i have not yet.. break it in as I have a race in a few weeks and very limited time to get it ready.. actually im breaking it in as I type this.. the 2135 pipe is nice tho.. in between the 9901 and 9853.. has a nice sound to it.. the tear drop design head looks pretty nice also..

on the mephisto the crank does not have silicone in it.. might be a nice added feature. got a bunch of running in on it and found the 41021 header and 51007/2135 to be the best for tune.. the 41021 header and 9901 pipe was about the same but needed to be 1-2 hours richer on top and 2-3 richer on the top to have same temp and idle/clear out on top end.. power band felt pretty close to the same for the testing we where doing..
I tried the Odonnel 97Ts in a couple of my Nova Rossis for a while but I didn't like them as much as the Nova plugs.
I'm kinda curious how your plugs will work out.
How about trying it and update us?

next weekend I will test those combinations out.. its 22* and snowing out here in wi usa.. but a long 7 hour drive next week to test for 2-3 days and will have a better answer also..
on plugs I have been using the gsr p5 plugs and in the really cold temps the gsr p4.. basically os plugs.. the gsr 5 is pretty close to the ct06 nova plug but half the cost

Hey guys, I've got a fairly basic question (hopefully).
Couldn't quite figure it out with Google.
The 28-7 and 28-8 are both available with a rotostart option (for a Savage MT) BUT what the heck is the difference between them aside from port count? Thanks in advance.

monty will have my mehisto right away ill see if i can get the numbers once he has it.
well scratch that I guess nova direct USA refuses to ship to monty and talked crap about him in the process, not very cool.

Ok after reading page after page on engines and tuning i think im even more confused. I read that novarossi motors tune different? How so? I also have a 2 stage idle but motor runs pretty good is that just how these engines run? P5xlt 9901 40210 ct06 plug 30% byrons

That is exactly what i was looking for! Just have to get on the track to tune the top end. So with novarossi tune bottom end first then the top on track? I still think my idle can close a bit more its 1 turn from closed looking down the carb. Temp was about 240/245 running in my yard witch is pretty much sand/dirt.
