Ive done same later gsxr k series switches great upgrade.

Bingo, now have spares too.

Brute force is right, Just use tiny drill bit or tiny tack or nail tip to tap float. Hinge pin out, be gentle mind you as the hinge posts can break if your too hammer happy,

Just fit new float needle valves in and this will fix flooding issues, only need untrasonc cleaning if there is idle issues, I can happily say I've used the German made profi fuel max . Additive in tank it's amazing stuff and ONLY one I'd would recommend . Cleans jets float bowls inside like new £15 per bottle lasts ages . M&p in uk sell it and sure you can find it in Europe too.

Defo Mikuni ,34,s are good carbs , those mikuni jet spacers are very important to hold the emulsion tubes Down, hence your lean issues and hotness problem ! You can just make them from alloy tube really there just a spacer .

Ive got one of these to do next week 98-gsxf rotten exhaust , I've got nexus pipe, from slabside which im sure with a little swapping of said sumps will be fine. It's just those horrid rotten head boots, plus gas and gas torch. Will see I guess , all good FUN ....

Ive just made one, you need bspt (taperd tap) and I used Peugeot m14 1.25 sump plug, £3. Winner so just drill it out and tap it. Sorted

You need to speak to a good chap called James walker aka. BDK race engineering mark he has many himself and tours on one raced one loves them with passion ! James@bdkraceeng.co.uk

Great stuff Gary, loving oven liner trick been there me self in past!

Personally I've reused circlips if they in good shape! And take your time fitting them , double triple check everything. As for oil O rings allways use new O.E.M and same on head stud oil gallery type, Allways new ! Copper washers just anneal them with gas torch red hot and allow to cool then they will soft enough to torque down nicely. I allways used wellseal assembly compound on my oil cooled motors never had an issue with bigger boost.

Loving this Gary, Amazed that these are still found in one piece! So many get chopped and messed about over the years. Top job captain!

The Best one, http://www.warpspeedracing.co.uk/

Stuart at warpspeed made them for me!

V-bands are great quick easy to remove and line up too! Use them a lot at work speedy connections rule.

Yep, billet tops will fix this issue or we have done another with notched frame inside, these carbs and dot head made 147bhp, so worth it for sure! I had them on my 750.g also same issues ,if you want to run 38,s then you will have to get carb top solution. As for tap pingel dual outlet only way to go, with slingshot you may have to dress tap mount area dished in buy 10mm or so.

Nice one. Had same issue, on my latest build.

I like many used Td04 Hl16T from Volvo t5R straight flanged made 210bhp nice simple unit and well made by Mitsubishi.

Airwolf, Sorry if you have allready been though the carbs few times allready it's frustrating for sure. Back to float needle valves have you replaced the o-rings on the outer brass valve body? And new needle valve too. I would change these as mater of course if there fresh new items it takes this out of equation. Mixture screws I would remove and check the pointy tips (taper) as these can break off blocking !!! idle mixture from getting through. Been there done that. Set all four mixture screws 1-3/4 turns out as base line, if you have done all this ignore my waffling on. Then bench Syncronise them. Easy job with 4 new clean drill bits as feeler gauge type of thing. Use idle adjuster to open your throttle up, to a point where all four drills can be slipped under butterfly's, then adjust 1-2 carbs until they feel same dragging on drills, then 3-4 same way, and finally each pair together nicely. and unscrew your idle adjuster screw to original Postion, not cv carb in piccy but you get the idea.

Air correctors, in lower bellmouths should be on standard carbs open! I.e not blocked my advice use a nice clean (single ) bristle from wire brush very fine and hold it in pliers an have poke about ,

Seen the progress at Stuarts SB it's looking very tidy indeed.

Motors com No nicely too, Do you think you had boost spike during Dyno time maybe.

Good for you Dan, Allways a positive thing to hear going it alone and being your own boss it's tough but rewards can be huge in time.

I've used AirTray method on my race f400 made huge difference on top end. Sounds amazing too.much easyier to make work that all that elbowed plumbing.

Mark I can sell you a gsxr 11 slingshot turbo allready built if you like? Black body work polished frame. Busa front rear ect.

I just happen to have serviced one of those that I may sell in couple of months cooky.
