ukjamie Posted November 22, 2011 Share Posted November 22, 2011 I've had a pinging in the engine when doing a roll-on in 4th or 5th gear. Thought it was crook gasoline at first. But I've filled up at 3 different places and it's still there. I'm the exact same. It's developed slowly over the last few thousand or so km. In 6th as well. Pull back the throttle at say 4000rpm and it will knock maybe three times by the time it gets to 6000rpm. Mainly seems to be between 5-6000rpm. I've over 22,000km on the bike and had the valves and shims checked at the 6000km service (I think, perhaps the 12,000km one). What usually causes it, and how to fix it? I'm not overly bothered by it unless it gets worse, but would be nice to get rid of it. Anyone? Ive got the same prob almost since new, and its really annoying as you cant use all the available torque in the higher gears! I thought it was just how the bike is, but if the timing can be adjusted that would be great! I guess its something we should ask Brian at Sumet to look into.

hehehoho Posted November 22, 2011 Share Posted November 22, 2011 I've really only noticed mine since maybe 20,000km on the odo. Don't know what causes it. My mate's 2004 cbr150 is about ten times worse. Would be interested in a solution though. Link to comment Share on other sites More sharing options...

hehehoho Posted November 23, 2011 Share Posted November 23, 2011 (edited) I just had to go for a quick 40 minute ride around the city. Paid attention and didn't hear it once. It's really only in the top gears if I upshift while the rpms are low, say around 4000-5000rpm and the engine is then put under load. In fact the bike sounded like a dream. No noises, no rattles, no pinging, knocking, buzzing or anything else. Like it was straight off the showroom floor, with over 22,000km on her. 2 main reasons I think, I lubed the chain with a new type of lube (the silicone lube in Homepro with rainbow on the front, 299thb for a large can) 2 days ago. And I got a new headlight bulb put in about 10 days ago. Every time Sumet take off the dash to do something the bike always sounds like it's off the showroom floor afterwards. The Pirelli tyres with 4000km on them held up and did their job a few days ago when some feckwit decided to swerve out in front of me without looking, rear tyre held firm when I think the stock would have lost it. 5,400thb well spent.

I've seen you link to it a lot though. Do you have it bookmarked or something? mine pinks at 5500 up so I changed up to 95 fuel now ok I was thinking of that after reading up a bit about it. Will fill up on Benzine 95 if I can find it and see if there's a difference. Edited November 23, 2011 by hehehoho Link to comment Share on other sites More sharing options...

nikster Posted November 23, 2011 Share Posted November 23, 2011 I thought this color scheme looks pretty hot... would love to know how that CBR250 "RR" handles, it seems to have pretty much everything changed. Full system, some sort of juice box, etc etc. The only original parts are the ones painted yellow. On sale for 230k in Chiang Mai Photo doesn't really do it justice, as it's from the phone and through the shop window. Link to comment Share on other sites More sharing options...
KRS1 Posted November 23, 2011 Share Posted November 23, 2011 (edited) Been in that shop yet nickster? Was going to pop in, but figured it might just be another overpriced fast corner clone. This is the 'KRS1' racing project bike (photo courtesy of photoshop) I got this image 'layered' in photoshop, in case anyone wants to see any other color variations...just let me know.

That fake Termi is just tacky You can dress up a pig, but it's still a pig Not to be confused with the REAL Honda CBR 250 RR: 4 cylinder, 19000 redline, 45 horsepower, 157 kg (350 lb) wet.

hehehoho Posted November 23, 2011 Share Posted November 23, 2011 230k is ridiculous for 'The Bumblebee' as it's known. Looks like a fake Termi slip-on, cheap 1,900b rear cowl, etc etc. Even still has the stock rear pegs. The Bazzaz has been released and is getting good reviews. Seems to be more effective than a change of pipe with stock ECU, as far as simple mods go. http://www.motorcycledaily.com/2011/11/md-video-review-2011-honda-cbr250r/ Link to comment Share on other sites More sharing options...

newf Posted November 24, 2011 Share Posted November 24, 2011 Update on namban exhaust. If u plan to do any track time give it a pass. No matter how much u adjust it you'll be dragging it through any quick right hand corner. API also informed me that i've probably lost torque compared to stock. It'll be replaced very soon Link to comment Share on other sites More sharing options...

In Australia the CBR 250RR sell for between A$4000 to $7000 122000 to 213000 THB The most popular 250 here for sure. Link to comment Share on other sites More sharing options...
KRS1 Posted November 24, 2011 Share Posted November 24, 2011 (edited) Anyone have a top speed after modifications? My CBR 150 hit 157 today with an oil change and new battery on stock gearing, im starting to make enough extra power to start gearing up now...so if 160 kph is all the cbr 250 has in it...going to jump pass 250cc's and into 650.

Just1Voice Posted November 25, 2011 Share Posted November 25, 2011 (edited) Ok, I'm going to throw this out and see if anyone - Brian / Sumit City perhaps - can shed any light. Was at Honda / Niyom Panich today to get new insurance on my 150. While they were doing the paperwork on that, me and wife looked at restored Steed. She loved, I didn't. Sales rep comes over, speaks minimal English. Told wife I'd rather have a 650 Ninja than the Steed. Attention goes back to the 250's, for which I plan to wait till the 2012 model comes with the tri-color paint scheme. Guy talks to wife, tell her in March that Honda is bringing out a Brand New Honda CBR 400. I asked if he was sure it was a CBR 400 or CB 400. He was ADAMANT that it's a new CBR 400. I've checked every web site I can find for the past half hour and can't find anything, and was wondering if anyone else has heard anything about this?

hehehoho Posted November 25, 2011 Share Posted November 25, 2011 I've heard rumours of it, yes. I'll wait until net year and if still no sign will probably put 30k of upgrades into the CBR250R. A relatively light and agile 400 would be good for me, the Kawa650 are just not suited to lots of city riding. And 160kph is fine when cruising the highways. Hopefully it will happen.
