First choice, get a new tire.
That's feasible. But I have to wait 2-3 weeks and pay about $100 for shipping for one tire. I'm thinking about buying a new set of tires with similar profile (I really liked Power Pures 120/70 + 190/55. awesome grip) and compound. Don't know what to choose. Do BR-003 racing street or Dunlop Q2 have such profile as pures have?
If that's not feasible and you need to repair the tire, remember to really REALLY take it easy on that repaired tire.
In any case, I wouldn't repair a front tire, only a rear.
Whatever you do to repair a motorcycle tire is strictly at your own risk. Read on if you like.
If the puncture is more than an inch or two from the centerline OR if it is in a groove, then the only way you can possibly repair it effectively for the remaining life of the tire is with what is called a mushroom plug from the inside.
If it's in the meat of the rubber and close to the centerline, then you can plug it with a string plug. Once it has vulcanized properly, then it should be good to go but replace it somewhat early or it will let go when the tread starts to wear thin. In other words, it's not going to last as long as an uninjured tire will last.
Let us know what you decide to do.
The puncture is about 1½ inches from the center line and not in the groove.
Basically I have the following options:
1) use a string-like plug
2) use a mushroom like patch/plug
The 1st one is the best. Am I right? Honestly I thought that it's possible to fix a tire using plain patch on the inside surface. Damn michelin's, that doesn't work on Power Pures :\
Right now there is a 2"x3" patch on the inside and still air is leaking slowly. I'm going to check the pressure drop over night and possibly I'll have 3rd variant:
3) Do nothing if the pressure drop is less then 1/2 psi / day. Just inflate it regulary.
A friend of mine suggested a good repair shop. Will ride there and see what they can do.
Thanks for the help.
