MZ/MuZ Riders

I have and 05 Baggy, it pops somtimes on downshifting, and when it does it usually stalls if im not fast with a blip of gas, What rubber surround are you speaking of to get this cleared up

Sounds as tho its running lean. Are you running an aftermarket exhaust ? This would throw out the mix, and if so you wouldn't want too remove the rubber strip ( take off seat it fits to the top edge of air box) as this would let in more air and lean it out even more.

so will a jet kit help or hinder, and does it make more power

A les restrictive exhuast, jet kit and some dydno time to set it up will give more power from the standard motor. You will also use more fuel, its a trade off that only you know is acceptable.

I've just bought a 2002 Mastiff, a little tatty but not beyond redemption

I've only had a few miles test ride on the bike before buying but took it easy as it's been laid up a few months and the chain and sprockets are shot. No eveidence of lean running but it does have a Micron can (rather free flowing if you know what I mean ) and the rubber air box seal has been removed....or should I say....lost??!!
Tail pipe is a little sooty but that's as it's been sat for months with just the occasional startup and warm through (I've started a thorough service on it now).

Anyway to the point........do the guys running a Dyno have to be familiar with the bike to set it up or is the process completely down to gas analysis/power output/delivery monitoring etc? Think it would be wise to have the bike looked at as the history is sketchy Motor sounds sweet but I would like to make the most of it.
Also, any recommendations who to see for tuning/performance setup? (I live in Zomerzet, South West UK)

Thanks

you would do much better with someone who knows our carbs. Slipstream in the UK seems to be the guys to know....

Thanks again.....is this them?

The air screw should be about 5 1/2 turns out from bottom (at sea level), the EVAP system should be removed asap, it sounds clogged from sitting too long at the warehouse muting the idle fuel signal (closed butterflys and massive vacume from the down stroke of the piston should in theory give plenty of fuel), BUT with the evap system in place all of the engeneering that went into the carb setup goes out the window thanks to the D.O.T. / EPA. Do that (if you havent already) and you should see a vast improvement.
