Well THAT explains the RPMs!
I've had my bike a few weeks now, slowly working through the first time maintenance. An issue that was noticeable when I bought it was that the RPMs would hang high, like it had a vacuum leak or something. Throttle cable was slack also, so maybe some adjustments needed. I couldn't find a vacuum leak, so I just pulled the fairing and started to take a look at the cables. After cracking open the throttle housing and releasing one of the cables, I wiggled it to see how much resistance it had. It slid freely. Very freely.... and came right out! I'm guessing this was the return cable, and it rusted in half at exactly 27" down the line, probably close to where it goes into the cruise control.
Needless to say I'll be replacing ALL the cables just to be safe!

Re: Well THAT explains the RPMs!
Pay special attention to the slack on the cruise control unit, under the right fairing. Clear, detailed instructions in the manual. This is a common cause of CC failure -- seems to need adjustment way more often than I think it should.Heavy Armor wrote: ↑Tue Feb 08, 2022 4:56 pm Needless to say I'll be replacing ALL the cables just to be safe!
Also, just my opinion, but I think the cruise cut-off on the throttle rail is less than useful. I suggest eliminating it entirely and getting it out of the way -- will help with cable install. The bike already has about 1400 other ways to cancel CC, like tapping the brakes or clutch.

Re: Well THAT explains the RPMs!
Hi.Heavy Armor,I replaced all my cables several years ago to prevent that problem.
I had kept them lubed,and they still looked and felt good when I did it,but I did anyway.
I think I still have my old ones,if you have trouble finding them,.

Re: Well THAT explains the RPMs!
Thanks! I managed to track down a hopefully functional set of them including the cruise module on eBay for a really decent price. I was surprised I couldn't find any new replacements anywhere.

I wondered if they were still available,which is the reason I kept my old ones.Heavy Armor wrote: ↑Wed Feb 09, 2022 7:04 pm Thanks!

I wondered if Motion Pro might make them up

Re: Well THAT explains the RPMs!
OK, I'm digging into this, and I have the airbox off to have unrestricted access.... but.... is it just me, or is one of the throttle cables impossible to access without pulling the carbs off??? It looks like it tucked directly between the 2 in the middle and wrapped around the bottom.
I can't envision any way to unhook the end without pulling the carbs off to get at the underside.

Re: Well THAT explains the RPMs!
Yeah. See my comment above about removing the cruise defeat-switch. I suspect that might give a little more room, but haven't actually done it myself. (Either way, that switch is coming off my bike the next time I get in there ... which might be in a couple weeks.)
I use a large roach-clip (er, hemostat), but I think I've also pushed the cable around with a large screwdriver. You do have to torque on the cable pretty hard to get it around to the slot. For this one job, cussing doesn't seem to help. I remember working on the top cable first.
You have to take these cables off to get the carbs out. These cables are just Act 1 for that circus.
(Oh, and by the way ... putting it back on is even funner. Honestly, you just have to keep fussing with it until a miracle occurs.)

Re: Well THAT explains the RPMs!
Heavy Armour,I changed all my cables a couple years ago without removing the carbs,but I custom bent wire,such a clothes hanger wire to help get the return cable unhooked and hooked in place.It is fairly stiff,but can be bent to whatever shape is needed.Heavy Armor wrote: ↑Mon Feb 14, 2022 1:31 am OK, I'm digging into this, and I have the airbox off to have unrestricted access.... but.... is it just me, or is one of the throttle cables impossible to access without pulling the carbs off???

Let us know your progress.
I did mine during[ winter service]so I had time to be patient.

Re: Well THAT explains the RPMs!
I'm not quite done, but pretty well along. I got the "new" cables thoroughly cleaned and ready to go, and I have them in place so I can copy the existing cable routes. I did manage to get the new cable hooked down in the carbs, just took a lot of patience, about 45 minutes with a headlamp and a long thin flathead screwdriver to help guide it. There's just NO room to manuever, so there was a lot of me attacking it from different angles trying to get the cable head in position. That looks like it was probably the hardest part though, most everything else seems exposed. I've just been too busy with other things to pick up the project again. Hopefully this weekend I'll have some time!
