Motorbikes ( gearbox probs)

Got a major prob with the gearbox of a GSXR 750 , can't engage 6th gear at all , started of as a sort of false nuetral thing and gradually got worse. Apparently a bent selector fork. Had a look at dropping the engine myself but too many specialist tools are required.
How much is my local MC mechanic gonna charge to remove engine , split open gearbox fix and replace engine (no shop I have foned is willing to even give a rough estimate) I don't mind paying the money for the work but I aint paying for some spanner monkey taking a shit every hour and yapping with the local schoolies. 😛 Also the parts and gaskets etc will cost around £500 , but I'm bloody skint innit.

Where are you? My old man has a motorcycle business and can more than likely help you out…

I'm probably a bit out of touch, but I've done the gearbox on my GSX100 a couple of times, I can't remember using that many gaskets. If I remember correctly it was a case of engine out, split bottom casing, work out which gears/selector forks needed changing. Then ordering parts and build it up. Probably took me two days, taking my time, including trip to work to replace gears on shaft.
Could you take the engine out yourself, then let them do the gearbox, I'm sure they'll charge a couple of hours just for taking plastic off and on.

I' m in the North of Fife , Scotland.
Can't get the engine out as I need 2 special fitting sockets for the bottom bolt/nuts , need a sump gasket and clutch case gasket for a start as I dropped the oil just to see if there was any teeth or large metal deposits in the sump and the clutch is best removed as it's on the drive shaft.
My initial plan was to remove the engine , split the gearbox and fix myself then possibly get the engine installed by a bike shop. All the wiring and hoses will (would have been) labelled , there are sensors for everything and the fuel injection makes it a bit intimidating for a unskilled **** like myself , even though I have a Suzuki workshop manual. 🙂

You're not far from my old man. He can collect too as he has a motorcycle trailer.

Here's his website http://www.johnsengineering.co.uk/

Feel free to give him a call to discuss, he'll be able to sort you out – a spanner monkey he most certainly isn't, a darn good engineer he most certainly is. I'll have a word with him if you like?

Cheers

Japanese inline-four crap….
Not very helpful I know, but it has to be said 😉

Zedsdead , could be a little far away but I would be grateful if you could get me some more info. Nice website btw , looking for any Turners? That's my trade , machining mainly wellhead equipment for the Oil and Gas industy. 🙂 Wish I could turn my hand to some restoration of those old British bikes , but I'm too impatient.

Hey Juan , I've had a load of Jap bikes singles V-twins and inline fours , 2 and 4 strokes and never had a problem with any until now , funnily enough this is my first Suzuki , really wanted a Fireblade but the prices are too high on Honda's but tbh the one's I have owned previously are the best built of all the Jap stuff.

Iv'e gotta say the two gsxr's Ive had were the sweetest gearboxes out of all my bikes.

Sounds like it's worth buying some specific tools and just getting on with the job. Ask a mate to help you removing and installing the engine. Label everything up and like you say you've already got the factory manual, so it's no excuses really.
Otherwise, if you need the bike as transport give it to a reputable bike shop and accept the issues that go with the arrangement.

There's not much in between!!

Purple, I'd suggest giving him a call, my old man was in the oil game for years and still keeps in touch with a lot of people. He may be able to point you in the right direction…

Also, feel free to give him a call for advice about your bike – he'll be happy to help.

What specific tools is it? Usually Suzukis use castellated nuts which you can either make out of a socket by grinding material away, or just ignore entirely and whack round with a flat-ended punch. Though i'd recommend the former obviously! If you can send pics and sizes I reckon I've probably got at least one of what you need, made up a set to get the engine out of a TL a couple of years ago.

Also how old a GSXR? Considered just finding another engine? There's no shortage of sports bikes with no front ends out there waiting to be organ donors after all.

What year is the bike? Maybe it has a casette type gearbox which is easy to change.

Bike is an 03 plate , but only 8020 miles.
Seems an easy fix once the engine is out , which is looking good for a bit of DIY as a friend of a friend runs a race team and has the tools to get the castle nuts off , woo hoo.
It's definately a bent selector as some GSXR's from 2000-2004 were prone to problems with 2nd or 6th gear , everyone I have spoken to has said selector as the prob first started with a false neutral and progressd to not engaging at all at high revs. A quick fix I was told is to get the bike into sixth gear and stamp hard down to 5th and bend the selector back the other way , but this sounds a tad brutal and isn't really sorting the problem.

There's a days work in it so I reckon £200 labour

whatever you do, don't do that & especially don't do it when riding along – no one would, would they? 😯
