Hello fellow bike enthusiasts! I'm a squeaky clean new member to this lovely website, so I thought I would say hello I'm from Manly, Sydney and have recently purchased a Honda CBR 250 rr !! It's a second hand bike a needs a little bit of tlc, which I was hoping other, more experienced members could help point me in the right direction. Really looking forward to making new friends, increasing my knowledge of bikes and getting my hands dirty on DIY mechanic projects right now my CBR250rr is having a little trouble starting first time (without having to rely on the choke) any suggestions as to why this is? and what could fix it? here's a picture of my baby
Nice, that quite a tidy looking MC22, if your looking for spares you cant go past @XCite Bikes , Omar is based in Sydney ( Liverpool area) and his website is www.xcitebikes.com.au With regards to starting, the correct way to fire them up is full choke no throttle and hit the button, once it starts let it settle then push the choke in. They are an awesome bike, great pick up !!! Chris
Hey mate, I am in sydney and your bike looks very similar to mine haha, I know these bikes insanely well. If you would like me to take a look let me know!
Howdy! If I'm lucky, I can milk the throttle while hitting the starter button and the bike will start. My luck is about 30%. Kiffstas method works the other 70% if the 30% didn't work
thanks for all the feed back everyone! woo so pleased that people actually commented on my post (sorry for late reply, bit busy atm) so using the choke to start every time is okay? I do use full choke to start, then ease off once its settled. But I had this niggling thought that it would be bad for the engine/i shouldn't have to use it??
is there anything you could tell me about these bikes? I ******* love riding it-but I feel as if there is a secret method to riding the cbr MC22 that I don't know. As in RPM gear change/ necessary warm up / should i wait for a warm engine before hitting max RPM (although hard, it is fun to do in morning traffic occasionally ) any tips or information is welcomed!
Secret to riding it, uhhh umm this is going to sound so stupid but I feel like the bike rides me, not the other way around. If you feel as if the bike is saying "this sucks don't rev me up to 18k rpm because I am cold" then don't. If your unsure when to change gears etc and your curious as to "whats the go with warm up" etc I can tell you this, the "warmer" the engine (up to 2 3rds of the way on the temp sensor) the longer it will last when your thrashing it. Like if you thrash it at colder temperatures the wear rate will increase but so should the performance theoretically. The bike its self sort of tells you when to change gears, if its not giving you any more power out of the gear shift up, the bike doesn't have a slipper clutch and has a tendency to compression lock when down gearing so learn the art of blipping the throttle as you down gear and brake, the sooner you practise these the better. It sounds like to me as if you are unhappy, this shouldn't be the case. I don't know if your interested in doing any mechanical work your self but if you are, read the work shop manual a handful of times. Every time I read it I pick up on things I have missed each time. In terms of maintenance the first thing id be checking is if the fork tubes are bent, putting in new fork oil and fork seals. If I recall correctly you have rossoII's on it? these are good tyres and you should finish the life of them, but be warned they can be a little temperamental in the cold or wet. Clean the chain and lube it well, set the slack to 20mm movement up and down from the halfway mark between the front and rear sprocket. I have found the rear "alignment markers" to actually be exceptionally accurate on the mc22 or at least on mine. Changing the wheel bearings is a good move. The electrical's will be the first thing to fail you I am sure! one way or another... Get familiar with the bikes electric system, I made a coloured wiring diagram that may help should you face any of the common issues. Now I am the biggest hypocrite in the WORLD saying this... But the BEST advice ANYONE could give in terms of power is follow the service manual to a T and don't fk with the intake or jetting of the bike. Keep it stock, clean the carbs and use liteteks seal kit to re seal everything with new gaskets etc. These days I use castroll GTX 20-50W oil because atmospheric temperature doesn't drop below 0 here in aus, but being that its not fully synthetic you have to change the oil twice as often but because its 30$ for 5ltrs it works out allot better in my opinion. Listen to NGK's advice, they say iridium plugs are better than standard and last longer, I agree. The rear shock is the hard part, pretty much guaranteed yours is blown, what you can do is ROUGHLY the following, find a 300mm eye to eye shock with a stroke of 50mm and a spring rate of 10kg/mm then modify the celvis to be 20mm shorter, thats what I did anyway and it works wonders. The cheap solution for the front springs is to put ninja250/ninja300 fork springs in insread of the stock mc22 springs. The ninja250 ex250 fork springs are 0.65kg/mm straight rate springs and that is a good suspension set up. In terms of brakes if your sticking with the stock calipers etc id honestly just install some braided lines on the front and change the pads and put in some new dot4 fluid, not much to it really. I found that cleaning the carbs with threebond is great, then running some threebond through the engine to remove some carbon build up will get you some power back. I put in some ebc clutch plates and springs for the clutch, thats a good idea and worked well for me. The following are just my personal preferences but everyone's taste varies: I like the stock gearing of the bike 17 teeth front 52 teeth rear. I like the hiflo-flitro air filter and oil filter. I like bridgestone rs10 tyes at 30psi rear, 30psi front. I like ngk 0.9mm gapped cr9ehix-9 spark plugs I like ebc brake pads I like lithium batteries I like forseti reg/rec I like dynatek 3ohm coils I like 4 short velocity stacks with 108 main jets I like straight through mufflers I like stock grips and levers I like stock rear sets I like see through wind shield I like 91 or 95 RON petrol without ethanol I like ceramic hybrid wheel bearings Umm to give some backround on my advice and how valid it is, I have owned my mc22 for about 2 years and am on my full license and have no current plans to replace my bike, I have never had a crash or dropped my bike and its my only form of transport and use it daily. HOWEVER I have never been on the track and the only EVIDENCE of my bikes power was a dyno reading of 40hp however the fuel to air was way out and the oil was well over filled when this dyno was done but I was in a learning phase and that was long ago. If your thinking about doing something stupid odds are I have done it and somehow been lucky up to this point? Anyway the forum members around here are the smartest and the best, I'm more of one of the stupid ones tbh. If anything SERIOUS comes up @kiffsta @GreyImport @maelstrom have always bluntly pointed my in the right direction, at the end of the day motorcycles can be fun but are dangerous in the hands of the young and ignorant. Sorry didn't mean to turn this into a book, good luck!!!
