I was wondering what I all need to convert my 02 zr800 efi to a standard length 121 inch track with 2 inch lugs. I see that camplast makes a track for this application that is notched out for the heat exchangers. I wanted to know what drivers I would need and what gears to use for this. I already have all the clutch parts for higher elevations.

Thanks for the help,

chuck

Last year I installed a 2"x121" in my buddies '00 ZR 600. We ended up doing a direct replacement. He rode it up in the mountains and had no rubbing, nor cooling issues.

I don't gurantee it'll work for yours, but you never know...

Seems like it would function more like a ditch-witch....

Seriously, 2" paddles without the floatation of a long track? wouldn't that just dig a trench?

I put a 2" 136" track on my '03 ZR8 last year and had no problems with rubbing on the front cooler. I can say that it is within 1/2" of hitting however. I don't know if that could be a problem if I picked up a stick or chunk of ice, but that hasn't happened yet. The track is notched for coolers so I also had no problems there.

I have run a 1.5" aand a 1.4" the last two years, somehow ripped the lugs off of both tracks down one side/edge each time mostly trail riding with some offtrails excursions. don;ty know waht ripped them, but I am sure it had to do with picking up something due to lug height.

I'm running a 1.6" on mine, and there are only 4 lugs left on the left side/edge. I know how mine got ripped off though...that's the side I carve off 99% of the time, and I've done it quite a bit in low snow conditions. Tall lug + dirt = Not Good!

This would just be a one trip to the mountains a year otherwise I would longtrack it, I normally ride in minnesota and wisconsin were 1.25 lugs are more than enough. I have heard that 2" lugs worked fairly well with a 121 on the 800. I figured on having to change the drivers out for the next size down. Would I need to change gearing for the increase in lug size? other than what it says for higher elevations on the air box?

thanks,

chuck

I don't know how a 2" would fit in there, I ran studs sized 1.575" on a 1.4" track and made some contact with the heat exchanger on my 01' ZR800. I would think you would need to change the drivers for a 2".
