1994 VFR750FR rebuild ..... warning, it isn't going back to stock!

Hi All,
I bought this bike back in September 2013 from a guy that had hit a cow whilst out riding.



The wiring was butchered, but it ran and had a gear box, brakes etc (yes I did test ride it around the town like this) so a deal was done and I dragged it home.



First thing was to get it pulled down and find out what was what.

Seat unit was removed


Front end came off


and there wasn't much left


New bits were soon on the way

 

New Suzuki GSXR 1000 K7 bits arrived


Assembled into one big bit


And bolted on the bike


Back on both wheels


Yamaha R1 rear sets fitted


Top triple tree drilled and Renthal bar risers fitted


Start mocking up the new rear sub frame and seat unit




Suzuki RM250 fat bars fitted

 

Exhausts before


during......


and after.......


And fitted to the bike

 

Headlight trial fitted


New clocks arrived


So it was time to pull it all apart and head off to the painters

 

Frame and swing arm painted




It was easier to lift the frame over the engine so the build literally started from the ground up.




As soon as the bottom triple tree was on I could get the front paddock stand in place and build up the front forks. I also got the rear subframe fitted.


Wheels and tires fitted




Most of the wiring was done during the dry build so this was a cake walk


Time for the body work





And that was that



or so I thought
The dreaded VFR electrical gremlins came out to play




A new Stator was purchased and fitted along with a new reg/rec unit.


Despite my best efforts my battery looked like this at the end of a ride one day


So another new reg/rec was ordered and fitted along with a new battery.
I went for the Shindengen Mosfet FH020AA reg/rec and I'm very happy to say there have been no further issues to date.

 

Since "finishing" the build I have raised the rear sub frame 50mm as the rear tire was touching the exhausts on full compression 2 up.
I also relocated the number plate and spaced the rear shock 7mm so quicken the steering.


The body lines flow very nicely from tank to seat unit. I just need to make some fill in panels to go between the tank and frame and that should be it all done.
New wave rotors were also fitted as the originals were getting near the service limit.

 

Not really a fan of naked VFR's but you have done a great job, cool overflow bottle! Wish we could use number plates like that in SA. Did the GSXR front end bolt straight on and is there much change in the front ride height?

 

not a big fan of naked/street fighter but she is a beauty and you have done some very nice work cant wait to see it finished and painted!!

 

The bike looks good!! Great job with the build!!

Thanks for the comments.
I'm not a huge fan of naked bikes, but with the speed limit being 100kmh (62mph) and heavily enforced there is little point having a fast bike here in NZ.
This will easily cruise at 130-140kmh with zero fairing to hide behind and that's fast enough to get it impounded if caught.
Also the cost of 2nd hand parts in NZ far exceed the value of the bike so it was way cheaper to go this route with the bike.

The GSXR forks are approx 30mm shorter than the VFR's. so you loose a fair bit of steering geometry and it becomes lazy thru the bends, that's why I jacked the rear up to compensate.

The VFR shares the same bottom bearing as the GSXR, and the top bearing (30x47x15) is an off the shelf item from evolutionsuspension.com They actually supply a 30x47x9 with a 6mm spacer and dust seal.The GSXR front is a direct bolt in with new taper bearings.

 

Nice job and a great write up. She looks pretty sweet.

 

damn. That seemed very easy. Where did you learn about the front end ? I think I may over looked it but what is that tail off and how hard was the exhaust?

 

That looks great! and like erbilabuc said, you made it look too easy.

One big question: what did you do with your oil cooler?

 

Hey all.

Front end was researched on a Suzuki SV forum, and several street fighter forums. If you spend a bit of time and dig around you can find lists of bearing sizes, spindle sizes, who makes what fit into where etc. Then it is just a case of selecting the parts you want and fitting them together.
The tail unit, seats and sub frame are all Ducati 1098, and so is the exhaust, with a custom built link pipe to the stock VFR system.
I removed the cats and baffles from the stock Ducati end cans and replaced them with 2.5" perforated pipe and muffler wrap. They sounds great now
The oil cooler was removed and a bypass hose made. Temperatures here in NZ never really get above 30C even in summer so no real need for a cooler. Also, with all the fairings removed the engine is getting plenty of cool air flowing over it. I do have an oil temp to fit, but not done so yet.

 

NZ that makes seance beautiful country i want to visit there some day. the police that bad there? thats unfortunate dont get it impounded i want to see it finished

 

Driving training and road conditions don't factor in to accidents, so the police blame everything on speed.
Current tolerance is 10kmh over the limit and you get booked, but for the last 2 months they have dropped the tolerance to 5kmh over the limit and are considering it a permanent change.
Speed camera vans are completely unmarked and are parked behind road furniture/trees etc in order to hide from view. They are not deployed in high accident/incident areas but in areas where they will catch speeding.
Its a joke but you get used to it.

 

That bike is gorgeous! I love the paint scheme... Well done!

Beautifully done yeah... you made it look easy...

 

Did the R1 rearsets raise the pegs at all? I drag my foot more than i'd like.

The rear sets are fully adjustable into 1 of 9 different positions so could sort this problem.
