Question about 2003 Honda CB 250 Nighthawk

1 Answer

Wondering if 93 octane in a 250 honda nighthawk is the reason it keeps fouling the plugs. The bikes are being used for msf brc classes and they dont get ridin hard. top speeds are about 12 to 15 mph. Frequent stop and go, for about 10 15 mins. at a time? Could that octane be the cause there running to rich?

Have a Suzuki savage LS 650. Having problems starting all I hear is one click when trying to start. Bike does start with popping the clutch. Problem started after I jump started the bike a week ago? Bike...

I toook the msf course last august. My only reasons were that i was tired of riding on the bike of bikes with guys and decided to flex my independence. i however dropped the bike in the msf course but i still passed and got my endorsement. i bought a ninja 250 and rode it under various conditions here in NYC. (just use your imagination). i didnt get a lot of mileage in but i learned some valualbe lesson, so, i was going to keep the 250 and the sv but i got an offer for the 250 and i am going to sell it. i like the smaller cc bike because it is easy to handle and forgiving yet it is still a motorcycle. the sv650 is that venture into a more serious bike and if you are not heavy handed on the throttle and can handle the shifting the bike should be fun and a learning experience. the main reason i bought is the comfort for longer rides and touring. the 250 just wasnt made for that. i am planning to do more rides to vermont, new england and the delaware/maryland area. i know the torque and horsepower are totally different from the 250 but i can appreciate the difference. it also have benefited from chatting in the forums. i almost bought a zzr but realized i was way out of my league! OK...I think I made a point :thumbsup:

figure I'll throw in my 2cents from my own experience. I picked up the SV650 as my first bike last year. I had not been on a bike thats not pedal powered before, however I used to live on my bicycle, did lengthy tours on it, commute on it, modded it, did all the work on it myself. My point being I knew I loved the feeling of being on two wheels, riding. And I was very experienced with being a bike in traffic. so that was going to be a non-issue. I picked up a book called "How to Ride a Motorcycle" by Pat Hahn. In there he says In the authors opinion Suzuki can claim to offer the best all around beginner bike in the SV650. Light, nimble, quick, adaptable, fun, and cheap, its easy to ride - which means you'll learn very quickly - yet versatile enough to keep you entertained for a while. Great I thought, but he also stressed the importance of the MSF beginners course. So I got myself into a class and practiced in my apartment complex on my sv while I waited. When I took the class I was amazed at how much I learned so quickly on the nighthawk 250. I left feeling very confident having received a perfect score on my test (in fact the instructor said that if all his students had my kind of background on bicycles he'd have a class full of perfect scores, pretty cool I thought) After that riding the SV became easier and my learning has continued full boar.

The point of this rambling is that the SV was an acceptable beginners bike for me and apparently for many. But if I was forced to spend a year on the nighthawk 250, I'd surely learn more faster.

performance chips for BMW.

1991 CB 250 Nighthawk: whats the top speed for a 1991 honda nighthawk 250...

I have had my 2008 Nighthawk 250 up to 70mph with some left over. I just got it so I haven't really run it full throttle yet ( 75 miles on the OD ) I weight 300 lbs. I would guess 80 on a flat road. I felt comfy at 70 but this is my 5th bike. I bought this one for the gas mileage and 1 yr. warranty. I will try actual top speed on the Interstate in about 1000 miles. Hope this helps. I like the bike. Chris

My yz wont start, changed spark plug it ran for 1/2hr then died

Couple things- 1. If the plug was dirty after 1/2 hour you have either the wrong heat range plug(too cold) or 2. a fuel/carb issue. Buy a hotter NGK plug, ask for help the numbers don't always make sense. Use only full synthetic 2 stroke (I always liked bel-ray) and fresh 93 octane fuel. When you find a plug that works good buy a case of them, 2 stokes will foul plugs period. And some advice with your solution, never head into the woods without a spare plug, they will foul at the absolute worst time.
