A few questions

[Davenc30]

Hi all,

You probably get this all the time, but im keen to have a go at buckets ive just got a couple of questions.
I have a old early 80's gs125 in the shed that runs and that's about it.... is it worth using that? by the time I upgrade to disc front (if that's even possible, id imagine id need forks with calliper mounts and different wheel etc) and make the suspension usable, I suspect I could have gotten into a better bike to start with?
Also I am a big boy at 93 kg. what would be the best option for a entry level bike id be very happy in mid pack b grade. I've raced my 600 in clubman's and enjoyed it but prefer closer racing and lower costs to a battle of the cheque book.

Im a qualified car mechanic and im currently a motorcycle salesman in the Waikato so pretty lucky as far as parts and building bikes goes.

Ill be coming to the next round in Auckland to see them in action and to pick some brains.

Thanks in advance.

If you want to go racing, without too much fluffing about in the garage.
There is one bike for your needs, and it is by far the most popular.
FXR150 <- You can't really go passed them for ease of racing/reliability and pretty good handling/potential.

Its the bike for you.

FXR150 is the bike to get !

PM Pumba if you want help with transporting
950 FXR here in Cambridge. If anyone wants it and needs a hand yell out http://www.trademe.co.nz/a.aspx?id=733318622

There is another one for $1250 as well http://www.trademe.co.nz/a.aspx?id=733700636

Haha a fxr was my first bike. poor old things. so gs125 is a waste of time even if its bumped out to 150cc?

What mods would you do to a fxr obviously a weight reduction, exhaust, intake and jetting, tyres, gearing?

Thanks guys

Not a complete waste of time. But your stuck with crappy wheels, crappy suspension, crappy tires (because of the crappy wheel sizes), and underpowered. Where as the FXR standard has a okay level for all of these.
The FXR150 provides good feedback.

Standard mods, are underneath exhaust (the stock one will drag on the ground at a large lean angle), there's a thread about how to do this. Its quite easy. Shit lines up well with old fairing mounts etc.
New Carb to remove the CV carb (Poor throttle response) - You can get them for sub 100$. Obviously jetted to suit.
Gearing isn't a huge issue, but most people will shorten them up alot. I'm running 11/45, standard is 14/49 i believe.
Oh and you will need to raise the pegs and buy some cheap clipons, or put them under the top triple clamp (reverse the sides to make fit).
To get it in a more agressive postion.

Again, if you wanna mess about in the garage, go ahead and do a big ass conversion on the GS125, big bore it, new wheels tires, piss about with the forks abit. And after all that your'll be lucky if its as good as a stock FXR150 (4 valve DOHC btw). Actually you wont be, FXR150's can be ridden seriously hard in pretty stock condition. Awesome bikes.
If you want to go further you can contact GPRnz and they will get you a little above 20hp (stock is about 12.5), for a reasonable price. (Porting/CAMS/Carb/Big bore to the biggest limit).

The FXR150, saved buckets from dieing away.

I see, well I guess ill head along to your next round and see if its for me, do they have 'have go days' or practise days? I could attend?

I'm not sure there format up there but i believe there is usually a practice day before the race day. Contact them and they will probably sort you out a bike to give it a go .

"Try out rides can be arranged. The club has a bike (a Suzuki FXR150) that may be used, by arrangement with organisers, on practice days. Racing licences are required for competition but you can try out on practice days without one. On race day, one-day licences are available at the discretion of the steward on the day subject to MNZ rules."

Thanks heaps mate.

Unfortunately next practise day is the Saturday of Fieldays, so ill be working........ Guess ill have to just go watch on Sunday if I still want to be around people after 4 days at fieldays.

you don't have to wait long though for round 1 of the next season; 5th-6th July. So gives you a couple of weeks to put some nylon on, wire the sump plug on your GS and come along. Yeah FXR's are great and you may well end up on one very soon. I would definatly say invest a bit of your time and $30 bucks on some nylon and get your GS up to scratch. Heaps cheaper than an fxr gives you a good chance to figure it all out before investing $1000 + on another bike.

Good call, are there many under powered bikes like the gs125 in c and b grade? or would I be the only one out there with crap suspension and drum brakes? I think I would need to do tyres at a minimum.

Yeah sorry i was a bit negative of the GS125, if you get it track ready, you'll still have lots of fun and with some good riding might get to peaky point of B grade.

haha nah its ok man, your probably right it would be a fine line between wasting money and having cheap fun. could go either way, would be a great option for a 50 kg kid, but may be a different story for me....

[Pumba]

.....it would be a fine line between wasting money and having cheap fun.........

And there you have hit the nail on the head. I personally really hate the standard answer of "just get an FXR" when guys starting out ask. But truth be told, even though the outlay is more up front, the effort required to get some of the old bikes track ready just is not worth the effort.

Sure make the GS safe for racing and go out and have some fun if you want, but personally I would even think of going any further with it, because if you enjoy it you will very quickly tyre of the limitations of the bike and either be making major mods (engine, wheels, suspension.......) or buying somthing better. Unless of course you are one of those guys that likes to be different and wants a challenge, and lets face it there are a few guys out there that make ther old shitters go just as well (sometimes better) than a standard FXR, but it is not an overnight process.

I dont think on a GS you would get anywhere near the pointly end of B Grade in Auckland at the moment though.

In terms of what needs doing to get an FXR race ready. Do a search there are a shit load of threads. Also I am in Cambridge so if you want to come round and look at a race preped bike and talk shit about bikes in general just yell out.

[Davenc30]

Is the field literally full of fxrs and modded/hybrids? Is there nobody out there on old standard shitters with drum brakes?
