Will replacing a 110 main jet with a 112 main jet on the 250 Hawk make much of a difference?

One step like that probably won't be very noticeable, especially if the jetting is already pretty close to right. Why are you thinking about the change?

Has anyone done anything to fix it?

More fender or a splash guard added on.

My '84 is exhibiting the same. Was your fix anything other than to flush the fluid a lot when replacing it ?

Thanks,

I just brought home an old Nighthawk 450. 1982 CB450SC 8,800 miles on the odometer.
She runs fine, I've been looking for a project to learn some wrenching on. She didn't cost much, lets hope there isn't too much that needs to be done.

beautiful. looks like it might could use some snow studs on the tires

MaineScoot · 03-10-2013, 05:24 AM

Hopefully by the time I get it all sorted out all that white stuff will be gone. More importantly, I hope all the sand will be off the roads. That's the real worry this time of year.

The notorious dead spot in the 450's throttle may or may not still be there.
If it is, there's a fairly easy fix for it.

Those are fun little bikes.

I'm going to be buying an 03 750 from a friend in the next few weeks. I know that the NH is pretty much a pavement bike, but the free spirit deep down inside me is... Can you do dirt or single-track on it with any degree of success? I remember seeing some pics of someone setting up their NH for off-road but I'm not sure I want to spend that much cash or time.

I took my 96 750 30 miles off road on a trail into yellowstone. It was fully loaded for two months of travel so pretty heavy. I ended up blowing both fork seals. I think you would end up having a lot of little problems like this unless you completely redid the suspension.

Dirt/gravel roads are fine. Its a bit awkward doing anything beyond that though. Kinda like wearing construction boots while running a marathon... it can be done, but its just not the right tool for the job.

Yep. Even if you've rebuilt 100 sets of forks, blowing out the suspension on a street bike is still something that sucks.

Those forks and shocks are even cheapo parts for the street and do so-so on fresh asphalt.

I already have a 84, bought another 82 in good shape and did a fly and ride lsat Sept. I had the same idea in mind, wrench without fear. If I can't put it back together, then I guess I will have spare parts for my 84. Here is a pic of my 82.
