KR1 Refurb.

Post by Garry » Mon Jan 28, 2019 2:34 pm

Not really a project - but have been transferring everything from my KR1 / KR1S hybrid on to a new frame (old one had damage) since just before the winter.

Sprayed the new one and polished the main frame spars.

Everything has been checked/cleaned/sprayed/lubed as required as i went along. Replaced most of the manky fasteners and put good
a lot of neglected jobs over the years.

Almost finished now and looking forwards to starting it up and refitting the body work.

First time out the shed today :P

often wondered, is how much stiffer the KR-1S frame is to a KR-1
second moment of area says about 9.4% stiffer
the 0.7mm thicker main spars will add estimated 400g to the KR-1S frame weight

on my old B I filled the frame rib depressions with black vinyl strip (kitchen draw vinyl)
also around swingarm pivot
saw someone do it once on the original old e-box ZX-10
quick and simple mod makes the KR-1 frame look more different and 3 polished ribs will really pop.
since you are going with black accent vs polish

...parked on a shelf next to the Ark :P

I got the vinyl at local hardware - resisted going for a wood veneer inlay look that was other choices on offer

Pity I couldn't find a 1S frame for my project- a 9% increase in stiffness is a worthwhile gain which more than compensates for the slight weight disadvantage.

Frame stiffness

Post by KR-1R » Tue Jan 29, 2019 11:29 pm

factory frame mods to other bikes: road to race trim (such as YZF750) included welding plates on key areas to stiffen.

the 9% stiffness KR-1S advantage could be eliminated between the two by doing either of following to a KR-1 frame...
1. glue a 80 x 1.2mm sheet along the inner face of each beam
OR
2. glue/weld a 20 x 2.5mm strip along the top edge of each beam section

I suggest glue/bonding because unknown what weakening affect welding could do to the frame over large area.

BUT I wouldn't bother - less weight is better. Nothing wrong with a KR-1

Danny,
I think some nice mahogany veneer in the KR1 frame troughs would solve the stiffness issue and be aesthetically very pleasing :lol:

Passed on the veneer suggestion

Had it running - just a leak one carb due to an oval fuel pipe clip, replaced it and seems okay now

A few fairing repairs to do then should be ready for MOT

Thanks

All back together now

Just need a shakedown run up the lane then get it MOT'd - with a pass hopefully :oops:
