Good day ladies and Gentlemen, I've decided to clean out and tune the carbies on my Honda cbr250rr mC22 as I had problems with starting and slow idle, and overall i think it would be beneficial to the performance of the engine so i was hoping anyone with experience and knowledge could help direct me and point me in the right direction, youtube videos can only get you so far at this moment I just replaced the old choke cable with a new one as it didn't stay on, so the bike is stripped an ready for action are there any kits that will be needed? and what oils/cleaners do you guys recommend I live on the Northern Beaches, in Syd btw if anyone lives nearby and wants to kill time (I'll supply beers) also, I noticed that taking apart the housing for the carbies that its cracked where you secure it to the frame any advice on what to do about this? I'm worried it will rattle around too much cheers!
Welcome Mr LoudNoises, These weird people have seal kits. http://litetek.co/Carb_Kit_Honda_CBR250RR_MC22.html and @my67xr wrote a good thread about fixing plastic. cheers Blair
Next move is to order this kit http://litetek.co/Carb_Kit_Honda_CBR250RR_MC22.html Then get yourself some of this http://2fiftycc.com/index.php?threads/cleaning-carburettors-using-threebond.3800/
alrighty, you beauty you guys are quick! I'll go ahead and order those seals and now I'm off to the store to find some threebond thanks for tips, I'll keep you guys updated
Compressed air is best to blow out jets and air passages after cleaning Also check that it has the correct main jets also .... they have numbers stamped on them .... the workshop manual should have that kind of info http://2fiftycc.com/index.php?resources/honda-cbr250r-cbr250rr-workshop-manual-mc19-mc22.66/
could you please be able to help me find the info by @my67xr on fixing plastic as I can't locate it cheers
What you might be able to do with the cracked air box mount is to cut a small piece of wire (something like .8mm or 1mm mig wire) and bend it to suit the curve of the mount, and use a soldering iron to melt it into the plastic Warm up your soldering iron and clean the solder off the tip with a wire brush or damp sponge etc. Hold the break so it's together as best you can, then place the bent piece of wire on the top, now use the soldering iron to heat it up and melt it into the plastic so it sit's a couple of mm's in below the surface. Then you can use the soldering iron to drag a little bit of the plastic across the wire to hold it in. If you have any plastic the same use that to melt over the wire, it will give it a bit more strength. Sometime's you can trim a couple of little bit's of plastic off the bottom /side's or inside the airbox to use Make sure you once you're done to clean the tip of the soldering iron as soon as you're done with a wire brush, or a damp sponge, then apply a little solder to it so it's ready to solder next time you need it You may need to give it a brush/scuff off with some 320 w/d (used dry) paper to clean the copper tip first.
You don't need an air compressor to clean the jets. Just have some carburetor or brake cleaner handy to dissolve gummed up petrol. A handy trick is to hold them up to a light source and if it looks like a circle then there won't be any debris in the jets. If the bike runs bike, the carbs won't be too dirty. For the sake of cleanliness, I would clean the exterior before you take them apart. Helps out a lot when working it them in the future.
That sounds like it would work perfectly, I'll get onto that tomorrow (after Halloween adventures) and thanks for the link to the plastic welding, great info!!
I've done a little cleaning, yet haven't done anything serious yet, I ordered the carb kit from lite tek and seeing as it will take a few days to arrive I'm going to put her all back together as I'll need her tomorrow to drive to work so once the kit arrives I'll strip her down and get stuck into the carbies- and I'll keep you all updated with photos and info so until then thanks again for all the help !
