Description
Bred from a rich history of experienced belt builders, the Dayco XTX belt is specifically engineered to maximize the performance of the most extreme, high horsepower snowmobiles. Beating the competition on the race course is just one of many aspects that sets the XTX belt apart from its competition. Specially formulated high temperature Polymer along with the highest level of engineered reinforcement proves to perform better in belt operating temperature and efficiency than leading competitors. Its innovative break-through design of deeper cogs on top and rounded cogs on the bottom yield the advantages of ultimate flexibility and longer belt life while being a better alternative to the original equipment belt.

Vehicle Information
Yamaha Mountain Max 700 Snowmobile (1997-2004)
The Yamaha Mountain Max 700, produced from 1997 to 2004, is a high-performance mountain snowmobile designed for deep snow and challenging terrain. It consistently featured a robust 698cc, liquid-cooled, horizontal in-line, reed valve, 2-stroke, triple-cylinder engine across all model years. This powerful and smooth engine was a hallmark of the series, providing reliable performance for mountain riders. While the core 698cc engine remained unchanged throughout its production, significant updates were introduced to enhance its deep snow capabilities. In 1999, Yamaha integrated the ProAction Plus rear suspension, offering 11.5 inches of travel, and a factory-installed 2-inch track. The 2000 model further refined its deep powder performance with a 141-inch deep lug track and ProAction Mountain rear suspension. Models from 2001 to 2004 largely carried over these specifications, maintaining the 141-inch track and 2.0-inch lug height, with some 2002 models featuring a 156-inch track. Q: Are there differences between the 1997 and 2004 Yamaha Mountain Max 700 models?
A: Yes, while the engine remained consistent, there were notable changes in suspension and track specifications over the years. Please use our year and edition selector to find parts specific to your model.

| Oil System (2-stroke) | Regular check | Check 2-stroke oil level and top off as needed. Check oil injection system filter if applicable, and chain case oil. |
| Drive Belt | Regular inspection | Inspect and adjust the drive belt. Frequency varies based on usage and conditions. |
| Spark Plug | Regular inspection and replacement as needed | Check electrode for wear, measure gap (0.7-0.8 mm). Replace with a BR9ES (NGK) plug if necessary. Replace pre-season if status is uncertain. |
| Air Filter | Regular inspection | Check air filter for deterioration or damage. |
| Coolant (Antifreeze) | Regular check, replacement every 2 years | Check antifreeze level. Replacement is typically recommended every couple of years. |
