Rough cost on pumper?


Am trying to source a pumper carb in the US, and being from Asutralia this is a bit tough. Having a little trouble finding someone over here with them, and thus far the parts from the states have been way cheaper. Given my two young kids and wife monster, that is a good thing. What roughly are the Mikuni's and Kehins worth new??? So far I have a price of $600 for the FCR which seems a bit high...

Oh yeah, the crankcase vent on my bike looks pretty decent, about 20mm (4/5 inch) outer size from the top of the case to the inlet. Is this really restrictive, it seems pretty well sized to my limited intelligence.....


The cheapest place I've found for the Mikuni pumper carbs is

Here in the USA, the KLX300 crankcase breather hose has a restrictor inserted in the hose. That is the main cause of low air flow.

Ride on


Thanks Brew,

Those prices seem much more reasonable. You were right about the hose, mine had the restrictor too. Not any more!

Thanks again for your help,

      Hi I was looking at a clean 10,000 mile 1993 KLX 650. the're selling it for 1800, and I was wondering what the availability of parts to keep this bike running as a daily commuter, and adventure tourer are like in 2018. Should I buy? I don't care how cool it is, I just want something that I can keep running for a while, and fix whatever issues may arise. Any help would be appreciated

      Hey all, Im hoping to use a front wheel trailer hitch mount to tow my KLR 650 from CA to Utah. Ill be towing for around 700 miles. This is my only option. My concern is if the final drive bearing is lubricated by transmission turning. If the Klr is, won't I burn out the transmission? Ive attached a picture of the hitch mount. Would love to hear some peoples experience or knowledge on this. Thanks all.

      Great day or riding in Richloam (aka Withlacoochee National Forest). Sandy soil was damp, so it made for epic at speed powerslides!

      Hey guys, looking for some help here.
      I'm interested in buying a 1993 KLR650 i found on craigslist. The owner says that compression is good, but that there is no spark at the spark plug.
      Any idea what could be wrong with it? any experience with this before?
      I'm not afraid of getting my hands dirty. I'm excited about having a project, but i don't want to dump a bunch of money into it.
      All I can think of is grounding issues, maybe a bad stator, or oil in the spark plug wells from pad valve covers.
      Anyway, i'm a noob when it comes to motorcycles. Any ideas how i could find out what the problem is or anything to check for when i go look at the bike?
