Probably going to need to rejet the carbs on my 78 (bs38 carbs), where should I buy the bigger sized jets?

I prefer genuine Mikuni jets over the knock-offs. I just think they're better. If you shop around, you can get them for pretty much the same price as the repros so why buy copies? One repro brand especially to stay away from is RD. They're cheap but don't fit well. They feel like they're cross-threading when you screw them in.

You may be able to get Mikuni jets at one of your local shops. Check around at ones that deal in dirt bikes or snowmobiles - those guys are always rejetting. Chapparal has them for a good price and so does this place ....

There was another place but I can't find the link right now. I'll keep searching though as this place had a great selection and prices.

I got mine from the link 5twins posted. It took a little bit longer than expected to get them, because 1 jet was back-ordered...but the price was good and they respond to emails quickly.

Bigger jets are not always the answer...proper mix screw settings and proper transition to the main needle with maybe the next sized MJ is usually the answer.......proper transition to the main needle is really the answer....moving the c-clip from one notch to the other is usually way to much.........even a couple of thousands is important.....as for me wouldn't know much about that after 40 years of dicking with it..............
