smokey blaster

pnd · #1 (**permalink**) 05-29-2006

hi all. just bought a blaster 2005 model not long ago(stock engine,no mods) and there is always lots of exhaust smoke, it is not using pre-mix. looked into the carb and has a lot of oil lying in it, could i have an oil pump problem? many thanks for any reply

Check the Spark Plug if it Oily black color then u have to adjust to increase the fuel amount by either opening the needel valve or by putting a bigger jet..

Clean your carb out and block off your oil pump. I just recentyl removed my oil pump and wish I would have done it a long time ago! I had one of the oil lines break about 3 years ago and caused me to have to rebuild the top end. I just got the thing running a couple of months ago. I removed the oil pump and used a new gasket to trace a piece of steel and cut a cover for the hole it leaves. You also have to plug the hole in the carb where the oil is supposed to be injected.

checked the plug and it is oily and loads of carbon build up. removing the oil pump was an option but would rather leave it on until i have tried other things. any idea what size jets are supposed to be in, then what size should i try??? thanks guys

Stock Main Jet is #230. I am running a #260. If the plug is that oily and the carb is full of oil, change the plug and clean the carb out really good. Blasters run good on NGK B8ES spark plugs.

Actually I don't know shit about blasters, but have heard even a Yamaha Tech say that it's best to buy the oil pump blockoff kit and switch to premixed gas. Sounds to me like you need a bigger jet and maybe lower the clip a notch on the needle towards the pointed end and probably change the main jet.

wait wait i thought if the plug was wet (oily) your jetting needs bumped down.

Yep it's alright depending on the oil... 25ml/1liter is 40:1

Personally, I'm running 50:1 with amsoil dominator in my R

40:1 is good for most oils. I always mix 40:1 for trails with benol
