Had the bike out the other day for a ride and had just left the coffee shop. When I pulled up to a stop sign the left bank backfired and the bike was only running on one cyl. I managed to get it home on one cyl. and pulled the plugs out to check compression. It was good and when I looked at the...

Had an AGM battery in my '75 650 for a year and a half. Went to start the bike this week and it was dead. Of course it was out of warranty. It cost me about $140 when I bought it. It was on a battery monitor. Ordered a new yasua AGM on line for $39.00 shipped. Has anybody had any experience with...

Probably been asked before but my memory isn't any longer than anything else I've got. Does anybody make a stronger spring for the starter gear. I thought I remembered somewhere at one time there was a discussion about this. Also, has anyone ever changed the angle on the starter gear teeth to...

Ok guys I have looked at about all the rear shocks available and would like to hear from you on what you're using and why. Most of my riding is single but the wife rides with me every once in a while. No hard riding or street racing. Just knocking around most of the time. The bike has a set of...

Has anyone here used JBM industries for replacement diaphragms on their 650s. If so how did they work out for you. My old 650 has a hole in the left carb diaphragm and I don't really want to buy the very pricey new slides.

Anybody here have any experience with the AGM batteries in their 650 Yamaha's. If you have what are the good and bad points with these batteries?

When I log into the forum the first thing I see in the garage section is several pictures of a blue cafe racer. What have I done wrong and how can I fix this. It's not a bad looking bike I'm getting kind of tired of looking at it.

Why do people throw cut grass into the street when they mow their yards. Our little town has ordinances against this practice but no one will enforce it. No less than four idiots did this last Friday between my house and down town. I don't guess they realize how dangerous this for motorcycle...

Looking for a place to purchase a new ign switch for my '75 650. Would like to have one with seat and tank lock with it. Posted via Mobile

Just recently developed a ticking noise on my bike. Having made some changes on the crankcase vent system this year I feared that I had created some excess pressure in the crankcase and may have blown a head gasket. You know how you always think the worst. I changed the vent system back to...

I've looked all through the carb section and found nothing about surging. At 50 mph I get a slight surge. Engine pulls fine at all rpms but when running a steady 50 mph I have this surge. Any ideas. This is a '75 650B. Everything stock. 24000 miles. Thanks in advance.

Does anyone have a special fix for the starter problem on our XS's. kinda getting tired of replacing the gear every year. Not really that big of a deal just would like to fix it and have it stay fixed.

Finally learned to post pictures I think.

What purpose does the foam before the air filter serve in the airbox besides muffle air intake? Also are the metal covers needed on the carb holders? This is on an XS650B. Thanks in advance.

Just got my new carb holders in from MikesXS last week and installed them this weekend. Have been needing them for a while and finally broke down and ordered them. Service from MikesXS was perfect and parts fit like they were supposed to. Got every thing together and realized that I needed the...

Any ideas where to find Carb holders for a '75 XS650B. Mikes XS is out of them and I could use a set. Also need a source for the starter gear.

I need a low backrest for a Yamaha luggage rack on an XS650B. Would prefer to have an original Yamaha part.
