Side cars never caught on. Main reason is that your bike is no longer a bike so to speak. That is, it rides differently.
The site he gave you is for a very large forum aimed at the sohc in line 4 bikes, 350, 400, 500/550, 650, and 750.
I used to frequent the site a lot however; while some of them do have a lot of good info, you pay for it with a lot of egos. Some are so bad that even when they are wrong, they can't admit it, even if you can produce proof, they just block you. Ask me how I know!
It was pretty sad for me to leave, I was on there for over 4 years. I chose the name re-run more or less to symbolize a new start. This site is much smaller but since I took it over back in March, the amount of info available on it has increased dramatically from what it used to have. With the constraints I have, I am quite proud of it. We keep slowly gaining members but many are not regulars.
So I am more than happy when a new person drops by.
Like I said though, the sohc4 site has a lot of good info. Info that is not here, yet anyways.
I understand if a person goes there. When you need help, you need help.
The ride IS the adventure. The destination is just to get gas!
