Big bike frames

[Scotty595]

Depending on how sorted it is it might be about the same as buying a cheap one and doing it yourself. To get back what I have put into my bike (you've seen it, nothing flash) I would have to get about 2 to 2.5 k for it. And that's taking into account the fact that I paid $500 for the bike to start with. Most expensive thing on mine is the GSXR 250 wheels. Budget on about 300 without disks and 450 by the time you have them on. Assuming you can find a set. Mind most of what I have spent (including the wheels) is just to make it look like a proper little racebike. Doesn't go that much better than a stock one.

Yeah one i lookin at has got slicks on already, race seat etc etc so good for bucketing, if i can get it might be the go, will have a look round too though

. . . or if your bored with selfharm and really want to feel some pain a TF100 will do the trick. . .

Funny I was talkling about that with a mate yesterday & he made a good point, they aren't that bad really. When I started ~90% of 2 stroke F4 bikes were TF or TS based & there have been a few goodies. Ziffles Pepsi, Ram's Red one & heck Speedpro's was pretty potent too. They are the same layout as my RG50 just not watercooled. That can be changed.

I must be a little masochistic then; I'm trying to get power from a TF125.

[F5 Dave]

Actually I remember at Wanganui before 125s were bucket legal Mike had a 100 barrel & a 125 barrel for the clubmans class in the old days & I remember him making some Pantahs look pretty shabby

Well I guess I’m masochistic (for a rather long time... being able to remember Ziffles and Rams bikes) and sadomasochism, not only personally destructive but have encouraged other in the same direction.... the TF/ts is a great two stroke foundation; plenty of parts and options.

i have a NSR MC18 framed GS125 motor, bored to 145ish, with a jacked up rear end thanks to RCE from the spec off the NSR-WORLD web site, some F3 Japan spec arrangement. It probably is too heavy but I know whats important.. phat tyres that look good... a bike and rider big enough to block the track to restrict the opportunities of other riders to overtake.

Haha fair enough. might look into doing a cbr250 bucket with a 2stroke, heck i might even do two if i get another frame . And then maybe ill get a rgv150 and chuck a loncin in. -which model is the best bet for the rgv150? cant seem to find any with decent power.

might be struggling to get one of these down to 100cc, though it has been done... check out the MNZ bucket rules via Skunks website:

TF100 fits nicely in a CBR frame.. in saying that so does just about anything for that matter.
The newer RG/RGV150 frames (post 98) are steal and are very heavy (surprising more than a fxr frame) unless you can find one of the older RGV125 Alli frames (91-93 slingshots but they are very rare, not the new ones i.e. not what you see on trademe)

We need some of the engineering types here to start making some bucket frames.... TZ???? maybe something like Fred McLean's FREPIN TZ350's !!!!!

Mmmm, nice frame. I see room for improvement though...

Dont need to get them down to 100cc as they are aircooled you only need to get them close to 125

IN terms of a replacement engine though. Something like a loncin.

What would be good fit with good power?

True that sorry I was thinking RG150....

How easy are TF100 engines to get hold of? are tf125's legal as well? what sort of power do they put out and are they cheapish to rebuild?

This may not be accurate !
TF are farmbikes, they have tiny ports and take heaps of grinding to get them to go, TS are the same but have way better porting.
TFs are common as mudbugs, you can buy a motor for $50 easy.
125s are more common than 100s, 125s are legal for buckets check the rules
for about 4 grand you can buy a band new TF mmm shiney

a dime a dozen, one of the most sold farms bikes in New Zealand (both the TF and TS), the only major difference is the inlet porting and the piston sized (50mm on the Tf100: 55 on the TS125). Both engines are based on (and probably the same) moulds and the earlier 75-76 RM125 motors (though less ported to make farm bikes). If you were lucky enough to find the 78-79 DS125 (again the same as the above TS) the porting replicates the RM more closely so less filing will be required.

Parts, well they are a popular engine and haven’t changed in 30 years so most wreckers will have one or two sitting around; the only issue they really have are the cranks aren’t that great for big revs; good two-stroke oil and they may last a while; and the crank nut has a tendency to come undone (solutions aplenty to solve this)… Speedpro and others has shared their experiences in a earlier thread (http://www.kiwibiker.co.nz/forums/sh...95575-Ts-tf100) regarding these potential issues.

All in all, a lot can be done to any of the fore mentioned engines (and easily and well documented, Bell’s Two stroke tuning “RM road racer”) to get good level of power that lays the foundation for a good bike (not in the realms of a fully tuned FXR, but they can be quite quick in the right hands…) and are generally in the form of a cheaper option.
I’ve had mine for a while now and outside of some stupid issues (more to do with me) the engine has been good B grade engine. But maybe I’m being sadomasochistic again…

as to the rules on 100 vs 125 two strokes, I would suggest reading the MNZ rules. here is a link if you haven't found it already: http://www.bucketracing.co.nz/rules.php?pg=rules

Good luck with your bucket project. Once you start you can’t stop.
