Throttle cable help!

Hi,

I recently smashed my throttle housing which also damaged the cables. I have since pulled the bike down and installed new cables however I can't seem to adjust them right?

I've followed the owners manual, but the throttle just doesn't seem to spring back as fast as it used too? I'd say it's about 2/3 of what it should spring back?

Here's a photo of how they are set, can anyone tell me what I'm doing wrong?


Any help will be greatly appreciated!

Re: Throttle cable help!

Looks ok there, is there any chance you need to lube the inside of you new cables or there maybe a problem with the way you have routed the cables ie sharp bends or incorrect routing, is the twist grip action nice and free of notchiness etc ?

Hi

Loose the return cable (upper cable) more, and check the route of the cables in the bike, make it a loose as you can.

Re: Throttle cable help!

Thanks for the replys,

I just lubed the cables with some WD40 and it does seem to help a little bit, will have to speak to a friend and borrow his little cable lubing tool.

I checked the routing of the cable's are they are fine, same as stock. Will have another crack at it tomorrow!

Re: Throttle cable help!

Make sure it springs break when you turn the handlebars from stop to stop. I just raised my bars, which required me to rotate the throttle assembly so the cables don't come off the top. That made the bend down to the motor tighter, which caused the cable to bind when I turned right. By loosening the return cable I got it to free it. I found it was very sensitive to adjustment and cable bend.

If it is a bend related issue, it should work better when turned one direction than the other. If that doesn't make a difference, the issue must be in the cable or throttle tube, I would think.

Re: Throttle cable help!

make sure the handlebar end and the inside of the plastic tube are all clean. i remember on one bike i had, there was a small sticker on the handlebar for some reason that suddenly peeled loose and gummed up against the plastic tube. could barely move the throttle at all.

but chances are it's something to do with how you've routed the cables...

Re: Throttle cable help!

Not sure if you resolved your issue, but I will throw my 2 cents in here since I just replaced a bad cable on my FX450..

When I routed the cables I was a bit anxious to get the job done and didn't realize I twisted the cables up top where they meet the throttle tube.. I then twisted the throttle and everything turned super smooth. I would actually say that it returned better than it ever has since I bought the bike, and there was no binding no matter what direction I turned the bars. I was going to just leave it, but the crossed up cables bothered me and I am a bit of a perfectionist so I disconnected the cables and flipped them over so they now ran parallel to each-other from the throttle down the frame to the throttle body. Now the cables bound up.. There seemed to be extra tension on the cables routed this way and no matter what I did, I couldn't get them to move smoothly. So against my better judgement I put them back to the twisted routing and what do you know, super smooth operation again......

This is with Motion Pro replacement cables. I will take a picture of what I am talking about when I get home from work later on, but honestly I cant believe how smooth the throttle works now. It seems like the twist up top somehow relieves some tension on the cables inside and allows everything to move better.

As far as cable lube goes, I don't like to use anything if possible. I put my new cables in dry since they come with a Teflon lined inner sleeve which is naturally super slippery and should not need any lubrication to work properly.. IMO a wet lube only serves to attract dirt and create a nice "wet sanding" environment inside the cables. If I do use lube down the road, I like to use something like a graphite lube that goes on wet but then the solvent flashes off leaving only the dry graphite residue as the lubricating agent.

Re: Throttle cable help!

Sorry for the wait, but here is a picture of my canle routing. You can see how the cables are crossed up, but somehow this relieves the tension on the cables where straight binds up.
