How to re-sleeve a cylinder


jmeperu

This was done on a 400cc single but it works on twins and 4 cyl's as well. Clean your cylinder and get as much oil out as possible and freeze your new sleeve or sleeves.

Use an oven to heat to 450 deg F

push cylinder down and most of the time the sleeve or sleeves will pop up

use an oven mitt or welding glove to pull the sleeves out. if they dont pull out then gently tap them out with a large tipped punch.

remove new sleeve from freezer and drop it in.

you will still need to have a machinist face the top of the cyl and bore it to your piston, but you saved yourself a few bucks.

The hoses are topped off with a highly pigmented bright blue that will stay vibrant and not fade over time - making the Pro Circuit Standard Radiator Hose Kit the perfect way to customize the look of your bike while still increasing its performance and functionality.

      Just bought a used bike, noticed the oil was black, did a complete flush and change with filter, then rode about 3 hours worth, checked my oil sight glass and it was absolutely empty, even tried tipping the bike, and I couldn't see any in the window. I don't see any oil leaks, the exhaust is a little blue, but an entire quart in 3 hours? Any ideas what could be causing this or where the hell my oil is?

      Anyone got any tips or tricks for optimizing dead engine starts on FI electric start bikes. Specifically 2018 crf250r if you have any experience with them. I would say the theories are transferable so if you've found any tricks that help on your bike id like to know......Different fuels? Tuning changes? Larger battery? Aux battery? Larger battery cables? Seems like they are pretty hit and miss with how quickly the fire on dead engine starts
