Just a question for anyone on here could I drill my own jets if so how do I know what size bit too use I have a 90 main front carb jet and a 20 pilot jet in front and rear is 87.5 main and 20 pilot need to know what size I would use its abit hard to find some one in aus who does a cheap jet kit so if I can do it myself cheaper then I would give it a shot
That seems like a horrible idea, have you got your carb model number to search for jets with, it should be interchangeable across the manufacturer of the carbs
You can get jet drills bits they arnt cheap but u want to make sure you right as once done can not be undone!!! U use a hand piece and drill by hand
As huntsman eludes to , jets arnt bike specific they are carby specific so to speak I believe they are Mikuni BDS26 carbs http://www.mikunioz.com/mikunioz.htm http://www.jetsrus.com/ http://www.motorcyclespareswarehouse.com.au/
http://www.ebay.com.au/itm/NEW-MIKU...orcycle_Parts_Accessories&hash=item4cfd73201e I would get a 92.5 and a 95, so you can try 90 on the front and 92.5 on the rear, then you can step up if you need to. slow jets are pilot jets and should be ok you can adjust the mixture for those with the screw anyhow.
double check measurements for the actual size of the jet but i have part numbers for you, Below is the mikuni part code for the jet N100.604-xx (xx is the size jet you would like) so in your case N100.604-92.5 N100.604-95
LOL, I concur. I just bought some "rare" jets from wemoto for $3 each. Not worth rooting around drilling unless you have absolutely no choice.
Why do you want to drill the jets? What makes you think that you need the bigger jets? Is engine running lean or just not happy?
seems to play up under pressure fine down low but anything over 40 coughs and splutters bad not sure if its only a airbox issue or not as it dosent have the filter part on it at the moment so just getting straight air also got straight pipes on it am also not sure on float height a guy from another forum messaged me the other day and said the manual was a misprint its 7mm not 17mm they need to be set at bit confused
