Proper jet size

[shortcal]

2001 elite. new variator/weights/r1 muffler/ oil pump is tied open. Now Im not 100% about this whole jet business. Runs well hits a little over 40. Im assuming it needs to be bigger perhaps someone could enlighten me if im wrong? what size should it be at? Is my engine gonna be ok without rejetting? I would personally rather not get in there and tinker with the carburetor if i dont have too.

with a set up like that i would get a performance air filter and a set of gears and up jet it and you will be good to go

I would disagree. stock carb will not handle open filter very easily, usually end up boggy with little gain. small upgear wouldn't be a bad idea though

With an R1, you're probably okay, but do some plug chops. Check tech docs or search for how to do it, very easy.. then you'll know if you need to upjet or not.

Yea, do plug chops, you dont want to run it lean and melt the engine.

would do the airbox mod and then slap in a 90 main with that pipe. a 9.0 gear will run about 50 mph and it will get decent mpg also.

where might i be able to get a larger jet? My honda dealer is saying the highest he can get me is a 78 and I dont have a drill or bits or anything to drill a larger one

Here is what I did. Take the part number for the largest jet you can find. Looking at the number you can see where the size is coded. Change that to the size you want and google the number along with "honda". I found a mower place that had 80 and 85. Some of the Honda power equipment use the same style jets in different sizes than came in the bikes. For my Pal (Spree sort of thing) I've found 63, 65, 68, 70, 75, 80 and 85. I found part numbers for smaller ones but I'm not going that way. Gotta love that internet.

They are perfect for jets!

There's info in adv tech docs here on drilling out jets if you decide to go that route.
