Ok will do I'm guessing leisure trail is the best place to go?..... Also I think what happened was the guy that had it before me did not run in the last piston.... Sounds like it has piston slack..

Ok... What would be the main cause? ...I suspect the last owner replaced piston with same size but not rebore.....

Ok so I done a compression test..... It's reading 95psi.... That's low right? Plug was a good colour tho... :-/

Thanks for the info guys.. I am going to do a compression test tomorrow and I'm going to check jet, and plug

Kinda hoping my crm was going to be like this lol https://youtu.be/-UCpzAJ_ORs

Just sticking with the oils you have recommended


Thanks

could it be that the flap is stuck on the exhaust port? although the power valve is working.... im just thinking the powervalve flap might be stuck? also i will do a compression test soon. and fallenmikethebike its not in Gozo... but very close hehe, https://youtu.be/z51cA0cLKgE

Morning all! i was running 13/45 teeth in that vid... and now im running 13/39 teeth... thats why i am scratching my head.. because in the vid its got 13/45 which should give me good acceleration?.... but there is just no power on take off?... and the air filter/sponge is not that old and crusty its...

How would I check that? Does not say on bottle... :-/

Thanks for reply.. I took the cover over the power valve and revved it up and it's working fine.... Works just like the one on the YouTube vid... I don't get it.. Confused.... What else could it be.. I will do a vid also

Thanks

Hi,

I have lots of 2 stroke castrol oil kicking about can I use it? 100% and semi-synthetic. (Castrol R 2T? Red Bottle)

Thanks Darryl

Also I took off front pipe to look at power valve flap... And it won't move..... Surely it's meant to..

Haha Thanks bud! My front wheel is certainly not going to lift of the ground very easy lol not unless I Rev it right up and dump the clutch! I could wheelie my dt125r easier than Crm..... I'm sure something is not right... It's just good for top speed and crap on take off

Hello! just bought my first crm 250 (mk2)... i do love it but im sure its ment to be faster on take off... its like riding a Dt125r? ... it has had a top end rebuild.. so im guessing its something to do with powervalve... only thinking this after reading alot on the forum.. what are your thoughts pe...

Hello! im also new to the forum! i am from the uk but moved to malta (europe) last year... and wanted a nice 250 2stroke.. had stubbled across the crm 250 mk2... really enjoying it... however not impressed with power... so going to talk more about that on other pages..
