I'm about to install Bill Blue's 351 Big Bore kit with the 36mm Mikuni Flat Side TM carb on my '09 KLX 250s (existing mods: FMF Q4 exhaust and power bomb header; 13/44 T sprockets; K&N air filter; removed snorkel; dynojet stage 2 kit). I ride on the road mostly, to and from work, but hit trails whenever I can find them.
Can anyone give me any tips or suggestions before starting this project? For example, is there anything I should look out for or anything I should have on hand to make the job as easy as possible? I have a stand, the tools, and the knowledge.
In addition, I'm wondering if anyone can answer the following questions:
Will the 36mm Mikuni carb fit with the stock carb boots? Is this the TM36-68 everyone talks about using or did I order the wrong model? I know Bill sells a custom TM 33/34 Mikuna, and that fits the stock boots, but I also read on a thread here that the 36mm Mikuna fits as well. I'd just like some confirmation of that. Any suggestions on gearing? I have been running 13/48 T sprockets, but am about to put on a 44 T rear for better highway use.Any suggestions on jetting? I have the dyno jet stage two installed on the stock carb, and hope to reuse that needle, jets, etc. I am at a very low elevation in Charleston, SC: ~20ft above sea level! Many thanks! Any tips, answers, or suggestions are appreciated!
Edit: I already have the service manual and torque wrenches.
