General Two Stroke Talk / What are the symptoms of the big end bearing worn?

« on: September 03, 2013, 12:23:33 PM »

No doubt RM's make quite a bit of engine noise compared to some of the other 250's.  I have been hearing it for years....

Sounds like you may have a clutch issue and not a low end issue.  You can get the clutch to quiet down a bit by replacing the main clutch bearing (bearing, primary driven) and spacer.

I hope this helps.

not sure about your power and speed comment...  I guess it depends on what you use the bike for. I ride mx mostly and some offroad desert/dune stuff.  I put a PC pipe and silencer on mine, with a MT reed assembly.  I agree with vetman that a flywheel weight helps with hook up on the slippery stuff.  I installed the lightest weight available and it is a simple bolt on mod.  Depending on your track 1 tooth on the rear is also a good bet....

no prob for that... yes, the needles are marked down the side.  Do you have a manual for the bike?  If not it would be good if you could get your hands on one.  There is a lot of good info there,,,,  Also MXA and Dirk Bike magazine have some good articles on the 08 Suzukis.

heading into summer here so it is already in the mid-30s, soon it will be in the mid-40s....

damn that is pretty cold..   I am at sea level here and ride in 20-40deg temps.  yep, it is the desert here.

for the 20 deg I run a 168 main, with a necH needle in the 3rd position, stock pilot.  the bikes both have vforce and PC pipe and silencer.  In the hot summer i usually drop the main down to a 165.  for your 10 deg weather you may need to richen the main to a 170 or 172.  the bikes both have a flywheel weight which helps with hook up on the hard pack and overrev...  the flywheel weight is the lightest available for the RM from steahly... 6 or 8 oz i think.  I hope this helps

General Two Stroke Talk / 150''''''''''''''''s

« on: March 31, 2013, 09:46:47 AM »

for playing offroad (and MX) you can also put in heavier springs and reduce the oil in the forks.  That will make it feel a little more plush upfront when riding rocks and roots.  I am 6'2" and 105 kg and run .46's upfront and 5.6's in the back.  I reduced the oil quantity in the fork by 10-15ml... (to 130 ml total I think).  It works for me...

General Two Stroke Talk / 150''s

« on: March 31, 2013, 07:50:46 AM »

hey, your are a kid still at 30... some of us (like yours truly) have more that 20 years on you!   yeah I know my profile says that I am a junior but that was about 40 years ago!

at 110 kg you should stick to the 250.  I have two 2008 Rms and they are great for both mx and offroad.  If you want to tame it down a little bit I have had good luck by adding a flywheel weight.  This really helps the hook up on hard pack.  Give it a try and see what you think.

General Two Stroke Talk / Woods and track tires?

« on: March 16, 2013, 08:16:55 AM »

you cant go wrong with the 952's....  our track here goes from sand to blue groove and the 952's both hook up great on the sand and dont seem to rip up so fast on the blue groove.  The Maxxis wear great on the hard pack but kinda suck in the sand.  Give the 952's a try and see what you think. Of course 110's for a 250...

Technical / What replacement clutch for my 2003 RM250?

« on: December 09, 2012, 04:59:47 AM »

well, after 37 continuous years of racing MX it is what I have experienced.  The motion pro allows for much more adjustment in the cable and probably allows for a more solid engagement; which prevents slipping, excess heat and wear, and improves clutch life.  Note, I also run quality plates and heavy springs (Barnett or EBC).

Technical / What replacement clutch for my 2003 RM250?

« on: December 08, 2012, 08:35:44 AM »

I have owned nothing but RM 250's for over 20 years (92, 96, 00, 02, 04, 06 and 08) and found that one of the best RM clutch fixes is to install an aftermarket clutch perch.  The motion pro assembly works great and really improves the overall feel of the engagement and dramatically extends the useable life of the plates.  I have the motion pro units installed on both my 08's and I am definitely a clutch abuser and ride mostly MX.....  You may want to give that a try before you invest some significant money in a Hinson system.

Technical / Bib mousse installation

« on: October 13, 2012, 09:57:37 AM »

Thanks for that Sachs, but I shudder at the thought of vice grips on my pristine rims!

I did find some good stuff on the web but there is much more involved than meets the eye...  I think I will go back to the tried and true method of small tire levers and heavy duty tubes!

I think I can get it on if I dont use the rim lock; but surely the tire will rotate with all the lube required....

Anybody out there have any experience with bib mousse installation?  I picked up a front application )pirelli) and thought I would try it.  Of course the installation instructions were missing....  I have been changing tires for decades now but couldnt get the d*mn thing on! " title="Angry" class="smiley">  it seems like the rim lock may have been the problem.  Does anyone know if you need to retain the rim lock with the bib mousse?
