Its possible Leith that it could be "long".
I ended up buying a couple of the "long" rods that cyclegod ebayed up a while ago (god bless him) for the PE175 to keep as spares.
At $40.00 i wasn't losing any sleep over them.
These ones at $30.00 seem to have the right Part# 12161-39300

Marc i suppose everytime i walked in the shed and saw the crap lying around and looked at the 125T sitting on the stand,i was "gunna" do this and that to it.
With the RM175 sitting there as well waiting for rec-rego,my lazy arse had no motivation to work on any of them.
Luckily my mate picked up his kids XR100 out of my shed yesterday,so there is 1 less bike to look at.

cheers..mario

I was going through my "junk" in the shed and decided to pull down the the rest of the RM125B engine that came in this $50.00 alphabet beast from early this year.

The top end had water sitting in it for god knows how long and i pulled the top end off when i got it home.
Just pulled the bottom end apart and luckily no water in the trans.
All in very good knick,main bearings rusty,big end of the rod moves fine but small end rusted (new rod kit i'd say)Cases good too.
I went back to the barrel and noticed this... Boyesen reeds?? Dual stage??
Or just home made jobbies?

Yes Boyesens

[DR]

hunt around and you can pick up replacements for about $20 Mario..#600

Mario .... looks like it might have a C front end along  with tank , triple are right .  Fruit Salad can - are you telling us something   

[monaro308]

Thanks boys....i just checked a PE175D engine i have in bits and the barrel has the same reeds,possibly thinner than the B ones.
Just checking as the ones above looked home made but most likely weathered.
I think its a PE-C front end,definetly an N tank,I'm sure its an A frame,have to recheck the # and a B engine....hense alphabet bike
Doc got the PP brackets,the RM125T got the throttle after i raided the magura to go on my RM175EF.
Just stripping things as i was worried about water damage to the cranks and trans that were sitting  in those engines before i got them.
PE175C,RM125B done... on to the PE175D now.
Then i'll pull me finger out and get the RM125T engine apart when the rod kit arrives.
Fruit salad...lol more like fruit loops with some of the crap sitting around......but i bet you lot have more 

[LWC82PE]

I would have said they were Boyesen #602

[oldfart]

And it's a home brand at that 

[DR]

yup, onya Leith..602 is the duel stage RM125 from 1900-1978 sorry my memory oops..600 are 185ER..close

Mario think I need only 2 more to complete the full set but my memory is failing obviously..I do know for sure that I only have 1 headlight though so it could be no more than 4  

[LWC82PE]

602 is what i use in TS185/250 which is same as early RM250. I checked the Boyesen catalogue and 600 is for 79-80 RM125. On a side note ive got a 6 petal DG reed block for the TS185 to try out

[monaro308]

Doc i think you had 2 already as you mentioned 1 side was cable tied and got my 2....but like you said the memory plays funny buggers and i'm forgetting what i have.
Was there any way of IDing the reeds once they were out of the pack like a part# printed or etched on the petals?
6 petals Leith  how you gonna keep the front end down!

[LWC82PE]

No part numbers printed on the reeds, but through process of elimination it wouldnt be hard for us to work out.

[monaro308]

I Had time to get stuck into the 100/125T engine.

Snuck the 125 crank into work last night and pressed the pin out.....nice mess

A while ago there was debate about case differences between the 100X and 125 NT variety and crank diameters...ie 100 has smaller webbing to 125 and case volume.
I sort of sorted that out a few months ago in another thread.
This time i can confirm.....RM100X crank is the same diameter as the RM125T crank but the crank pin is at a different point...obviously.
Shame as this 100x crank is in VGC,nice rod clearance and .25 piston.
Barrel even has boyesens.....coming out of my arse at the moment,thats 3 engines with them!

Another thing i can confirm is the cases are exactly the same and the only difference i can find is the engine # stamping. 100x - top 125T - bottom


Even this # is identical (whatever it is )

There you go,one for the ozvmx reference material.
Waiting on the rod kit to arrive and then to buy new gaskets and seals and slap it together.
cheers...Mario

I still have an RM100T engine awaiting a home Mario. I was going to slip it into a TS100ER sleeper but there was a little too much frame interference around the gear lever area. Just means I'd have to mod the frame or make a linkage setup but this I didn't want as the TS has all parts and was/is to be re-assembled at a later date including a nos RM100B/C cylinder that incidently slips straight on If all the bikes wearn't so difficult to get and I had space to move around them I'd be more inclined to get into these projects but at the moment with work and stuff it's just too much trouble..roll on winter 2011

[monaro308]

Would any of you kind hearted Suzuki boys have a scan of the RM125T service manual (i assume N to be similar) or even a pic of the specs page refering to the crank info.
The owners manual doesn't specify crank specs ie crank web width,rod clearances.
I have a PE clymer manual and an RM 81- 88 clymer which gives the specs.

Much appreciated 

cheers..mario
