Camshafts

Will camshafts out of an 83 fit in a 99?

 

Are 83 camshafts the same as Vmax?

 

Now that Ive rolled 100,000 miles on my 99, I'd like to add a little pick me up to it.

I know the 83 are not the same as a VMax, I have 3 sets of 83's and they all match. They are not close to the VMax cams I have.

 

Get valve springs also if you are going to replace cams.

 

Don't know about fitting in a 99.

Well shoot. I thought the 83 was the same engine as a max.

 

Im looking to Vmax cams this winter but Im not wanting to spend $250 for a set of cams.

I got both heads, cams & valve covers on Pinwall this spring for $300.

 

Came from a bike with 17,000 miles on it. They where in great shape too.

 

Heads won't help you though.

The cams from an 83'VR are not the same as the cams for a VMAX. The 99'RSV uses a single Valve Spring with the rev limit at 6300 RPMS. The Heads from a VMAX will not go on a 99'RSV. The VMAX cams will fit but need the VMAX double springs to allow the engine to rev to 10,000 RPMS. The RSV heads will still have the smaller intake and exhaust valves but will stay open longer so you will need to open up the intake side of your engine, (filters, Carb. Jets, etc) and the exhause side, (Mufflers, exhaust manifolds, etc.) If you do install VMAX cams, I suggest you replace the valve seals seeing as they have 100,000 miles on them. You will also need an electronic device to override the rev limiter on your CDI as well as a way to modify the power curve and ignition timing.

You will end up with a "Quick" RSV, but certainly no VMAX because of rider position, the fairing on the front, the final drive, and the last two gears in the tranny of the RSV being "Overdriven".

I hope this info is useful,

I think that Earl laid it out very well. It would be way to0 much trouble as far as I'm concerned for the little bit that it would buy you. I already have the VMAX final and the Dyna ignition and that is plenty for me. The only other thing that I may do someday will be to go to the heavy duty valve springs. I presently have the rev limiter set at 7500 and that's as high as I want to go with the stock springs.

How much pick me up are you looking for ?

 

After 100,000 miles I would do a valve and ring job. This should help bring it back to like new condition. This wont cost that much so change all the seals while the engine is on the bench.
