pk135 Fabrizi.

Went to Lincoln today to get my bike tuned on the dyno for $100 set up fee and $70 per hour. After my carb fucked out and I cleaned it the bike was on the dyno and reading 16.5 horsepower at the rear wheel, not bad considering it still had to be tuned, all was looking good a nice torque curve a small dip in it, but hey that's why I have brought it here to get rid of that. All is going good then.... SEIZE, wicked. The bike nipped up and was leaking oil from the fly wheel. So I took it home and I pulled it apart and the rings weren't even stuffed (that was until I snapped one) its a very slight seize, It did it because the barrel was too tight so I am gonna clean it up with some wet and dry and hone it. And then take to the piston with a fine file (hopefully fast135 can do this since hes done it a few times before and i don't wanna fuck the piston).
So no biggie just hone, clean up and new rings. The carb settings are good he told me to change it by bringing the needle up a bit by dropping the cir-clip down a notch, and I have been told to change my spark plug from a b8hs to a b10hs.

All in all I am happy I know an rs125 puts out 46+ horsepower but this is a 1960s air cooled cast iron scooter... wait an rs125 motor is about as big as mine and has three times the horsepower hmmmm....

Any who there is a little video (512kb) of me seizing and a picture of the bike on the dyno.

Take it to an engine re conditioner and get it accurately sized and re machined/honed.
Yes filing may have worked in the past, but fuck that's rough engineering

yeah, its going to an engineer to get honed. the piston has a slight smear of cast iron on the exhaust side of the skirt. Its real easy to clean it off with a fine file. there is no need to buy a new piston. Yes filing has worked in the past and STILL works.

I've cleaned up many a two smoker piston with a file. Judiciously. I don't think there is a better way.Properly done the result is as good as you'd get with a toolroom lathe, with the advantage that you don't risk meddling with the other side of the piston as you would spinning it in a lathe.

A toolmaker would weep

I am gonna get an engine reconditioner to hone the barrel but I need to clean it up first other wise the hone just skips over the alloy. I have taken my barrel to a dude who is gonna polish the ports or some shit make it flow better then hone it and throw some new rings on it, do a few more kms then back to the dyno and give all you bikers the learn....

WINJA you havent meet my mother have you she would give a thou the learn.
