    If you can swing it, a 144 Camo Crossover get 2 thumbs up from me, myself & I. I was able to squeeze that 1.5 into a 96 XT6 w/ 8 extro drivers.

    The gearing in the Venture TF 153" ( 1991-1998 ) is: 17/38 ....which gives a gear ratio of 2,235

    only holds 1/4-1/3 of a litre if I rember correctly as it is the same chaincase as my et410. the ventures had a dipstick though where the et had to have a bolt removed to check the level.

    Question Help with clutching... ?

    Anyone know of a useful clutch set up for a 144" track in the Phazer-I/II chassis ?

    * Chaincase gearing: 17/38
    * Riding height: 1300-2600 Feet.
    * Rider weight: 150 lb.



    Today with the stock clutch parts the engagement is 2500 Rpm
    and I would like to have engagement @ 3600~4000 Rpm.
    I want to have a smooth engagement.

    I have not yet take apart the clutches, but according to the parts list this is the parts:

    1991 , Yamaha Venture-480 153" ( YPZ clutches )

    # 85T-W176A-00 , Clutch weight.
    # 90501-527E3 , Primary clutch spring.

    # 88N-17684-00 , Helix.
    # 90508-50746 , Secondary clutch spring.

    Since I'm not a Yamaha guy I do not have a clue what the above part #'s mean in reality !

    Also check under the hood for oil amount, there should be a sticker listing plug, air fuel adjustment, etc.
    I think you could get away with 1.5" track easily with 8 tooth drivers, possibly a 1.6" cobra....1.75" might be pushin it.
    You might have to switch to 7 tooth drivers for a 1.75" and if you want a 2" paddle you'll need to switch for sure!

    Question Clutching with 144" track

    with stock helix and Yellow/Green secondary spring set in B-2 is a great all around trail set up.
    Will this work with 17/38 gearing and 144" track ?
    Will this give the sled a smooth engagement ?
    Engagement Rpm ?

    Primary clutch weight: # 87F-W176A-00-00
    Primary spring: # 90501-55388-00 , Yellow/White

    Part # on the Helix since there is many different listed for the Phazer-I/II ?
    Part # on the Yellow/Green secondary spring ?

    Is there any primary clutch springs chart for the YPZ clutch ?
    Is there any clutch weight chart to get hold of for the YPZ clutch ?
    Is there any Helix chart to get hold of for the Phazer-I/II secondary clutch ?
    Is there any secondary clutch spring chart to get hold of for the Phazer-I/II secondary clutch ?


    Many questions but I trying to learn !

    Default Feel free to comment....

    I found this in an old post on another snowmobile forum:

    Quote:
    Retiredpop
    I have been running a ( 1991 ) Phazer-II LT 136" with AAEN single can pipe for a couple of years.
    My setup is as follows:
    Gearing: 17/33 with 7-teeth drivers.
    Track: 136"x15"x1.5"
    Primary has 8VO weights.
    Wht-Lt.Grn spring , Part # 90501-555A0-00 , spring rate 2.85 kg/mm preload 26 kg
    This gives a nice low engagement so you don't dig a hole on takeoff in soft fluffy snow.
    I really like the Wht-Lt.Grn in my Phazer.
    Secondary setup I have a Grn/Yel spring run in B2 position.
    I would highly recommend the 39 degree helix , Part # 88R 17684-00.
    This probably made the single biggest difference to get it operating at the preferred 7200 rpm for the AAEN pipe.
    It holds at 7200 rpm now when climbing or in heavy snow.
    Previously with the 47 degree stock helix it would never go over 6800 rpm unless on hardpack.

    Sled is ridden usually between 5000-7000 feet.


    Comments on the above ?
    Are any of the above useful in my project ?
    ( Remember that my sled will be used in 1300-2600 Feet, with 144" track, 8-teeth drivers and to begin with stock exhaust )
