Good place to pick up a 1997 RMX 250 Manual?
Posted March 25, 2007 - 07:00 PM
Low down is.. Motor was rebuilt a couple years ago, has been rode twice since then, clutch went out last ride, he replaced the clutch and it has sat in his basement for about a year or so.. I just hope this was not a bad investment. I want this to work but I dont want to have to pour in an absolute ton of cash to get it back running like it should.
Advice would be great. Thanks for any help. Nice to find somewhere to talk.

Back to your RMX .. the RMX is a great relatively bullet proof high performance, forgiving bike. They are a really hi spec enduro bike of which only a couple have ever been made .. the CRF450X is probably the only comparable bike in terms of spec for an enduro bike .. but back to your RMX.
There is a good Suzuki RMX manual ex Suzuki and is often seen cheap on ebay approx $10. That has all the tech info you'll ever need.
Re the rear brake. Don't assume that the rear master cylinder is shot .. could easily be air in the system somewhere .. try vigorous bleeding first. If you're Dad can get over wanting to prick your buble of enthusiasm he may even condesend to give you a hand.
If has had the work done to it that you say it shouldn't be to hard or expensive to get going. Just get the manual and start going through it.
First read the section on the carb. Make sure float level good and all clean and jetted as per the manual. Then see if you have a spark. Then check the piston and bore by peeping in through the outlet and inlet ports with reeds and exhaust removed.
When you think all that looks ok it is time to try and get it started.
Those RMX's are not the easiest to start. Really important to get the kickstarter right at the top of the compression before kicking .. if it isn't at the top it will not start! So if it is quarter way down give it a few mini kicks until it comes up against compression at the top and then choke on, tiny weeny bit of throttle and good solid kick. Once warm - no choke, 1/4 - 1/2 throttle and the same thing.
Good luck mate, you stick with it. This is how you will learn and also how you will get a real good feel when you get it running. Hey just look forward to the old man's expression when you fire it up .. and burn off any Harley in his shop

Definely do get the Suzuki OEM one that is specic to your bike though cos it will have all the correct torque settings etc.
Good luck and make sure you post when you have got it running!

I figure if I'm going to be taking the motor apart I figured I might as well do the RM top end gasket kit that adds the real power. I'll probably replace the piston rings as well, the piston should be brand new but we'll see.
RM250 (89-90) - Top End
Is that the correct set for my motor?
Thanks for the help. I'm also thinking of going ahead and getting the PWK Air Striker 38mm carb as I've read they work wonders getting the bike to idle and throttle response. Any other mods that would be reccomended for making the bike what it was meant to be while I'm taking it apart and cleaning it all up??
Thanks for all the help, love this place.

I wouldn't necessarily have the heade off at this stage but do take off the pipe, carb and reeds, then using a strong torch have a look at the bore and sides of the piston. If it all looks good and the piston looks nice and new, then get out and ride it for a good few hours before changing anything. Nice thing about those RMX is that they will go a long time between piston changes. 60hrs is not unreasitic. I change my KX25o every 30hrs.

We'll get the ignition coil on and HOPEFULLY get it running to see... *crosses fingers*
As far as the back brakes go, I have none, Hopefully the manual can tell me about the master cylinder, I think its shot, I press the pedal and it flexes as it should, but no brakes.. the back brake assembly is really loose, and I dont see an easy place to tighten it up, but I didn't pay a whole lot of attention as thats not my priority problem at the moment.
BUT I did find a grease fitting which caused joy in a couple hours of frustration. My TTR 225 did not have any of the such. But was bulletproof lol.
Main point is that we got it to fire today even if it was only for about 10 secs. Dad was shocked.. I told him I was keeping the bike anyways regardless, 99% of everything I've read on this bike is awsome. I've always wanted a 2stroke trail bike. Now I have one . Even though its not liking me much at the moment.

I read somewhere that you can go to a different spark plug with better results for trail riding, should I do this or stay with the stocker?
Any other suggestions to dekink the electrical system and clean things up nicely while waiting for my OEM Service manual to get here??
Thanks for all your help Beam
Every time I spend time with it I feel its closer to running.
EDIT: Any way the kickstart gear could be affecting this problem at all? It never tried to fire up at all when kickstarting it.
