors,
fuel rails,
fuel lines
fuel pump/tank,
spark plugs

Did you replace the TB's with a used set? If so, that the most likely culprit.

yes they were used. but it ran the exact same as the pair I had. I guess it could be the problem but I dont know of anyone willing to let me disect their rr to figure it out.

Did you try a compression test before you tore it all apart?

No I couldn't get the compression tester down the hole with the valve cover on. I will try now that I have the cover off. Maybe the rings are in the wrong position and I am geting blow by or something. It is a 03 with a micron slip-on PCIII slightly ported head. I didn't do the work and I bought it in pieces for $4k I put it togeher and this is what I got. I still dont think it was a bad deal because I went in knowing that it may not run. I figure I could always go ebaying and get a new/used engine for about $750-$1000.

I will jump the starter with the battery to test it.

If it runs like crap til warm it could be the valve clearances are off, especially if your buddy had the cams out.

It would be best if you could get the engine warmed up before you run the compression test to get an accurate reading and remember to hold the throttle wide open while cranking it over.

that could be the problem because he was messing with the shims. thanks for the help. I will keep an update.... What is the thread size of the spark plug hole? so I make sure to find a tester with that thread.

I just talked to the guy who ran the dyno on the bike and he realy seems to think that it is of a tooth on the cam gears. because it starts right up but then it stalls then it runs when at temp this is why he thinks that it is not shims or any thing. I am just going to check compression and the timing.

You might as well check your valve clearances while you're in there. How many miles are on the bike? I don't see where one tooth on the cam gear could cause it to jump time. Maybe several teeth missing. I'm leaning with RLS, towards the head or the TB's.

If it has a PCIII, maybe try another map. or remove it altogether and run it.
I have 28k on my 03 and only 2 of the exhaust shims were off by a thou.
The manual was on this site, maybe a search?
When you do a valve check, in the procedure you start with the crank mark (T) lined up with the index mark. When you have this mark lined up the camchain top gears should have (IN) mark on the intake side of the intake gear and (EX) on the exhaust side of the exhaust cam.
If the marks are on the inside of the sprockets, Turn over 360 degrees.
If these marks align up, then I would think that the chain hasn't skipped or been installed wrong and the cams should be right.
I don't think you can put the intake cam in the exhaust cams position due to the fact the cam pulse generator bolts to the other end of the exhaust cam.
Let us know how you make out.

I will do my best. I found a head for $100 bucks and I am half tempted to buy it. The only problem is that I am about broke and Christmas is coming and I need to save.

I wouldn't buy anything until you figure out what the problem is. Did you ever wonder why this guy is messing with the shims at 2,500 miles? Mine didn't need any shims at 17k.

he was going to take it to the track. He replaced the shims with better tighter shims and when he put it back togather it didnt run. so he took them out and put the old ones in. he also did some other work to it. But any ways it turnns out that someone had put water in his gas and he dind't know it until after he too them out. It is a huge long story. Then I bought it in pieces.

also it only had 1.5K on it when i got it. lol

How the heck do you get water into a locked gas tank?

Sounds like the previous owner didn't have a clue but thought he did.

They do say a little knowledge is a dangerous thing.

You're going to have to check everything in there to see what else he tried to 'improve'

Valve clearances would be high on my list for sure, the odds are he didn't make notes of the position of the original shims, if he knew how to do the clearances he wouldn't have put shims in that it wouldn't run with.

It didn't run because there was water in the gas. and yes A little knowledge is a dangerous thing.


I took a compression test (cold engine) and the compressions are all f'ed up. 1 has 128psi and one had 97psi. I dont recal what the other ones were but I have it written down at home. I think that this is a problem. I did to cold so I don't know how much of a difference that will make. I am sure 30psi is a little much. So This weekend I will put it back to running order and warm it up and do the check.

Yeah 30 psi difference is a lot and even cold they should still be fairly even. I would think you should still be getting 150 cold.

The manual says 175 psi.
My 03 with 28k are around 167. When you do the test, there is a procedure to follow.
I think it was, engine warm, all plugs out, fuel pump electrical disconnect, throttle wide open, turn over till readings stop getting higher.
It took approxmately 7 compression cycles to get top reading.

You may be better off getting a motor from a bike thats hit a wall.
