The w series cams are not designed for 1.4 rockers. Not only will it wear your valve guides and stems out it will beat your seats to death with the pressure it needs to keep lift and closing on the quick fall off the ramp of the cam. Not knowing what heads you have I'd say put 1.25 rockers on it and use a good set of springs and be done and get longer life and not abuse it just to run 1.4's IMO. Chad

NOW GAS IT!!!!!

What is the ACTUAL total lift? Were the springs new? If your gonna leave it like its set up now,get the cb 650 springs and be done.

No was not new springs and I dont know how to do the math to know the actual lift and I know that they say not to run a 1.4 but anyone actually do it on their 120 or 110 and it works ok

Multiply 1.4 by the lift on the cam spec card.

when in doubt use the skinny pedal!

You need to measure the lift with a dial indicator. If the rockers are really a true1.4 it will be around 550".

Make sure your new springs are capable of the lift you actually have. Coil bind is a terrible thing and can cost you big bucks. You need to invest in a dial measurement device or rent one.

Chad , I have to say there is a way to run 1.4 rockers with 110 , I have ran that combination for 7 years on 2 sets of heads , comp eliminaters & the ones I'm running now on my new motor are gene berg heads , I use vw 650 valves spring on the berg heads & k- motion 800 on the comp heads & the k- motion springs had almost 250# seat pressure , the key thing is to run pauter roller rockers & racing valve guides cut to allow for the lift ( some will not require cutting ) I didn't do it on my comp eliminaters ( valve springs are "200" longer on the comp heads ) , the new motor I have now is a 2574 cc ( 88 x 96.5 ) and I run a 110 with 1.5 roller rockers ( 645" lift ) and I drove it for
about 12 or 14 rides so far , but you know I'm very easy on my motors & hardly break idle speed , but so far its holding up with the 1.5's!
