ED,

He ( Mike at http://www.enginedynamics.com/) had a special bit or end mill made for his mill that is the same diameter as the center of the cam. He welds up the affected area and chucks the head in the mill and makes his cuts. The bit looks like a bull nose or round tip drill bit and he makes the cuts by moving the head sideways. He first registers the bit at the top edge of the head and then lowers the bit a specific ammount as the XR350 and XR600 heads have different spec from lip of head to the journal.

The cause for the center journal is two fold. One is of course running low on oil but the other is since there is a low or no oil level the head gets REALLY hot and the combustion chamber actually expands upwards putting pressure on the center journal. That and the low/no oil situation lead the journals demise.

Thanks, does anyone has a picture of the special tool used?

What we usually do over here, it's to install a bronze half bearing with a hofman pin to avoid rotation.

ok now the bronze sounds more like a "permanent" fix than just putting more aluminum in to get worn back out...got more details?

I have been looking for a 500 or 600 Honda fit over 6 months. My first priority is to ensure it has a title so I can register it to ride on the street. I have had no luck in the title department and most have been sold. The only one left is 2 hours from me. This is what the ad said. 1983 xl600r

This bike is not in mint condition, as a matter of fact the pictures show it looking better that it is,these are recent pictures too.currently the gas tank has been drained and will not start, complete with all original equipment, with title, great fixer upper or restore project, I bought this bike as a package deal, and dont have time to restore it now, engine condition unknown,but it does kick over, this bike takes more work than just put gas in it and start it. Price is FIRM $750

What do y'all think? Worth it? It has compression when nicked over and the trans goes in all the gears. Realistically if the engine needs rebuilt how much will I have to put in it at most for a stock rebuild?

getting a title is soooooooooooo much easier than most ppl realize

id be willing to bet if its got good compresion it probably just needs the carbs gone thru and it will fire....what i WOULD be worried about is makeing sure its got spark..cause if it doesnt that could be a few hundred fixing that..stator, cdi, coil, magnetic pickup

Parts are getting expensive. It all comes down to what you have to start with. Some have got it done from $1000 and some waaay over $3,000.

Not in WI. Only the currently registered owner can apply for a "replacement" title. If the bike has changed hands since then you're only option is to track down said registered owner and then get them to take a trip to the DMV.

Just because it has compression doesn't mean it's good. Low comp motors start like hell and love to stall. It's a bad combo for a kick start bike. Honda manual says 175psi of comp warm. My bike had about 90psi when I got it and was hardly ride able. For a rebuild have about $150 or so for a piston w/ ring set, about $100 for a gasket kit, $80 or $90 for a timing chain, and leave some room for a valve set $70 to $120 for Stainless. Machining should cost about $40 to $60 for a bore and probably about the same for a head job if needed.

If the bodywork, tank, and seat are in decent shape then $750 isn't bad, or if it's at least a stock unmolested bike. If it's beat up and hacked up then stay away. The second XL I bought was running, riding, and titled with a nice tank but trashed plastics and I got it for $500.

No, I paid $800 for a running 84 RFVC XR500 that was all original and in better shape than you describe for this 83 XL6. It came with a title too.

I think I paid too much and I have close to another $800 in my bike to get it the way I wanted. But it depends upon your market and how much work you want to do (and can do) on these old machines.

Lost air mixture screw

Hi Guys,

Does anyone know where I could find a replacement air/mixture screw? Or can I just take any screw that will fit it? I've never really looked at it (so don't know if there is anything special about it) and now it's gone. Bike runs, but idles rough and will not run well at constant speed. I checked the diagrams at bikebandit, but it does not seem listed there (the diagram ain't great, so I could have just missed it).

Thanks!

And no, you cannot use just any screw. It has a calibrated, tapered tip on it.
And it should have an o-ring on it to prevent it from backing out as I recall.
