Timing problems on the 450 Bomber

[mo goldie]

Well now you can have some good news Roy..... I have spark just looked at all the wiring that they say and then tried something and turned over rhe rotor and heard something looked at both spark plugs and got spark .... well nearly fell off my stool lol. Anyway this arvo I am going to take out all the wiring connectors and replace them with the much more neat and works better block connectors like they been using on bikes for years.

Oh then will have to look at the timing rotor.... always something as they say ...but will get there as got time it's winter and dam cold ..so all bikes tucked away.... 😆

[mo goldie]

are well now the good news I have it running .... Yahoooooooooooooooooooooooooooooo lol

yp all running the carbs need setting as I did take them all apart and ultrasonic them and the Timing will need to be set too, it is near Roy but like you said on yours it go`s all the way to the end of travel up against the Exhaust cam washer.
so Cam plate is on full Addvance but it sounds good so with some fettling should be all ok,

Did Not hear back from Ashley about the Rotor`s if they are different or Not but it would Not surprise me if they are,
so I have marked the rotor up using a Dial Gauge for top dead centre so if I measure the gap from LF mark and TDC and the mark I have done where TDC is I should be able to to a strobe light on it to get that right do you think ?

Aye, good stuff there mo.

Yes to timing, as long as you can get a confident degree position against crankcase reference, then strobe it on that to assess.

[mo goldie]

Yes Thanks for all your help as its been a bit of a drag at times but we there ha ...well nearly 

got a bit of a leak on the right carb soon fix that but getting them both dialed in and and then I hope will be all good,
is there any way to check if the Rectifier is working as need to check if charging is ok ?

cheers Mo

Check battery voltage under all conditions, usualy numbers in Honda manual

[mo goldie]

Well Bryan

I just fitted one of the Digital ones so wanted to check that it is doing its job right as that is one of the conditions of the warrantee for the E/I .

so first put a meter across the batt see what's going in .... as My battery went a bit flat after using the E/starter for all them times ...so on charge Now.
 

also still got to sort out a rear light lens as the one I got all cracked too.

[Bryanj]

You must remember the 450 charging system is one of Hondas most agricultural ones where extra charging coils are switched in when lights turned on, if the electronic ignition needs a steady precise voltage it should not be on that bike

[mo goldie]

Well that's the one they recommend if you don't use it you wont have a warrantee.

You will need to connect your multimeter in series between the battery and the live lead on the 20amp fused connection on your Fluke. Run the engine, but don't use the electric start as it will blow the multimeter fuse, then take a reading and ensure it's over 12 volts. You can't just test these on voltage across battery live and neutral as an AGM battery has more static voltage than the alternator can produce so it doesn't tell you anything. Try it lights on and lights off. If that doesn't make sense to you have a look at the end of my Bomber build thread for a better explanation.

What was the wiring mistake that caused the lack of spark.

Hi


Well Roy first my fluke don`t have 20amp its got a 10 amp any good ?

Yes also right about putting a meter across just the battery as it did not move well went down.

the wiring fault if you look back was that the white/Black needed the + 12volt as I thought it was an earth, till as you pointed out that Honda done some strange things on wire colors lol.

if i need to get another alternator are they hard to get or is there someone who rewinds them as might need one  ?

just asking asking as the one on there don't look that good to start with as the windings look to be flapping around well some of them do anyway,

[Bryanj]

Windings are fairly robust, charging problem are usually bad wire or wron connections

Bomber ones often fooked Bryan .. particularly when damaged when the starter clutch fails (which must have happened on Mo's bike) .. plus they are cloth wound not epoxy coated, The later 5-speed fits OK and is epoxy dipped like later 1970's Hondas.

[Bryanj]

Thanks Ash, only ever did the 500twin, in that case measure the ac output of the wingings when running

[mo goldie]

I just wish I could get one ha LOL.

Hi Ashley

did you get tro look at the rotor`s ?
i got my timing near as you can get it right so rotro must be ok ...........running a bit like a pig tho....... carbs need setting up
I think.
