Clutching advise for 700 MM with 153" Nytro skid and track

[Frostbite]

I am putting a 153" Nytro skid and the 153" Maverick track that came on the skid on to my son's Mountain Max 700.

A Bender can is the only performance enhancement so far. It's really more of a weight savings advantage thing than h.p. gain.

The primary clutch on this tired 97 was shot (grooved sheaves) so I bought a long spring primary that was on a SRX 700 short track. The clutch is empty now so I could load it up with the 97 MM clutch weights, rollers and springs or I can upgarde to whatever you suggest.

I have some other clutch weights laying around like a set of 8BU-10, 8DN-00 and a few more. I also have quite a selection of rollers (14, 14.5, 15 and 16.5mm) and tons of different long primary and secondary springs.

I have a few helixes laying around too that might work.

Where do you think I should start with the primary, secondary clutching and gearing?

Any help you can provide would certainly be appreciated.

For sure 14.5 rollers. As for the primary weights I would look around for a used set of Heavy hitters. I have bought 2 sets in the 100 buck range. Sell off any stock weights you don't need to pay for the heavy hitters. They will allow you to clutch the primary perfectly. PM Turk, he may have a set or know where to get one. You can chase stock weights for ever and waste good riding days. I'd try to set them up in 55 - 60 gram range with good weight in the heel. As for the secondary 47 helix? Not really sure but somebody will know. You should consider mounting that track backwards. The paddles on my Nytro track folded over pretty quickly.

I would give Tom Hartman a call. He's very knowledgable, tell him your setup and I'm sure he'll have a good recommendation he'd be glad to send you. That's what the previous owner of my MM did after bringing it from Minnesota to Colorado. With Tom's clutching and gearing, all that needed done was fine tune the preload in the secondary...

Thanks guys, I have heavy hitters on my RX-1M and love them. Yes, I bet they would be a good way to go. I'll start searching for a set of HH weights light enough to use for a 700 Mountain Max. i wonder how light the weights have to be?

But................. and there's always a but.

If I were to use a stock weight setup. Surely someone has a great stock setup for 4 to 7,000 feet. Right?

as was said 14.5, 47 helix, silver secondary start about 70 degrees, lower the gearing, I liked atleast 18/42, wieghts will have to be lighter than 50-60, abu,s would work good if you can get them light enough, I like light aggressive wieghts on the mm will on everything actually. I used a set of older phazer wieghts on mine with some grinding and welding they worked great.

48 Gram base weight is what you want
