have decided to go with a 172 kit on my t5, il be using the standard carb and sterling right hand exhaust atm i have drilled a hole in the heart on the filter and its currently running a 116 main jet and standard timing, what timing should i use and wheres a good starting point with the jetting and mixture screw? cheers

125 main , screw 2 turns out. leave timing as it is . if on a long run, stick a bit more oil in tank .

cheers thank you and im assuming thats if the timings spot on for the 125 end itll be fine for the 172 top end? cheers again

I backed mine off a bit for the 172, but T5"s run low timing anyway, 16 degrees or so, so just put it back to normal about 5000 miles ago, havnt had a problem since.

I always set mine as per the malossi recomended spec of 14 BTDC.

this question of where to set the timing up on a malossi 172 kit comes up all to often ,and tbh i just dont get it ,its as if folks just do not read the instructions given with the kits or just would rather second guess malossi,s extensive research and development and basic advice thinking that they somehow know better .
just why would you leave it at the std 16 when adviced to put it at 14 by malossi themselves .

best power band if you retard it to 18° with no real risk of seizure....

ive anti clockwised mine about 1.5 mill is that right

well not according to malossi or the info provided in the SIP catalouge ( they also advise 14 to 16 )lol...but each to their own i guess .
it may well feel a bit better lower down the rev range at 18,but i would expect it to suffer at higher revs on that ...guess it also depends on your level of tune and exhaust used .

were should it be then matched casings cut ported and polished crank stock carb 130 main jet and a mk 1 taff pipe so can ya tell us mate how far to turn my stator
