I have my quad at dealer to check key, it was right so as long as it is open I want him to retard the cam timing but he doesn't know how. I was looking for a simple explanation to tell him. Thank you.

 

Travelor,

Here it is 4 all to see.

Cam timing retard instructions
0. refer to service manual 4 aditional help.
1. remove cam covers and cam shafts(both front than back)
2. remove stator cover and stator
3. remove clutch cover and primary clutch and peak hole cover 4 intermediate shaft.
4. remove oil pump and chain
5. remove intermediate shaft sprocket from chain
6. rotate crankshaft 180* minis 1 tooth
7. reinstall intermediate sprocket and chain
8. turn crack shaft counterclockwise till timing marks line up 4 rear cylinder
9. reinstall rear cam shaft and chain- the front timing mark should be up 3mm= 10* retard and cover
10. rotate crankshaft 270* and install front camshaft and chain- timing mark up 3mm install cover
11. install oil pump and chain and stator and cover


Remember to drain oil and coollant and fill after done.

12. fire the puppy up.

Thanks kawituner, That was exlained very well. It looks like quite a few hours to do. Didn't realize the pulling cams. Can you tell a noticeable gain in acceleration? It is apart for the key so may be worth the extra hours to go for it.

 

Travelor,

you will notice a difference but if you want to get the max put a 8* key in while it is apart.
it will run on pump gas. 93 Octane

the only downfall is that if you want to install different cams you will have to reverse the cam timing or the cam timing will be off.

if you arent planning on changing cams after this go with the retard- you will be happy with it.[img]i/expressions/face-icon-small-happy.gif[/img]

Just Do It.

 

kawiTuner ~ Thanks for sharing your secret! Have you ever compared doing the vforce cams to this? ~coop

this will put the prairie cams at the same performance level as the V. [img]i/expressions/face-icon-small-happy.gif[/img]

 

TUNER... thanks for posting that... I won't personally do it, as I've already got FST cams, but I have been asked several times, & I didn't really know what was involved ...

there have been several forum members that have retarded the cams 1 tooth ( 20* ??? ), with excellent results... have you tried this yourself, it sounds much easier to do, & it sound like there are much gains to be had in the top 1/4 of the power band ???

 

I think 20* is to much but it may be better than stock but I havent tried it.

it would be a whole lot easier though.[img]i/expressions/face-icon-small-happy.gif[/img]

 

For what its worth, I think it will be much easier to simply install stock v-force cams and get the same or similar results as repositioning the stock P650 cams. In fact, I recently bought some (used) stock v-force cams for a very reasonable price from Mickey D. I think that the price I paid for these cams is more than worth the trouble I saved by avoiding the procedure explained above to reposition the stock P650 cams. But that is must my opinion.

I can't wait to install my cams...I'm waiting for a chance to go ride my quad with the 22" tires that I recently installed so that I can measure top-speed, check for hitting the rev limit (doubtful with Dyna cdi), etc. and then I can install v-force cams and compare it to the perf. of my stock P650 cams.

Happy trails...[img]i/expressions/face-icon-small-smile.gif[/img]

 

Kawituner, Does this setup work with the 4* key? I would have to order the Bigger key and want to get it together. Maybe I will get the dyna cdi to get the extra timing. Thanks for the good info.
