dropping your sno bike on any model, this is what I do on my 5 lowered bikes.
1. get out the note book, set the bike or snow bike on level concrete and identity a reference point on the front of the bike, say the lowest triple clamp bolt, put a dot of yellow paint on it. measure that distance from floor to point( vertical measurement, use a square if in doubt ) , note that.
In the rear on bikes I use seat bolt on the oriental bikes or other 6mm bolt head around the back of the seat, mark it and write that that down.
2. On a bike I use a ratchet strap to collapse the front forks until my reference point is 3" closer to the ground, measure how much your fork has collapsed, placing a magnet or zip tie on the forks un collapsed then note the distance the zip tie moved. The travel distance is how long a spacer your will have to put in the front forks. In our snow bikes, all you have to do is mod the spindle and move the ski mount up three inches.
3.In the back after writing down your reference point measurement, take the springs off the shocks, put the shocks back on, put a zip tie or magnet on the shock shaft tight against the shaft seal, then collapse the back of the bike 3" and again, write down the amount of shock travel, thats how long an internal space you need in each shock. In the back I would try this with the forks extended and then collapsed 3" and see if there is a significant distance difference.
Shock springs on an ARO once shortened, you can save money and buy 8" 1 7/8" ID 200 lb or appropriate springs off Ebay from
South WEST SPEED or southwestspeed.com . $50 to your door.
I have been running my older TS kits and Riot kit with 3" spacers in my font fork and no modification to the TS shocks length wise. You do have to make significant change to your strut length to get the ride quality back you want. The results are very noticeable, lighter feeling more flickable bike.......if you can say flick around a KTM500.
I am doing two dual sport /dirt bikes the last few days of staying holed up in my shop. 3" lower, DR Suzuki and WR450 Yam. On both these bikes, new seals on the fork and shocks while apart. I cut the springs shorter with an abrasive wheel, no use getting wookie about buying more springs. The DR fork springs are too soft, but lots of new take out XR fork springs for 20 or 30 bucks on Ebay. Use the RACE TECH website spring rate programs to figure what spring you have and what springs you need ( bike/atv ect.) and what other brand of bike use the same springs when searching for springs at a good price.
