Hi,
Spotted a KLX suitable carb on Ebay.

current bid $100 buy now $175

Later carlb

 

In reading the description of why he is selling it, the AP on the FCR35 also sits very close to the exhaust mid-pipe/header. It is a non-issue, assuming that's the only reason it is being sold.

 

How can you say it's not an issue when he clearly states it rubs on his Muzzy? Can you explain how it's not an issue?

Thanks

 

The accelerator pump protrudes out from the side of the carb and it sits very close to the exhaust pipe. I guess you could actually push it into the pipe so that it touches if you wanted to. I took it to mean that he was worried about the heat from the pipe. I'm saying that is a non-issue. From my own direct experience and that of lots of others.

 

Just to add, if anyone is considering bidding on this carb and wants a close-up photo of this, I can take one this evening. I don't know if the FCR35 that I have and the FCR37 in the auction have the same body style or not, though. All I can comment on is the AP and the exhaust - it may have other issues not stated in the auction. The FCR35 is definitely a tight fit, though. The way I have my carb in the boots, the accelerator pump sits about 1/8 of an inch or so away from my exhaust pipe. I've not experienced any issues with vapor lock, fuel boiling, or anything like that, and I've never seen any similar reports from others running the FCR35.

 

Nothing a bit of exhaust wrap wouldn't fix. Good deal on the carb.

 

Would this make it a wheelie machine?

 

Maybe tremor38 or Marty can comment better on that. I only installed my FCR35 after I had the 331cc overbore, so I don't have direct experience with using the pumper with the stock 250cc configuration. I will say that when I had my 331cc installed and compared the stock CVK carb vs the FCR35, the difference in throttle response between the two carbs was very noticable, and that I was much more easily able to simply crack the throttle in first gear, no clutch or body english, and the front end comes right up. You can do that easily enough using the clutch in its stock configuration, but I was never really able to pop the front using just the throttle alone until I did the pumper / big bore combo.

BTW, here's a photo of what I think the e-bay seller is talking about. I could be wrong and if I am and you buy it, I take no responsibility. But if this is all he is worried about, then I'd say that is a great buy because the carb being close to the pipe is not an issue at all, at least as far as my experience has been. The disk sticking out with the brass tube and little rubber boot on top is the accelerator pump and plunger - it is very close to the carb and if you rotate the carb in its boots, you can easily make it rub the pipe. You can see that I've got a little gap in mine.
