having really bad luck with my vf750f

hey guys
so i finaly found a crank and rods for my 83 interceptor that i bought off of pops on this site and when the pakage arrived there was a nice little letter from canada post saying they lost some of the contents of the package and the crank was missing from the box.......ive called them a few times and they basicly told me theres no chance of it ever turning up...its a shame becasue pops gave me a great deal on it and the rods to match it too .so now i am on the hunt for another crank and when i look on ebay i see lots of them that say :
VF750 VF 750 MAGNA SABRE INTERCEPTOR CRANK CRANKSHAFT

now my question is to you guys will this crank actually fit my 83 vf750f interceptor ???? are the magna and sabre cranks interchangeable with the interceptor and also do i have to find one specifically from an 83 interceptor???? or do will other year cranks fit my engine
thanks for any knowledge you guys provide for me

 

Sucks you are looking for 750 as I have a 700 set up you can have.

 

Well that sucks. If I was in this position I would look for a crank and rods from a 1000F/V65. Gives you a little more stroke and more tq, besides more cc's. I believe all the cranks are inter changeable. May be Dutchy will chime in and verify. He hangs out at Honda Sabre, Magna, Interceptor BBS - Index a lot. Check there. He has done a lot of engine mods and should know for sure.

 

I think I've read that the firing order/ rotation of the engine on the interceptor is reverse of what it is on the magna/sabre. I don't know enough to know whether you could make it work with a sabre or magna crank and how easy it would be. as for the 700, it has a shorter stroke, so I don't think you would want to use a crank from that engine

 

Yes Magnas and Sabers run opposite of the VF motors. The crank doesn't have anything to do with that. I'll look in to it this week to make 100% sure.

Just looked up the part numbers. 83 vf750f. vf750s are the same crank same part number 13300-mbo-020 and 030 are original. New replacement crank 13300-mbo-040. All the 360* cranks are inter changeable as far as I know. If you use a 1000 crank you need the rods as they are longer. Piston pin is same height on all 83-85 V motors.

Hell if you have to rebuild and get a crank. Mise well hot rod it a little. Same price.

 

"Hell if you have to rebuild and get a crank. Mise well hot rod it a little. Same price."

Or just find a VFR, something with more potential and fewer problems. Divorce is common, and YOU NEED TO REMEMBER you're not married to any old VF that won't go with the push of the starter button and has further potential problems even after you "rebuild" it.

How much are decent '86/'87s going for ?? Probably about the same amount you'd pay for a comprehensive rebuild of a VF......if you could find the parts !

 

Why do you want to find a second gen over a first? The 2nd gen is kind of inferior to the first as far as handling and braking. They have smaller fork tubes, no fork brace and ball bearing steering head instead of roller bearing. It has 40sq" less front brake area and 25 rear, front tire is narrower. So those characteristics that you need for a decent street bike are not there in stock form.

The motor is a little better hp but it's 180 crank vs 360. I think it's a few pounds lighter though it doesn't run the corners as well as a Gen1. Both bikes are old and hard to get some parts for. Though if you have a good gen 1 with good cams you don't need shit like the oil mod or have to worry about them as long as you use good MC oil and adjust the lash at .006 instead of .005.

At least mine is a strong running stocker. It has a Fox rear shock,has been rejetted and better brake pads that's it. I've run with 5th and 6th gens in the mountains of GA and they couldn't run away from me. Except on top end once we hit some good straights.

So if you can get the parts like crank,rods with good bearings you can have a good running motor. Though rebuilding any old bike is going to cost more than what it's worth. Money wise that is. Enjoyment may be something else. If your not wanting to throw that much in to rebuild then get a good 3rd-5th gen and you'll still may have to change some things on those if the prior OP hasn't. You have better parts availability with those compared to 1/2 gens.

 

Let's get scientific, Greybeard.

Run for pinks, you and me, meet up 1/2 way, Erie, PA, July 4th weekend, I'll bring my 700 #343 to run against your gen 1, OK ????? And i'll buy drinks after. What say, old man ?? Or are you Colonal Sanders ?:hss:otstir:

 

Anytime squirrelman I'll meet you at Nelson Ledges at the time of your choice. Let me know and bring the pink.
