decisions decisions...what to do?

[monaro308]

I've have come to decide what to do with my RM125T.
I've mentioned that this bike has a 100 crank and top end after the previous owner/s seized the big-end and decided to use the 100 parts to keep it going (must have had a spare 100 engine and used the above parts)

Trying to work out if its worth rebuilding the crank with a new rod kit and putting it back together and selling as a 125.
The bike came with all the original 125 top end and blown crank (crank is fine).
Sell it as it is with all the parts and let someone else rebuild/enjoy the bike....i never ride it.

What do they charge these days for a crank rebuild??

The bike is quite nice,rear shocks (damn hard to find) is in excellent condition and has new oil and regassed,shafts spotless.
Forks,the same only the lower legs look dirty from the crappy varnish.
Seat cover A1,front and rear guards and side covers were painted before i got it,tank isn't painted but very good.
It has a N model swingarm and brand new rear tyre,90% front M12,new sprockets and chain.
The rear axle took me ages to find (nuts on both sides).
The rest of the bike is nice too....runs ,stops,
Not sure what the front plate is off...part no 94911-14100 (maybe a cut down 125X plate)

What do you (Suzuki boys)all reckon???
Fix it up as a 125 again.....more cost to me
Sell it as it is and let someone else fix it?
I could wreck it out and maybe make the same money as it is (dont care about the money)
I'd like to keep the bike,but i don't ride it,it will give me the extra room,etc
HELP!!!!!!!!!!!

What's a 'blown crank' ? Big end or something with the webs? Anything more than $50 to rebuild a single cyl crank is a rip off. A rod lit could be had for $100 or so on ebay.

[LWC82PE]

Yeah i had 2 cranks done by www.iwt.com.au and both times they were about $30

Decent looking bike, I would return it to 125, its worth SFA as a 100.

Bit of a polish up and some decals and it ends up VMX prime rib.

Hi Marc. Is it in Australia?. I could do with a project like that .

[oldfart]

Hold onto it if you can, as they are becoming sort after ( Rm 125 T ). I'm in the throws of rebuilding mine from scratch and it's in the same condition as yours .....rebuild budget is around $1000-00 we will see 
I'm sure someone will help out with a bottom end ( 125 ) 

[monaro308]

Lozza...yeah just a seized big end,so a rod kit and put it all together.
I could do it at work as i don't have a press at home but work is getting a bit funny with doing "home stuff "
If thats the going rate,thats pretty good.
Thats a sweet looking 125 Marc,i remember the last time you showed those pics and yes you are right as a 125 it is worth more,plus i like the look of the T models.
As a 125 i would probably/most likely end up riding it anyway.

Oldfart....post pics of your build...for motivation

Ok decision done......i'm keeping it and will clean it up and get it back to a 125.
cheers...mario

Oops, I thought it was Marc's bike!

Oops, I thought it was Marc's bike!

It was built for the owner of Chaparral Honda/Suzuki / every thing in the USA. Lot of good bits, but good make over of Monaros bike would see it looking similar.... the bones are there just needs some lovin. 

[monaro308]

Where are you Suzuki boys buying your rod kits from?
Just checking for my 125T motor and know that the rod does about 48 models
There are NOS kits around that do DS/TM,RM etc but the difference seems to be the crank pin from what i can see.
Any recommendations from here or the US?
Just doing the sums at the moment.
Thanks...Mario

I would say that its just the length that is the difference. TS, TC, TM, DS etc probably use a different length rod

Ebay should be the cheapest

[monaro308]

Thanks leith for that info.
I think the rods are all the same but the crank pins are different (if thats what you were refering to)
I found this kit and the seller states that they are made OEM for Suzuki.
Can anyone ID the rod to be a Suzuki item?
At $30.00 US for the kit (just waiting on a shipping cost)

[LWC82PE]

Whats the ebay link to that kit? It might be Long kit which is made in Japan.

[Marc.com]

So there you go not crazy expensive to rebuild and suddenly the RM125 is worth gold.

[oldfart]

Get him to post a pic of opposite side of rod to see if it has the  S  on it.    Is it from ole mate in Thailand
