Several hours of the day later, and achy wrists from all from all the cross slide twirling !  20mm hole drilled/bored down the middle   Bit of tinkering, fits the frame perfect ! will weld the two pieces if it works Scribed, centre punched & pilots already through  T'naaah it fits !   |

Nice machining job there mate.
Dont get me wrong, but have you ever thought that this ally link might fail under load??

Yes Kostas, well aware of load & potential consequence , if I get a reasonable static feel to this set up I'll get the two parts welded together, may source some more metal to construct one as suggested in previously posted picture ?

Had another look at this, GSXR linkage looks to be of similar dimensions to an RGV linkage. Quite different to the GK75...  The GSXR linkage was too wide for shock bottom fork, 32mm to a 30mm fork. The mount to frame & dogbone matched perfectly. I'd previously removed the needle roller bearing from the GSXR link, this is 30mm wide & fits shock eye comfortably. The centre bearing/spacer needs narrowing by 2mm but is hardened steel. Lathe cutting tools won't touch the hardened steel, if only for a grinding machine ! Bodging head back on , a lathe & an angle grinder = job done   30 mm spacer sorted, took a smidge off the width of linkage too - linisher pad for angle grinder and draw file flat.   Refitted original roller bearing, a 3rd adaptation of the bearing driver !  Tried several dogbone lengths, these are the longest |

Hard to judge angle of swing arm from this side, looks to have suspension travel like a motocrosser !     Need to keep myself motivated with pic's of tank/seat on   It sags by about 25mm with my weight on the back frame rails, from looking at RGV pic's, the swing arm angle doesn't look too far off ? First time I've tried owt like this, please let me know your opinions on linkage angle etc ? Cheers Matt |

Cheers Mike, look forward to an update on your build - that is looking good so far, don't doubt it'll be a stunner !

Wow, nearly 2 years down the line ! How time flies etc. Been back on with this for past while, on and off, built a motor for it, sourced some more bits... Nearly almost finished dry build  |

nice build .I had similar issues with rear suspension linkage I was using a 3ma swing arm. my solution was less elegant but worked .at some time when I have got the other jobs I am sorting on it out of the way I will have another look at it .the rear shock needs to be rebuilt or a new one fitted /after market. also I like the look with the rgv tank .

I'm using a Projection Components R6 shock lengthening adapter with some further mod's, bit sturdier than my Mk1 design |

Looking really good mate, come on a lot since I last saw it! Not sure about the lowering piece for the linkage though, I reckon any forces will be trying to pull it backwards which isn't so good? This will also put a tearing force on the original mounts. Could be wrong though, only what I am seeing as I try and imagine its movement. Can't see an easy way round it though apart from a complete new mount bolted though from underneath the frame cross piece locating on the triangular cutouts?

Great to see this up and nearly running! As per previous post - am liking the RGV tank on this frame, aided by the seat unit it's the best interpretation of a Mk 3 I've seen.. sorry Rich! In those colours, that headlamp smacks of a fairing-less Slabside GSXR and needs twinning . 'Blood Runners' anyone?! |

In those colours, that headlamp smacks of a fairing-less Slabside GSXR and needs twinning . 'Blood Runners' anyone?! It is half a slabside headlamp ! took the hacksaw to it, jack sh1t for sure It's gonna get a front number board with the offset headlamp, I'm using stuff I've already got on the whole, the small bates style lamps I've seen are lame looking in my opinion, deco only wanted single lamp & can't afford owt proper at the moment... Rich, yes further under bracing is in the plan for the drop link. Under the triangulated section bolting up to the front (2 m6 holes already there, tight fit to frame/link) should put little loading on the m6 fixings) - back to bishop & actress ! |

Can't see an easy way round it though apart from a complete new mount bolted though from underneath the frame cross piece locating on the triangular cutouts? Your reckoning was correct Rich, I've added an 'anti tramp' plate, nowt to do with vagrants lol... Combination of four M5 & two M6 fixings, if it does fail it's not gonna dump me on the floor, just loose a bit of ride height - the main drop link bottoms on frame without the plate attached.    It attaches to the frame using the mount on bottom frame cross section - visible in the first photo at top of page. I'm happy it ain't going nowhere, time will tell - my reasoning behind using M5 fixings , if it's gonna break I should think they'll be first to go ! ? ... Cheers Matt |

Sorry Matt, no hijack intended. Will put some pics on my build thread.
Impressive work BTW.

Superb build Matty
I can see from the work on the linkage you are a proper engineer, its brilliant.
There are so many unique idea from members on here attempting improbable/impossible engineering challenges - long may it continue.
The talents of the great British engineer for innovations is still outstanding.

Cheers mateys Steelaway, I did half an MOD mechanical engineering apprenticeship many years ago. There are some fantastically talented people out there, but I don't count myself as one of them, just a good bodger lol @ Botty - that's looking good, lovely welding. No worries re hijack |

Fired the Yamagamma up last sunday Pretty much finished as a dry build, run it up to temperature a couple of times - all seems well. Very rich though, I put 42 pilots & 155 mains in after reading countless PWK threads, but need to come down on both I think, starts without choke... Anyhow, here's some pic's ...  |

, however the GK75 linkage squeezes in there
