How did you get here?

I found the site through Reddit r/fixxit group and through googling “xj650 maxim forum” because I’m looking for help on my xj650 maxim. It was starting yesterday, but now won’t start at all. Where should I post to get help for it? Can provide more details.

 

start a thread in the tech forum in title list your bike initial issues. in the opening post tell us what bike what you have done to it or if it is a new to you bike. my first guess to your issue would be low battery put a meter on battery 12.8 volts is what you are looking for. press starter button motor spins what does voltage drop to? under 10 volts it will spin but not start. got a charger charge the battery no more than a 2 amp charger..
if lead acid battery look at acid level if low replace missing fluid with distilled water.

 

I decided to buy a Turbo Seca and couldn't for the life of me figure out how to get the carburetors off. Googled "xj650 carburetors" and found this site.

 

I actualy am brand new at yamaha bikes.. an old starter.. a google search for yamaha forums brought me here. just started a new yamaha bike build out of what was left of an old 82. xj400.

 

Hello, I looked for information about it. I got here through the link on the page xjcd
About the machine, say that it is the liquid XJ 750X Maxim of the year 1986.bought in switzerland. This machine was not manufactured or sold in Spain. As far as I know, it is the second in my country.

 

I suspect the 750-X was a Canadian only bike.
Although quite common here in Canada, they would be very limited numbers in total.
Your example is in nice condition.

 

You're right. This is 738 number.
As for the condition, it was not like that when I bought it. One person was its sole owner and did not take very good care of it.

 

Google search for "XJ Forum"
Despite the rise of social groups/clubs, the best info will always be found on a forum.

 

Hello, I disassemble the clutch housing to see the state of the discs and I find these two pieces with this kind of mayonnaise. This is not normal, it looks like an oil to water emulsion. however I checked the condition of the engine oil and coolant and everything is fine. Does anyone know the function of these two kinds of bells?

 

looks like part 31 32 and 33

Interesting. But I don't understand the function of these parts

 

The 2 screws hold on the outer plate - maybe the PO of your bike thought they needed to seal them with something?

 

Google brought me here.
Was looking through craigslist/FB marketplace for a project bike and kept stumbling across the bike i have now... had been wanting a UJM again (had a CB125 for a hot second, but i live in a tiny town, so it didn't see any use) and after i saw how much information was in here, decided to pull the trigger.

Yep, was just saying the weird stuff on the outside, no idea what it's for other then someone might have been worried about leaks maybe?

 

Resolved. The function of these isolated plates of the crankcase cover is to trap the possible humidity that circulates inside the clutch. They are designed for cold and humid climates, especially on short trips when the engine cannot reach its full working temperature to eliminate this humidity

 

Google. My local bike shop no longer services Yamaha (f0cusing on Harleys I guess) so I had to brave the interwebs.

 

Googled, looking for data on the XJ900 Seca wheels. Found this forum and decided to join since the topic I stumbled upon relates well to my own ideas on how to make old bikes work/handle better.

 

You both found the right place

 

Found my way to this god send of a forum after I fell into the "partially running cheap yamaha" which is my 82 XJ 650 Maxim yics. Below is how I got it vs what I am looking to achieve, perhaps far fetched
