terra tiger 16HP Briggs CVT??

[715sixwheel]

I am new to all of this and building a terra tiger I have a newer 16hp b&s v-twin I want to stick in there, what is a good primary clutch to use? Will the stock secondary clutch work with the 16 I want in there? I am not looking for speed just want power to climb hills. Any advice would be great thanks

Your Terra Tiger has weak cone clutches for turning. Putting too much power to it will just smoke them.
Sorry to give the bad news, but 16 HP is the absolute most I'd try with it. The cone clutches are engaged via stiff springs on the main shaft, I'd suggest shimming them to effectively stiffen the springs.
Your secondary is meant for a 2 stroke, but should work with the 4 stroke....you may or may not need to change out the spring in it.

Good luck with your project

Markm could shed plenty of light on this, although his is highly modified he runs a 23hp B&S in it. would recommend rebuilding the cone clutches.

Mark is a machinist, and built his own trans for it. I haven't seen it, but maybe one of these years he will bring it to Ashtabula and show it off. Hint Hint

I rebuilt one a few years ago, it was missing the main shaft so I custom made one. I put a car flywheel on it and starter just to get reverse........got maybe an hour of use on it before the clutches went. The A.D.D. kicked in, I got frustrated with it and sold it......I wish I would have just put in a t-20.

Looks like to me the electric reverse in some machines would be just about worthless in most riding conditions where you need reverse.May be good for moving machine to clean under it though.

i relined the steering clutches. its very easy and i am going to try to put another shim or two in by the springs. is the terra tiger even worth putting a t20 in? ill try to post some pics of it. i was thinking if the terra tiger don't work out how about a coot. good machine?

Mark's tiger has reverse from parts he used from a th350 if I remember correctly but I believe he still used the cone clutches for steering. He ran it for many years before he got the max. As far as the electric reverse goes, they were great to get you back 5-10 feet when up against a tree if the battery was good.

Mark ran his Terra tiger everywere and did very well!!! I remember him riding on the big hills when we had the Humphry New York rides. The main drive line still used the cone clutches. I think he added stronger springs. Maybe mark will see this post and tell the story. That Terra Tiger was a work of art!!!

Hello guys. Thanks for the compliments on my Tiger. The stock springs even if shimmed will not produce enough pressure to handle the increase in horsepower and there is not enough room on the shaft to use larger more powerful springs. So what I had to resort to was Bellville spring washers. This produced the pressures needed but the downside was the effort needed to steer the T bar. As they say you don't get something for nothing. I feel if I had to do it all over again I would look into putting a T20 in I should also add the heat from the motor sitting right in front of you is grueling especially on a hot summer day

Oh I remember that first long ride with the 23, you were complaining of the heat on your legs and thankful for the breaks in the ride, those 23's do run warm and with no firewall your eating it all.
