    Howdy, Unfortunately the big end bearings for the MC22 engines are no longer being made by Honda (I found out when I went to order). Does any one know of any other good quality suppliers/ brands that can supply them? Does any one know where I might be able to purchase some from? Thanks

    Hi guys, not sure if this is a good idea but the only thing that could go wrong is a dead battery so do this at your own risk. I recently decided that the 250rr is probably going to be my one and only bike for a while, until I decide that ringing out a 250 isn’t fun anymore, and I use it for...

    Hey. I would like to introduce myself I'm some guy travelling on mc22 and have been getting some problems with my bike lately and I thought i would ask here instead of paying a mechanic to maybe fix my problem. So I have been getting some ticking sounds from my engine. It's a 1991 model and has...

    Hi all, just started my 1990 mc22 after doing valve clearance, hasn’t been started in over 2 years, been doing lots of work to it slowly. Went over the clearance so many times because it was my first and didn’t want to mess it up, started heaps easy but they are way louder now. All were very...

    Hey all 👍🏻 New member, so I'll keep it short, looking for anyone who has successfully installed any type of fuel gauge system to an mc22. Had a browse but couldn't find a post where someone had pulled this off or even attempted it. Love it if the "just open the cap and look" crew could refrain...

    Hi all, just wanted to ask how to mount the rear fairing that surrounds the tail light to the rear side fairings, my old tail fairing was cracked on both sides and now my new one has also cracked. I've used a threaded clip with a bolt, now I've just put a nut and bolt in, but this seems wrong as...

    I have a 1995 CBR250RR(R) and when I apply full throttle under load (in gear) after around 12000 rpm the power becomes jerky with pauses of stagnation at around 2000rpm intervals (12000, 14000, 16000 etc) all the way up to the top of the RPM (18-20). I removed and cleaned the carbys (fuel bowls...

    Hi all, I own a CBR250RR(MC22) and Decided to give the carbies a clean. I removed my Throttle Push/Pull cables, cleaned the carbs and re-seated the push/pull cables the way I found them. Now I have 0mm of free play when I twist the throttle. I've tried: Adjusting the cable tension at the...

    Hey guys, have an issue with my mc22. It starts fine and revs a little and rides, but won’t pull past 12000rpm, if you ease throttle a little back it does pull to 14000 rpm but crackles. The mechanic said I would need new set of carb for the bike, he has taken them apart cleaned them and put it...

    Hey everyone, the short version of my story is I live in the US and bought an imported MC22 (1990) about a year or two ago and after it started having some issues, I took it in to a shop, and it's basically all done but they've discovered a hole that's worn in one of the bodies of the carbs, and...

    Hi, I am hoping someone will be able to help me out with the charging system on my bike. I purchased the bike and rode it home. Later in the night we went to turn it on again and it struggled to crank over. We then push started it but it died when the bike came to a stand still. Purchased a...

I read a site ages ago, but cant find it again. Something like mc19 block - mc22 crank, pistons, mc22...

    I recently got into a crash which led to my front end being screwed - forks bent backwards, front axle bent, and forking pissed everywhere. So I was wondering what front end I can replace it with :/ In my area it is very hard to find a front end for an MC22. I have found a MC17 front end but...

    My bike is a 1988 CBR250r So basicly I've done everything to check why my cbr isnt starting and i checked the wire outlets for the fuel pump and they are good so that leaves me with the conclusion that the fuel pump's days are over. Ive had a look around for a new fuel pump and apparently they...

    Hey guys, this is my first post here. i thought i might as well sign up to learn more about my recently acquired cbr250rr. Anyhow, since I got it, it was running fine, however after getting home one weekend away I hopped on my bike only to find that it was sounding like a lawnmower (modern...
