Yes, I talked to Web Camshafts about this several months ago. They have never built a set for the GL1800 engine will will do it. You could buy a new set and have them installed when you get them. Then sell you originals for someone else to use as cores for rebuilds. Some other downsides: You would need to make sure there is adequate clearances when you install them since they don't know exactly how much lift and durance can be increased. Then to take advantage of the new cams, you really need a new tune. Guhl has a reflash but had not tested a tune on the GL1800 with cams. It could be done with some time and testing on a local dyno and have Guhl make the changes.I was lurking and spotted this question, I just had to register to respond.
webcamshafts.com they're outta riverside CA, and will hardweld & grind any cam to the spec u desire including the GL1800 cam. only downside is you have to pull your cam, send it in & wait, the winter down season is almost here... Price is 700 give or take a few $ plus shipping.
I have used several cams from them in my ATV's including a raptor 700 & trx450r and had very good luck.
It would be good to compare the specs. It would be nice if the Rune cams could be dropped in for some extra performance without any other changes. Often, on some bikes, people replace the exhaust cams with a set of intake cams or maybe its the other way around but you get the idea. So maybe someone could check also the intake vs exhaust cam specs on the GL1800.For sure I would check clearances, anyone know the specs for the rune cams? I am not sure exactly the differences except the honda part # is different. I know the rune made less hp, but more torque, it did also have 6 throttle bodies, a different ECU & exhaust I'm sure all that factors in too.
The 2014 Valk has a 205 degree duration in both the intake and exhaust cams.
For those that may not be familiar with cam timing and duration:
opens at 5 degrees ATDC (at 1mm lift)
closes at 30 degrees ABDC (at 1mm lift)
Duration: 205 degrees
opens at 30 degrees BBDC (at 1mm lift)
closes at 5 degrees BTDC (at 1mm lift)
Duration: 205 degrees
Good info. Thanks.
Were you able to get lift for each?
