Has anyone used 1500 carbs on a four cylinder wing?

Remember the Valk engine doesn't turn as much rpm as a 1000 engine. They may work very well from idle up to say 7000rpm or so. But after that they be choking the engine some.

Robin1731 you said "Remember the Valk engine doesn't turn as much rpm as a 1000 engine.

I might have had my wing bouncing around 7,000rpm one or twice. My thoughts on this is
the story is told between 2900 rpm to 6500 rpm

The rev limiter on the Valkyrie kicks in at about 7500rpm I seen other Valk owners that have
done away with the rev limiters and take them up to 9000rpms... I think the carbs have the
nades to handle the GL1000. The stock wing fuel pump might be a problem... a little money
will fix that

Past 7,000 RPM?

On any regular basis? On a GL?

Someone is riding the wrong bike...

Maybe running a 1500 at 9k is one thing, probably could be done, but aren't you likely past the torque bands? My gl1k can run there but it is past the surge and wants the next gear. I commend anyone for trying it though, and there are plenty of people who like improvements for their wings. I'm guessing it might bring more low end grunt, but like Robin said choke itself at the upper ends.

My point was the stock carbs on a valkyrie will keep up with the fuel demand up to 9000 rpm
but the rev limiter kicks in at around 7,200rpms.
I will post what comes of this carb retro fit, just not able to finish this in a day or a month my
day job has me busy 10 hours a day 7 days a week... AND I FOR ONE NEED MY BEAUTY SLEEP

Stude,

Are going to Inzane?

I hope to hear that your carbs are working perfectly by that time.

I need to get my 1000 running, and I happen to have an extra set of Valk carbs to throw on there.

He must be still getting his beauty sleep. He has not logged on in 8 months now.

Just not enough hours in the day for BEAUTY SLEEP.... and that dirty four letter word W O R K gets in the way. Hope to be back on track with carb project soon.

Problem is using a CV Constant velocity carb, they are very slow to activate.

That Would not be my first choice on a 4cyl. oldwing, not even for a GL1500, they are not the best choice

Hi, the 1500 carbs would have to be fitted in line with the engine and not across (has fitted standed in a 1500) has they are to wide for the frame.

I think he was referring to the original question.

Yes , I looked in to fitting the standed 1500 carb to my 1000 but they are too wide to fit in he frame.

I was thinking more of mounting them individually, outside the frame, with manifolds as per Randakk's Weber items but with a neck instead of a flange mounting.

What is the size of the bore?
