Doing that will take a little off the bottom and wake up the mid and top end.

honda would have used straight plug hadent it been for clearance issues. what kind of difference it would make is what im wondering

. ive looked at alot of race heads for various machines and all use straight plug

I'm somewhat curious about it too. One of my 500 motors has a straight plug, the other is angled.

The angled plugs are for hillclimbing

The regular straight plugs would foul out because of riding on an incline

Angle plugs are better IF you index them properly. The open end of the electrode should face the top of the piston. This is done to "unshroud" the spark and leave it more open facing the fuel/air charge to help achieve complete burn. If you have a properly tuned motor and you take the head off you will see carbon tracks showing you flame front travel and this will help you understand the theory.
If you want to try it, take a sharpie and put a mark on the "socket" area of the plug in the same area as the electrode and preferably use a fresh crush washer. Then just SAFELY tighten the plug till the mark on the plug corresponds properly to the top of the piston.
Then report back here and tell me how it made a HUGE noticeable difference and made you fast enough to smoke "The Stoffers"...

The only thing I'm sure of is you'd need to index yours at least two or three times!

Its a pretty minimal difference, and its much more difficult to drill and tap at an angle.

My 500 has an angled plug and there isnt any clearance issue...

This machine has a straight plug and an angled plug. Look what happens when the guy uses the straight plug.
