Go Fast TM125 Tips Needed

[Graeme M]

Thanks for all the tips guys. The first few tweaks were put to the test today at the DT practice day and the TM ran real well. I was VERY happy with the improvements, and in fact I have completely changed my opinion over this bike. It might be average on an MX track but on the DT it is brilliant. It just feels so damn stable and happy to hammer through a bumpy turn without a bobble at all. Now, just a little slow up the hill, but we have still more stuff coming so I am guessing another month or two and a CR killer we just might have. Bring on the Nats, I reckon I'll be in with the pack at last!

Whats the go with the ports ? is that the same deal needed on the 250 or are they just dull ?

I bought a 74 Husky in October last year and It runs on Methanol. This is my first bike I've owned or ridden running on the gogo juice it is just amazing. To ride a 125 that has power in all ranges and is faster than most 250 is sometimes frightening because you just don't expect it.
If your going to continue racing dirt track get Chris H to modify the suzi to methanol, he swears by it on his CR125 and other bikes. I blew up the 125B twice at Canberra when they used the long track, I think you should consider the methanol as it isn't as difficult as it sounds to mix fuel castor and keep moisture out. Also they run so cool and don't wear as quick as long as you you flush it out with petrol after a meeting.

Yes, been thinking about that but it is a bit of fiddling around. You're right about it running cooler tho, the TM got a bit hot on Sunday after about 15-20 laps. I've got to do a little work with the ignition and to fit a 34mm carb, so I'll see what I reckon about it after I've tried those changes. You still on for CD5?

Please tell me your not running 91 ULP, as ULP in general will send temps through the roof.With a decent ignition alleviates this a bit by dumping heat into the pipe.Higher oil ratios will greatly assist in wicking away heat.Should pull a 34mm no problems.

[Graeme M]

No, not 91 ULP. But Caltex Vortex Premium 98, which I'd heard wasn't bad for a pump fuel.

Graeme, you need one of these to make your bike fast....   

[Graeme M]

Hah, that's pretty neat alright. Yep, she'd fly with that on her...  You UnZudders and your decals.

I love ya graphics DJ  . If I rode a Suzuki I would swipe them off ya  .

I would not recommend taking any more than 10 thou of the head-this will obviously raise the compression,but you do need good fuel to make the most of it-it will also add a little bit to the bottom end.Don't forget Peter Campbell in Goulburn for getting most any engine to perform at it's best!

Hmmm... the big day approaches. One small problem was that although I'd bought a heap of 1.00 over pistons and rings, the bore was just a little too far gone to clean up OK so have had to go to 1.50 over. Found a small crack which I think was contributing to the over heating, that's been fixed too. The carb is jetted and ready to slip onto the RM-S manifold, I've slipped on a Uni Filter pod type, I've got a nice new head to add to the equation, and it's looking good. I'm hoping I can get it all together in time for the next ACT DT Club Day on August 3, failing that I'll ride it on the practice day at the HEAVEN MX the following week. It'll be very interesting to see how it runs.

In the meantime I've thrown a fresh clutch and springs at the RM125M and I think I've got the springs on the YSS shocks sorted, so we'll see how it runs this weekend at the ACT MX Club Day.

I love these little Suzis...
