I only say this because I’ve just fitted one to one of my projects and it looks spot on and in proportion... just saying ...🤔

Tobyjugs, what a truly fantastic build this is! Amazing, that tank looks beautiful as does the rest of the bike, the choice of wheels too, perfect!
Keep the pics coming

I am very interested how Nico will set the geometry.
Will he need Kees on the bike to set it up? How does he work with sag? Does he an precalculation on the spring rates? Did he precalculated the centre of gravity? Or is it pure experience?
An interview video would be awesome! OK ok i am over ethousiast🤪

The geometry is i guess more or less set it's more a question of what goes up or down in height. The rear sets are still low compared to a real TZ racer. This is a good thing as my knees have started to play up since the build has begun.
When i was at PS tuning getting the pipes made i made a remark to Gerard (owner of the 500) and Pieter (PS Tuning) about how sharp the back of the tank was. They laughed a bit and said that there was nothing wrong with the tank. They advised me to strap a pillow to my belly and sleep on my front for a few months. Cheeky buggers!

the wheel center to crank relationship and general geometry looks the same ,near as ,as my 350 mito if so it will handle superbly I reckon especially with the quality suspension on yours theres probably more geometery adjustment in too  mike |

He has ridden in GP's so i tend to listen to him. He did question why i went to Nico Bakker instead of getting a Mito. I told him it has always been a dream to own a Bakker bike. |

The next component fitted was the radiator. Again using aTZ250 bike as a general reference for the size of components i decided to use a Kawasaki radiator. First the search was on for a secondhand one but the Alibaba prices are so cheap this seems to be the better option. An old contaminated radiator will be more difficult to weld compared to a new radiator. This radiator is used in the 400, 600 and 750 model. It fits nicely in a TZ 250 fairing but is too long (  ). It would have been very trick to see the whole radiator mounted.  The radiator was cut to the appropriate length which was as long as possible without hitting the exhaust pipes and blanked off.  Since the pipes have been mounted it looks like it might be possible to mount the complete radiator if it is slightly tipped forward (that would be cool). Like the wheels on this build it is very difficult to make everything perfect the first time around. I guess this is what a special build is all about. I can totally understand Veg being frustrated about all the niggly fitting problems. This is one of the reason some Cheap Charly parts have been used. These will be replaced with proper parts once everything is up and running to my satisfaction. |

The next thing made was the exhaust pipes. Here are some pictures of the pipes being built.  First both the front cones were made  Then the right hand pipe was fabricated.  Then the left side.  Here is a more detailed picture of the workmanship.  The pipes were almost finished and the builder was waiting for my final approval before he finished them.  After some final adjustments the pipes are ready for the silencers. The end of the pipes do look a bit wiggly woggly but when the silencers are mounted it all looks straight and in line.    One last detailed picture with the names of the people who have done most of the work. Bakker Framebouw and PS Tuning  PS Tuning can only supply aluminium silencers for this size pipe. I have been trying to find a supplier of carbon /Kevlar tubing so i can make some silencers. At i have still not found a source. |

That chassis looks so light. It reminds me of a tropical wasp waiting to pounce on it's next victim |

its odd how pictures are sometimes not loaded , I can't see mine here on my works pc my avtar is also not loading
but I can see all your pics
looks lovely btw , especially like the footrest/pipe/rear brake/swinging arm detail

Wow! Absolutely amazing Toby some fine engineering here.
When finished, it will be one of those bikes that will have people looking in silence, admiring all the little trick bits over the entire thing and nodding in appreciation.
You must be well pleased with progress so far
Keep up the great work (and the updates)
John

You could try this place > www.pjengineering.co.uk/Hi Chippy thanks for the link. I only see carbon tubing, i want Carbon/Kevlar weave which has to be around the 60 mm diameter. If not it will be good old aluminium. |

Today out of curiosity i weighed the weight of a 39 tooth sprocket from the Marchesini rim and the 3XV rim.
The 3XV sprocket weighed 607 grams compared to 243 grams from the 5KE rim. The rear disc on the 3XV weighed 825 grams compared to 265 grams for the 5KE rear disc.
This means i have saved 924 grams (almost a kilo) from two relatively small components

Sounds interesting,
Christ here we go again.
Back story , I like retro mountain bikes , I have several (80 odd) of the bloody things , one aspect of this nonsense is weight weenieism
We used to have build offs , weight weenie build offs , to build a fully functioning bike that will be used at a forum rideout
I built a 18lb gt zaskar one year , lots of cnc modding of stuff and selecting the lightest stuff , my mate kaiser built a 16 ld cannondale , ffs back to the drawing board

This project is a bit slow moving at the moment, but I've squashed me apples and the juice is bubbling away nicely and the other two bike i had odd jobs on are also finished. So hopefully i will now be able to start with building the gearbox up and work out some gear ratios. It could be a bit of a mix and match between YPVS and Banshee. I won't know until i start playing with it all. In the mean time i have made a throttle cable using a Domino Twin Pull throttle. I have fixed small washers to the outer cable end so that i can lock it with wire to fix to the other side to keep it tightly in place.  After i made the cables i realised that i cannot easily release the throttle cable at the twist grip end very easily because the bends are threaded into the housing. Ive asked a well known spare parts vendor from this forum if he has any crappy YPVS cables i can butcher the parts off to make some better throttle housing fittings. I am now thinking about boring out the thread in the twist grip housing so the spigot end from the bend can be pushed into place and then held in with locking wire. If anyone has some suggestions or better ideas i'm all ears. |

If you set the cable adjusters more at the maximum length, you could just slack them off to give you enough play to get the cables out the throttle tube. Because you have them set at the shortest setting, you cannot free up any slack :-(

This means i have to screw the bends loose, which is not very handy  |
