When I get the piston its time to modify the crank to make clearence for the larger 58mm piston.. Need to check out the clearence for the exhaust valve too, does anyone know if this is a problem when you big bore the rm:s? Have read all info on Eric Gorr's webpage but I didn't find any info about that...
We would also do some cylinder porting for mid-top.. A V-force3 reed valve will help the bottom too..

blir det en helrivning?
Post by: ford832 on February 18, 2013, 10:59:34 PM
I think when you order those pistons you should order 2-one for the bike and one to sit on the bench to look at

Tänkte köpa mig en 125a sen också

The HGS pipe needs to bee blown out!You must ride really rocky tracks, the HGS pipe is alot thicker than a pc or fmf. I had a HGS and a PC pipe on my 01 RM125, the HGS had a much bigger increase in torque and hp. Sharp lookin Rm , I,m sure it rips.
Post by: motoxr377 on February 26, 2013, 09:38:11 PM
The bike is from 2002..
Are you sure? '02 had a tapered swingarm. Your swingarm looks like an '01. Great bikes. It's gonna rip!
Post by: Tomp on February 27, 2013, 07:02:57 PM
This is hard to say! 01 rm 125 had a straight weld on the swingarm, in 02-> the weld are bended like a C.The bike is from 2002..

01 rm had silver colour on the shock and the forks in 02-> these are in gold colour.
Svårt att se på bilderna om det är guld på gafflarna! Men längst bak på swingen ser man att din svets är rak, om du kollar in en bild på en 02a eller nyare så är den som ett u eller c.
Post by: yenko572 on February 28, 2013, 10:19:17 PM
The shock and fork is gold colored.. I have searched a lot for win identifing, but every win-decoder I have used I didnt got an answer... Vad finns det mer för kännetecken mellan -01 och -02, Tomp???

You should be able to tell what year your bike is from the engine parts.
I can't remember exactly which parts are different but when I had my 01, I know some 02 parts wont fit.
Use Alpha sports or Mr cycles part fiche's.
Post by: Tomp on March 01, 2013, 12:02:04 PM
The motor changed quite a bit in 02 from the 01.In 02 there was a new powervalve/exhaustvalve, higher comp. Stronger gearbox. and som minor changes.

For the moment I'm waiting for the cylinder(it's being overbored in Holland, NL). So I teared it down to powdercoat the frame...

How much boost you run in that beast? HP?
Post by: yenko572 on March 07, 2013, 07:08:43 PM
Around 650hp and 650ft/lbs of torq.. No boost yet, but I got a nitrous system with jets up to 250hp which is waiting to get installed... But now back to the topic, 2-STROKE MX!

The pre 04 RM's have a 105mm rod the later models a 110mm rod. They have a similar length cylinder but different cases. With the 110mm rod you will probably need a spacer plate.
Rod length RM125
99-03=102mm rod
04-10=110mm rod
This would probably not be a problem, my NEW crank(04-10) have the same stroke as my OLD one(-02). My new piston fits just the newer rod length(110mm) couse it got a higher wristpin locaction. I dont think Suzuki adjusted the case height, because newer cylinders can be used on older RM's! Biggest differences of the newer/older cylinders is most porting and exhaust valve parts...
Post by: yenko572 on March 27, 2013, 09:25:34 PM
Now it's time to make clearence for the bigger piston in the crankcase! And also check the exhaust port clearence..

Need to give you a confession 2T Institute!
I was wrong and YOU were right about the cases.. The pistons have the same wrist pin height and fits 01-08 but the newer case(04-) has a the crankshaft center lowered 8mm.. I thougt Suzuki just changed the pistons and the rods, which had been easier but they molded a new crank case instead.. 
Still dont know why wiseco stample there rm125 pistons 04-08, instead of 01-08.. The longer rod didnt fit my engine so I ordered a wiseco 102mm rod from BTO sports.. The engine is now ready and I'm looking forward to a start it and test ride..
Clearence was made in the cases and on the exhaust valve. The cylinder is ported and raised with double gaskets and the cylinder head is lathed and lowered in the cylinder. The squish area is modified and the compression is lowered a little bit.. Built for mid-top end power!
Here it is, 144cc of Suzuki Love!

i can answer this. go ahead ask me how i know? haha well i had an 04 i raced back in 07. i did the first top end and immediately had issues. very low on power( but i somehow rode it faster) and the spark plug kept coming loose. well i tore it apart and the piston was slapping the head. there was ring on the piston from it. i put it side by side and it stood a few mm's taller than the OP. it was also domed instead of flat. so that being the case the piston profile is different 04-08 vs 01-03. but bore is the same

lets go yenko its summer already.
Haha I know..
It's going forward all the time, but it's going too slow.. A little less with time is my defense, I only got a few hours in the garage for the past 2 weeks.. But after next weekend I get some more time to work on my bike.. 3 cars, 1 gokart, 1 mx-bike, 1 two year old daughter and 1 pregnant girlfriend, takes A LOT of time!
Post by: yenko572 on June 17, 2013, 04:31:24 PM
Curious to see how the RM turns out. I see lots of old GM iron in the background (guy next door has a mint 69 Buick GS400).
Yeah me too!
Yes, my blue -68 chevelle 572 and my brothers red -69 chevelle.. The Buick GS is a great car too, it is built on the same platform as the chevelle!
