Bansh-eman Posted January 11, 2007 Report Posted January 11, 2007 34 PJ's are big enough they are just an older carb... they where on honda dirtbikes in the 80's... the PWK has much more throttle response and seem to use less gas then the 34pj... i had the pj's and talked to a few other guys that had them too and we all seemed to use more gas with those then when we got 35pwk's Quote
Animalman294 Posted January 12, 2007 Report Posted January 12, 2007 Most people are running the PWK's, but to change 1mm you should just try what you got and see how you like it. There is also another thread on this right now you may take a look at that............. Quote
dajogejr Posted January 12, 2007 Report Posted January 12, 2007 I ran 35PWks on mine and loved it. I don't think I'd spend the money without seeing how the PJs run on it first though... If you're getting a cub, gas mileage/usage really isn't going to be a concern. It's going to drink it...period. Quote

Yep, you'll be alright with the PJ's Quote
bigboybanshee Posted January 12, 2007 Report Posted January 12, 2007 Cleaned up cub - 34's/35's would be ideal Drag ported cub - 39's :beer: Quote
