Bought a 78 XS650 SE and intend to stick on a TC Bros hard tail. Someone told me I might have a hard time getting it registered with the Ministry of Transport here in Ontario when it is hard tailed. He suggested I get it legally registered as per factory specs then hard tail it after. Anyone...

Hi all, I flooded my bike yesterday morning and pulled one of my plugs to check how bad the bike was flooded. I made the mistake of giving the bike a few kicks with only one spark plug connected. Now when I plug them both in I don't get any spark. I also tried new spark plugs without any...

Inherited this '78 from my dad because he never had the time to get it going. So instead of letting it sit, he transferred the title to me. Since it's so far gone, I decided to go with a brat bobber. Love how low they look and they are just cool to me. He had it running, although it was not...

I have an 82 model, PO redid the wiring (its kind of atrocious but I will be replacing it once I make sure everything is working properly) It will start, run and drive until the battery gets low (and run bad after some distance, I think the coil is going out/getting hot.) I can not get it to...

Hey folks. I'm swapping to Hugh's pma right now. And I'm out of ideas where to mount the Recifer. I thought about putting it on the little mount beside the upper motor mounts ( see picture) I know it'll get enough air. But what about the heat from the engine and the exhaust? Did anyone...

I'm looking for different seat options that will work with the monstercraftsman brat kit. I want a seat that kicks up in the rear more than what is offered with the kit. Has anyone found one that works or have any suggestions without having to modify the kit too much? Thanks

I'm thinking about exhausts and would like to install a 2 into 1. Mike's is selling this header and it looks nice. My other thought would be to have a custom 2 into 1 buit to my desire, however this looks like the easiest option. Has anyone installed it? Any thoughts on how it fits, how it...

I reasently bought a 1980 bobber and was looking for parts and info on my new toy. I ran across this site and have found the only place i need. I ordered gaskets and filters on Wednesday and they arrived on friday. I had ordered breaks from another site over 2 weeks ago and they came in on...

So I'm still not exactly sure what happened but in January I called up Ardcore and got an order in for a DIY Ardtail. Was told the lead time was 6 weeks, which was fine seeing it was winter and I live in MN. I waited about 8-9 weeks before contacting them again and got an e-mail saying "sorry...
