Suzuki GS550E '78
« on: Aug 06, 2012, 05:47:21 »
Been on this forum for some time, not had the balls to upload anything as there are some top guys on here and this is my first foray into modifying.
I bought the GS from Ebay for 400 from an old guy in Exeter (UK) who buys up duffers, rebuilds and sells on for fun. He said he'd made a loss on this bike but was happy that he had some funds/space for his project. It was a good runner, needed a bit of work for MOT test, but I was happy. It has been my intension to have an older bike for some time as a lot of my friends have velos, guzzis, panthers, nortons and triumphs. I can't afford any of those, so looked into something Japanese. My first ever 'proper bike' was a GT200 X5 in 1992 so though a Suzuki would have some nostalgia for me.
Picture shows bike as I bought it.

First thing I did was remove the high bars, at the time I had some MX renthals lying about so I put them on. My friend wanted the seat cowl so I took it off as I didn't want it anyway.

The clutch was really heavy, so it was stripped and checked for warping, all ok, pushrod was ok, cable was new. Turns out the springs are heavy duty, replaced by PO. I onlt put three of the six back in, now I have a usable clutch, and it doesn't slip, surprisingly.

Rear caliper was seized, after boiling a pot for 5 minutes and a squirt of WD40, the pistons popped out no problem. I cleaned all the flaking paint off it too.

The bike came with Hesketh V1000 gauges. I really like them and my mates say they are quite querky as Hesketh are well sought after and expensive bikes. They don't really fit into my 'vision' for the bike so they may have to go eventually. Been offered a Smiths 3" speedo which is proper vintage from a 50's Brit bike (he doesn't know which), but I don't think the ratios will work and it has a dent in the chrome surround. I am still considering it.

Forks were well dodgy, the front calipers also had a lot of flakey paint, so I wire brushed them.

Also during this time, have replaced the headlight mounts, the indicators, front brake master cylinder, throttle and grips. It now has clip ons from a BMW R60, they were a bit short so I put 5cm long bar ends into them. You can also see I have added a mirror and cut down the front mud guard. The front disks have been drilled with 16 8mm holes either side. these were cleaned up with wire wheel before drilling. You can see this better on the above pic.

I replaced the starter/kill switch to the top yoke using a MX switch I had. Cleans up the bars too. I lowered the gauges. The forks look really lowered, but the PO had put fork extenders on them. I shall return them to stock asap. Forks are only 4cm lower in the yokes. Still handles really well, despite the changes to the front.

Bought this seat, my first attempt at making a fibreglass seat following Lossa Engineerings method failed miserably and cost me about 40 in resin and fibre, so I thought I would save myself the trouble and cost and got this one.
It is really for a Honda so the mounting points dont match up. This is my next job, moving the battery under the seat hump and creating brackets to fix the seat to the frame.
