5th gen maintenance --6th gen and other parts that work on 5th gens

[mello dude]

New thread but is probably useful. Since the 5th gen bikes are 24 to 27 years old, more and more parts are getting listed as not available in the parts fisches.

But many parts still listed for the 6th also are the same or very simular to the 5ths and will work fine. 

 

Recent example... This rear brake guide snapped off and the new 6th is near identical.. 

5th vs 6th

 

 

 

Anyway I think Terry confirmed that 6th gen insulators will work on 5th gens...

 

Would like to continue building this thread. If you could plz.... List your 6th parts you have used lately or have found for a fact that they also work on 5th gens. Lets see how far we can go with this. 

 

Thanks all and cheerz

What mellow said.

[Terry]

Wheels, front axle and discs are all the same.

FWIW, any 6th-gen part with "MBG" in its part number is a 5th-gen part already.

Thanks! Mine broke and I Macgyvered something up but will order up the 6G part.

Macgyvering is fine; the guide has two functions, holding the brake hose in place, but the second function is to act as a washer for the eccentric clamp bolt; if the washer is not present in some form, the bolt bottoms out without really clamping well, and chain tension will change on its own...

Stator and flywheel conversion?

Quicker reving?

[Ughandi]

You gotta turn yours on a lathe. Shaved nearly 2lbs off my 5th gen fly.

Quicker revving for sure. Engine response on rev-matching has not felt more instinctual.

This discussion is very interesting. Maybe there are also parts from the fourth generation that fit on the fifth?
The broken ring could have been repaired with a little welding, or at least that's what I would have done.

[mello dude]

^^^^If I was a DIY welder guy, yeah, I would have definately gone that route... 

For me, a new part was $8.xx.. good enuff... 

 

A very good thought about waht parts from other generations fit 5th and maybe others. 

[MBrane]

The Gen-Mar bar risers on my work 5th gen came from the 4th gen I had. Same fork diameter. I just had to round off the heads on the locator bolts so they would sit flat.

not a 6th gen part, but the fuel injectors share a part number with those from the '99-'01 CR-V. gave me a good chuckle when i found that out.

[mello dude]

I'm really liking this thread...may as well keep this going... what different parts will fit on what bike.....

On that note. If you manage to lose the lug nuts that hold your rear rim  onto the Swingarm, your CRV lugnuts you use when you swap out summer tires for snow tires are the same. Part number is different because of the finish, but got me by for a summer about 4 years ago until I finally found my VFR's under my lift.😁

Not a sixth gen, but I stumbled across some shared parts with the VTX1800.  The slave cylinder for the monster twin and the fifth gen appear to be the same other than a coat of black paint and price difference (VFR one is pricier).  The slave on my 1800 started weeping, and I was all set for a soft parts rebuild but there's some hard crud in the piston bore that needs delicate removal.  The 1800 slave cylinder looked really familiar, and I remembered I have a stock of VFR critical spares and pulled a new slave assembly and piston off the shelf.  Everything looked identical down to the casting and bolt pattern so I threw it on the VTX where it's been for the last 30K miles.  This means when I get off my duff and toss the VTX assembly in a parts cleaner and replace the soft bits it'll go on a shelf.  If I need it for the VFR I'll grab a can of Rustoleum black enamel and give it a coat.  If you look at the price difference between the two that's one expensive Honda paint job for the black finish.  No concern for the black cylinder installed on the VTX cause all that crap is covered by decorative chrome side cover.

Good info! 

[MBrane]

I suspect with some strategic digging you could find many more parts common to Hondas in general. Why reinvent the wheel? The Japanese are pretty crafty that way.

[Terry]

 

Partzilla's website allows you to look up parts and then see which other models they fit. The complete clutch slave is common to the CBR1100XX, VTR1000F, RC51. The slave piston is common to 1500 Goldwings from 89, ST1100. The water pump is shared with the CBR900RR.

 

I found out (in desperation) that the throttle tube is the same piece on my 99 VFR800 and my '15 VFR1200, but the parts manuals don't show that due to the difference in grip design that can be model specific. Paint colours cause the same apparent incompatibility.

[mello dude]

Typical Honda, a core set of parts go across a hundred bikes....

Yeah, I knew of the "all models using this part" list but that only works with identical part numbers.  Like the slave cylinder compatibility, the number of similar to identical parts with different numbers out there is unknown.

 

Another I do know is the shifter shaft oil seal.  Different numbers for the VTX and VFR, but it's the same size seal for both.

[JZH]

Another trick to find compatible parts with different part numbers is to seek out a few aftermarket catalogs, e.g., for master cylinders I would check the K&L catalog and see which of their rebuild kits cross-ref with which bikes.  It's not 100% reliable, but it sometimes works!
