    Ollie could answer this best I guess, but open to all opinions…

    I test rode the 300 on Saturday. I liked it but was put off by one thing..
    I found it didn’t cleanly progress into band. Is this normal or was it a jetting problem.?
    It was under light progressive throttle when it occurred. If you gave it a handful it didn’t do it , but then you had more then you needed in power..
    What do you think?

    Or was it my riding style:S

    I know Ollie’s been talking about his jetting for sometime, him and Gasser maybe can give you a heads up. Question for Ollie, once you get your jetting right, can you expect that it will be ok at most locations for most conditions for most rides?

    JRD,The Gasser should be giving you a smooth almost 4 stroke like transistion, The power band is not as aggresive as say a KTM which has a MX type “hit”,As TB will testafy my bike just torqued up a steep slippery hill last weekend no problems at all.Im having jetting issues at the moment as I like things to be spot.My problems are in the 3/4 throttle position where it stumbles probably a bit rich on the main at the moment, usually when its right it should just be a case of adjusting the air screw when required for the different temps encountered,other than that nada.I will post later a number of different peoples jetting setups and that should give you some indication of what you should try.
    if the bike you were riding was a test bike surely the dealership would have had it jetted right you would think?:unsure:
    the symptoms sound like an overly rich pilot or needle position,ie as the throttle is cracked open more air is allowed to pass which inturn leans out the mixture,anyone can correct me if they think that I am wrong:unsure:

    I will try and ride another one and confirm whether it’s the bike or me…
    It just didn’t feel right.. I would have thought you could bring the revs up and bring it into band under light load without spluttering..

    yes you should it definatley sounds like a jetting issue.The way a bike responds to throttle application is a personal preference,I like to be able to torque thru the crap but also be able to snap open the throttle and get instant gratification when required

    I have just bought myself a #42 pilot jet from procycles @ $22:angry:to try, but they didnt have a 172 main which i want to trial also,might give show and go the Keihin importers a go, That should get it close to the Mark, Damn I hate being a perfectionest:laugh:

    I am running a size cek needle second clip from top 78 main 38 pilot and a norside power valve cover.I found this set up works for my riding style.this gives me a very smooth power delivery with no hesitation or spluttering at all.if you were after more aggressive top end i would be looking at a 250cc exhaust.do a lot of research before running a 172 main
