Hey, guys im new here and got a questoin for ya. I'm looking at purchasing a 99 600xc, and I am wondering does that have the big block engine? And what is the major difference between the big block and regular engine... horsepower? torque???
The 600 big block "was" the regular engine for years leading up to the introduction of the variable exhaust valve system. The big block has a 700 cc engine block with a 600 cc head and pistons. I have heard that the 99 was a good engine. I have the 2000 big block 600 cc engine and it has good torque and ok topend but lacks fuel mileage. The new "regular" engines with VES use a block based on the 440 engine. They produce more horsepower and are more fuel efficient than the old big block engines. The new engines come mostly with the edge chassis sleds. I would look for an edge chassis sled if I was getting started. They are lighter and handle better than a 99 sled. JMHO.
Ah well that clears up the big block thing! I would go look at an edge sled but i don't want to pay that much for a sled. I can get the 1999 at a good price, and its in mint condition, so hopefully it turns out to be a good riding sled.
We have a 1999 XC 600. really good sled. has more power then what you think. we put reed spacers, bigger reeds, boost bottle and a power pack on it. plus we rebuilt the primary and seconday clutchs. i rode it on monday when we got a lil bit of snow. DAMN i can't wait to open it up now. but you'll be happy with the XC
After the boost bottle you would need to adjust the fuel/air mixture. In all honesty I would say pass on the boost bottle they dont do a whole lot, unless that sled happens to have kehnin carbs... which i am not sure of.
As far as reading about clutching, do some searches in "The Shop" section of the forum.
I would recommend checking out EPI www.erlandsonperformance.com for an actual kit. Clutching is an art form that takes a lot of trial and error to learn so I prefer to buy tried and true setups.
Wasn't to hard to put the boost bottle on. just have to have an exacto knife to cut the hole. it should come with instructions. A power pack goes into the carb itself. not much at all. just gotta have them sit in the carb right. basically it just separates the air flow through the carb. and yes we did have some adjusting on the carbs. not all that hard to do actually.
