Looky what I got me hands on!

[motorbyclist]

are you talking about the idle adjustment? have you removed the carb and cleaned it yet? if you have you should know if the throttle cable/assembly is working correctly

spark plug is wet or not, it's definitely wet with petrol. There troubleshooting offers 3 ideas...1)Flooded carb, 2)Choke valve closed excessively and 3)Throttle valve opened excessively.

4) blocked air filter.

temporary solution: remove it.

air starts at atmospheric pressure (1 bar), assuming ideal gas and no temperature change pressure will increase 8.2 times to 8.2 bar.**

google converts 8.2 bar to 118.93 psi

**apologies if i stuffed up the ratio but it's safe to say the pressure should be higher than 100psi

K well yeah the compression gauge showed more like 7 bar... Fuck well a lack of compression gives a ton of options...

-Engine not cranked (clutch slipping)
-No valve clearance
-Valve stuck open
-Worn cylinder and piston rings
-Blown cylinder head gasket
-Flaw in cylinder head
-Improper valve timing

Where, the, fuck, do, I, start?!

Thats plenty of compression...

Yep I've cleaned carb. And yeah well I took the throttle apart etc and put it back and thought it looked all dandy, but the throttle itself has no "spring-back" to it, i.e. I can just turn the throttle back and forth and it'll just sit wherever within springing back into position, and I don't think that the throttle wire cable itself is moving inside the rubber tube, in that it's moving the entire cable as one.

Air filter doesn't appear blocked, but I can remove that to test easy enough.

You know you wanna just come out on Sunday, I'll even let ya ride it once ya get it going

You're probably flooding it good then...

Thank fuck! K back to my 3 options, with Andrew's added 4th. Sweet tomorrow I'll pull apart throttle assembly and see what I can do. I know that the choke is working fine so I think I can rule that one out. I'll take the air filter off and see if it makes a difference too.

You're a man of many words per post today Stevo!

Any insight as to what to do with the throttle cable then? Just detach both ends and see if I can get the cable moving freely inside the housing?

Are you giving up your day job and becoming a postie lol ?

I doubt the CT90 will get to the speed limit around here

But it can try!

Might be a good idea to have a working throttle ya

K one question... Does anyone know where neutral is on these Hondamatics? As far as you can kick down? Can't really tell with no chain and all, but would prefer to try and start it in neutral haha.

would be at the top wouldn't it? don't you have the manual there?

that should be sufficient compression, and how is the clutch in any way related?

I have a manual I downloaded... It doesn't tell ya how to ride the damn thing though!

Gonna get the chain on tomorrow hopefully so will be able to tell haha.

Don't ask me, I just copied outta the manual's troubleshooting flow chart!

EDIT : Google says that you just kick the front of the gear lever down and it'll end up at neutral.

Forward to go down a gear and back to go up. Works like a see-saw.

So yes, you're right, step on the front gear lever pedal and you know when you're neutral when you can move the bike freely.

There should be a neutral light that comes on.

Progress!!!! I took apart throttle cable but it doesn't really seem jammed, maybe it was just screwed in on an odd angle or something.

Removed air filter, sprayed a ton of starter inside and had success with the choke shut, engine would fire, rev up and then die.

Opening the choke now leads to the following video!



As you can see... Engine is pretty damn spluttery, and as soon as I close the choke whatsoever the engine dies.

It won't start at all or rev at all with the choke shut.

Also, it won't rev with the throttle when the engine's going with the choke wide open.

Any ideas where to go to from here? Still sounds like I may need to play with the throttle somewhat... Although it is moving freely and even snapping back into position.

A mate's popping around soon with an angle grinder and we're going to attempt to put the chain on.

So yeah... After listening to that video what would ya suggest?
