Frankenbolt / Frankenstein bolt

Hey guys,

 

New here and from across the pond. I own a 2000 VFR800Fi, i am addicted to.

 

My question is regarding the funky bolts that honda decided to put on the VFR originally. I do not own them, my bike came with a flush screwset with a flatscrew driver head on the bolt. But last summer i had a bag strapped to the back for a road trip and the bag kept sliding around. conclusion: i need them frankenbolts. the question i have is i saw on this topic someone suggested using the slimmer 'chique' bolts from a cbr 900RR i believe 93-98. Does anyone have any experience with this? and if so what parts are needed? just #18 or #13 + #14 + #18

Or if you have any other alternatives id love to hear them. The only way i can order them results in them costing 30 euros a piece so 60 euros for a set. (VFR bolt) seems a bit over the top for a bolt

CMSNL still has some, but you have to search the model year. I have successfully used stainless shoulder bolts from McMaster Carr. I think they are M6. But the bolt isn't the biggie, it's the sleeve. I just ordered 10 of them from CMSNL at 8.96 euros each.

If you have limited economic possibilities you can try these, from Praxis:

You get 5 bolts for €1.89. So that would be, you know, cheaper. They fit fine and have the shoulders you’re looking for but unfortunately they’re not stainless.

I feel like someone just ordered the frankebolts for their 5g in a recent thread... have you searched?  I'm sure someone posted about them still being available sometime in the past month or so

(i bought a 5g in August so i've been tuned in a little more to those threads than just 6g)

These are cool, But the require you to drill out the thread of the subframe. I have looked at them before when i still had the seat cowl on. That is something i really do not want to do. I like keeping most things OEM and all the mods reversible if possible. Thats why im not drilling holes in my fairing for a USB socket, but mounting the HISS plate holder.

What do you mean with the sleeve? I do not have a sleeve on my bike currently. So definitely missing that as well 👀

 

 

Its not that i cannot afford the bolts btw. It just seems a bit excessive to pay 30 euros per bolt. And i would like to know if the CBR bolts are worth it. cuz they dont stick out as far and apparently the finish is better on them. Still hoping someone has bought em 😄

That was me. See my post from May 2 on this thread. Pics and part numbers included.

The CBR900 parts you post are above are the same Honda part used on the RC51, which I recently purchased for an RC51 tail swap I am doing on my 5th Gen. In $CAD the retail price from Honda was Bolt $12, Spacer $5, Sleeve $6, so $46 for the full set or approx 30 Euros.

Honda Part #'s;

BOLT, SIDE COWL SETTING, 90116-KY2-700

COLLAR, SIDE COWL SETTING, 83642-KY2-700

SPACER, SIDE COWL SETTING, 83641-KY2-700

I read that. Wonderful read. And amazing work you put in to restore that baby. She looking real good! Fantastic work. As stated before the original frankenbolts i can definitely still get so thats not a worry.

 

 

 

@Dangeruss Did you swap the subframe too or just the cowls?

So for the original 5th gen cowl and subframe i need all 3 items you posted? bolt + spacer + sleeve?

The 'Blade (originally used on early CBR400RR NC23) rear cowl bolts are available in delicious titanium...

Yes, the RC51 bolts are meant to install with the bolt, collar and spacer. I think the intent of the plastic spacer is to move the 'hook' of whatever you attach to it away from the paint. and the sleeve gives it something solid to tighten on. No reason you couldn't just use the bolt alone, but it doesn't have the extra shoulder to locate the panel like the original  VFR bolts. The sleeve serves that purpose.

For the RC51 tail I modified the aluminum RC51 subframe to fit the VFR.

Here they are side by side, 5th gen part on the right. The 'shoulder' on the RC51 part is the sleeve that goes through the spacer to stop you from crushing it and the panel. The bare bolt looks like the one JZH posted above.
