Just bought a grizzly 660, don't even have it yet and already looking to improve it. Thinking about 27 inch aggresive tires/wheels. Any problems with this? Also, anything easily done to increase performance (without sacrificing durability). Thanks for your input, I'm new at ATV'ing.
The bigger tires will decrease the performance of the bike. Most people have to increase their power when they upgrade tires in order to retain the stock power. A K&N filter and jet kit will keep the performance. They make several pipes for the grizz that I'm sure will be helpful also.
really appreciate the info...I'll probably have 2 complete sets of tires/rims then. I'm unimpressed with the stock rubber setup on the Grizzly. Will also do the filter. Jet kit?? Does this sacrifice anything else?
A jet kit has larger main jets for you to tune the carb in. Any time you change the airflow situation (filter, pipe, etc.) you need to rejet the carb for optimum fuel/air mixture. Clutch kits are also very popular for big utes. Have the dealer/mechanic do this for about $200 -$250. It is worth it for the extra acceleration.
