Shirley there’s a reason many FI bikes have rubber mounted throttlebodies? Don’t think they do that on cars though. Maybe something to do with revs and vibration?

With radial calipers diameter shouldn’t be an issue? Might require the right calipers though. Have you looked at the famous ‘Sam’s forkchart’? You might get close to the 140mm with srad yokes and k3/6 thou forks. Forks should slot straight in and would increase width by 7mm.

Cheers for that, the idea came from here and glad I have gone that way.

Thanks for the insight gents, saves me a job.

Anyone used zx-10r forks and yokes on an 1100 slingshot? If so, are there any pitfalls? I am guessing they may be too short. I need a set of forks for next year's project and to fit a fancy wheel and discs I need Kawasaki fitment for 300mm discs spaced 140mm apart. A possible alternative is z1000sx 10-15, but I need to get to a bike dealers with a measuring tape to make sure. Later models have larger discs so won't work with my wheel/disc combo. Thanks for any constructive input

I think Nick Pepper at SPS supplies 'EFE-style' filter plates for non-efe gsx1100s.

So today I've mainly been driving Road trip to Centurion Motorcycle Projects HQ to drop the engine cases off for paint. Would you belive Brian had another very beautiful F1 in his workshop making a wiring loom for it

I use the boiling water/freezer method on bearings and it always works a treat. Bearing in a sealed bag with maybe a squirt of WD40, couple of hours in the freezer and boiling water over whatever it's going into.

As @Toecuttersays, they can be pressed/pulled in without issue, it's smacking them in that causes the damage. You can use clamps, a press, a length of threaded bar through the centres, a puller from the other side etc. Basically anything which applies an even pressure as that's what they're designed to take even when they're not rotating.

They're v expensive too as well as being tight and fiddly. On my Spondon it uses on each side two seperate bearings: a needle roller thrust bearing and a cage needle roller pressed into the swingarm. This seems a better thought out design than that used by Harris.

'Tis true, injectors hold miniscule ammounts of fuel and fuel in rail is continually recirculated (providing its not a deadheaded system!) Most injectors also have wiggle room in the injector 'cup' and are isolated via o-ring so not a lot of direct heat transfer.

The one in the picture is number 9 in the diagram..I’ve only had one mark 2 but it was the same as the diagram, don’t know what you have going down the right side, unless it’s the fuel tank filler water drain and comes from the tank not the air box

The engine breather pipe which connects to top of the airbox is in situ.

Hi there, this is one of the plugged pipes coming of the airbox, the other is on the other side which is a long pipe which is fed down to the bottom of the right side foot rest. That is also plugged too.

They are a bit of a bugger to get in. I used a sash clamp to press them in with a piece of material turned down to seat on the outer edge to protect the bearing. They are v tight and a bit fiddly. You could start them off square, carefully then press them in on a normal press. Just have to ensure everything nice and clear of powdercoat to allow them to pop in square. Good luck.

There should be one at the top from the engine breather and one at the bottom which like GSXR1460 said, is plugged to drain water, have you got a picture of said 2 plugged ones????

Dunno. It's possible I suppose. I am puzzled as to how they go in fully without the use of force, which will obviously potentially risk buggering up the thrust part of the bearing. https://simplybearings.co.uk/shop/p556652/NKX25Z-Budget-Needle-/-Ball-Thrust-Bearing-with-Closure-Ring/Cover-25x37x30mm/product_info.html

I still use the original cover, I just blanked the hole in the crankcase completely with a machined plug & o ring so 100% of oil runs through the cooler. Never been a problem in 15 years. I only use a 7 row cooler as anything larger overcooled (in the UK though)

TBH in hindsight i don't think heat soak will be a major issue unlike on carbs which have float bowls etc

I’ll be coming for the day - in the car!

if you want an EFE filter cover i should have one some ware

Very nice, if i would ever build a turbo bike again with space to go draw through i will pick your route draw through looks efi driven. Awesome!

Can’t you heat it with a freshly boiled kettle- done that before on wheel bearings that have been in the freezer department, slipped in a treat

Thanks, that's a big help. How did you fit the new bearings? I am guessing they have to be very carefully pressed in after cooling the bearings first in a freezer. I think that's how I did my last lot but I can't remember exactly. Obviously, the swingarm can't be heated as that will bugger up the paint.
