TS125 hybrid project

[DR]

no probs, TMBill is the man to talk to though as he taught me a few new tricks with the 125's 

[Tim754]

I have a set of gears and the clutch basket from a RM125S trouble is you got to buy the rest of the disassembled RM125s too. Everything there except the pipe (Lost... stolen) 
Condition roughish needs a good resto  $750  Tim754

I dunno about the more HP story as a straight cut primary adds almost 2 HP to a 60HP Banshee(according to the manufacturer), TM125 even in our wildest dreams,would be lucky to see high 15HP in standard nick . Ratio is different which might work in with the box better.

Im unsure about it to the more I think about it. I dont think it is worth it for this particular project. Unless one fell into my lap...

Now Lozza, about porting the TS barrel...... tell me what you know please...

[ss2fly]

Anyone else have any ideas about porting a TS barrel to achieve more HP than a Tm as suggested by Lozza?

I want to research this before I commit to a TM barrel etc.. and find I can do some work on my spare barrel with better gains.

I realise other people have done a lot of R&D but i dont have the time and why re-invent the wheel ?

Its just for my own fun, not any financial gain. I just want to go faster on the road where the bike spends 99% of its time.

If this avenue of enquiry fails to bear fruit, i guess I will have to go the TM way.... would be a LOT more satisfying to port my own barrel and use that though!!

Come on guys, any idea?

Thanks
Andy.

The TM bolts on, porting takes time and expertise, as you've said you are not racing it.

[LWC82PE]

if you want to go faster on the road, then why not just fit a smaller rear sprocket or a larger front sprocket?

[DR]

I think it's more a case of he'd like the bike to be more snappy all over wheelstanding away from the lights 1st thru 3rd when required least I think I'm assuming correctly I'd go the way cyclegod mentioned, fit as much TM stuff as possible and you'll have more snappier HP without forsaking any reliability one of the TM and TS series main attributes was the fact they were/are super reliabilty.

[ss2fly]

Got it in one Doc, as usual... I want it to be snappier all over the rev range, particulary the top end without sacrificing the bottom end...

I will probably go the TM way as it all bolts up...

This is the current plan:

- TS125T bottom end incl gearbox, crank, electrics, clutch
- TM125 barrel, head, piston (all standard for now)
- TM125 Hop-up carb (28mm) - already have it 
- Standard pipe for now (will probably tame the engine for road use)
- RM125S primary drive setup (possibly, depending on availability)

What do you guys think about that plan?

Any other mods or ideas?

It needs to be usable and snappy and of course reliable (I ride it to work every day  )

Im 99% settled on this plan but it is open to ideas......

[DR]

the stock pipe will strangle the TS but it will be quiet. I know a guy who uses a TS pipe on his TM for practice as his neighbors spaz otherwise. It works okay but the power is down considerably according to said owner. Never tried it myself

[ss2fly]

Add to the above list a vintage iron pipe or similar ( dont give a stuff about the noise, Im a cop, whose gonna do anything about it? 

[DR]

dont give a stuff about the noise, Im a cop, whose gonna do anything about it?

yor Mama dats who!! the pipe on my TM is a TM pipe with a half decent silencer and it's not loud at all. Much better than the terrible boooooooaaaaaaaaar noise you get from the stock pipe

[ss2fly]

oooooooooooowwwwwww I want that sound!!!!

Right you lot, you all know what I need, so help me out with some bargains.... ( TMBILL....... )

The plan is in motion....

Another question....

I have a 28mm carb from the hop-up kit for the TM125, If I make a manifold and fit it to my bog stock '72 TS125T will it go any better?

Just an idea while I get parts together....

[ss2fly]

Well, I got stuck in today and made a manifold for the TS and fitted the 28mm Mikuni carb.....

It runs like a pile of crap!!!

Will run ok with the choke on but once you open it, the bike runs ok for about 10 seconds then dies. You can keep it going if you hold the throttle open at about 3/4.

Any less than that and it dies.

It doesn't matter where the needle clip is set it still does it.

I guess it is because the standard TS engine cant handle the bigger carb or is there something else I am missing.

I realise this carb will work onders on the new engine I am building, I was just mucking around till I get all the bits for the engine.....

Let me know what you all think..

Cheers

Andy.

is the carby new or used?
