I bought a matching pair (serial numbers are 12 apart) of 83 VF750Fs a month or so ago. Both are in excellent shape, but neither run but apparently did 3 years ago. Both have very very low miles. Tanks and carbs are varnished up but have no other known issues. I'll be tackling them soon!

What products do you like for cleaning up the crabs? I've been using Yamaha Carb Dip, but I'm open to suggestions!

LOLOL!

That's what I get for the fast typing.

Hank.SD · 02-22-2011, 06:46 AM

Well I was planning on cleaning the crabs

with a big ol' pinesol bath as suggested here. A carb dip, gumout and compressed air is all I've ever used before.

I have a friend who's had good luck removing all rubber and plastic bits and boiling the bodies in distilled water too. I guess that would be my last resort though!

DesmoTull · 02-22-2011, 07:33 AM

I'll have to look up the pinesol solution.

Thanks for the input!

Pinesol is good for REALLY nasty carbs, but you still need to clean them the manual way after that. HD, Yamaha and Suzuki all teach cleaning with strands of copper wires with the occasional spritz of carb cleaner to help soften the deposits and compressed air to blow the crumbs free.

Here's a set of carbs I recently soaked in pinesol, before and after:

Bike runs great now.

Personally (I have over 100k miles on both an 87 700 and an 86 750), I liked the 700 motor better.

Dead reliable engines for the most part, the charging system (as a whole) was the weak link. I had one rotor cook it's wires inside the cover (broken connection), several plugs roast themselves to death and went through 4 Reg/Rec units (lasted roughly 30k miles). The engines do run hot and I installed a manual fan switch to keep ahead of the curve when I know I'd be stopping for awhile in traffic. Past that, it's the normal old bike limitations, spares are hard to come by and expensive when you find them. The wheels are odd sized, forks are REALLY skinny and flex like crazy, shock will be trash at this point in life, etc... I love the bikes, hate that I sold mine (could only afford one bike and had modded mine into a street legal racer that wasn't fitting with my recently acquired live-in GF) and will buy one again sometime in the future... if I don't find an RC30 first.

I had an HRC exhaust, '94 F2 (cartridge) front end, F2 rear wheel, and put an 86 750 motor in the 87 700 chassis. Oh yeah, there was a fox shock out back and a corbin seat under my behind... I think I had some sort of rearsets on there too.

Isn't this pic taken near Highlands North Carolina?

Yup, was Bridal Veil Falls (of which there are a billion in the States) on 28... I think? It's been a decade.

I'd heard that they moved the blockades so you can now ride/drive up under the falls there now.

...and have decided to do a total "restoration" of the VF700. I considered parting it out, but I've wanted one of these bikes since I was a kid and I just can't bring myself to do it.

So, she's going under the knife and coming out a whole new girl. Down to a bare frame for sandblasting and powdercoating, overhaul of the motor, new paint, etc, etc.

I know, I'll never get my money back out of it, but this gives me a reason to keep it and never get rid of it. Just make it the start to the obsession and collection I've always wanted.

LuciferMutt · 02-22-2011, 05:30 PM

Cool! Thanks for bringing an old bike back to life.

chambersc · 02-22-2011, 07:12 PM

We had a little discussion tonight... I won.

Big Red One · 02-22-2011, 08:16 PM

Ahh... very nice!

I need to clean the carbs on my '84 VF700 and get her back on the road.

Speaking of that, I just got mine finished up after the 3 day Pine Sol treamtment and scrub down. Should have taken a before photo. They were NASTY.

chambersc · 02-24-2011, 09:52 AM

So I've stumbled across an 83 750 interceptor motor for a decent price. Willll they bolt in and everything work or were there differences between that and the 85 VF700 Interceptor?

OR, anybody got a good motor laying aound that might make life easier than resurrecting this seized one?

chammyman · 02-24-2011, 10:00 AM

the 700, 750 and 1000f are all the same, the 4/500 isn't.

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.
