Rejetting
I am going to see what jet sizes I have this weekend and I have already purchased a 45 pilot/slow jet and a 175 main jet. Is it possible to install the jets while the carburetor is still on the bike? AND just wondering if you guys have any additional tips for me.
Thanks for your time

I've done it with the carb on the bike, if you have the stock air intake it's kind of hard to get in there, but do-able. If you can remove the air cleaner, it will make things easier. You just need a screwdriver, I think I had to use a short, thin one, there are 4 screws. Either drain the carb of fuel or shut the petcock and run it until it shuts off, the bottom of the bowl will still have a little fuel either way, so take care not to spill any on yourself since you'll probably be laying/sitting on the ground under it.
Stock should be 42/180 I believe but if you have aftermarket exhaust and intake, you might already have a 45 in there. The jets come out with a flat screwdriver, don't use any loctite or anything on them.
You should get a service manual, there are some good exploded views in there showing how it all goes together.

I've switched them with the carb on but the 4 original screw heads will strip easy so be careful. I switched them out with the stainless steel allenheads that were on that link that you saw yesterday. When you take the jets out, shoot some carb cleaner up there. Let us know what you find

Thank you for the information, yes I do have a service manual and it says 42/170 stock but since the mixture screw does not have the cap on it anymore makes me believe that the previous owner has already worked on the bike so we'll see what the sizes are this weekend and I'll make sure to put a post in this thread. I will deff take off the air cleaner, thats not a problem. I was just wondering about the specifically about the carb, thank you again
rooti is right about the screws, they seem pretty soft. If I ever take the bowl off again I will take one of the screws down to ace hardware and get a thread/length match in stainless steel socket head cap screws. Carb cleaner is a good call too... can't hurt.

If you are doing this for the first time you will find it easier to work on the carb with it disconnected from the bike. You are working in a confined space while it is on the bike and can't see too well what you want to work on!

True, but after working on cars ( lots of confined space), working on a bike is Heaven lol
