Hey folks, new to the forum,
I’d like to start by saying thanks to everyone who contributes to this community, it’s been a big help for me so far when looking up upgrades and sourcing compatible parts. I know that there are loads of threads on jetting, but I bought a blaster with a few mods and I’m hoping someone with more experience can help with getting a jetting baseline with those specific mods in mind.
I just recently found a blaster for a pretty good price, I had one back when I was in my teens and it was too good of a price to pass up. (2006 for $600) small price to pay for the nostalgia this simple little machine gives me!
It came with the air box cover removed, k&n air filter and had a Fmf gold exhaust system/silencer and booysen reeds. When I took it for a test ride it really ripped, but it sounded on the lean side.
I pulled the carb and gave it a good cleaning, deleted the oil injection system (not because I’m worried about it failing, I just find it easier for carb tuning) and I noticed the main is only a 230. I believe (correct me if I’m wrong) that is the stock jet size? I’m new to blaster tuning but even I thought this was a bit small for the mods it is running.
Any thoughts/ballpark ideas on which jets I should start with for baseline jetting before I start plug chopping?
My elevation is 2200ft, and the temp is on the chilly side up here in Canada.
Compression is on the low side.. 115psi, I’m hoping to put off doing the top end till sledding season.
Thanks! If I’ve left any useful info out please just let me know!
