Cam swap?
09/25/16 at 08:26:13

Wondering if anyone has done just a cam swap (with a different carb and muffler)? Not the higher compression or big bore.
How'd it work out? Which cam did you use?
Have the valve cover off, lots of stuff apart. Don't want to be breaking in a new piston with all the other changes I'm doing. And I'd like to see the beast run this year Huh

Thought maybe just a different bumpstick might make a slight improvement.
thanks,
-Armen

Reply #1 - 09/25/16 at 08:48:36 Yeah, cams are available, I wanna say three levels of differences, not necessary to change carb, but I think that's been done with good effect. Is it cost effective? Ohh, who cares? If you're going with a cam, exhaust makes sense, but don't forget about the intake, and the head, especially the exhaust side, is just a mess design wise..

Reply #2 - 09/25/16 at 09:34:49 Justin, I put on a 40mm Mikuni flat slide pumper that I had laying around for 20 years from a project that never happened. Mated it with the biggest K+N pod filter that would fit. The muff is the long RYCA unit, which is supposed ly their quietest. Hate loud bikes. Just emptied my change bucket and have a few bucks to burn

Once I dialed in the jetting I love it!

Would actually like to get the bike running before I die. Cam cover is off, so no additional time needed for the bump stick. Don't want to dismember any more.

I went with 97mm & Boretech coating, ported head myself.
I used Webcam standard grind has a little more lift & duration than stock, I didn't want a camy feeling engine just wanted it to breath and be dependable. Also had rockers hard welded.
But for the same money they have 3 other cams.
Cruises at 70 fine,whack the throttle and it pulls hard right past 100 mph that's all I need,very quick as well 0-60/70
Really fun to ride has good power across the board !

Armen,
I would suggest you strike up a PM conversation with Lancer. He worked to develop two of the cam profiles that are out there. If you want a wide power band I would suggest you confirm with him but I would recommend his mid range cam. That is what I went with. It is not extreme but adds some meat to the power. Then if you have the head off (or if you want to work carefully with rag plugs) you can do some careful simple die grinding with a dremel grinder and take out the restricter that is in the exhaust port outlet.

Lastly if you have extra money after all that then I would recommend considering a carb upgrade if you want to improve throttle response. Obviously not absolutely needed but one of those nice to have things. Again Lancer is a key resource there for input and buying assistance.
