I actually got in touch with a guy with a vf1000 engine, I fancy it then the bike may live up to its reputation.

What have you done on the engine so far? I would be inclined to sort the engine you got, it won't cost anything to see if it runs.

btw your pics aren't working.
Nothing yet. I got the motor out and on the ground the other night but haven't got to crack it open yet. Need to dive into that one night this week or this weekend and see what lies beneath.

I'll see what's up with the Photobucket stuff. They seem to be working when I look at them, but that doesn't mean anything I guess.

Just checked it out, looks like you can't move what folder they're in on Photobucket and expect them to stay linked... Learned something today.

Before you took it out did you try and turn it over with the clutch held in? Might be a box problem that's stopping it turning over.

You put anything down the plug holes yet?

No as the clutch wasn't functioning. It appears to have leaked all over that side case and had no fluid left in it.

I've got Marvel Mystery Oil and some PB Blaster down the plug holes and have since the first day. Hasn't broken free yet when I tried last night as I was walking by it.

yeah thats common, a few sources of leaks there, the crush washers, the slave corroding under the crush washer, the hose or an internal leak.

heads are easy to pull though which is nice. But I reckon with enough time it will free off.

Cool thread. I'm working over a VF1000R of similar vintage. My clutch wasn't operating when I got my bike either, but a master/slave rebuild kit took care of that. I got it from this place: http://www.v4market.com/Interceptor_c_9.html

If you ever wind up picking up a parts bike and somehow wind up with an extra VF700/750 tank that isn't beat up/rusted, let me know, I might be interested.

Also, contact Jamie Daugherty at Daugherty Motor Sports, he's good people and digs honda V4's. VFRworld.com is also a good place to go for advice and encouragement.

Heads are off and it aint pretty. Not looking promising, kids.

Thats a lot of rust. Pistons are seized in there right now. Valves are not looking too pretty either.

Thoughts? Time to find another motor or what? Front cylinder cam chain was even rusted in place and has several links that don't want to move. Its at least going to have to be replaced.

Tearing heads off of one that's seized is a bit of a pain. You can't line up the cams enough to get the bolts in position. Of course, they were at top and bottom and took and end wrench with little 1/8th turns the whole way.

Yikes! Hard to imagine it would be practical to save it the way it looks?
I think a $3-400 used motor would be the way to go.

pfft, you'll get that sorted tea time tomorrow sunshine!

The heads give them a good scrub down, jetwash them and scrub em.

Then check to see if the valves move.

the pistons, tbh give them a blast to and drain the sump. then if you can some dry ice on the pistons might be enough to get them shifting a bit.

Otherwise time, patience and oil, acetone/atf mix etc.

Or the other old trick is split the cases, put the heads back on, remove the crank and grease nipple onto an old spark plug and force them out that way.

I would get that engine going before wasting money on another that will undoubtedly need work anyway

I think you're more confident in my ability to resurrect this than I am! I think this one is a lost cause. I'll have more money in just recutting and lapping 16 valves than I will in finding a donor motor.

There's an '83 VF750 engine on eBay right now from a salvage place in Ohio with good feedback that supposedly came from a good running bike and has good compression on all 4 cylinders for $350. I think that is going to be the way to go here. Now I need to see what shipping costs are going to be on that 200 lbs beast!

350 over here would buy you 2 runners.

It doesn't have to be perfect to be running. get it running then if its a total bag of bolts new engine.

Otherwise get it running see what its like enjoy it for a cheap bike then maybe do a nut and bolt resto on it later if you so wish. This way you keep the original engine No etc

Coming apart

Started getting the bike apart tonight getting it ready for powdercoating. Frame, wheels, trees, etc all going in for sandblasting and powder in the next few weeks.

what colour?

bright pink I reckon

The euro bikes never have the year of manufacture tag on them, its annoying.

In fact all 3 of mine none have anything aside from the stamp at the headstock.

Did you find a used engine?
I'm currently trying to get my 2 83's running and I'm finding my share of issues. The nicer of the two is running, but it sounds like the rear cam chain tensioner is shot so I'm waiting on a new one of those.

I realized my shock on the nice one was sacked, so I swapped in the other's.
I bounced on it a few times and thought.. hmm.. feels pretty good. It then promptly puked all its oil over the floor. LOL.. Old shit is fun to work on but sometimes it is trying.

Just back to a metallic silver for the frame and swingarm and gloss black for the wheels, trees, bars, etc.

I have located a good engine, finances have kept me from purchasing it just yet, but hopefully its still around after I pay Uncle Sam. Kind of doing the "free tinkering" right now until I get cash in hand.
