Hyvo gears or not?

[1M800]

Earlier I was wondering about changing gears in my King cat, now I have to I have my chaincase apart to swap tracks and I found that it's geared for 0-3000 feet. It has 19/40 gearing I would like to go to 19/43 or 19/44 hyvo setup. The only problem is that I have mechanical reverse, is that and hyvos compatible? Thanks

Maybe geared right you will actually be able to climb something!:beer;

Chain pitch.......

2-zeros is that a 72 or 74 pitch chain? How do you remove the cover and not have a mess of oil in the bottom of the belly pan? I was thinking of putting it on its side, And removing, Then cleaning up the case before install. Unless there is a better way? Oh, What are you running for lube?

Thanks
Mike

I am not exactly sure, I'll have to do some checking. I think it is a 74? But don't want to give bad info. Also for the draining of the oil? Kingcats have a drain plug, I just pull it the day before I want the cover off. No mess at all. It makes it very easy to change the oil also. Happy New Year -00's

I wonder if a larger dia. roller on the tensioner would help to keep wear on the chain down at the dogleg? Looks like a tight bend there.

1M800 have you got that wreck of yours going yet? get anything figured out on your DD:beer;

Yes, 74 pitch and I do believe it is a perfect pitch assy, Meaning that the chain will be tight and the tensioner will be backed all the way out. "Happy New year to all of you out there"

Mike

you have to give it a little tension but not much.

Yep got one it. Got my Digitron EGT's hooked up. Just waiting for my 13:1 domes.

2zeros I changed gearsets today, No drain plug like the kings, So siphoned and worked great! Also mine has a second tensioner on the straight side of the chain with a spring connecting the two. Did the King or '04's and later delete this for some reason? Original chain/gears look perfect, But I see the size difference of the pins and links. Both chains weigh exactly the same.

Mike do you have reverse in your sled?

 

[1Mike900]

No, I have a 03.5 151 mtn. I noticed that the pic had no left side tensioner with a double spring connecting the two. I was wondering if it was really necessary, Or if AC removed it because of problems? I have never seen a Reverse set-up pic.

Thanks

just take out the auto adj side and put it in the round file. just use the one on the right side.

 

[80arrow]

I would have posted a pic of mine, but I'm not smart enough to figure out how and I just got it put back together. One other question tho, does a new chain and sprockets make a little noise (about 3/4 mile) until they mesh with my existing idler sprocket? I hope so because mine did and then it went away.

 

[1Mike900]

80, I would assume it would take a little until it seats, But don't remember any sounds when it was new. '76 so this extra weight and bearing that I am spinning was found on the 03's and earlier? So you see this of little to no usage, Was just wondering if it was to keep the tight side from slapping around when you let off the throttle or something? Reminds me of the old El Tigre adjuster blocks in the early 80's. Little or no usage then in the parts bucket it will go, Just another bearing to replace the adjuster one with!

I don't remember my new ones making any noise in my 1M...but as long as it went away I wouldn't worry about it. :beer;

I'll ride it and if it breaks then I'll know what it was, maybe.

 

[KMMAC]

80arrow did you pull up on the chain as you adjusted the tensioner? I would double check cause if the chain links were not meshed it could cause premature wear.

 

[80arrow]

I went with the 18 top, and my chain did not last the whole year. After I had another problem I noticed a couple of broken links. I am not saying not to, but keep an eye on the chain. I went with the hyvo setup 18/46. I have been told the hyvo setup is the way to go. Check this out. 1st pic is silent chain 2nd one is 18/46 HYVO setup.

On my sled there is another gear on the left side between the top and bottem gears, with another guide on the outside of the chain where the bolt is in the pic. This was the only gear I didn't replace, thats why I thought it might take a while to "mesh". No I didn't pull up on the chain when I tightened the chain.

 

[2zeros]

That stupid auto adjuster................

I got rid of that! It would help the chain not get too loose if you never adjusted it. The guy who keeps his chain adjusted doesn't need this. Some models came with it, and some didn't? I gotta ask if it is needed or not, if some models don't even have them? -00's

 

[80arrow]

I think that it is part of the reverse cr@p. Or the actual reverse gear.
