Partzilla Live Q&A Highlights – Honda Motorcycle & ATV Problems
Honda Motorcycle Problems
I have a 2005 Honda CRF450R that was rebuilt and now it’s pumping the transmission oil into the motor side. What could it be?
John Talley: Alright, most of the time it happens in the opposite direction. It actually forces the motor oil side out to the transmission. It could go either direction. But more than likely it’s the main seal on the right side. Now, could it be the balance? Possibly. But either way you don’t have to split your cases to get to these so it shouldn’t be that difficult to replace them. And if you’re going to replace one seal, go ahead and do them all because if one’s going to fail, the other ones can’t be far behind. You know what, 2005 wasn't yesterday, but there’s nothing wrong with having an older motorcycle …
I have a 2002 Honda Goldwing GL1800 and the gearbox is making a clunking sound when I change gears. Any thoughts?
John Talley: Alright, is it making clunking sounds just when you’re changing gears? Let’s start off with something simple. I had an 07 VTX1300 that I bought used. When I first got it, it shifted like crap. I mean, it was just really notchy and every gear change was rough. And I thought I would have to go in and rebuild this stupid transmission because somebody was obviously really hard on this machine and did it dirty. Well it turns out they were using an oil that I don’t want to mention, but it wasn’t what I preferred. And just for the heck of it, I changed it over to the oil that I like to use, which is that gold HP oil from Honda Performance fluids. After the second change, all those noises went away. So before you go diving into the gearbox of that GL 1800, which is not fun to drop out the engine … go through a couple of oil changes with that HP4 semi-synthetic oil in the gold bottle and see what that does. I mean come on, that’s 15 or 20 dollars of oil and it’s worth a shot. It worked for me and I kept the bike for another three years and never once had to open up the cases on the thing.
Honda ATV Problems
I have a 2005 Honda TRX350. I went to start it today and I have no ignition light and it’s blowing the main 30 amp fuse. Any suggestions?
John Talley: That my friend is an indication of a direct short. If you don’t have anything turned on and you’re putting in the main fuse and it’s popping it like that, something is definitely going to ground. So my first order of business would be to start picking over your wiring harness and make sure it hasn’t been chewed on. Because I’m betting this may have been left in a barn. Maybe an outside storage area? It’s been cold and critters tend to make nests in our machines, and they love using insulation off the wires. But if and when you’re able to run this down in the future, you may want to spray it down — you’re going to think this is a little nuts — with hot sauce. They don’t like that. Worst case, you can add in some poison to deter these little vermin from attacking your machine.
