NP2650

I already bought the cam chain guide from Gary, but was asking about also replacing the tensioner.

Looks like I caught this situation just in time. The "plastic" part of the guide had come completely off the aluminum and was down in...

Yup, same bike. I just messaged the "owner" who claims to have owned it for 18 years. Scammer.

Some red flags to me too. However, he gave his phone # and I spoke with him yesterday. Reportedly he is in Van Buren, Maine. I asked...

Anyone familiar with this bike or the owner, a Dave Fabre in Maine? It's posted on Facebook's XS650 Society. I can't get a link to FB...

It's a 78, and yes it has the heavier one that sits below the cavity as you described. I've read the various threads on squeezing the...

While I'm waiting on parts to replace my cam chain guide, etc., I thought I'd tackle the starter gear issue. Does the grind/spin thing...

Thanks gentlemen. I assumed as much, but I was hoping that just maybe it might be less involved. With less than 10K on the bike, I...

Jim, can you elaborate on exactly what you are suggesting in terms of a "full top end refresh"?

Pulled my drain plug and oil strainer cover today to find the dreaded cam chain guide bits. When replacing the guide, does it also make...

Over the years, I have done some work at several nuclear power plants. As you can image, cooling system components are exposed to some...

Doing my bushings now and this thread has been a great help. One question I have is what is the best grease to use with these bushings?

I just did my tank which had some light rust from condensation. First, tried vinegar and that just didn't work. Then a splurged for 2...

I pulled the tank from my 78 XS650SE to clean and repaint it. At some point, someone replaced the original petcocks with the type...

The Cranbrook had the 218ci flathead 6, very similar to the 230ci. 218s were more common in cars and trucks got the 230. Mine still has...

Yes, 230ci flathead 6 with a whopping 76 hp!

Do vintage trucks count? Here's my 1949 Dodge Power Wagon.

Ouch. Too bad since it looks like an XS1. Not far from me, but not sure there is even much that's salvageable...

It's in the Yamaha XS650SE Supplementary Service Manual. The related XS650E service manual lists 10 wt oil.

Service manual indicates 20w fork oil, but reading older posts on this forum, looks like a few are recommending a lighter 10w oil...

I just drained the oil and pulled the front springs from my 78 special. The springs that were installed appear to be progressive springs...

Yes, depends on what you get a degree in. I was lucky in that I always knew I liked science. Got degrees in engineering geology, and had...

I'm a scientist/engineer myself, but aways thought the push for everyone to go to college was a mistake. Around here high schools are...

Looking to replace my stock (and tired) front fork springs. I found a set of Progression Suspension springs from 650 Central for $97 or...

The front shocks on my 1978 special have been modified into air shocks. I checked and there is only a couple of psi in there now. Is...
