fit another and start the bike, switch the fuel off and rev the engine freely to clear the flooded crankcases...when it dies switch on the fuel, then off again and re-start the engine and repeat another couple of times

well then you will find that your carb is over filling check the float height setting check the float needle is free to move maybe before any of this, give the carb a tap with something like the wooden stock of a hammer just in case it jolts something free

did it run well until it cut out?

ok try with the fuel tap switched off until it runs out of fuel

Try it with choke and let us know the result Jamie

Peter, not familiar with the bike but are they entirely rubber and fixxed at both ends by circular clips, or are they bonded to a metal plate where they meet the cyl head and thus bolted there ?

Greetings Adam and to the YOC forum

ok then my last shot is suirt around 3cc of petrol directly into the spark plug hole snd try with that, the reed is an issue though, there will be a bend tolerance, off now

sorry dont understand that, pour out of what?

andrew i'm on my lunchbreak, cant wait long for replies!

so it will either need priming by whatever means was given by yamaha or you will need to take off the vac line from the manifold and suck on it to open the fuel supply and fill the carb

how do you know that fuel is in the carb, it isnt supposed to get there without the engine running (ON A VAC SYSTEM) and you had the carb apart so it's empty of fuel isnt it?

i dont get that, is there a prime facility on the tap?

ahh there may be a problem there if you've had the carb off! am i right in thinking the fuel supply is vac operated?

Greetings clive

Andrew, first things first i must say that i'm not familiar with the scoot..,.but is there plenty of fuel in the tank i assume the fuel supply is vacuum operated?...if so check the vac line from the inlet manifold to the fuel supply tap, see it hasnt come adrift, split, kinked etc etc

hmmm, can the shocker bushes be swapped for the old ones ? or? http://www.superflex.co.uk/products.php?cat=393&pg=3 did you get the swing arm bushes fitted in the end?

an intro in 'new members' is always welcome dave is your autolube out of commision? did you premix at 20/1 as per title...why?

greetings 'Grandad'...never too late is it The bike looks superb, no wonder you're set up with it

chains dont actually stretch, the pivots wear and thats how they become longer, the amount of pivots wear can be greatly reduced with regular lubrication. Look after your new chain better than the old one and it will last longer

possibly blocked pilot jets, a common culprit...can you see daylight through them...with a magnifling glass? oh and theres a tiny orifice at the bottom of the choke passageway...in the bottom of the bowl ...the carb with the choke knob?....just a guess as mervin said there is loads of experience and expertise in the aircooledrdclub

what do you mean they arent coming jordan? have you rounded them off internally, or are they turning but not coming out?

aye and y'all seem to have a pet cock

@ DirtyDT, easy going temps around 160/180C, hard work temps I have seen up to 220C...all this means nothing to me but i'm learning mate @Drewpy, Had it quite a while now, around £30 ish, you have to buy one suitable for your particular size plug

yep our miles are the same as yours flyday, it was however a DT125R, more powerful than the old MX and all the aerodynamics of a barn door with those big rad scoops up front
