Re: New Coils, leads and plug caps. Now won't start

Quick update on this one. I managed to get the floats adjusted to a correct height and the bike was running well. But there was still an issue with opening the throttle more than half, which causes the bike to bog down throughout the rev range. I took it to my local mechanic (a Yamaha specialist), a...

Re: New Coils, leads and plug caps. Now won't start

Ok, update on the bike. I took it for a ride after changing the oil today. It seemed to idle well. When riding it though it still bogged down massively when I pull the throttle anything over a 1/4 turn. When I returned from the ride I noticed a fuel smell. Took the airbag off and one of the overflow...

Re: New Coils, leads and plug caps. Now won't start

Excellent. Thanks for that. It's probably a much more accurate way of doing things compared to the way that I did it.

Thanks.

Re: New Coils, leads and plug caps. Now won't start

Update: The bike is now running!! The floats were set way too low, so i raised them up to 24mm (measuring from the edge of the carb bowl to the highest corner of the float). The bike pretty much fired straight up with the choke on and then ran without the choke within a couple of seconds. Previous t...

Re: New Coils, leads and plug caps. Now won't start

Excellent. Thanks for that. I'll try the float height adjustment and then I may just bite the bullet and buy some rebuild parts.

Thanks.

Re: New Coils, leads and plug caps. Now won't start

Many thanks for the help guys. Much appreciated. Buzzawak - I'll certainly try this method over the weekend/Monday and I'll record it. We'll go from there. Britx303 - I'm not too sure what's available in the ways of new emulsion tubes etc. here in the UK ether. I can get hold of new gaskets and floa...

Re: New Coils, leads and plug caps. Now won't start

I'm not too sure what the float valve height is. Is there a way to check this? They looked to be in good condition when I took the carbs apart.

Mileage is 43k. A full rebuild sounds expensive! But I'm sure it's worth it.

Thanks for the advice.

Re: New Coils, leads and plug caps. Now won't start

Quick update from trying to start the bike again today. Managed to get it running very roughly once again for a couple of seconds after adjusting the air/fuel mix screw right down to 1 turn out. Here's a video of the single time that it started today: https://vimeo.com/257519720 Then it just refused...

Re: New Coils, leads and plug caps. Now won't start

Update on this: So today I've done the following: - Emptied the fuel tank (fuel had been sitting in there for a few months). - Got all of the crap out of the bottom of the fuel tank and put in some fresh fuel After a few tries and more very loud bangs from the exhaust I managed to get it started for...

Re: New Coils, leads and plug caps. Now won't start

Nope, not yet. I've been away but am going to have another crack at it tomorrow.

I've leaned the air/fuel mixture out a bit and tried to start it a couple of times to no joy. Battery is currently being charged off the bike and I'll see if that affects anything when I try tomorrow.

Re: New Coils, leads and plug caps. Now won't start

Yeah the plugs were all new, as were the leads and caps. Every plug is getting a spark, as I've checked that. So I don't think the coils are bad.

I might try leaning out the fuel/air mix a bit and see what happens.

Re: New Coils, leads and plug caps. Now won't start

Update on this one: I've removed the carbs again in order to clean them a bit more thoroughly. Having put them back on the bike it now won't start at all. The bike is turning over but will not start. Also now when I'm trying to start the bike I'll get the odd massive 'bang' as the bike backfires (it...

Re: New Coils, leads and plug caps. Now won't start

Ok so the bike runs. I took it for a test ride and it rode ok. However, there is a big flat spot/hanging revs between 4K and 7K at anything over 1/2 throttle. This was followed by a 'pop' from the exhaust. This was happening before I took the carbs off to clean them though. When I took the carbs off...

Re: New Coils, leads and plug caps. Now won't start

Update: I took the carbs off and gave them a good clean (followed the YouTube video on the FZR Wiki page). The bike now runs really well on all 4 cylinders. I just need to take it for a test ride tomorrow, as I've also recently upgrade the front brakes to R6 callipers and master cylinder. Fingers cr...

Re: New Coils, leads and plug caps. Now won't start

I have no idea. But that is a good point.

The carbs were balanced and tuned and the valve clearances were adjusted about 2 years ago by a mechanic. But they weren't pulled and cleaned and that stage.
