Yes, I looked at it. The Big Reds are identical to the US Fourtrax 300 models, except the US models don't say "Big Red" on the gas tank. The US models say "Honda Fourtrax" on the gas tank. Those are great 4-wheelers. Honda sold those for 13 years in the US. No doubt, the best 4-wheeler they ever made.
ive read alot about them people seem to think there unbreakable! thats why i bought it!! this clicking problem gonna be expensive??
The ring and pinion gears are the most expensive part if they're damaged, but sometimes you can find a used diff on Ebay cheaper than you can buy the gears. The gears are around $400, but you may find them cheaper on Ebay. If the gears are shot, then the bearings will also be shot and will need to be replaced. From the Honda dealer, the bearings and seals will cost around $200, but you can find bearing kits on Ebay for less than half of what the Honda dealer wants for the bearings. Installing the gears is the hard part. The ring gear is easy, but you need special tools to install the pinion gear. Also, the needle bearing that the pinion shaft rides in is hard to remove. I believe the easiest, cheapest route would be to find a good used one on Ebay.
Before buying a diff or any parts, make sure the diff is actually the problem. Verify the noise is coming from the diff and then visually inspect the diff to see what the problem is. If it's not the diff, the problem might be a bad axle. If one of the CV joints is damaged and tries to lock up, that will also cause the ATV to pull hard to one side.
