The biggest I've run is a 16. I think you'll have to fab a different case gaurd for a 17 and an 18 requires modifying the cases, or so I re-call.

BTW, Kawi runs 14-16 on Chicken's Supermo bike.

I'm running 15 front and 38-42 rear. I think the 500 frame has room for the 16 up front, but the 250 with the 500 motor in it is a litlle more tight. Anyway I don't need a bigger front sprocket, top speed is allready around 125 mph  :twisted: .
 I'll have to check out those Talon sprockets though. Sounds sweet. Thanks for the tip, making sprockets yourself is a pain.

I have run a 16 front on mine with the standard case guard :)

I don't know about bigger than that but I have the Talon trade catalogue in front of me and those are the sizes they make.

On a slightly different note, if any of you need a really weird sproket that you cant get hold of Talon will take your old front sproket and cut the outside off and weld on another ring with teeth.
If you send them the rear sproket information they can make you them up also

Yep

Not all good... :oops:

I went testing on a gokart track (ultimate fun on a supermoto) and I found out that my tank was leaking  :cry: . I suppose the chemical metal and epoxy didn't cope well with the plastic tank and the heat from the engine. So I'm building a new tank in alu. Pics will be posted next week. The bike handles very different from the kx500. The chassis is more stiff and the bike steers very fast compared to the big bike. The suspension is just way better.
 The engine still performs very well, I've been fiddling with the jetting and now there's allmost no difference in performance from before I cut and turned the pipe. The kick backs persist and I'll have to wait until winther to get that fixed.
 New springs are on the way, cos the old are too soft.

I have heard that you can change the shape of plastic MX tanks by heating the bit you want to move with an electric decorators heat gun but heat it up slowly cos they can melt if you go nuts :shock:

Might be worth practicing on your knackered tank before having a go on a fresh tank

I had a friend that had a new KX250 and a friend of his sold him a new FMF pipe,well the pipe was so close to the tank it melted a hole in it (turns out we were at Washougal national MX race so FMF looked at it, told us the pipe had the mounts welded in a jig that was out of alighnment and gave him a new pipe but wouldnt fix the tank.Turned out his "friend" sold the pipe because it had melted a hole in his tank but didnt mention it untill after the fact,nice!)My father inlaw owned a body shop and gave me some epoxy(dont know the name of it,was back in'95)after my buddy had tried every thing to fix that hole,well the epoxy I got held for years untill he sold the bike and still is as far as I know.So you may want to try a body shop or look for some epoxy that works because some where out there there's some that works.Ty-Davis had a custom aluminum tank on his KX250 years ago,but I hear youll always have leaks popping up no matter how good the welds are,let us know how it goes and sorry I couldnt give a brand name for the epoxy.

Hmm,

I know you are not allowed to race with a metallic fuel tank in Sweden. I assume the same applies in other countries?

Well it might not be allowed in motocross but in roadracing and supermoto it's another matter (I just checked the regulations).

Well it took me long enough but my new tank is starting to take shape. It's not finished yet as it still needs a hole to pour in the goddies. Pics are in my album.

WOW!! Can you even get a 17 or 18 on the bike? I know Team Green raced Baja with a 16 up front and would imagine that was a tight fit.
Quote from: demographic

You can get front sprockets made by Talon engineering in 10-18 teeth


I think you have to remove the case saver guard thing on order to fit them and as far as I know they are possibly for KX engined MX sidecar outfits :?

As KX engines get used for all sorts of things I assume that Talon makes sprockets for all kinds of things also.
