Your engine is a late model honda? My experience is they have a security system called HISS. You must have the key positioned right next to the transponder for the engine to run.

From memory, I think it cuts the ignition and fuel circuit (no fuel, no spark) so the bike will turn over, but it won't start.

I originally bought the bike with the HISS system diconnected, and the bike started and ran fine without.

Should still be ok shouldnt it?

You can't just disconnect the hiss, it's an anti theft system. The ecu is coded to the key. You would need the ecu, key, transponder and ignition barrel from another bike, or an ecu that doesn't have the hiss system (some American models). What's make you think it was disconnected? I would be plugging the transponder in, putting it near the ignition barrel and see if the bike will start.

Well, here is the story.

I got a good deal from Adreline performace bikes in VIC, the bike had no ignition as it was a crashed bike, He said in the add it will need ignition to start up the bike.

After speaking to him for a while we came to an agreement that i will pay an extra $200 and he sorts it, sends me a video of the bike runing and i will purchase the bike, Which he did it, sent me a video etc..

When i got it it had no ignition or keys, he said put the two red wires to gether then crank it and it should start. I did that and it started and ran no problems, I left the engine on the bike for a few weeks, starting and runing it regulary no probs.

So i gathered he had disconnected the HISS system. I may be wrong.

Would photos help or should i just get an ecu from US and go from there?

Thanks

Just a thought, could you not contact the guy and ask him exactly what he did for the 200

Maybe it didn't have HISS to begin with. Maybe he brought an a different ECU from a country where they Don't have HISS (I did this when I blew up my Blackbird ECU). In any case, it sounds like it should go.

I wouldn't buy anything until you figure out what has gone on. It was running in the bike, but now you have transplanted it into the buggy, it won't run? I'd bet my left nut you have missed something simple that is holding out the fuel/ignition circuit.

What about tip over sensor? Clutch switch? Sidestand Switch? Neutral Switch? Have you jumped the fuel pump yet?

Think I have found the problem.

I got a voltage meter, checked on the fuel pump, 12.85 volts at the plug to go to fuel pump, but in the unit ( I am using the original bike internal fuel pump system,) where it plugs in to the fuel pump, i can only get 0.03 volts,

So there is a fault with wiring, strange as nothing has been changed since it was taken off the bike.

I jumped the fuel pump and it works fine!!

But I have a feeling, there are some wires that go from the fuel pump to the base of the unit ( brown, Green etc...) wondering if the fuel pump is not getting earthed? I am not a pro with electrical but what makes me think that, is that the original bike fuel tank was steel, now I have an alloy one??


Thinking of taking it in to an auto electrician to check it out tomorrow or sometime next week.

If you can get at the pump might be an idea to run a earth strap from the body to your frame, but as you say one of those wires is probably an earth.

Playing around with that at the moment.

Just wondering what you guys do re clutch cable for the hand clutch cables?? get the bike one extended?? or buy a longer universal cltch cable and adapt it to suit??

Looking forward to replies

Thanks

I was lucky mine was a good fit from the bike. I had my gas cable made to order so i would imagine you could do the same with clutch. I would try and get one made to measure rather than extend

agreed, i have a memory of someone suggesting push bike grear cables? maybe something to look into. (if its a cable)
Mine was hydraulic, i had pirtek make one to suit. cost an arm and a leg though, i've since found out theyre considered the most expensive hose place in the industry.

I did suggest that to my brother who has more mechanical knowledge than i have, he didnt think they would be strong enough.

But might just work as a temporary measure. Worth a shot just to get going.

Found i can get the perfect cable online, but will take a 3 weeks to get here.

Thanks Again!!

Yep, Redoing the whole frame in Chrome-molly :twisted: :lol:

Na Kidding


Sorry no pics at the moment,

Life got a bit in the way,

New job etc......

Had to move workshop too.

Trying to set up the workshop again.

But having trouble with my engine trying to get it to start.

No power going to the fuel pump.

I haven't altered the wiring yet, it was running perfectly on the bike when i got it. :roll:

I am just tempted to get a ECU for the US as they do not have the immobilizers on them. which is the HISS system.

Hoping to have some cash this week to order one.

Then i can get the engine started,

There isn't really that much more to do,

wiring
exhaust
brake lines to be set up
panels

I will post some more pics when i can, may not be till this weekend tho.

If it was running perfectly before you pulled it from the bike and harness is unaltered
Side stand switch .....
If that's not connected or in the right position will allow engine to crank but not fire ?

Thanks Ray.

I have the side stand set up. I tried in both positions. Still no luck.

hi Ben,
Mate is it going yet??
If not have you tried the tip over sensor? Or the clutch switch?

Both these gave me grief last week in my electric test run.

Thanks for your comments.

It has been confirmed its the HISS :cry:

Immobilisers are $800 plus.

Looking at other options, wether to sell the motor for parts or someone who wants a spare motor for a CBR954 Track Bike. Currently have a guy interested.

Will see what happens over the next 2 weeks.
