Are you riding a hawk also ? I can get 62 tops . How's is your low end torque with that sprocket setup . Could you give me the link to the 43t rear ?

It will pull more gear if it's hitting 75 at 8200. My Model 14 AJS, also a 250, would run in the low 80's, but it took a while to get there....ARH

Steering head bearings
Those of you who have been following this column for a while may remember what I had to say about maintaining cub-and-cone Headstock bearings. Now I have seen the actual bearings on one of the sites (could have been Calif scooter supply), and it is a little different than what I described. Their picture shows a plastic caged ball bearing set. If so, this will make re-greasing much easier. Did they do this in order to make maintenance much easier? No, they did this to make assembly easier and faster. And with it comes a problem. With cup-and-cone bearings you have to use a lot of grease in order to assemble it while keeping all of the little balls in place. So it is greased for years, with very little attention, other than making sure the stem head was tight enough to prevent front end slop. But these might be called Brilcreme bearings. (A little dab'll do ya') So they not only come with questionable quality grease, but very little of it. What reminded me of this is a post from a rider in Honduras who has to replace his stem head bearings, which are worn out. Those bearings should NEVER wear out, not if they have enough high quality marine grease in them...ARH

Manufacturers went to sealed bearings for increased service life. Wether you believe this claim or not is up to you, but testing showed that on average a sealed system suffered less bearing failure due to under lubrication and contamination.
You can argue that regular greasing of a non sealed system would be better, and i agree. The problem is that a majority of vehicle owners and many "shops" fail to do proper chassis lubrication. Things are built for the lowest common denominator. |

As far as our bikes go, they have put a thrust bearing where a taper bearing should be put, there's just to much side loading with the geometry of the frame and head-stock, and yes, its to save time and money in manufacturing. I've swapped over to taper bearings and time will tell if they are any better than OEM, as far as putting grease zerk in the head-stock, that's a ton of grease to fill the dead space!. that's like a pound of grease up there, and there's no way to be sure that its going through the cage of the bearing to be effective. I'm not knockin it tho, its better than nothing at all! |

Please note:
this is not a confirmed size for HAWK motorcycles, I have a Serpento branded bike. I know they are all very similar but other similar Chinese bikes use different sizes, unless someone has a hawk and wants to measure the OD of the stem and ID of the Frame. I did a search online and then found same on Ebay. http://www.ebay.com/itm/32005-26-26x...4AAOSwZJBX~5sA |

I'm gonna do this. Tapered bearings would make a nice upgrade, but if it ain't broke..
