Looking to jet a 82 wr carb. for restore. Has vforce reeds and a Geoff Morris pipe.
Yes i have seen the charts for standard jetting but looking for feedback on whats working. Now I know the cylinders change each year but can we also look at what in your 250 carb for 83 84 I have a 1984 wr cylinder ro be installed soon also. please share feedback

Need to order some main jets , needle jets and needles to jet in these 250s I know 430s but 250s I have to learn major ranges shown for needles and needle jets have me asking questions what I need. Whoops lets not forget the slide you are running

Gary,
In my 83 250WR I run 38 mikuni, 2.5 slide, needle jet is p-2, 6F16 needle, clip in #2, #30 idle jet, 350 main. This is with 40:1 maxima oil. The ADR was 95.1. or density altitude at 1676ft. Runs very clean, no messy tail pipe or excess smoke!

Thank you Marty. ( ps he has some great husky stuff ) Please look at all the posting on form the 250s below is the 82 first and 83 years second chart. I think you all can see why I posted the question. Look at how many levels lean the P8 needle jet vs the R4 needle jet The P is much leaner

Here is a link to a Swedish page with some info about the std jetting from the factory.

Gary,
My 83 250CR, had this set up: 45 pilot 2.0 slide 430 main w/stock needle? I moved clip back to center position,...then and I changed the main to a 380,
for Unadilla, ran much better. Once i dumped the stock silencer & put on an Answer , & that was the best change i made.

Nice chart on that euro husky site. I just still comparing that big change to the needle jet between models. I will go rich with the cr jetting and needle jet numbers and work my way down. Bike will be at dilla if all is good on shipping Using the wr cylinder porting

Needle jets are different... so are the needles...

 

[GaryM]

Wow , where did you find this chart. These are the exact comparisons ! Now for my brain how can I figure out what I am seeing. So - husky much went leaner on needle jet for the wrs vs crs and then changed the needle to let in more flow and /or deliever fuel at different time? Now the later 83,84 engines have bigger more open ports, yet carb jets much leaner if looking at all the husky charts show on Bryll link. ( good to see Bryll on site again )

I am thinking we or I am leaving a lot of preformace setting untapped in my other huskies too!

I used a few of the needle and needle jet numbers given in the link to the Swedish website and plugged them into a spreadsheet I found on a forum... took a little research to get the Mikuni needle and needle jet specs...

And yes, it looks like Husky changed "assemblies" to alter the fuel curves.
