Speaking of breakes, I've tried a few different attempts to improve the brakes on my 89 Ovation. I'd love to go Hydro and have purchased a newer Yami hydro systen, just not the rotor!
Anyone have any ideas?

better brakes on an ovation? must be a ripper. all kidding aside, put on your creativity hat and think about fabricating bracketry to hold the caliper. thats the key.

thought about this years ago on the vmaxs and exciters but never followed through. the vmax4 guys had a setup at one time and utilized the stock rotor. you may research that a bit for some ideas. at one time there was a guy selling the bracket.

another option is a wilwood driveshaft mounted caliper and rotor. see those alot on the drag sleds. check out wahl brothers racing.

I did make a bracket and adapted a Wild Cat caliber, just no luck?
And Yeah it aint stock!

yamadad4

which part didnt you have luck with? getting the caliper to work on the rotor or something else?

kccats

When I had the WC caliber it didn't reall stop any better! I think I need a larger rotor as well?

yamadad4

vented rotor? if the wc has a dual piston and you correctly blead both(i know you did), you heat dissipation may not have been sufficient enough.

It was an older cable system!
I guess I'll try and find a larger rotor that will fit the Ovations shaft? Any ideas?

yamadad4

dont anticipate any gains from one cable system to the next if i understood you correctly.

as you know the gain comes from the hydraulics. as for rotors, look into any rotor from yamaha 2 strokes 97-05. basically same design amongst all years, the variance is in the weight.

Would it be easier to replace the entire chain case, rotor and hydro?

yamadad4

depends on what you have access to.

in my opinion it would be far easier to adapt a new different rotor to the existing jackshaft. unlees i was building a full out mod, and the ovation isnt a platform i would choose for such, i would look for a cheap rotor at your local scrap yard or ebay.

sorry, i have none available.

Im hopeing to find what ever I'll need from Hat Days! Can you off hand tell me the size of the shaft and the count on spline or key way?

yamadad4

would be easier to adapt hubs to rotors as yours is kinda model specific on the jackshaft.

if your rotor shopping, shop for 98 and up srx or any viper.

kccats

And what about the chain case?

yamadad4

chain case is pretty much the same as the phazers and a few others. in my opinion it would be very difficult to alter or adapt a new one in there but time and money are usually my limiting factors as is the labor ratio to equal end results.

take a look at your existing brake rotor and how its mounted between the chaincase and the chassis. your rotor should be about 6" diameter, maybe a little larger. shaft will be a bit larger than 1" and it uses a keyway.

i have a jackshaft off a proaction sled in storage, i need to find it and compare diameters and fitment with the older stuff.

whens haydays?

kccats

Sept 8&9 Have you ever been? It's a blast and to say its huge is an understatement!

yamadad4

never been. its a long ways away but something i always thought i would enjoy attending.

i could probably load my enclosed with all the parts and snowmobile related crap i have and make a killing at a venue such as this, including fuel!

i was teasing the wife a few weeks back about selling all the snow stuff at haydays, my kids got a little concerned as the sleds they ride were included in the inventory. pipe dream.

for what its worth, i pulled out an extra proaction jackshaft i had laying around along with a phazer brake rotor. direct fit, but i would use a keyway for 97 and up sleds vs the phazer one. a bit more meat there.

next issue to come to mind is the rotor diameter. i have nothing to compare to at hand on from the proaction. keep in mind if its larger than the 6 1/8" diameter oem rotor on your ovation you will be customizing the top of the chaincase to allow for fitment. couple theories here.

I emailed a guy that I had gotten a Yami Hydro brake set up from a coupla years ago when I started this project. It has a second lever (kinda) that like flips over for the E brake? Any Idea what it might be off of? I guess I'd be better off with the complete chain case as well as rotor?
As for Hay Days, some of the Junk will sell the fastest! I know if I would load everything I have in the big trailer I could come out with $20,000 maybe! The amount of money that goes threw hands out there is stagering! I usually spend $5k every year!

kccats

From what I have been able to investigate, the Hydo set I got came off of a 97 Vmax XTC? Would it be possible to find a complete chain case with rev and rotor? And do you think I could make it fit?

yamadad4

that style was introduced in 97 and wasnt model specific if the sled had the pro action chassis. they ran this style for years on both the 2 strokes and alot of the 4 strokes.

you would be dealing with several issues adapting a newer chaincase into your chassis, but i guess just about anything is possible. fitment to the chassis as well as shaft adaptability come to mind. they didnt change that chaincase much over the years on the pro action sleds, but it is considerably different than the one on your ovation. you may have better fitment choices for the reverse theory from the ventures and vikings from the same year as your sled. should almost bolt on.

from there, i would play with the brake system as a seperate entity. one thing that will make that system easier may be to abort the parking brake cable and lever and make your own parking brake with a pin. thats what i did.

So a 97&up Venture or Viking with rev and the rotor would be what I'm ideally looking for?
