I am wondering what the benefit would be of putting in X1 cams into my M2. I can't remember and search isn't bringing me back anything. I just remember the main difference beside FI was the cams, and that the power curve was a tad different because of that. What would it benefit me in installing X1 cams? and, is $55 for pushrods and x1 cams a good deal? (I had to ask Matt, LOL) | ||

no no, it's a good idea to ask. I have no idea what they are worth either. 55 does include shipping... BTW, to anyone answering the question.... The cams came out of a Millenium (2000) X1 with 18k miles, great shape, and the M2 is a 2002 | ||

If I remember correctly, the difference will be an increase in the top end HP with a little loss of torque in the bottom. YMMV | ||

$55 shipped is a steal. Most cam sets for stock 1200 sportys like the D cams in my 1200S go for $50-60+shipping. I was under the impression that the M2 had more midrange than the X1, not low end. The X1 did have more top end though. | ||

I'm going off of memory (suspect at best) and the butt-dyno comparison I did on my '02 X1 and '02 M2 when I had them both. The X1 had the top end nailed. The M2 had more 'grunt' off the line. Never really noticed any butt-dyno difference in the mid-range between the 2. Again, YMMV, so take my input for what it's worth. | ||

So what you're saying is that the X1 cams would be better for overall power then? | ||

I guess it means the M2 cams are more potato potato and X1 cams are more ring ding ding? I think it has more to do with where you shift. Personally I ride more ring ding ding, which is why my 1200S had a drive gear failure at 12,500 miles. (Message edited by Phelan on December 16, 2008) | ||

I shift at high rpms. More beneficial to have x1 cams then? | ||
| Phelan |
Yeah, most likely then. | ||

Putting X1 cams in your engine would be the best band/buck mod you can have. You might have to increase the idle speed due to the increased overlap. | ||

If you're after cheap HP (and $55 is relativley cheap), then the X1 cams in your M2 is a good deal. I'd defer to someone else to confirm, but other than the cams, I don't believe there is any significant difference between an '00 X1 motor vs. an '02 M2 motor, as I believe they were both TS heads, etc. Cams & fueling (FI vs. Carb) were the only major difference that I recall in regards to the motors. Displacement, Bore, Stroke, compression ratio all appear to be the same: Displacement 1203 cc Bore & Stroke 3.5 x 3.8 in. /88.8 x 96.8 mm Compression Ratio 10:1 HP/Torque comparison (Info from http://motoprofi.com/): ’02 M2 - HP/Torque 91 hp @ 6000 rpm; 84.75 ft-lbs @ 4900 rpm ’00 X1 - HP/Torque 95 hp @ 6200 rpm; 85.29 ft-lbs @ 5600 rpm The peak Torque on the X1 is higher than the M2, but notice the torque on the M2 is deliverd a LOT sooner, thus why it felt like it had more 'grunt' down low. Again, YMMV, but I don't think it's a bad deal. | ||

Ok, looks like I'll be getting some X1 cams. Thanks y'all. | ||

I did the same thing with my M2 and noticed more hp on the top end, I did not notice that much if any of a loss on the low end but she has been profesionally tuned! | ||

You are all correct. The big difference from the X1 and M2 are cams and front end. You will notice a nice change if you normally shift at a higher rpm now. |
