I'm trying to get to the last 2 bolts for removing the chassis from the engine. An "air flow" cover on the right side of the bike covers one of the chassis bolts. I can't remove it because the single bolt holding it in place doesn't fit any allen wrench sizes or the stock allen wrench in the bike tool kit. It's one of those starburst-shaped hex's. How do i remove this bolt? Any help is appreciated. | ||

Not sure what the 'air flow cover' is but you maybe referring to T30 Torx? There is one on the cover just behind the dipstick that is T27 as I recall. | ||

Yes, thank you! Why would they change from the T30 for a single bolt? That seems stupid. The "air flow guide" cover is the same that you guessed. It's what the manual calls it on page 2-12. | ||

 If you mean this the bolt is a T-27 | ||

Torx bits have been around since 1967. I remember my Dad grumbling about them on our car in the 1970s. 45 years later they're on just about every vehicle, so you really need to have a set of Torx bits or drivers as part of a basic vehicle tool kit. Why did they change from T30 to T27? If I had to guess, I'd say it was either torque specification or cost. T27 fasteners are rated from 16.6 to 19.8 ft-lb. T30 fasteners are rated from 22.9 to 27.6 ft-lb. Notice that there's no overlap in the torque specs. It's possible that they used the T27 because they didn't need the torque provided by T30. It's also possible that the smaller fastener is cheaper. Beancounters love that. | ||

You guys are awesome. I appreciate the quality answers I get here. | ||

If you'll check, T-27 is a 1/4-20 SAE fastener, T-30 is a 6mm metric. | ||

To the best of my knowledge, all the T27 fasteners are SAE threaded and all T30s are metric threaded. I found out the hard way when I went to borrow an airbox screw off my XB and it wouldn't thread into my 1125. Nearly all screws on the XB are T27, just like how nearly everything on the 1125 is T30. | ||

Does anybody have one of these covers? Mine is missing off my R. I need the fastener also. Don't ask me how it is missing. | ||

This plastic cover doesn't last long in the sun. This is much better... http://www.americansportbike.com/shoponline/ccp0-p rodshow/9420.html A lot of nice CF over at American Sport Bike. | ||

I hit mine with some heat-resistant rattle can paint and it has been looking good for 15k. | ||

I'm planing on doing some cf on my cr but damn expensive! | ||
| Timebandit |
Holy smokes that's an expensive little piece of bling! M0139.1AMA is a common part to the XB and costs about $12. The CF replacement from American Sport Bike costs about 9x as much. At that price the OEM replacement is looking pretty good. I can think of a lot of better ways to spend that extra $100, but that's just me being cheap. | ||

Mine is cooked. Ugliest part of the bike, next to the frame. That CF looks sweet. very sweet. |
