Ordered a 1021 spring and 18g weights. Going to 30" tires. I have the tires already. What can I clock the secondary to until I get the parts?

Just purchased a 21 model 800 yesterday. Put it in the shed yesterday had stuff to do. Jumped on it this evening and took it easy just riding around the yard. 5 mins in the coolant temp warning is going off. Checked coolant and added 1/2 gallon. Ok whatever. My son wanted me to see a trail he had been working on next door so I followed him in. Nice and easy nice wooded trail.  30-45 mins in same thing. Let it cool down he went back for antifreeze. Topped it off another 1/2 gallon. Took it straight home and put it up.  Rechecked coolant. Low again. Noticed a substance hitting the floor. As a mechanic I know this ain't good. Pulled the dipstick and there is all my antifreeze. 3.5hrs on machine and only 12 miles. Never been over 30mph and never been hammered on. Wtf!!??

I'm having the hardest time finding info anywhere online of what freakin weights and springs folks are putting in their 600's to wake em up. Been searching for days. Watched 4 million videos and read countless threads without any information. I know adam at airdam is putting together a kit of weights and springs for these but its $190. All I want to know is which weight and which spring. Contacted people on YouTube who have done the airdam kit but they have no idea of any weights or spring numbers. This thing winds up a ton before it moves and just feels spongy since day 1. I'm after that instant throttle response and bottom end grunt as kost trails I ride are tight and turny some some and some hills. Machine has 28's on it so that's another reason. HELP!!! NEED PART NUMBERS!!!
