Okay slightly differant problem with "Frankie" this morning.

Ignition On
Kill Switch Off
Fast idle to Max
Hit Starter

Bike fired first time, reduced fast idle (maybe too quickly) engine died

Repeat as above but now engine turns over without firing (clocks DO NOT reset) . Tried twice no change.

Gave up .......................any idea's anyone ?

Kiwi, when I first got my bike exactly the same thing used to happen to me. I believe (?) it's cos it died while in the fast idle mode. Long waits for plugs to dry. Very occasionally I get it again if I'm not too gentle turning down the fast idle. It just doesn't seem to like starting if allowed to stall while in fast idle.
 
How about trying again and if no go, turn the fast idle off and fgive it some wide open throttle. just be ready to let go very quickly!
One of my cars used to do this, a turbo Audi A4, if I started it from cold and justo moved it up the street or something, it wouldn't start next time, even up to 24 hours later! I shat myslef once swearing the cambelt had snapped!
Then after 20 secs cranking it fired...

DO NOT GIVE YOUR BIKE FULL THROTTLE.

It WILL flood. Leave it for an hour, yes boring, then try again as normal. Full chokes NO throttle.

Big twins flood easy. Sometimes I just run mine over on her starter to clear her lungs. But I have a 'Mod' to do this.....:devious
 
Cmon flick....spill the beans ...............whats this mod (Is it an R1 engine under the seat ?)

Ha... a few lucky ones in 'da zone' have witnessed my high amp starting key. But I fear if I shared the love the 'da zone' would go down into melt down.... :biggrin

ps. Did you vote for me?
 
Using jump leads and the National Grid is NOT clever or smart !!!, but is quite ingenius :thumbup

Of course I did :doug

Sorry but totally disagree on the full throttle starting causing more flooding.

By opening the throttle wide open you greatly increase the volume of air to fuel and it has effect of drying the plugs.

The rate of injector pulse is determined by the speed of the motor as much as anything else and that doesn't change full throttle or no throttle when your turning it over.

The leave it and wait option is probably safer in terms of your sprag but sometimes 1/2 hour wait just don't cut it.
 
Certainly would NEVER use Full Throttle ...................the thought of exploding sprags scares me a little too much :pirate

I abandoned the bike after a temper tantrum and took the car .......will see if it starts tonight (if its still there that is :exclamation) :confused

it's widely used Kiwi across all sorts of bikes and Rsv's alike.

i have used it very sucessfully and i know Badger, Sabre etc has too.

It's not something you want to do if you don't have to becuase it takes a good few turns to clean the plugs but if you need to get going it's a get you out of jail card. It has to be FULL throttle to work properly though.

Big crossers, motards etc are notorious for fouling plugs and the full throttle method is the standard way of starting them but then they don't have a sprag.
 
Well im gonna fit Frankie with a kick start and decompression lever...............oh holdon aint the Apes low compression ?

or an XT660 donkey engine
 
Agree with Spoonz, Full throttle relates more to getting more air in there, widely accepted for cars etc, ask a mechanic, although it was probably more effective when it related to carb'd engines.

Obviously, there is the risk of redlining your bike, but it won't suddenly fire up if flooded you'll catch it spluttering.

By tonight, just treat it as normal first, with fast idle etc....
 
As with Spoonz and JayB, full throttle to clear a flooded Rotax V2, just be ready to shut off the throttle as soon as it fires.
 
Agreed - the full throttle thing works.

Did it on my old Mille a few times when I flooded it, and never had any sprag problems. Obviously don't keep the starter going when the bike has fired up, that would be a little foolish :eek:
 
Same thing happend to me this very morning Scott.
Thought I'd take the bike to an apointment 40-odd miles away so togged up, dragged it straight off the Optimate and out of the garage, normal approved starting proceedure (it ALWAYS starts OK like this) - would not fire. Cursed it roundly but could not be arsed to take off all my gear and get in the car, so, set idle to off, full throttle, five seconds, she fired. Dropped the throttle and she stalled. Same again - wide open throttle - fired, caught her on the idle and fine ever since.
Sure, laboured the sprag a bit but hell, we know what we're doing now eh Scott? And it ain't that big a job!:thumbup
 
This full throttle thing just scares the crap out of me:eek:....................but yes I reckon I could rebuild the sprag in my sleep !!! :thumbup

Let me try it on somebody elses bike a few times to get the practise ....maybe Tim's (areesmille) :doug

Especially as he's used an 8 inch (sorry Tim 200mm) coachbolt to hold the oil filter on !!!...................................

You bunch of gitz

Yep the guy before me has fecked the oil cover retaining thread, hence why he has used liquid gasket sealant.

OOOOOOOOOOOOOHHHHHHHHHHHHHHHHHHH FFFFFFFFFEEEEEEEEEEEEECCCCCCCCCCCCCKKKKKKKKKKKKKKK
 
When my Mille refused to start and then flooded, I would take the pillion seat off and unhook the fuel relay, turn it over till it caught on the fuel already in there. Then quickly hook the relay back together and and start it. Often worked when nothing else would. My sprag was too battered to try the full throttle start.
