Starting out & have lots of questions

[Nobbsie]

Hello everyone.
I have decided i want to learn to race buckets/build a bucket racer. Im not concerned at this point about being the best, fastest, or anywhere near the front. I want to learn to ride on a track, keep down low, fundamentals, and about frames and two stroke engines. I have a tf125 i got for nothing in very good order. Is there anywhere i can find the regulations on whats ok and not ok in terms of building? any advise or help would be much appreciated.
Thanks all
Nobbsie

go to the track.

contrary to you may be led to believe around here. not all motorcyclists are f*cking a55holes.

Hahahaha yea. Anyone know when the next day up at Kaitoke is on?

Hahahaha yea. Anyone know when the next day up at Kaitoke is on?

Its normally the 3rd Sunday of the month but not this time, we are having this next one on Saturday.

Details on events can be found here (We run with the KArts).

Full Rules can be found here:

You need to read chapter 10, chapter 24 and Appendix D in relation to machine spec, reading the rest is a good idea too.

The main thing you need to know is, no competition engine part,s max 24mm carb and no watercooling for over 100cc 2 strokes.

Rock up to the track and have a look, you'll soon start to get an idea of what others are doing etc...

Sweet thanks so much i will head up on Saturday.

Actually the main thing you need to know is for kart tracks we need to run protection for the track to avoid gouges. Fortunately there is a sticky thread above this with a decent enough guide to get you covered. Oh yeah & noise is an issue so you need a decent muffler, not some cobbled together bean can.

But apart from that there are heaps of people who will help answer questions etc. Welcome.

Sweet as thanks man

OHH and if anyone has an old tatty TF125 manual lying around who wants to sell it, i am looking for one.

Thanks for the clarification hahaha would have been the only one out there this weekend hahaha

Also looking for all and any tf125 engines

Cheers Chris

Before you buy more stuff my solemn advice is to allocate some money for a crank rebuild. I've always found an old 2 stroke that has been sitting for a while & then pulled out and asked to perform racing revs dies shortly after. the rod gets a bit of corrosion & that wears off the plating & its all over. rebuild it properly & you should be able to forget about it after that. 2nd hand cranks are false ecconomy if you don't give them some love.

A new rodkit won't be expensive. You might ask Rick52 what he runs in his. From there you can determine what revs are safe to run & all engine tuning is based on that.

The TF will std produce power at say 7000rpm. Waay too low to make competitive power. That can all be changed.

If you haven't read it already find a copy of Graham Bells performance tuning 2 stroke engine book & read it every night. It is old & out of date, but the very best place to start off (after reading the rules).

Soo true. 2nd hand cranks will only end in tears.
Plenty of replacement options and also plenty of piston options to improve performance.

The RM125 of the time shares a lot with the TF/TS 125 apart from the fact that they are a lot more mild on port specs. Bell talks a lot in the version about RM modification for road racing; and while not ideal in terms of modern theory, you will find it is a bloody good starting point.

On top of Dave's recommendations id also follow crank with mains and seals. Factory they are rubbish and are the two most causes of failure, seals will likely result in piston issues.

Handling and brakes... Cheap option. Pick up a FXR frame, everyone is converting but as a start they aren't that bad and a TF/TS fix in no worries...

Just found it today will print it off tomorrow.
Thanks heaps for the advise guys, it is hard to work out where to start, but I'm thirsty to learn.

Qualman was just advertising fxr bits in bit thread.

disappointing thread - by the title I presumed you were a young man asking for advice on how to satisfy your partner sexually.

Still there are many parallels that apply to racing:

Try to keep it up as long as you can

Ensure your rubber is in top condition

Fresh lubrication is critical

While riding your body position is critical to extracting maximum performance

Avoid putting anything in the outlet pipe as it can be dirty up there

If you go down stay there for a while to ensure everything feels OK

It's OK not to come first all the time
