I just picked up a:

04 Honda CR125, only mods are high compression piston&rings and dunlop tires. Bike only has 8 hrs on it, pretty clean bike for $1,000
I'm asking if anyone else rides or has, I will most likely have questions in the days to come since this is my first dirtbike and my first 2 stroke.

 

I can't ride a 125 but you picked up one heck of a deal. Keep that bad boy! Hey man if you want moe power u could pick you up a 500cc engine and built a super CR and be under 3G they usually around 10g.

 

keep race fuel in that bike if you want to keep it together,looks in top shape,any ?'s ask away-good to see a fellow rider ion here-phil

 

I'm running 93 octane with a 50:1 ratio of synthetic oil. The guy that had it before is really knowledgeable about bikes and he did run some 110 octane in it once, I just don't know if I can afford it for $42.50 per gallon right now...

 

I run quad motocross.

 

haha, I like the General Lee

 

I don't think I'd run 50:1 in a 125. I run 32:1 in my son's KX65. He just moved up to it from a KLX110.

 

Yep, 32:1 or even more oil than that in a 125 race bike.

As for race gas, there is a lot more to it than just higher octane. The right race gas (they are not all the same) for your bike can make a big difference in performance if you optimize your jetting for the fuel.

However, in my experience, most two strokes will run fine on pump premium. So if you on a budget and don't need the last bit of extra power, find a good gas station.

For $1,000, you did well, IMO.

I have a '02 KTM 250 Exc, 2 stroke enduro bike and single track trails are my favorite.

 

fyi-04 was the best of the last generation of cr 125's to have since the last yr for them was 07,2-50-1 is fine to run in 125's-it's not the ratio that hurts, but the ****ty oil people use in 2 strokes and poor jetting,3 -cr 125s pinged from the factory let alone add a high comp piston to the mix = melted piston,they sell sunoco 110 and vp 110 in my state for $8.50 a gallon-you do not need oxygenated unleaded fuel my friend-any more ?'s -just ask[fyi, i had full motor sponsorship from pro circuit, even with a milled head and high comp. piston,NEVER seized a bike running 50-1 with vp 110 and belray h1r]

 

I have a 2004 CRF450R It pretty much sits in my garage. I bought it thinking I was going to have time to ride but I was wrong.

 

hmm, looks like an 80

 

Well, I took it out riding today and not sure if I am going to keep it or not... I went trail riding and was really missing the bottom end torque. I love the power and handling of the bike, just not the right power range...

 

Ill sell you my 450 for 2K, you wont have a problem with power

 

If I get a 4stroke it will be fuel injection for sure

 

I really want to sell it since my dog's vet bill used up all my gun money.
