THIS CAM HAS VERY LITTLE EXTRA LIFT,(LESS THAN .5MM) BUT A LOT MORE DURATION!!
THE "DURATION" IS HOW LONG THE VALVE IS LEFT OPEN,, AND THE LONGER THE VALVE IS OPEN THE MORE FUEL/AIR MIXTURE GETS IN THE CYLINDER,, SO MORE MIXTURE MORE POWER !!!
THIS IS MORE OF A LOW AND MIDRANGE TYPE CAM,, AS FAR AS THE POWER BAND GOES.. OF COURSE THERE WILL BE SOME TOP END BENEFIT'S AS WELL !!!
THIS WILL FIT RIGHT IN WITH NO MODS NEEDED, AND WITH VERY LITTLE EXTRA LIFT THERE IS NO NEED FOR STIFFER VALVE SPRINGS...
NOTE!! the pin hole (see #14 in diagram to the left) may/will need to be cleaned out as it is a tight fit and the coating the factory adds to the cam makes it too tight of a fit for the pin on most.
FOR POINTS MODELS SHOULD WORK AS IT IS
FOR CDI MODELS YOU WILL NEED A 10MM LONGER CAM ADVANSOR 6MM BOLT (SEE B81F BELOW)
here is what our good customers said about the cam
I just wanted to let you know that words cant express how greatfull i am for dratv!
I ordered the performance cam because my original cam journals were worn past spec. It would rattle at high rpm. I was hoping this cam would increase dia and be tighter.
I can say it exceeded my expectations because not only did it bring it back to oem journal tolerance, but it gave it a performance boost as well.
I just replaced the valves and oversized piston from the good dr. and once i put this cam in, it came to life!
It has a coating on it to hold oil and tighten tolerances. Perfect.
Thank you again dratv for allowing us to maintain our old babies and keep them performing better than ever.
Life long customer.
Hello Doc; I told you I would give up a report about this cam after I installed it. Well I got it in and I can tell its there. I am not sure how it would perform on a stock motor because I have it in my 104cc CT90 and its had alot of other work done to it. The 104cc overbore+Your 110cc carb + I ported the head and intake + Race 3/4 in exhuast.It sounds good out the pipe!!! I had to advance the timing just a little to find that SWEET spot. Over all I think its a WINNER.Thanks Eddie O. Sunny Calif.
Hi, I set my timing to 7 degrees advance and the all stock machine is running smooth. I can now keep up to my wife's fresher CT90 on hills even though I weigh 70 pounds more than she. I consider this to be a success!
(this is what one customer said)
Thanks for the cam and fast shipping,but you should list this as for 110s too becuase I just installed it in my 82' ATC 110 and it worked great. I could tell a big difference down low and in the mids,anyway thanks again.
NOT FOR CT110'S !!!

THESE WILL REPLACE STOCK SPRINGS ON STOCK CAM ENGINES TOO
|CAM INSTALLED INTO A 1985 ATC110I have just installed this cam on my 1985 Honda ATC 110 and I can tell you that this made a huge difference on the low end as well as the mid-range. For the price this is the best easiest upgrade you can do. Took me 20 minutes to install. Here is a pic of my bike with all parts supplied from DRATV. Thanks for all your help!! Best Regards, Martin|
