- The cylinder is back from the repair shop. We install the repaired cylinder, new Wiseco Pro Lite piston and new head. The bike starts, but it's making a sound that makes us uneasy.

Great video!
Wow the way you were all organized and clean assembling the cylinder back together it was hard to believe w all those nice expensive shiny parts going back into a bike it was that caked w mud......I've watch alot of videos on here w rebuilds and any competent builder Always cleans the bike before doing any wrenching.....I've seen a pinch of course sand totally wipe an engine out within minutes......I couldn't watch the rest of video after seeing that bike!!!!!!....lol......so didn't see if you changed out that air filter or.not but I hope you did since tht dirty filter will quickly allow fine particles past and ruin your new shiny wiseco..............I think that piston kit is worth more.than the bike!!!!!...lol........I dunno, maybe this is how people muster up views by doing shit like this!!!!...lol
Just a normal person doing a rebuild lol.. other than doing gram off restorations whenever doing a top end I’ve never taken the engine out and cleaned it. Pretty pointless other than looks
Should have checked the bearing play before the new jug. Just for peace of mind.
I would’ve never torn down a bike if it was that dirty. But if you didn’t mess nothing up then I suppose you got lucky😂
Bro I cringed when I saw that jug going back on 😳
Hi , its piston slap I'm sure , it happens on forged pistons and you will find that the noise gets less as you ride the bike and get it hot. I had the exact same problem after my was jug re -lined, I now only run cast piston as I hate the sound. Double check your piston to cylinder clearance if you have the tools. it should be 0.05mm between the two for a cast piston and slightly larger for forged about 0.06mm to 0.07mm for room to expand. Correct me if I'm wrong and you've sorted your problem.
hope that helps
Thanks for the info. We’ve been waiting for the weather to warm up before we ride it any. I’ll report back once we put a few miles on it.
@@TheRacingNelsons Ah right , yeah let me know how it goes! , once its got heat in it you should find the noise fades. That piston slap isn't a very pleasant sound I know. If it doesn't fade when hot then its time to check piston to wall clearance. The ring having to much gap at the start might be an indication the cylinder hasn't been
re-plated correctly and the jug is out of spec. This exact thing happened to me and they re -lined it for free. Hope this helps a little !
Did you ever end up figuring out what the noise was, my bike has the same noise.
clean the bike when you do surgery please
Dont let me wrong but quick wash of a bike its a good think now and then
good video man, did u get anywhere with it?
Yep, pretty sure it’s the forged piston. I’m editing a new video now.
Look forward to watching it
