Conical valve springs - option for those afraid of beehives?

[Hillside Motorcycle]

I install hundreds of the AV&V .650 springs every year & don't see any problems.
Not ready to yell 'the sky is falling' yet.

I agree.

Will the conicals become the norm do you think? As in replacing beehives and straights in our world? I know next to nothing about them but reading on here there seems to be a gathering momentum in that direction.

Marketing trends matter as do stock levels.

No, no, it isn't gather momentum, it's slowed.

    I see S&S is now supplying conical springs in their bolt on 124 kits for the M8's...it looks like the momentum is picking up.

Those are beehives despite them being called conical. Marketing

   I had to make a call to S&S when I got that e-mail with the above posted pictures to ask if they were supplying beehives...or conical springs with their 124 bolt on kit. I said to him that the picture you sent me the springs look to be beehives. The response he gave me was the picture does show beehive springs...but we are going to supply conical springs with our 124 kit.

Not in top levels of racing, I know that for a fact. HD performance lags between 10-30 years on the open market, depending on subject matter.

Has anyone saw or used the Manley 99270 conical kit?

[Hillside Motorcycle]

S&S has had AV&V beehive springs(and valves) in their heads, and has sold them in kit form for several years now.

[Don D]

Has anyone saw or used the Manley 99270 conical kit?

I have a few sets, they are beehives

Sneaky wording.

[dave brode]

Are the Manleys in that list USA made?

[Deye76]

Never mind found what I was looking for.

[Don D]

Manleys box doesn't show country of origin

[TorQuePimp]

Manley's springs are made both off shore(South America) and pac makes some

The 99270 are offshore.....I use a lot of them zero issues other than I can't get 300m retainers for them anymore
