2003 Suzuki RM 125 Questions & Answers
Will a 1994 125 gearbox fit a 2003 rm 125
It is highly unlikely the gearbox will mount in a 2003 frame without modifications. The crankcase part number for the '94 is 43860. The '03 number is 36890. Nine years is a wide span and many changes have taken place. Sorry.
I need help with my rm 125 1995 it has a perfect
the way you explain this, the fuel and air mix is wrong, is the spark plug wet, if it is check the carb air mix screw. remove the mix screw and use a can of air and blow it out. before doing this remove the air filter and the spark plug then spray some wd (brand name) in hole and do again with the air can. then screw back in. leave the air filter off. and put spark plug back in and start the engine you will need to adjust the screw until you can get it to start. when it does give it a few good revs and keep it running for a bit. replace the filter and start engine and you will need to adjust the air screw till the engine sounds right again.
Suzuki gp 125 1981 dont want to start
Make sure you have ignition spark and just wer yhe tip of the plug with gas. Puttting gas in the cylinder is too rich and will add to you problem. Good Luck
What kind of gear oil for 2003 rm 85
Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell.
Use TWO STROKE ENGINE OIL in the pump. If not using an automatic oil pump, then mix the gas and oil 32 to 1. That equals 4 ounces of TWO STROKE ENGINE OIL to one gallon of gas. NEVER use motor oil in the gas. Only two stroke engine oil.

Rebuilt top end twice water was leaking into oil
If it got realy hot you may of warped the head or cracked the cylinder. Do a compersition test to see how much pressure you are looseing. High would be the head witch would be easyer and cheaper to fix low you may need to replace the cylinder
Powerband
The power band is the point wheneverything is nominal and and peak performance is realized. The air/ fuel ratio , timing, rpms It's mor predominant and noticeable in a motorcycle because of handling and weight All engines have them and these "power bands are really the peak of what s also called the torque curve Band meaning sp[ecific point and duration everything is working together. a gas lawn mower engine is set up to run inside this band. Thats why it doesn't fall on its fsce on the first patch of grass.
A diesel engine has a specific rpm range it has to maintain under load to get nominal horses.. If everything is functioning at nominal, max power is put out. Surprisingly enough it can be felt in all engines if paid attention . That's all it is, no special "bands" or parts. Knowing where the power band(range is makes a big difference on any machine. On an electric motor peak torque is @ let's say 1850 rpms. go faster useless lower toyque. go slower power drops To keep the range of the power band constant. everythinhg needs to be constant, like fuel mix, spark plug condition ,air filter andcarb adjustments.. I had a bike I hate and feared the power band. I would fall into it not paying attenyion and it would litterally crawl out from under me. All it is is that narrow band of peak performance..
Why wont bike start
Probably just a fouled plug. Pull the plug and ground it on the head. Kick it over and check for spark. If you have spark just change the plug and try it.
