Alright one last question gents. Down to the new carbs jetting. I've got #220 main and #50 pilots in my VM34 Mikuni carbs. I need to the conversion for these 33mm Keihin PWKs (that are currently running #152 mains and #50 pilots). She ran like a top with the Mikunis jet sizes just needing the conversion so she will do the same with the Keihins ! Thanks in advance Sent from my iPhone using Tapatalk

Well now that everything is perfect on this little guy - I need to let her go to someone younger that enjoys going fast still ! Pm me for more info - I'd like to get $3700 OBReasonableOffer. Completely rebuilt from the bare frame up. Bike has 0.1 hours on it since rebuild. Arkansas delta region Sent from my iPhone using Tapatalk

This go round - I lapped both jugs, and lapped the intake surface to a nice surface and mounted everything up w gaskets and a very thin layer of yamabond. Zero leak down. So it was either the intake gaskets leaking on round one - or the head, or both. I will try to post a video of the piston. I've personally never seen a piston look like this one did - and I've seen a lot of messed up 2 and 4 stroke pistons haha Sent from my iPhone using Tapatalk

Well the great news is she's still running ! The other news (not bad) is I've got some jetting to switch up. Got a nice set of 33mm PWK's from a member - but with my cylinder/porting/setup it's getting a little too much fuel, which is what I wanted it to do for break in but now I'm wanting the speed back I had on the first set of pistons haha Sent from my iPhone using Tapatalk

^ yeah I just got a set of 33 PWK off a fella on here. They look and run great just got to get the jets right so she will gin a little better Sent from my iPhone using Tapatalk

Well back to roll out Take 2 hopefully this one fares better than the last ! Sent from my iPhone using Tapatalk

Naw I've got some Mikuni VM34 carbs right now. Not the best but it ran damn good until it popped that oring and smoked that piston. I've got some muriatic acid in going to clean that cylinder with this wkd - try and get the studs out of both jugs to lap them before I attempt to throw it back together - and will do a leak down this go round for sure !

Kinda what I thought ^^ lol Sent from my iPhone using Tapatalk

It's got 34mm right now - you recommend going down to stock size carbs for a ported motor ? Sent from my iPhone using Tapatalk

Which Keihin carbs are the shit ? I'm still gonna order some just don't know what jets/size would be optimal for a ported 66.5 engine Sent from my iPhone using Tapatalk

Any idea what brand these are ? We're on it when I found this sleeper jarm Sent from my iPhone using Tapatalk

Let me see if I have some port pics. It's bored to 66.5, ported, gonna have a 21cc dome Noss head, and CPI pipes. here's to the top of the exhaust port Sent from my iPhone using Tapatalk

I may just clean these VM34 up real good and go through them with a fine tooth comb but man they were spotless and the overall shape of the carbs is great compared to some stuff I've seen. The cables aren't as tight in the top as I'd like but that's what the rubber boot is for I'm imagining Sent from my iPhone using Tapatalk

Wanting some brand new ones I don't have to do anything to really besides jetting maybe. Sent from my iPhone using Tapatalk
