Hello!

Post by Kalamari » Sat Jul 15, 2017 12:33 am

Hi. I wanted some sort of early 90s I4 250 or a Suzuki Katana so managed to nail both with one stone when I acquired this 250 Kat last year and restored it over the winter. I've since put about about 700 miles on it since the rebuild. I met Dean, one of your club members at Squires last Wednesday and had a pleasant chat about the bikes so I decided to sign up to your forum. So far I've been working with part numbers and snippets of technical information from half translated manuals and fiches from similar Suzuki bikes of the era so I could certainly benefit from the greater knowledge found here.

My intention in future is to swap out the front end for that of something like a bandit 400 so I can run a second disc and look at uprating the fork springs for a progressive pair.

Thanks for reading.

Hi, great to see another 250 kat owner on here, it's such a fun bike to ride (and i've got a kawasaki kr-1 tucked in the garage) if you need any help just ask, I've owned my 250 nearly five years now and i'm still surprised at how many parts are still avaliable at a reasonable price, only found out recently that a few rgv 250 parts from the 1991 L model (levers, grips, indicators etc) fit the 250 kat, mine still gets mistaken for a 750 or 1100 katana, even by bikers who claim to have owned the original !

Ooooh! that's nice. I have a 400 and prefer riding that to my 1100 if I'm honest.

Did you get that in about Oct from Ebay with a dent in the top of the tank? That was the last one I saw for sale.

I did put progressive springs in the front of the 400 - after talking to Hagon on the phone for quite a while we decided that SV650 (2nd version from 2004) were the ones to use. I also put YSS RG362 piggybacks on as my Showa originals were leaking. I saw a guy I know at the Bikers Classics in Spa the other week and he had some of these Gazi shocks on GS1000 engined GS750:
http://www.ebay.co.uk/itm/racing-rear-s ... SwwpdW6s4P
Which he thought worked really well. I might try those on the 1100 if the seller in Italy can get the fork bottoms sorted (he's working on it).

The other must do thing is to buy a set of Viton O rings for the carbs from http://litetek.co/Carb_Kit_Suzuki_GSX250_Katana.html and fit those. Modern petrol tends to kill the all the O rings in the 250 / 400 series and causes lots of running issues.

I do have the 250 / 400 Service and Parts manuals. I need to PDF, make searchable and upload to the forum members area. I'll put on my to do list.

I might have some competition for the best "Small Katana" at next years Euro Kat... :-)

Have fun,

Rob

+ 1 for the Litetek o-ring kit, that and using super unleaded fuel all the time (Esso supreme super unleaded has no ethanol in it at all :D ) has kept my 250 running perfectly for years, just a guess but an early rgv250 front end might fit without too many problems, i'm more than happy with the single disc on mine, its even more powerful than the twin set up on my Kawasaki kr-1 After looking at your pics I noticed that you have an aftermarket front mudguard on your bike, there is a tidy one on e-bad at the moment for 30 quid and your fly screen is clear, I got a really nice light tint one from webike in japan and it only cost £18 including post and taxes

Thanks for the welcoming words, everybody.

It is indeed the one that was on ebay in October with the dents in the top. The tank inside is very clean but when I had it blasted, another dent that had been filled previously in it's life was discovered down the right hand side. I managed to source a stock exhaust from DK for quite cheap. Still have the stainless 4-into-2 ones which to my eye look like they were some sort of home made job. There's a BS mark that looks like it was crudely scratched on with a drawing compass.

I have the original Kayaba rear shocks which were leaking and I looked at refurbishing them but for the sake of economy, I just opted to put a pair of Tek ones on. They're hard as a plank until they've bedded in but after about 500 miles, they're really very good for the price.

I've already got the Litek o-ring kit fitted since the carbs needed overhauling anyway. The airbox to carb rubbers weren't attached when I got it, it ran and pulled fine but strangely, as soon as the airbox was properly attached the engine just wanted to bog down and die, even minus the air filter. Turns out the carbs had been re-assembled incorrectly and parts were missing. It's all been sorted now though. I always run super unleaded just as a habit of living with two strokes and concerns over ethanol.

I actually still have the stock front mudguard but had a bandit one painted up at the same time as the tank (rest of the bodywork was good enough to leave alone). Still on the fence as to whether or not I prefer the way this one looks so I might yet put the original back on.

Overall the bike was in better condition than I expected considering it was a blind bid for cheap. The frame had suffered in the elements and needed a bit of welding but for the most part everything was fine. Unfortunately the original screen acquired a big long crack.

Bike looks great, well done on the resto, not many 250s about so keep hold of your original kit if you do modify it.
Don't worry, I never make any modifications to my bike irreversible. ;)
