The pivot on the frame and the pivot on the swingarm ought to get further apart. Dogbone pulls on triangle which pushes the shock. Along with the swingarm moving up as well. Does look a bit funky though..

If you really want him to build a frame for you I think you're best bet is to build a personal relationship with him.

Based on a blade one

Wc tanks do fit but they overhang the frame rails a fair bit, I decided not to use it after mock up.

Hi All, Just finishing off a 1984 GS125 for my youngest. Had the loom on the bench and had everything working but now it's back on the bike everything is fine except for the indicators that don't work at all. Relay seems fine. All bulbs light when attached to my bench supply. Measuring 9.5v at the relay - is this an issue? Should it be 12v? If so, any ideas what might cause that and would it be enough for the lights not to work at all? Any advice welcome - it's driving me mad! Cheers, James

Yep. The ones I got got are the latest versions so should be much better. Those early ones are so blunt and basically as cast it's not surprising they fail so easy.

I'm hoping to go over tomorrow to have a look at it and see about soldering a resistor in. As far as know though, it doesn't have the gear selector switch. Just neutral . No speed sensor on the drive sprocket just a cable speedometer. He's tried a few speedos and it didn't make any difference . But thanks for the info.

My mk1 B12 ignition switch needs replacing, key can be removed with ignition switched on, and don’t even need a key , a screwdriver will do to switch it on, also I have a non locking gas cap which is quite fiddly to use, a new full lock set of ignition switch, locking gas cap and seat lock can be found on Eblag for under 25 quid, much cheaper than buying used, but are they any good, anyone any experience with them ? I’ve found not all cheap Chinese stuff is crap, but £25 seems very cheap https://www.Eblag.co.uk/itm/353688280073?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=NTXhao1RQEC&sssrc=4429486&ssuid=ZZc2CzMpTMO&var=&widget_ver=artemis&media=COPY

Those dogs are Donald Ducked for sure. Sharp square edges are req'd for positive engagement & retention. Even better is an undercut as later gears got.

Dunno about Martek directly but heard mixed reports. Try searching this site, this section even . GIA have recently gone tits up so now not an option for anyone

Hello everyone, recently bought some stuff off Mark Walker, no issues but got me thinking about possibly buying one of his Alloy tube frames. He has given me a price for the frame, and I realise it will not be a cheap build. Probably looking to buy a frame and a tank to start off with but thought I would ask here about what he is like to deal with and how likely he is to keep to a stated delivery time. I take it that there are no issues with quality. Any thoughts would be gratefully received, obviously a lot of money to lay out so just trying to do due diligence before I start talking properly with him. How does he compare with GIA pricewise. Many thanks Rob.

here is a bit of information on how to deristict the gsxr 400,as they have used m-max boxes as well to fool the cdi thinking its still in a low gear when in 5th and 6th.-But they are easily overcome by soldering a 1.5k Ohm 1/2 watt resistor in line with the green/yellow wire to ground which is what you could probably could do to yours to get it revving in 5th and 6th again. The resistor is a mod that owners use to lose the speed restriction from the poxy gear selector switch that Suzuki put on the bike to make it Jap legal. (put the 1.5k resistor inline with the green/yellow wire from the cdi to ground )

Well lads, im after buying an ‘88 750 slingshot frame for a good deal up the country to build as a 90’s streetfighter 7/11. I want to start gathering bits for it so I was wondering what options i have for petrol tanks. I assume all of the oil cooled slingshot tanks are the same but is there different tanks that can fit? W/C tanks in particular and gsxr400 tanks also and pics ofc if possible.

Just going through the trans. Was expecting more damage. Shift arms look decent but will double check. Got some new old stock 2nd and 5th gears. Putting the Factory Pro dentent arm and stiffer spring in while I'm in here.

My 750g jdm came with a 2pc seat also

Pretty sure all jdm slabbys have a fuel gauge.

This is similar it's r1 on one of my slabbies.

This is the linkage on my K1 1000 which is different to that. That does look like it should work though.

Wondering what sports bike is it based on But if its GSXR thou 2010 on its configured wrong and the link arm is to long But maybe "bad H word" based

after staring at it for some time i can see how the whole thing works but it looks like the shock doesn't compress much !!!! but if it works, it works

Can you or anyone explain how that shock linkage works because I can't! - whichever way the arm moves, the shock doesn't ! ! ! Confused!

Hi, yep mine is exactly the same....jap import with 2pc seat,weird jap writing bulb on idiot lights ,and a fuel gauge ( don't think uk models had that )...I have no idea why they changed seat...perhaps they had a load left over ?

Wraith , I may have an old gsxf 750 cdi knocking about in my container , just gotta get it here. Don't see so many B⁶s about here,but there again they're not everywhere like they used to be in the UK. See a lot of Hardly Movingsons and ADV bikes here.....no accounting for tastes lol. I think it's just one of those things I've gotta play around with...I hate any restrictions on any bike....

Had a right chew on fitting the oil lines to the head kept clashing with frame tried umpteen fittings ( luckily enough a good mate is a good rich dealer) ended up with done head bolts and had to put a small indent in frame
