Samzero - did you realise that the black plastic part (all gunky) is just a cover? Removing the nuts that hold it in place and taking the cover off will reveal the fuel line & electrical connections so you'll be able to see where your fuel leak is coming from. The pump/tank-seal/etc is secured by further parts.
Yep, deffo a leak there. You need to sort that pronto IMO, fuel leaks in the vicinity of hot exhausts are not a good combination. On the bright side, I’d wager it’s one of the small o-rings on the fuel pipes that’s leaking and not the big green o-ring that seals the fuel pump assembly. Thus an easy fix. My wager is that a previous owner or mechanic has either nicked the o-ring when reinserting the fuel pipe or used a non-petrol resistant o-ring which has since deteriorated in the petrol and is beginning to break down. You need viton o-rings, petrol resistant synthetic rubber, but cheap enough.
Yes now I do. I’ll open it up once I get back to it. I hope it isn’t something big nor costly. Fingers crossed
I’ll definitely look into that. I’m hoping it’s something that would be done easily and inexpensively. Do you know the specs of those rings by any chance?
Thank You so much for the source. Now I gotta figure out size to match and purchase. Of course gotta confirm first so I can’t wait to get home and do that.
Hey Noods, do you have one or two cables attached to your throttle body? I saw earlier today when I was looking a spot that would fit another cable, but never understood the purpose of it on a motorcycle. On cars, it’d be for cruise control. But what does it do on the hyper and should I be worried that it’s not there? Lol
It may well be the O ring, it could have been damaged on installation, with O-rings on fuel couplings I squirt a little White grease before press fitting on the coupling so as not to snag the O-ring.
One size only. Just ask CA Cycleworks for fuel pipe o-rings, they'll know what they are. Re the 2 throttle cables, some bikes have a cable to close the throttle, in addition to the spring(s) on the throttle body assembly.
thank you for that. I’ll check with them. what makes some bikes get that? Is it a part of a package? I felt like the throttle have to be rolled closed the very last 10% I thought to spray something down the cable and hope it’ll fix it. What you think?
Not sure why some do and some don’t tbh, I’m sure someone knows the answer. The throttle should close completely when you release it and the engine should immediately settle to idle. However, it never hurts to lubricate the cable, the linkage, and the spring(s) each year when the bike is serviced, make sure they’re all free moving. Also, the throttle has a small amount of free play/slack in the cable before it begins to open the throttle valves (and likewise at the end of the close naturally) in order to prevent the bumps on the road from unwittingly making your body and hand move and jerk open the throttle. If you plan working on the bike yourself you may benefit from visiting carlsalter.com where you might find an official parts diagram manual and workshop manual.
i think it does what it supposed to until the last few hundreds rpms. Definitely will lube all the stuff that needs lubing and retest
