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

Something like these ? Sent from my iPhone using Tapatalk

Just trying to figure out anything and everything that could have caused my malfunction. Just never had this kind of problem on outboards. Ever Sent from my iPhone using Tapatalk

These old Mikuni VM34 look like a POS the way the floats slide up and down on that needle. Seems to me it would get jammed up and run the carb out of fuel easily and that obviously ain't what I'm after haha Sent from my iPhone using Tapatalk

Alright last question - what's the best 34/35mm carbs I can slap on this motor I won't have to mess with again for a little while anyway ? Sent from my iPhone using Tapatalk

Good luck man. I've got an 87 that's been a little nightmare Sent from my iPhone using Tapatalk

Well I called a few places and this fella called back first. Explained what I needed and seemed legit. $230 ready to bolt on wasn't bad either. Just gotta figure out some new gaskets and build a leak down tester to use (which luckily I have all the parts I use to pressure test the tanks I build laying around). So hopefully next by the middle of next week - I'll be back in the saddle for another 11 seconds aka two pump chump Sent from my iPhone using Tapatalk

Well damn - that's gonna suck if it doesn't have all the parts I need. Ordered a new Noss head, 21cc 13* dome. Real nice fella we talked about what all I needed so maybe this thing will get me in the ball park Sent from my iPhone using Tapatalk

I ordered this one. Hopefully that gasket will come back off relatively easily Sent from my iPhone using Tapatalk

Yeah I messaged them on eBay. I'm not looking for a anything besides a motor that will run long enough just to play around with lol. Never would have thought there was that much to the dome design for one of these little motors to either blow or stay together haha. When you fill these things with coolant - is there a special way it has to be done or just fill them? I took the hose off the top of the head to allow any bubbles left over to get out and then put it back on - it's got a billet water pump impeller in it and new bearing/seals to boot. Only hearings I didn't replace were on the crank Sent from my iPhone using Tapatalk

I emailed Chariot and asked them about what they could do for me but haven't heard back from them yet either. Sent from my iPhone using Tapatalk
