Well, as most of your know, I have been having problems with my jetting on my 300ex. Well I was doing a leak test, and I found 3 holes:ermm: in my head. Now my question is what can I do to fix it. Could I use that JB weld stuff. Or should I just get a 250x motor or 300ex motor from ebay??? Please help. I am leading the points in the series that I run and cant afford any down time.

Just buy a new head and slap it on there. How did three holes get into your head????

Agree, unless you have the money to buy a 250x engine.

well here are some pictures. I just got back from my Honda dealer and he said to just fill them with some high temp silocone until I have some time between races to get some weld on there. I think that I could find a 250x motor cheaper than a new head since the heads a 600 from the dealer and 400 from service honda.

since they are too big of a file to post here and I dont have any image programs as of now.

its not leaking, but it could turn into a problem. How much would you let those heads go for? Are they ported?

I wouldn't worry about it bro.
Iv'e seen that a lot on the 300ex's.

You dont have any water running through the head, the oil runs through a specific spot, and is unnaffected, and you have a pretty heavy steel sleeve on the inside. It's just a couple casting bubbles. I wouldn't worry one bit about it. If you think about it, there's nothing that can fail from those. Even if it went all the way through to the sleeve, you'd still be sealed tight.
