Glixal A9 Camshaft

[magoconnor]

Hello. 

Has anybody experience with this camshaft?

If you do, could you maybe tell me if it is a "real" a9? 

And did it make a change for the better, upon installing? 

Good day to you all.

I bought one from glixal about 2 years ago. If you mean the one with the holes on the gear and the 'xs' bearings, it has the same lift but a longer duration. I installed it on my 47mm. I got a little top end but not anything dramatic, about 3kmh. Maybe with a more open exhaust and a free intake, you will get more. I use the stock exhaust and stock airbox. Also i think that you will need to spin your motor above 7.500 to see a bigger difference. My scooter has a detuned cvt so i can get more reliability and that's why i'm still using the stock one as it provides more torque at lower rpm. You can try it as it is a low cost mod and if you like it, you keep it on. These xs bearings are good as i used the camshaft for over 10.000 km without problems. Worst bearing brand are tpi by far. I bought a new jinlang motor that uses this brand and after 1000km camshaft's gearside bearing failed and after 3000km crankshaft's cvt side bearing fail. And now after almost 30.000 i replaced my transmission bearing too. So keep way from any tpi bearing.

Okay, thanks for the report.
I will difinitely look more into it, and make sure it's the xs bearings.

I put one in a friend’s bike after we did a 50mm BBK. He picked up 2 mph with all stock gearing. After the BBK, he could get a max of 45 mph. When we swapped in the cam, he can do 47. I also put the same cam in my bike. I did it at the same time as the BBK, so I can’t tell you if it is any better. My first test ride with a big bore head but normal valves today had me at 45 mph. But this is mot broken in yet, and we haven’t done any jet work yet. So I guess I’ll say it didn’t hurt, and I think I paid about $12 for it, so it’s fine.

My friends bike is doing almost exactly the same 0-25 times but at a little higher speed. There is no difference (to him) in “drivability” so he is happ. And the fact that at least today he it faster then me, makes him very happy.

Yep,ya got to love the ground pounding radical lope of a cammed out scoot engine,😂..but seriously I had my doubts about the cheep a9 cams,but said w.t.f I'll try it ! I am a hot rodder at heart and every little bit helps.! Even taking a big dump, I mean poop before a scooter race.!! 💩lol

Got one myself - basically lets the engine flow a little more at wot. Also reduces the dynamic compression slightly making it easier on the electric starter. All in all, not a bad purchase as long as you're there. I do plan on trying a couple other performance cams when i get the chance (ncy and ssp-g)

[ratdog]

You know, I have never seen any specs on any of these “preformance” cams. Wouldn’t it be nice if you got all the specs on them like we get for real preformance cams? We all assume that a Glixal A9 cam is the same as some other brand A9 cam.

I just put one in my bike about two weeks ago. I'm running a 47mm BBK on a 2011 Toa Toa and I can def tell the difference in mid to high rpm torque. I gained 3mph on top end and shaved 4 seconds off my 0-30 mph time. As stated before the lift isn't any larger just a longer duration. I'm still running my a stock 39mm head with a very slight port job and port matching with my 47mm BBK which ends up cramming a lot of fuel into the small 39mm combustion chamber. So with my set up it gives me great result. Well worth the $12 - $15 dollars. Oh and I can cruise around 37 mph at about 2/3 throttle instead of WOT now as well. I top out at 43mph. I run out of gears before motor. So I suggest to go for it.

In the limited time I have been on this forum, I have seen nothing but positive results with this cam up grade. A couple of small things. First, please get some assembly lube for installing this. Put gobs of this sticky oil all over the lobes, followers, and don’t forget the inside of the the bearings. It is real easy to spot the two tiny holes to set your cam timing, but unlike the stock cam it has a bunch of other holes in the gear. If you have any doubt, remember the lobes go down ( into the engine). Of course loosen the adjusters on the rocker arms before installing.

The bolts that hold the rocker arm assembly, are also your head bolts. When you loosen them, do so in an “X” pattern. ( like maybe half turn top left, half turn bottom right, half turn top right, half turn bottom left). When you install the rocker assembly, do the same x pattern whenthihtening. Please use a torque wrench! I like to be on the safe side and tighten all four to 10 Nm first, then to 15 Nm and finally to 20 nm If you don’t have a torque wrench, check ou the bicycle places. I work on expensive bicycles so I would never be without a torque wrench

No one ever seems to provide info with these cams, but I use .004” valve lash and it has worked well for me.

Love to hear your before and after results

Good luck!

Does anybody have some specs on this cam?
I think is safe to say it provides longer duration, but is the lift the same as stock?

[ratdog]

you might want to check the last post I did in the "new project" thread Walt refused to tell me who's cams these were, but from the pics I See on line I believe #2 is the cam you are asking about.

I also measured the lift, but it came up as .185 on all three cams. that seems very low to me. I'm wondering if I mounted the dial indicator too low and was "bottoming out" the measurement. I'm sorry now that I didn't check that again while I had them mounted up.

I dont know if anybody out there have tried it, but I plan to use this setup.

50mm airsal piston + 47mm Bvh (21\19) + stock crank.

Now I would really like to use the glixal a9 but Im not sure if I will have enough clearence.
The piston is 0,5mm taller, the intake valve relieve is 22mm, my intake valve is 21,5 so that should fit.
I guess it all comes down to the lift on the glixal a9 cam..

Has anybody compared it to stock? 

[ratdog]

Ok, I have been plotting this cam by teeth on the gear. Surprise! This has LESS duration then the stock cam and the “meat” of the lift comes comes later in the rotation then stock. I would love to find someone out there that could take my figures from about every 5 degrees of rotation and polit a picture of this and the stock cam so we could overlay them. It’s really hard for me to get my head around how this can have less duration, and the same lift, but somehow be a preformance cam.

as noted before the lift is kind of the same its just a bit more aggressive and has some more overlap.

But if you are not sure about the clearance. well it hits or it doesn't hit.   important thing then would be to have some stiff valve springs
so you don't have any valve float.   And my BVH has some Really strong valve spring's (I guess valve spring's from an 125cc gy6 type)
so I think your head also should have some decent springs..

and for the 47mm head on an 50mm would be nice to nock over the edge I think.
i also did that on my head. not sure how it will perform since it hasn't run yet.

[ratdog]

one of the surprising things I found is that at TDC on the intake stroke. the A9 cam has MORE clearance then the stock cam in other words, the valves are not as far off their seats with the A9 as with the stock cam
