The Cherry Fizzer

See I discussed this with my mate and his brother last night, but they ruled it out as the pumps on bikes usually run at 4 or 5 PSI. 6 absolute tops. But it having a but of trouble running ATM. But I think that's a combo of almost no fuel, old fuel and not having a good squirt in god knows how long!

Plus there is also the issue of the carbies needing a sync and possibly needle and seats.

But it needs a good squirt to determine that.

 

Also finished up painting the inside of the fairings. Old:



5! Coats of satin black later:



Betterararer

Will be touching up the masking tape lines tomorrow.

 

Alrighty K&N oil filter fitted: part non KN303 as seen by the box in the background



Ok just removed the plugs: notice the difference?



That's Number one cylinder (left hand side while seated on the bike). Just remember that these are brand new plugs and only been started a handful of times. Looks like that carb is flooding I reckon.

 

No I don't I think I can find some more off the old FZR ducktail fairings and possibly buy some if needed. In desperate need of the bolts though.

 

It's definitely something with the carbs. Pull the choke or throttle and it floods and the zorst note changes to really really flat. Both off and it wants to fire so bad but just can't get there. May have figured something out choke off and the throttle turned maybe 5% or less and it fired. That might be the case of just enough fuel to feed the carbies and not enough to flood number one. My mates brother owned a Virago 1100 (that he sold years ago and bought another one last year) and said the 1100 was a temperamental bugger. Only he could start that bike. You had to have the right choke/throttle combination on any particular day and it would fire first time. Anyone else tried it it wouldnt even fire.

In saying that all of this we had been cranking it awhile until then. That has been the process lately crank, switch off, leave it sit, turn on, crank, rinse and repeat. Finally it fires. This time, we even played with the idle screw. After that when its hot, its virtually a quick push to start it. But I think there is even a clue here. Leave it run for a minute, then the revs rise around 1000 or so, and the idle cleans RIGHT UP. It sounds smooth, clean and throttle response is crisp and instantaneous, revs and drops sooo easy. Until then, its labouring like its flooding. It needs a good squirt to see whats happening on the road.

Thanks for the info Maelstrom. I will definitely look at those at a later date. Are the last two options able to be played with without a carb removal?

As much as I want to put this bike on the road, finished, nothing to touch, there is a time/money/practicality issue here. My mate has made it clear he no longer wants it in his garage, and even by my standards its been in there way too long, sort of like the friend who comes to stay the weekend and doesnt leave for six months, Ive had that an know what I am thinking at the 6 month mark. The subtle hints are dropped and directness takes over. The gearbox on my car isn't looking the best, so I am babying it, and there isnt any spare cash floating around in the next few pays after this one. At least not enough for a carby rebuild/sync/replacement. Apart from me wanting the bike on the road this week, I NEED it on the road this week.

Unfortunately, that's just the way it is at the moment, and I really have no choice but to roll with it.

 

It's funny you should mention all that, we use a 1900 amp jump starter after the first few tries, and you can definitely hear the difference in turnover speed from that (obviously).

And also your dead in about the "finger off, best time to start" Everytime I lift my finger it coughs and stops and I think "damn that was close, I'll give it another try". I thought it was just playing with me!

As for the idle cleanup after a minute or so, my mates FZR 1000 used to do the same. Start a little flat an then the secondaries come in and the note would change. Very similar to that.

 

Walked in this morning, hit the starter. Fired first time. Though after a few minutes of idle it rises, and stays at 3500 or so. Turn the idle screw down, and that lowers the idle. Turn it off, come back later, hit the starter it fires, idles very low, sometimes conks out, so I up the idle a little bit, rinse and repeat.

 

Forgot my phone today so couldn't log on and couldnt fire out questions. Or take progress photos

But a wrap of the days events.

A few minutes after seeing your vid GI, I went out and checked mine. Thats when I noticed that its not the Fuel pump I can hear, it was the exup servo going. Now I pulled out my old 2kr one, grabbed my one off (plugs and the cases ARE different, however internals are exactly the same) pulled them both apart and pulled all the stripped teeth out of the box from mine, (the actual gear was missing) replaced it with the gear from the other, presto! working Exup! Does its little check as per your vid Grey, then start the bike, rev the motor and and it moves with the revs, up and down as it should. WOOHOO.

GI. You are an absolute legend. I honestly dont know how I could be getting some of the important finicky stuff done without you. A genuine, genuine thanks.

Its now idling better. Just sits just under 3k, but rev it and it stays idling at 3500. Turn it off, start it again, stays idling until you rev it again. Its not a sticking throttle even pushing it forward doesn't do anything after the rev to die it down.

Other things completed today:
Swingarm painted, footpegs and linkages back on, all from being painted, all alloy stuff has come off and is starting to be polished (fun times there!! Especially the footpeg guards!) Most bolts have been painted for a bit better presentation. Now its polishing and re-assembly.

Pics to come.

 

Ok. Sitrep.

So today started with a few bits an pieces tidied up. This included an earth wire near the EXUP box that was dangling. Then went ahead and started to sort out this idle issue. Took off the airbox, played with the throttle cable and sorted out the play in it. Reset the idle screw, and the adjusted the carby adjusting screw (I think that's what it's called. It's the screw next to the carb linkage bracket that the throttle and throttle return cable connect to) That sorted out the idling issue by the looks of it. Started it a few times and reved and seem to come back down to where it should. Fingers crossed this solves this issue until I can afford to overhaul and sync the carbies.

Took off mudguard ready for the tyre change tomorrow.

Then spent the rest of the day buffing and polishing. From 3pm till 8:30pm:

Teaser pic:



Just have the stator cover to finish polishing and the handlebar tree

I also have new found appreciation of the guys who do this professionally. It's painstaking work!

So a few more shiny bits to do tomorrow, but of a going over, check, recheck and triple check all my work. Then fit fairings and it's ready for RWC.

I have also decided to push back the road worthy till Tuesday. Gives me an extra day to work with a little more breathing space, and I can't pick it up till then anyway busy from Friday till Monday.

Real life calls!
