CR125 Wide Open?


Recommended Posts

When ever i get in a straight and pin it, i pin it wot for 6 seconds and go to half throttle... imo 2 strokes(especially 125s) arnt ment to go wot for long periouds of time, their ment for track, your not gonna be going wot 100% of the time, always shifting and in different rpms etc... But it wont hurt to do it here and there just go fromfull throttle to half. Is the new top end broken in? I would jet the bike ritcher, especially for a 125. I would use a castor/synthetic blend, castor leaves a nice film of oil on cylinder wall and lubes better when under more load/hotter conditions and dosent burn off as easy as a pure synthetic. My 2 cents

if your going flat out, getting it into high RPM, them letting off the throttle, then your asking to seize it, two strokes rely on the fuel for lubrication, if you have the throttle closed at high RPM then engine is spun up, and getting no where near enough lube, if you have a long strait go up a main jet size and hold it wide open allt he way along the strait.

f your asking if you can cruise along the road at WOT for a few miles, then no, you'r gonna have the rod poking through the front of the engine in no time doing that.

yes, the top end is broken in. Okay, well i was just wondering cause my friends with CRF150f's love flying down the road wide open and they pull away from me cause i dont wanna blow my top end. I do the same thing, go from full throttle to half. The 4 stroke boys tho, when its in trail or track thats when i ride hard haha. They love trying to catch me.

Track is a bit different since it varries the loads vs flat out on a straight road

As long as you use good lubricants for premix (i only use amsoil) and the bike is jetted properly you will be fine.

Well i think with lots of 2 strokes you have to stay on the pipe, and i can keep up with him. but i HATE pinning my bike on straights.

Just remember to roll on and off the throttle or use the clutch but i try not to use my clutch not even to shift 125s are not putter aroud bikes they like 6th gear and on that pipe

Yeah, but ive only been riding 2 stroke 125s for a year and upgraded from a 125 4 stroke.. im already bored with the power haha but yes, i do roll on and off when im flying down the road I really HATE pinning it down the road.

You can't be too bored of the power since it doesn't sound like you actually ride the bike to it's potential. It isn't made to run down the road against kids 4t trail bikes, it is made to be out on the track. And, with the right mods, out on the trails. I don't think anyone really gets 'bored' of a 125 2t unless they are just too physically big for it, or a very competitive racer and looking to upgrade and grow through the ranks.

Yah haha bored of it and dont wanna pin it down the road.. I will pin it in trails or in gravel pits. Never been to a track yet haha.

MXkid was being sarcastic...

If youve only been riding it for a year and your pinning it in the trails you must be a quick learner... or the trails arent very challenging (unless your talking about pinning it for short periods of time). Ive been riding 125s for 13 years and I still cant use all of its power, track or trails! Im a top 5 B class rider on a consistant basis too! If a 125 bores you, your gonna be bored on anything you ride! 125s are simply the most fun bikes to ride... ever IMHO!
