Your not getting the point. Most of the stuff that I have found that failed has been from professional installations. Then I get to go in and clean up their mess. lol. I personally have completely destroyed 3 TB top ends, dropping valves. Not because of installation errors...Just from running the crap out of them. Then I have come across problems with parts straight from the distributor right out of the box. These are the parts I am talking about. This has gotten way out of line though, feels like I am trying to defend myself or something, like I am being accused of lying. Why would I make this up? I am here to help guys, he asked for opinions.

Ahh okay I got ya, I do remember Mike had a few pistons get through that needed valve relief changes. Now notice all the pistons have a larger relief cut out for the exhaust valve now. I actually took apart one of my motors that had the valve kissing the piston, ran fine but you could see it.

 

alright cool.

good stuff I really will look out for that and clay it to make sure I have no valve interference. Thanks for the info but after all tb stuff is probably china stuff so I could only imagine a few batches of stuff not quite to spec. But overall tb products run good and strong.

 

I like the 108 better, Turns more RPM's quicker. I like my cranks being bigger than my bore. Plus you dont have to machine the case.

The crank isnt bigger then the bore on the 108 though. 51mm crank 52mm bore.

 

Good Catch.

Uhhum, TB stuff IS NOT, made in China. Mike takes great pride in that his parts are not made there, but uses some of the same manufactuers as that of Takegawa and Kitaco.

 

ya hes right^^^
