By the sound of that "slap" sound.
Similar to the sound I had on a fresh rebore I had a few years ago. I had 3 thou clearance...each f@@king side of the piston!
Piston to bore clearance
Put it all back together Adam, runs fine, little bit noisy at low tick over speed, but runs fine. Will look to doing a proper rebuild next winter.Adam_Winstone wrote:This thread was never about what clearance you would start with on a rebore, rather, it was about how big is too big on a used bore.
TS1-200, how are you getting on?

Some people laugh when you tell them that but i was told they are the best "standard type" on the market by the guy who did mine.Cheap as well,cant see why you would spend more unless you had something very revvy or had massive exhaust port.hatch wrote:Af Rayspeed Mahle pistons are the best ive found / always use now, standard type and there beefed up to stop cracking on the skirts , with 200 careful miles running in on flat roads you can do these at 2-2.5 thou , with fully syn at 2% , never had any problems
Yes there great , best you can buy and why people use more than 2% in standard bikes ill never know

This was done years ago by Malc Anderson at MSC,he just had some feelers down each side of the piston to show that what a perfect job the other company did.He wasnt being exact,just showing it was shite and needed doing again and they did it while i waited and was perfect.Obviously if being exact,i would use some verniers.Grumpy225 wrote:soosh wrote:By the sound of that "slap" sound.
