No he just propped it up , but I rang him and told him to just put my exhaust on ....as that's the only change been made ...he rang before firing it up an I barely heard it crank before she fired up so happy days he hadn't trashed my bike ......but guessing the end can he has is really restricted or blocked , thanks for the replies and suggestions ...just gotta sort out the rich running now

Got a bit more info so he went to change the plugs for me with it smelling rich but didn't have a socket small enough ...so he removed the air box,and the 2nd coil realised his socket won't fit and put it back together....from what I've seen on video call everything is back correctly, no mods standard filter , it's was a micron end can from po

Hi folks hope all is well , so 99 gsxr 750 was running great only issue was it smelt really really rich , anyway leant the bike to a friend for a bit and in return he gave me an original 750 end can which he put on , so he went to ride out today and it wouldn't start ....when it did it sounded like it was on 1 cylinder and now it just backfires really really loud ....I'm stumped as when I dropped it off it ran really well

Not seen it yet but got it saved to watch later,ain't had any time to play yet though a friend of a friend sold me his old 750 calipers and MC so put that on .

You can buy rust converters that will stop the rust , sand away what you can then apply the rust killer then repaint, some won't even damage the paint ....some will strip it right off so do a test 1st

Or I'll lose my mind trying so if I go quiet please send help to the local Staffordshire asylum

All new steel hoses,washers,and banjo bolts all done up with a torque wrench. Got it all steipped off the bike now as I'm gonna swap the whole system out , so now I can bench test the whole system over and over and just see whats causing the issue

Might have to grab those thanks , just stripping the brakes off now gonna do one last rebuild ......just incase , I have noticed this scratch in the MC .....not sure if it would cause the issue I'm having

Yeah that's what I'm hoping to get , shame would have liked to keep it as stock as I can (even though someone's put an awful under tail thing on it .... luckily one that keeps the original rear light)

The new pattern lever came today ....it is a bit better ....takes a lot more force to pull the lever to the bar ,but it can be done Thanks for the help and suggestions folks but I'm gonna just swap the whole front system .

She is an old girl now ..I don't know if these levers are prone to bending or just snapping , maybe it's a combo of worn parts and a slight bend , I've ordered a used lever and a set of pattern parts so I can compare .

I'm in Staffordshire, everyone I know that rides is stumped , ones an ex bike mech lol .

Depends on the visor ....I brought a plastic headlight restoration kit for this kind of thing .....turns out a new visor was £7 cheaper lol

Yeah it does feel real sketchy shimming , think I'm just gonna replace the front brakes completely.

Lever end is a little worn ....piston is fine ,I've noticed the adjuster wheel is also a little loose ...so maybe a couple mm here and there is all adding up . I'd love to ride to Scotland...but when it warms up a little

Would be a great ride though

Yeah this is gonna be my last resort and short term fix until I can either solve the issue ....or replace the entire system

already on it .....but I don't own a drill bit or tap small enough , so gonna get them ordered

Well I took for MOT and it passed all the brake test it was just the lever travel ...as it could touch the bar , had a play today another bottle of fluid down and still the same result.......however I stuck a nut between the MC piston and the lever ,6mm was too much it made the bike very hard to push , put roughly an 8mm bolt between the lever adjustment bit and that was better but not as good as shimming the piston . Anyone else got an old srad to compare levers ?

Simon , yeah got the little membrane that's in good condition no tears or holes . Ride, yeah ive double checked things like that ....it's usually something like that to catch me out , but all is good Stu, yeah it's the tokico calipers, I keep looking for nissin calipers but can never find any that will fit

Yeah my 1st thought was maybe a 600 MC had been put on by mistake....but measured the piston at 15.8mm which is the right diameter for the 750 , the stroke is really long then it applies pressure right at the last minute.....even with the lever off and me using something else to push it in ....I'm out of ideas now.

Just tried vacuum bleeding ....again and still only gets to a certain point and nothing .....tried reverse bleeding but could not get the fluid in ....fresh out of ideas now .....might just search eBay for a MC

Hi thanks for the reply , yeah it is puzzling indeed , the new MC rebuild kit I put in decided to die ....so that was fun , although I think the seal was a little too large so it must have snagged an tore , new MC kit went I today but still pull the lever back to the bar (easily) .......is there any difference between a 600 and 750 MC ?

1st pic is where it sits (on number 1) 2nd pic is where pressure really starts to build

Still no joy even with the correct caliper this time ...I've bled the things every way possible, and I can still pull the lever to the bar , it's about half way when the brakes bite ....they pass an MOT brake test but , fail MOT because the lever reserve travel .
