From one issue to another...:mad:

You may have read from my other thread that I was having issues with replacing my bar ends and weights.

I managed to get the broken one out on the left side but the one on the throttle side was giving me grief. So I though I'd take off the plastic throttle tube in an atempt to gain access to the two holes on the end of the handlebar which are supposed to allow me to pry the clip out and then hopefully get the weight out.

In the process, I managed to snap off this bit while removing the throttle cables


Do I need to replace the tube now? It doesn't seem to affect pulling of the cable in either direction but I'm worried it might allow the cable to slip out from the opposite side that is being pulled (if you kno what i mean)..

I think I may have stuffed up. I didn't loosen anything when removing the cables - I sort of just twisted the throttle back and fouth while forcing the cables off the pully thing.

How are the cables supposed to come out? Handlebar side or carbie side first?

How do I go about reinstalling them from this position? I havent removed anything else (i.e tanks air box). Do I need to remove the tank, airbox and carbs or can I simply loosen something from the top to allow me to get the cables back into position?


[Edit(27/07):]
So I've managed to fix most of the issues I had but I just need to replace a couple of screws.

I rounded a couple of the carbie screws when taking them apart:


I ordered replacements from PS in Melb yesterday but got a call this morning saying that Honda Australia has ran out and that it will take 3 weeks to get 'em in from Japan. Anyone know where else I can get replacements or anyone have a few spares lying around?

I know they're just plain screws but I'm no good at finding alternatives...

RE: Help: Throttle issues now...

not sure if it would pop out but yeah, u need to take the cables out from the carby side first...

to get to the carbies side of the cables, u need to remove the tank, airbox and then the carbies itself

RE: Help: Throttle issues now...

Not sure if I explained the issue properly:

There was no issue with the throttle. I only removed it in an effort to get the bar end weight out.

I'd just like to know whether I should replace the plastic throttle tube now since I cracked a little piece off it

and

can I loosen the throttle cables somehow enough to get a little slack in them (enough to put them back on the plastic pully) without having to remove the other carby side end?

RE: Help: Throttle issues now...

not sure if u should replace it coz im not sure if it is an issue or will become an issue in the future...

u can try loosening the cables using a 8mm spanner....just follow the cables down and u will see a locking nut. Undo the locking nut and then the adjuster nut and see if u have enuff slack....if not you will have to pull ur tank and airbox off

RE: Help: Throttle issues now...

You'd probably want to replace it, the spring return on the carbs would hopefully mean that the engine would just idle if the pull cable fell out, but if it happened on the motorway someone could plow into the back of you when the engine braking kicks in.
I think throttle tubes are a pretty generic part, any dual action throttle grip should accept the cables, leaving the only variables to be the bar diameter and the grip length.
At least I think so, the pic looks a lot like the throttle tube I had to modify when fitting knuckle dusters to a CRF.

RE: Help: Throttle issues now...

ok so i got a replacement throttle tube and fitted it by releasing the tension on the cables at the carbie end. Now the throttle doesnt snap back. What is causing this to happen?

The nuts to tension the cables at the carbies are at their max and the cables are pretty new...

I also thought I'd take the carbs off to see what the issue is but... There are two screws per intake right so 8 in total. I can only get access to the bottom 4 because the top 4 are facing the engine. Do i need to loosen the bottom and top screws for the carbies to come out?

It's almost like some duff has installed them the wrong way when the entire engine may of been out...


Please help!!!

It's probably the rubber grip, make sure it's not rubbing on the switchgear.

Edit: Ignore I just read again...

Anyway If you mean the handlebar grip then no it's not possible as I have removed these and the bar end...

you mean the screws in the clamps for the rubber bits that connect the carbs to the engine? if so you only need to loosen the bottom ones to get the carbs off.

And +1 to checking if the grip is rubbing.

Yes those screws. Good to hear. Thanks[hr]
The throttle not snapping back feels like its from the cabie side or something...

With the hand grip, sometimes they can rub against the switch block or bar end causing the throttle to stick, have a look when you twist the throttle and see if the grip touches either the switch block or the bar end when it goes around.

The #1 cause of a non-returning throttle is overtightened cables. I bet that is what you have done.

Loosen your return/close cable way off. Then set the tension on the open cable to get the correct throttle play, (about 1/8"). Then tension the return cable untill there is minimal slack in the return cable, (Watch the cable at the carby's while you open/close the throttle after each adjustment). If the throttle stops returning again, you have tightened the return cable too much, back it off untill it snaps back nicely.

Finally, make sure throttle snaps back by itself with bars turned full lock each way.

A non-returning throttle is dangerous and unroadworthy. Dont ride it like that.

haha oh yeah. Didn't see the edit; don't I look foolish.
LOL don't stress - I think that was a case of me editing while you were replying...

I finally got the throttle to return

The problem:
If you read earlier in this thread or in another I had posted you would see that I was trying to take out the inner bar end weights. In the process I managed to somehow scuff up a burr of metal on the underside of the handlebar and this was causing the friction between the throttle tube and the handle bar which restricted the snapping back of the throttle.

Thanks for the advice guys...

I'm still gonna (attempt to) take out the carbies and give em a clean while the bike is mostly disassembled. I got to the screws but the carbie's still stuck on the manifold. I read some good tips in the old forum archives which I will try tomorrow.

Chukitova - great info. I was looking for what the correct procedure was to do this. It will difinately come in handy after the carbie clean and reassembly.

Why do we cause ourselves so much grief with this hobby? ;)

Funny thing is I did the spark plugs today for the first time and I was so worried about getting access. Seriously they took me like 15 mins to do - I was suprised it was this easy!! :p

Carbs are usually pretty easy to get off once you have loosened the clamps, you can grab the airbox lower on the side closest to the seat, and pull up and towards the front of the bike and they should slip off (unless your manifold rubbers are harder than mother russia).

Finally did it....:D:D

What I had to do was warm up the engine for about 5 mins first. After this they slipped off so easy its not funny. I was expecting resistance so when I pulled I was about 2mm away from loosing my hand cause they came out that easy.

I took the carbies apart and cleaned em out but really they were pretty clean to begin with. I probably shouldn't have removed em.

What started out as a simple bar end change will turn into a bar end change, grip change, spark plug change, carbie removal and clean, throttle cable adjustment, airfilter blow out and a little plastics welding.

Nothing is a 10 minute job.
