I've just put on Megadella Compact XL 8 cone, MRP reed housing top and VForce4 reeds. Trying to setup carb without pump... or am I just better off changing to pump?

With the Mikuni tmx30, the quattrini in the auxiliary nozzle also needs really fat compared to the mhr 

 

less with the main jet. 

what is your carb jetting with the TMX 30mm? are you running a fuel pump too?

Would be very interesting to see some dyno curves, if possible  .

What are your port timings?

untouched from factory.. 2mm base and 2.5mm head packers

Interesting what is being worked out here again.

Immediately have a guilty conscience with my hair dryer processed hood ...

 

 

I should have the viper box by the end of the week for me to try on my 260.. and also just got the megadella XL compact 8 cone to try too.

just finished building a new performance engine and have got oil leaking out of the clutch cover breather. it's not just a little, it's enough to trickle down and hit the brake backing plate within minutes. so it's an S&S cover that's been milled out and an MMW basket, nothing unusual. gearbox oil level is also correct. anyone else had to deal with this issue?

it's probably on this page but lots of pages to go through ....

just finished building a M260 with VR1 cases and polini box.

is there ballpark jetting for 30mm phbh please?

Anyone have cylinder temp readings on their M232? I am running one one my PX with 24/24SI and SIP performance pipe...I'd like to get an idea of what CHT you guys are getting?

Yes Nick.

Standard air filter and air bellows.

I have tried the polini venturi and pinasco carb box lid but I think I need to get it all running smoothly first before I delve into more performance bits!

I understand. They are a helpful tool for setting up a motor and also I find them a good tool for highway riding as to keep a check on the motor, especially in Australia where summer can be quite hot.

Cylinder head temperature

PolifkaRudl, are you running a CHT?

Fantastic. I will start at 18deg and work towards the recommended...and yes, kytronic has a vespatronic curve...7 from memory.

Thank you guys.

PolifkaRudl....That's great advice, thank you. What about ignition timing? Any advice on that?

Thanks for the reply Truls221.

I'm running a SIP XL.

The jetting is good...I've just been on a 300km/h trip last weekend and it performed well except for that little stutter at light throttle.

Looking back on the weekend, it does just keep up with well tuned Malossi 210s but going up long hills, it'll leave them for dead.

I will look into doing the rotary pad. 

Is there anyone on GSF who is running a similar setup that would share their specs?

That's great MaRi, thanks for the reply.

I'm happy to rip apart the motor again to do the rotary valve but I guess I need some specs as to how much I need to take off? Quattrini had no instructions with the kit so rather than hack away unknowingly, I stuck to stock.

there was no instructions with kit so rotary pad was left standard

Hello GSF. I've just installed a M232 on my PX. I have match ported the cylinder to the cases and am running standard ignition (have kytronic unit too) currently set to 24deg and curve 7, SI24/24 carb with drilled out float chamber passage 2mm, SIP #4 slide and DRT #7 float chamber top lid, 160/BE3/132, 55/160, SIP XL. My issues are that it is a little stuttery at light throttle and it hasn't the power that I would have thought it should have. Can anyone tell me what I should be looking for or see anything obviously wrong with my set up? My thought would be timing but not sure...thanks in advance.
